[Q] Completing Root Process

I'm trying to root my Rogers One X running 4.1.1 using these instructions, howtorootandroid.org/2013/05/28/how-to-root-htc-one-x-step-by-step-tutorial/ (as a new user I'm restricted from posting actual links).
I've got everything completed to the point where it says to disconnect the USB cable and select Recovery from the HBoot menu. When I select that, the phone reboots to the home lock screen. The next step says to go to Backup and backup the system partition. Problem is, I don't know where they mean when they say go to Backup. The only Backup function I know of is in Settings and that just backs up the Google user account data. How does one backup the system partition? Is the phone supposed to reboot to the lock screen from the Recovery prompt? Or is something going awry in that step?
After that it says go to install and install the SuperSU.zip file. Using a file manager I can locate the apk for the Superuser app and it installs but when I open it I get a message saying "There is no SU binary installed, and SuperSU cannot install it. This is a problem!" That last part seems obvious.
Thoughts appreciated on how to resolve.
Thanks.

Stop what you're doing, you're using a root process for the wrong device. That's for the quad core One X, if your phone is a Rogers phone then it is the dual core version. To be sure, go into your bootloader and tell us what it says there, only the top four or five lines. To get into the bootloader, simply power the phone on by holding the power button and the volume down button at the same time, keep holding until it boots into a white screen, that's your bootloader.

Thanks. Don't need to go into bootloader, just checked the device hardware information and you're right, it's a dual core. Using the volume + power buttons won't go into bootloader. I can get there with the Hanson2000 utility. The items in the Fastboot USB menu are Bootloader, Reboot, Reboot Bootloader and Power Down.
Through the process I used last night, the bootloader is unlocked and I haven't bricked the phone.
What's the process to root a dual core version, then?
Another question. Since the bootloader is now unlocked, do I need to continue to finish rooting the phone? With the bootloader unlocked, I can install custom ROMs, right? That's, ultimately, the goal. I'm trying to be able to update to 4.2 or 4.3 which, I've been led to believe, will also enable full USB host functionality on the phone.
Thanks.

Essentially you've done the hard part now. All that is left to do is install a custom recovery, and then you'll be able to flash custom ROMs from within that recovery. The AIO kit only has the ability to install TWRP 2.5 I believe, and that version is riddled with faults. So below I'll outline how to install a stable version.
Download TWRP 2.6 from here. You'll need to flash it manually using fastboot. So once you've downloaded it, put it in the same directory that adb and fastboot reside in on your pc and connect your phone. Now you need to open a command prompt from within that directory (shift + right click opens the menu, then select open command prompt here). Enter the following command:
fastboot devices
This will make sure you're connected properly, hopefully it will return your device serial number. Now you want to enter the following commands:
fastboot flash recovery "filename.img"
(the exact recovery filename, minus the talking marks)
fastboot erase cache
fastboot reboot-bootloader
Now you'll have a custom recovery which you can enter by pressing the recovery option on your screen. Now it's time to select the ROM you want to try and download to your pc. Once you've done that, select mount from the recovery menu, then select mount usb storage. Your phone memory will now show up as a removable drive on your pc and your can copy a ROM across.
Before you flash a ROM, make a backup of your current setup, you can do this by entering the backup option from the main recovery menu. It's essential to backup the system partition in case something goes wrong in the future, you can easily restore it.
In terms of ROMs, only EVER download ROMs you find in our forum. Never download from a different device forum or from another site, that's a surefire way to brick your phone. Your two options are Android Development, where you'll find Sense based ROMs, and Original Android Development, which is where you'll find aosp ROMs.
Once you've copied a ROM to your phone, simply perform a full wipe in recovery (cache/dalvik cache/factory reset/system), do this by going to the wipe option, then advanced wipe. Just don't wipe sd card. Then you can select the install menu, and find the ROM on your sd card, and install it.
Your phone is s-on, so you'll need to perform one extra step. When you download the ROM, within the root folder of the zip file there is a file called "boot.img", you need to extract this and copy/paste into your adb/fastboot directory. After the install process has finished in recovery, go back to the main menu and select reboot, then select bootloader. When the phone reaches bootloader, make sure it's connected again and issue the following command:
fastboot flash boot boot.img
Now you can reboot your phone and enjoy the ROM. Please note, you will need to flash the boot.img from each ROM you want to install. Unless you decide to get s-off, which removes that need.

Actually, AIO allows you to use the TWRP, ClockWorldMod or your own file. I downloaded the file you linked and WinZip says it's an invalid archive. Can I use CWM instead?

It is suggested that you use TWRP, other recoveries are known to have bugs. Don't worry about what WinZip says, just check the md5 and as long as it matches the md5 listed on the download page it's fine.
I'd also suggest doing it the manual way as you actually learn something during the process. The time will come when one day you need to do something manually, and it's better to have a little experience than have to learn at zero hour.

Don't get me wrong, AIO kits are convenient, but they're also a big part of the reason why people have absolutely no idea about what they're doing to their phones, or how to recover if something goes wrong.
Sent from my Evita

Problem is that WinZip shows no file when it opens the archive. Can't do anything with it.
I understand your point about doing it manually. I'm a photographer and an end user, not a programmer and don't do code well. I can likely manage getting the recovery installed but took a look at a couple of the custom ROM threads and have no idea what the people posting the threads are talking about insofar as some of the instructions. I just want to get the phone able to operate as a USB host.

It's not a zip file, that's why. You're not meant to be able to do anything with it on your pc. Check the md5 like I said and you'll know the file integrity is good. Then you just need to flash it as per previous instructions.

Sounds like he wants a rom with OTG support

Yeah that's what I was thinking.
Sent from my Evita

Yes, I do want a ROM with full OTG support. It's getting there that's the thing. Stock, it has USB storage capability and some devices (mouse/keyboard) but not broader for things like cameras.
I'm sorry for the problems. Remember I'm not a coder or a deep 'inside baseball' guy. When a file shows up on my computer as a zip file, I think I need to unzip it. I don't have the first flying flipping clue what md5 is, other than some sort of hash function, and have no idea how to check it.
It seems there are utilities to check it. Based on what the WinMD5 utility I downloaded tells me, it seems that the file is fine. I'll try to load it and see what happens.
EDIT: OK, I think I need to just do a factory reset and forget about it.
I downloaded ADB and fastboot, put it on my desktop. There are two nested folders inside the main folder. I put the recovery file into the Android folder which has the fastboot application. Opened a cmd window from within that folder and typed 'fastboot devices'. Nothing happened. It just came back to the same command prompt. The serial # wasn't returned. Nada.
EDIT II: I booted into bootloader manually and tried 'fastboot devices' again from the command prompt. It worked this time, returning the serial #. Next I tried to flash the recovery file and got the following message - "error: cannot load 'openrecovery-twrp-2.6.0.0-evita' : Unknown error. I decided to try the AIO kit and see what happened. Selected Your Own Recovery and started the process. The window opened to select the .img file and no file was showing that had that file extension. I think the problem is that the downloaded file is being seen by my computer as a zip file. Can I simply change the file extension to .img?

That's a bit odd, it shouldn't download as a zip, it should be a file with the ".img" extension. Did you download it from the link I posted? Are you able to check the extension type in file properties?
Also I noticed you had a command return saying 'openrecovery-twrp-2.6.0.0-evita', did you make sure you put the ".img" extension on the end of your fastboot command?
Sent from my Evita

I did include the .img extension. Tried it again now and it worked. I must have made a type when I tried the first time.
So, I have a custom recovery process installed. Now, what ROM would you suggest?
By the way, I do appreciate the help.

I can't really suggest a ROM, as best/favorite ROM threads and questions aren't allowed on XDA. In this case I can probably point you in the right direction though.
The OTG side of things lies within the kernel though, not the ROM itself. The only kernel I can think of that has this support is the Rohan b6 Kernel, which you'll find here.
This means you'll only be able to use 4.1 based ROMs from this section though. The reason for this is because aosp kernels can only be used with aosp ROMs. If you try to use this kernel in conjunction with a sense based ROM, or an aosp ROM from a different android version (4.0, 4.2, 4.3) it won't work.
Keeping all that in mind, there are some great 4.1 aosp ROMs in that section. Development has moved into 4.2 and above but you'll still find the 4.1 ROMs there. Just make sure to look at the android version in the title and features of the ROM.
Flashing a custom kernel is an extra step in the install process too. Do the wipe in recovery like I described earlier, then install the ROM, then install the kernel. Instead of extracting the boot.img from the ROM zip, extract it from the kernel zip and use the same method I outlined before to flash it in fastboot.

Sent from my Evita

Well, we're getting there, I think.
I've got the file loaded onto the phone. The filename is rom.zip. I've done the wipe and then from the Install menu I selected the rom.zip file and swiped to start. Got an error message saying 'unable to open zip file'.
Tried a different ROM and it worked.

Which ROM did you end up going for?
Sent from my Evita

Started with Evervolv. That's the one that didn't work. Then went to Cyanogen. It's still booting for the first time so still hoping it all worked.

Did you flash the boot.img via fastboot afterwards?
Sent from my Evita

Yep. The one from the new kernel.
Did a wipe, advanced wipe, installed the ROM, installed GAAPS, installed the kernel, flashed the boot.img from the kernel zip file.
It's at the Cyanogen spinning wheel. My understanding is that it can take a while on the first boot?
If it sits here for much longer, I'll do it again, wipe and reinstall.

It can take a while, not normally longer than five minutes though.

[SOLVED] Nexus 5 stuck in boot loop animation (Lollipop) , partially working with 4.4

I have a Nexus 5 32GB that's about 14 month old. Was running Lollipop 5.1 which was installed through OTA updates (4.44 >5.0 >5.01>5.1). The device is stock and unrooted.
One day, after powering the device up, it went into the boot screen and never managed to finsih the boot (for hours).
After reading extensively on this and other forums , here are the steps I tired , without success:
1. Go to bootloader and press Start
2.Go to bootloader , erase cache
3.Go to bootloader erase user data (factory reset).
I then tried to flash the factory image back. I tried all Lollipop versions from the google developers page of factory images.
starting with 5.1.0 (LMY47I) and going down. All flashing was completed successfully, but the problem remains.
Then I tried 4.4.4 (KTU84P) and the device finally booted up, but it was crippled: Most times It only sees a storage of 16GB , the phone does not recognize any cellular carriers, google play crashes, camera crashes, gallery crashes. An error states that "no external memory is available". Basically it was useless.
I took the phone to an LG lab. They said I need to replace the motherboard. Costs about 200$ !!
I was about to get a new phone , but decided to try one more google search for a fix.
This guide is for any poor soul in the same state.
This issue can be solved without replacing the motherboard for 200$.
The problem in my case was that the /persist partition was degraded, and could not mount.
I found out by trying to follow this guide: http://android.stackexchange.com/qu...dots-lollipop-screen-after-hard-factory-reset
I got as far as activating ADB Sideload when I got the error "cannot mount /persist".
This is a software problem.
Her's how to fix it (It's a long and detailed guide - but worth the result):
First, you must enable USB debugging mode , if it was not enabled (if it is enabled you can skip the first step of this guide) . The way to do that is to flash a stock image that will load, even if not fully working. In my case I could flash version 4.4x and get the phone to load. I am not aware of any other way to enable USB debugging, other than from within a working OS. If someone knows a way - please post it.
The easiest way I found to flash my phone is using Julian OS' script. You can download the stock image5.0 and 5.01 with the script from here:
https://www.androidfilehost.com/?w=files&flid=22367
You will need to adapt the 4.4x firmware to have the script flash it, but it's very easy, just a couple of files to rename.
When you open Julian's zip file you will see that he uses a script that flashes the firmware's images one by one. What I did was download the stock images from Google https://developers.google.com/android/nexus/images , used winrar to extracrt all the files from the .tgz file to a folder, then unzip the only zip file there (image-hammerhead-xxxxx.zip) which contains 5 img files. I then renamed the radio-hammerhead-xxxxx.img to radio.img and bootloader-hammerhead-xxxx.img to bootloader.img. Now all the file names comply with Julian's script. From Julian's archive copy the files "From Bootloader.bat" and "fastboot.exe" to the folder where all the images you just renamed are.
Put the phone in bootloader mode (turn the phone off, press the Vol- and the power buttons). Once the the phone is in bootloader mode, connect it to the PC and run "From Bootloader.bat" and follow the onscreen instructions. In about 2 minutes, your phone will be flashed.
Turn the phone on, it should load the OS. Disregard all the error messages, and don't bother setting the phone up. If you skip wifi, and don't have a sim in the phone you can finish the basic setup quickly.
Next you need to get developer tools activated: Settings>about phone>Build number. Tap 7 times on the build number and this will unlock Developer tools. Go back to settings and the new Developer Tools and enable usb debugging. Approve any popups.
*** I am not aware of how to enable usb debugging if you cannot go into the settings. If non of the stock images loads for you, search for a way to get usb debugging working , or else you cannot continue. You need this for ADB to connect to the phone.****
Next, you need to have ADB on your PC, and it should be able to reach your phone. If you already have - then skip to the next step. If you don't - then here is how to get the latest version:
Go here and download the installer https://developer.android.com/sdk/index.html#Other
Install the file and when it's done run SDK manager. Choose only the first 2 tools (Android sdk tools and Platform tools), this will install the latest adb and fastboot tools. To make sure all is installed open a command prompt (Click Start, type cmd in the search and run cmd.exe) and type adb. You should see all the adb possible commands typed. Now you can test if your phone can be reached by adb: connect your phone (remember usb debugging must be on!) and type: adb devices. After a few seconds you should see something like this:
List of devices attached
024703f599cc8feb device
If you get this, it means you have usb debugging enabled and a proper usb driver installed and you can go to the next step . If there is no device in the list you need to install/update the USB driver:
You have to make sure that when you connect your phone with USB debugging on, you have 2 entries in Winodws Device manager:
Under Portable devices >Nexus 5 , and under Android device> Android composite ADB Interface.
If the second one is missing, ADB will not work and you can't continue. There are 2 ways to fix that :
1. You can install an Android driver called Universal Naked Driver 0.73 from here: http://forum.xda-developers.com/showthread.php?t=2386956. Unzip the file to a folder.
The author of that guide states you need to uninstall any driver that already exists. This proved tricky because Windows would not uninstall the Nexus 5 driver. I decided to install it on a PC that has no android driver.
When you connect the phone to a windows 7 pc for the first time it will search for a driver. I disconnected the internet and windows installed a generic driver. In device manager I saw Nexus 5 with a yellow triangle. I Right clicked on it > update driver software > Browse my computer for driver software and point to the folder you unzipped the driver. You will get a warning - allow the installation.
2. If that does not work or if you don't have another "virgin" PC try this:
Run SDK Manager, under Extras mark Google USB driver. You don't need anything else marked. Install the driver.
Now connect your phone to the PC in normal mode (not bootloader!) . Open device manager. You should have two entries: Portable devices >Nexus 5 and Android device > Android Composite ADB Interface
If the second one is missing, but the Nexus 5 is properly installed, Right click on the Nexus 5 device >Update driver software > Browse my computer for driver software >Let me pick from a list. Now make sure that "Show compatible Hardware" is ticked . You should now have an entry called "USB composite device". Choose that and let it install. When it's done, if you still have an an Unknown device >Nexus 5 and no Android Composite ADB Interface in device manager, then unplug the phone and reconnect it again . You should now have both devices installed.
If by chance this does not work, and you have a Nexus 5 with a yellow error , right click it>update software driver> Browse my computer.> and point it to the Universal Naked Driver folder or the SDK>Extras>Google USB driver folder and it should update so both devices appear (Nexus 5 and ADB).
Once adb can see your pohne go here, to read bitdomo's guide to fix the broken persist partition.
http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
There are some prerequisites to getting this to work:
The first one is that the phone can be reached by ADB, this is why you needed the usb debugging mode to be turned on, and the proper usb driver installed.
Second, you need to install a custom recovery image. Don't worry, you will overwrite it later. The one I used is TWRP. Get the latest version from here:
http://techerrata.com/browse/twrp2/hammerhead
To install I recommend you copy Fastboot.exe and the TWRP file to an empty folder on your PC . Rename the TWRP file to "recovery.img". Open a command prompt in the folder (see here if you don't know how http://www.techsupportalert.com/content/how-open-windows-command-prompt-any-folder.htm) , in the black window type: fastboot flash recovery recovery.img and hit Enter. Wait a few seconds and it will finish.
Last, you need to root your device. There are many ways to do this. I did this very simply by downloading CF-Auto-Root from https://autoroot.chainfire.eu/ The file you need is this: https://download.chainfire.eu/363/CF-Root/CF-Auto-Root/CF-Auto-Root-hammerhead-hammerhead-nexus5.zip . Unzip it, put your phone in bootloader, run root-windows.bat.
Now you are prepaired... Follow the guide by bitdomo . Open a command prompt , and run the 2 commands bitdomo wrote. You will get a series of questions , type y followed by Enter until it's all done.
SInce you are still in bootloader mode, and a big START is at the top of the screen, click the power button to reboot. Now your oS 4.4x should load properly. Make sure everything is working.
I did not follow the steps for the wifi and BT fix , because they worked fine (and still do 4 months later) , but you can go ahead and do that too.
Now you can flash to the latest firmware 5.10 - download the file from the developer site I gave before, use Jason Os's script to flash the image, and lock the device. Done! Boot up the device and make sure it recognizes the right amount of RAM on your phone (16 or 32GB). If it does, then all is well .
When I first booted the device , I saw that it only recognized 16GB instead of 32GB. To solve this install TWRP again, go to Wipe>Format data . Then reboot the device and make sure you have 32GB.
If you like the stock recovery instead of TWRP you can use Fastboot to flash the original recovery.img.
Now you have a working Nexus 5 , v5.10.
Thanks to LyricWulf and bitdomo for their life saving guides. I hope this helps others in the same spot, and saves them 200$ .

Not sure what your problem is, but if you are stuck at the boot screen (with the colored dots spinning) you might have the smae problem I describe. You can try to go to bootloader and wipe the cache, if that does not help and you don't mind a wiping all your data do a factory reset. , Go to recovery mode (third option in bootloader), then press the powr and vol up buttons together several times until you get into recovery. Then choose what you want to wipe.
If that does not restore your phone you need to follow my guide. Probably your persist partion is degraded and needs to be fixed. If you follow my guide you will find out what your problem is.
Good luck

Or just read the stickies.

I had the same problem, and for me, simple NAND restore from TWRP recovery solved this issue. I recently made this NAND backup for no reason and it happens to be a very good move. Cheers

Thank you so much for this! You saved my phone!

Where is the backup saved?

https://www.androidfilehost.com/?w=files&flid=22367
You will need to adapt the 4.4x firmware to have the script flash it, but it's very easy, just a couple of files to rename.
When you open Julian's zip file you will see that he uses a script that flashes the firmware's images one by one. What I did was download the stock images from Google https://developers.google.com/android/nexus/images , used winrar to extracrt all the files from the .tgz file to a folder, then unzip the only zip file there (image-hammerhead-xxxxx.zip) which contains 5 img files. I then renamed the radio-hammerhead-xxxxx.img to radio.img and bootloader-hammerhead-xxxx.img to bootloader.img. Now all the file names comply with Julian's script. From Julian's archive copy the files "From Bootloader.bat" and "fastboot.exe" to the folder where all the images you just renamed are.
Put the phone in bootloader mode (turn the phone off, press the Vol- and the power buttons). Once the the phone is in bootloader mode, connect it to the PC and run "From Bootloader.bat" and follow the onscreen instructions. In about 2 minutes, your phone will be flashed.
Turn the phone on, if you are lucky it will load the OS. Disregard all the error messages, and don't bother setting the phone up. If you skip wifi, and don't have a sim in the phone you can finish the basic setup quickly.
Next you need to get developer tools activated: Settings>about phone>Build number. Tap 7 times on the build number and this will unlock Developer tools. Go back to settings and the new developer tools and enable usb debugging. Approve any popups.
I am not aware of how to enable usb debugging if you cannot go into the settings. If non of the stock images loads for you, search for a way to get usb debugging working , or else you cannot continue. You need this for ADB to connect to the phone.
Once this is done , boot the phone into debugging mode.
Read the guide here http://android.stackexchange.com/qu...dots-lollipop-screen-after-hard-factory-reset
I got as far as activating ADB Sideload when I got the error "cannot mount /persist". I then understood what the problem was. If you get the same error - you are in luck!
Then go here, to learn how to fix the broken persist partition.
http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
There are some prerequisites to getting this to work.
The first one is that the phone can be reached by ADB, this is why you needed the usb debugging mode.
Second, you need to install a custom recover image. Don't worry, you will overwrite it later. The one I used is TWRP. Get the latest version from here:
http://techerrata.com/browse/twrp2/hammerhead
To install I recommend you copy Fastboot.exe and the TWRP file to an empty folder on your PC . Rename the TWRP file to "recovery.img". Open a command prompt in the folder (see here if you don't know how http://www.techsupportalert.com/content/how-open-windows-command-prompt-any-folder.htm) , in the black window type: fastboot flash recovery recovery.img and hit Enter. Wait a few seconds and it will finish.
Third, you need to install an Android driver called Universal Naked Driver 0.73 from here: http://forum.xda-developers.com/showthread.php?t=2386956. Unzip the file to a folder.
Since the author of that guide states you need to uninstall any driver that already exists, I decided to install it on a PC that has no android driver. When you connect the phone to a windows 7 pc for the first time it will search for a driver. I disconnected the internet and windows installed a generic driver. In device manager I saw Nexus 5 with a yellow triangle. I Right clicked on it > update driver software > Browse my computer for driver software and point to the folder you unzipped the driver. You will get a warning - allow the installation.
Last, you need to root your device. (I think this can also be done from within TWRP , but I am not sure how...) I did this very simply by downloading CF-Auto-Root from https://autoroot.chainfire.eu/ The file you need is this: https://download.chainfire.eu/363/CF-Root/CF-Auto-Root/CF-Auto-Root-hammerhead-hammerhead-nexus5.zip . Unzip it, put your phone in bootloader, run root-windows.bat.
Now you are prepaired... Follow the guide by bitdomo . Open a command prompt where adb.exe is located , and run the 2 commands bitdomo wrote. You will get a series of questions , type y followed by Enter until it's all done.
SInce you are still in bootloader mode, and a big START is at the top of the screen, click the power button to reboot. Now your oS 4.4x should load properly. Make sure everything is working.
Now you can flash to the latest firmware 5.10 - download the file from the developer site I gave before, use Jason Os's script to flash the image, and lock the device.
When I first booted the device , I saw that it only recognized 16GB instead of 32GB. To solve this install TWRP again, go to Wipe>Format data . Then reboot the device and make sure you have 32GB.
If you like the stock recovery instead of TWRP you can use Fastboot to flash the original recovery.img.
Now you have a working Nexus 5 , v5.10.
Thanks to LyricWulf and bitdomo for their life saving guides. I hope this helps others in the same spot, and saves them 200$ .
Addendum: According to bitdomo, installing a custom recovery like TWRP enables USB debugging by default even if the phone does not boot. I have not tried this myself, but this means you can foergo installing os 4.4x , and go straight to ADB and run the command that fixes the persist partition.
Go ahead and try it. It will save you a lot of time!

My N5 has exact problem as yours even same errors of camera and playstorw crashing when i loaded older android version.. now im positive your instructions will help me but im having some trouble with your steps i do not know how to type comnands with ADB .. im truly novice and dont want to damage the phone more could you simplify the steps or make a video please? Thank you

Sorry, I can't make it any simpler than that. I can't make a video now because my phone is fixed. Adb is very simple, it's like an old DOS window where you type the text. I would follow Bitdomo's advice and start by installing TWRP. This will get you USB debugging, and you can run ADB and follow his instructions to fix the persist partition.

[Tutorial | In-Depth] Huawei G750-U10 from Android 4.2 to 4.4.2 (+ personal exp)

Hello Everyone. This is my first post on XDA-Developers, and I want to share my experience on how I transferred my Huawei G750-U10 to Android 4.4.2. For the people not interested in my experience, and are only here for the explanation, scroll down to the tutorial part.
Story part (my experience)
First off, I did some research on how to root the phone, because you will need a rooted phone to install other firmware and custom ROMS. Rooting is essentially unlocking an account on your phone that has access to all the files and programs so that you can have more control over your phone (it is normally disabled for security reasons). Rooting the phone was easy. I used a program called RootGenius, which is just a 1 click-root program. Very handy and easy. After this, the hard part started.
Fyi, the only reason that I started this project is because I wanted to play Pokémon GO w/o buying a new device
From this step I did a full backup of my current ROM and NVRAM and wrote down my IMEI numbers (the G750 has 2 IMEI numbers because it has 2 SIM-Card slots). These numbers are unique for your phone and are used for calling and sending SMS messages. So make sure you write them down (in my phone they were also written down under the battery). The program I used to backup the NVRAM and the IMEI numbers is MTKDroidTools.
After this step, I tried unlocking my bootloader. But it was very stubborn (I was using the latest firmware from Huawei, B119) and I tried doing this with fastboot. Which failed every single time and gave a 0x7000 error when I tried to unlock the bootloader. But I have to say that my bootloader was acting weird from the start anyway. Whenever I used the command:
Code:
fastboot oem device-info
It always showed that the bootloader was unlocked, eventhough after I locked it using the command:
Code:
fastboot oem lock
Which is weird. So I will just include a tutorial on how to unlock the bootloader just in case yours works normal.
So, after realising that my bootloader was not working correctly, and I could not install any recovery mod like CWM or TWRP (or any custom ROM for that matter), I found out that I needed to flash to the chip directly. This was also a huge challange, since i've never done this before and I actually did not know what I was doing. I've changed ROMS on phones a couple of times before, but that always was with a unlocked bootloader and so via the "normal" recovery system way.
For this part, I used XDA user: jacktackles' post a lot. He had some handy information about flashing to the chipset immediately and on what files to use. Since my B119 firmware was locked, I first wanted firmware with an unlocked bootloader. So I flashed some Chinese G750 firmware, that changed my device from a G750-U10 to a G750-T00. The flashing process was not flawless at all, and was the part that took me the most time (10+ hours). This all because I forgot to untick 1 simple box... Oh well, I guess that is how it works (at least I got it to work ). So, after flashing this Chinese firmware, the hardest part was done. And I had access to TWRP Recovery. With this I installed the custom ROM that I wanted, and that is where my adventure ended.
So, to summarize: It is not easy, and not beginner friendly. That is why I wanted to make this post: To make it easier for you guys to do the same and get to catch YOUR Pokémon! (Or just to upgrade to 4.4.2). So let's now go to the tutorial part!
Tutorial part
I did this with a Windows 10 64-bit computer, although I would recommend using Windows 7. You will also need a usb-cable to connect your phone to your computer. Make sure that everytime you install a new ROM that you re-enable USB-debugging. You do this by going to your phone options > About Phone > Click "build number" 7 times > Go back to options > Developers options and tick the USB-Debugging tickbox.
Sorry for not uploading screenshots, but XDA prevents me from using any outside links because I'm a new user (so i'll try to be as precise as possible). This means that also any downloadable files should be retrieved from jacktackles' post (again big thanks to him!). His forum post can be found here: http://forum.xda-developers.com/android/general/huawei-g750-u10-honor-3x-kitkat-4-4-2-t3038166.
So, go to his post and download the VCOM drivers, MKT Droid Tools, B113 4.2.2 base with unlocked bootloader, Root Genius, and this ROM from another XDA-Developer: http://forum.xda-developers.com/showthread.php?p=62356379#post62356379 (Thanks a lot mate! Awesome upload). The Gaaps link is not needed with my method, and the last link is down. So you will need to get a replacement ROM for that. I used one from NeedRom. Just go to their site, and search for G750-U10 and download a ROM that you want (which is Android 4.4.2 of course). Or download another rom from any other site. The one I used is called: G750-U10 KitKat which was listed on the site on: 07/22/2015 11:35 pm. But you can also choose to download another ROM.
So to sum up, we got 3 ROMS:
1. The Chinese Firmware downgrade to B113
(FILENAME: G750-U10 V100R001C00B113CUSTC432D001_Firmware_Slovakia_Austria_Lithuania_Czech Republic_Latvia_Estonia_Greece_05021NHU)
2. The ROM from pavel22 to change the device to G750-T00
(FILENAME: G750-T00_mod8_265_FlashTool)
3. The ROM that we finally are after
(FILENAME: Huawei G750 U10 Kit Kat 4.9.16)
(In my case of course, not if you downloaded another "final" ROM)
Okay, so after all the files are downloaded and extracted (except for the 3rd ROM), we can start!
1. Rooting
This step is very simple and quick. Plug in your phone to your PC and open Root Genius. Click the big button and your phone should be rooted. If it gives an error, just try again and again until it works. After this restart your phone, and a new app "RootKing" should be installed. If not, the phone is not rooted.
2. MTK Droid Tools (backing up NVRam & IMEI)
Extract MTK Droid Tools from it's ZIP file, and place it in a folder. Now extract the VCOM drivers and install them. These drivers make MTK Droid Tools recognize your device. After installing the drivers, open up the .exe file from MTK and make sure it recognizes your device. If it does not, reboot your PC and try again. After your device is recognized, install the "adbd insecure" app on your device, from the playstore (or download it somewhere else if you do not want to pay). But trust me, it is worth the money. Once adbd is installed, tick both boxes on the app, so that we can connect to your phone with MTK. If done correctly, MTK Droid Tools should now be able to get full access to your device, and a green box will appear in the left bottom of the program.
Now, backup your NVRam and IMEI. You do this by clicking on the "IMEI/NVRAM" button, and clicking backup. To be safe and for ease of access, write down your IMEI's on a paper or notepad file. Now the real fun starts!
2.5 Unlocking the bootloader (you might not have to do this)
Only do this step if you get a BROM error with code 6045 when trying to flash any roms. Here is how you unlock the bootloader:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
3. Flashing the Chinese Firmware
In the Chinese firmware folder, there will be 4 sub-folders: SD_Upgrade, Update Tool, USB_DRV, USB_Upgrade.
0. Delete the SD_Upgrade folder (Not needed).
1. Go to USB_DRV and install the .exe file in the: "Driver For servers 2012-11-27" rar file.
2. After this open the Update Tool folder and extract files.
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file.
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
4. Flashing the: "G750-U10 to G750-T00" Firmware
This will be almost the same as part 3.
Extract the "G750-T00_mod8_265_FlashTool" rar file, and:
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file (make sure that you select the scatter file from the new rar file, and that you are not using the same one as before).
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
5. Restoring your NVRam and IMEI
You might need to root your device again, check if need be, by searching for an app called SuperSU or RootKing. If they are not present, root the device again with Root Genius.
You will need to re-install the "adbd" app on your new ROM. If there is no Play Store present, search for a Play Store APK on Google. Once, installed check the 2 tickboxes and re-open MTK Droid Tools.
Click on the "IMEI/NVRAM" button restore your backed-up NVRAM and retype you IMEI codes. Once the restores are done, restart the phone and check if you can call someone. If it works, good job! You can now progress to the very last step! If not, check if you entered the IMEI correct. You probably made a Typo.
6. Installing final ROM
Now that you have installed pavel22's ROM, you have access to a recovery system. So copy the whole 3rd zip file to the root folder of you device. Turn off your device, and turn it on again but this time while holding both volume buttons and the power button until TWRP opens. Click on install, search your zip file and swipe right. When it finishes, do a factory reset from TWRP and then reboot the system normally. You should now have a fully working G750-U10 with Android 4.4.2. Congratulations!
This was my tutorial and personal experience with converting my G750-U10 to Android 4.4.2. It has been a wild ride, and i've reached points that I wanted to throw my device against the wall. I'm now very happy with my (feeling like) new device. I can now finally catch 'em all and become the best PokéMaster ever!
~ NeusAap.

Thank you for the tutorial. I know nothing about flashing.
However, I could follow the instruction until 4. Flashing the: "G750-U10 to G750-T00" Firmware.
The problem is that after I had clicked the "Download" button, and connected my device, the error popped up BROM ERROR : S_SECURITY_SECURE_USB_DL_IMAGE_SIGN_HEADER_NOT_FOUND (6045).
Could you please help? Thank you.

That error means that your bootloader must be locked. For me, it was acting weird. They way you want to (try) to unlock the bootloader is as follows:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
If your bootloader is now unlocked, you should try to flash again. My phone gave an error at the step 9, but I still followed these 9 steps. So the error I got could also have been a visual programming error, or bug.
I hope this helps! Keep me up to date

Same error. I tried several times with "fastboot oem unlock" but it didn't work: err 0x7000. I could't find anything helpful on the internet.
The odd thing is when i typed "fastboot getinfo-bootloader" I got "(bootloader) unlocked".
I just wanted to be a pokemon trainer too

That was the excact same error I was getting. Also the same deal with the oem get-bootinfo thingy. Are you sure that while flashing you have unticked the "preloader" and the "usrdata" sectors? That is what did it for me honestly

Alright, then skip step 3 and go to step 4. I might have screwed up the step orders (It's hard to remember in what order I did all the steps ) if that works, i'll change the OP. I'm dorry if thats the case.

You mean flashing the G750-T00 fw and then the chinese one? So I have to reinstall the original fw? Cause currently I'm running the chinese

Yes, flash the g750-t00 one, and then the rom that you want if that worked. I think that I might have skipped that whole firmware downgrage rom

Thank you for answering
I tried what you had told me to do, but when I typed "fastboot oem unlock", the phone told me to use Volume Up/Down button. I used "Volume Up" button to unlock bootloader but it failed - err 0x7000 same as Iroh96, I guess. So I typed "fastboot getinfo-bootloader"; however, I got "waiting for device" instead of "(bootloader) unlocked". Then, I tried step 4 but it was still an error 6045. I don't know what to do next.
Why is it so hard to be a pokemon trainer?

hi, i couldn't download the:
"Rooted with twrp recovery inbuild base rom"
because the link is not available.
is this really necessary?
if yes, can you give me another link to download it?
i wanna start follow the steps but first i need all the downloads

Inquiries
I already read and downloaded all files which included in jacktackles thread.. I even read the whole posts
My point of view is, im kinda a noob to root business and afraid to end up by destroying my device especially when I contacted an Egyptian -who had already converted his phone- and he didn't recommend to do this.. so please bare with me.
*first of all is the deal link for "Rooted with twrp recovery inbuild base rom" is this really necessary?
*2nd point is my phones build, its B116. Can I proceed converting my phone or it won't work?
Thanks in advance

FOR THOSE WHO ARE HAVING TROUBLE UNLOCKING THE BOOTLOADER:
I found this post from Pavel22
http://forum.xda-developers.com/showpost.php?p=55497054&postcount=1768
Good luck! I successfully converted my Huawei G750-U10 to G750-T00. Now, I'm on Kitkat 4.4.2. Thanks for this in-depth tutorial, btw. Was really a great help.

Just go to their site, and search for G750-U10 and download a ROM that you want (which is Android 4.4.2 of course). Or download another rom from any other site. The one I used is called: G750-U10 KitKat which was listed on the site on: 07/22/2015 11:35 pm. But you can also choose to download another ROM.
So to sum up, we got 3 ROMS:
1. The Chinese Firmware downgrade to B113
(FILENAME: G750-U10 V100R001C00B113CUSTC432D001_Firmware_Slovakia_Austria_Lithuania_Czech Republic_Latvia_Estonia_Greece_05021NHU)
2. The ROM from pavel22 to change the device to G750-T00
(FILENAME: G750-T00_mod8_265_FlashTool)
3. The ROM that we finally are after
(FILENAME: Huawei G750 U10 Kit Kat 4.9.16)
(In my case of course, not if you downloaded another "final" ROM)
Okay, so after all the files are downloaded and extracted (except for the 3rd ROM), we can start!
1. Rooting
This step is very simple and quick. Plug in your phone to your PC and open Root Genius. Click the big button and your phone should be rooted. If it gives an error, just try again and again until it works. After this restart your phone, and a new app "RootKing" should be installed. If not, the phone is not rooted.
2. MTK Droid Tools (backing up NVRam & IMEI)
Extract MTK Droid Tools from it's ZIP file, and place it in a folder. Now extract the VCOM drivers and install them. These drivers make MTK Droid Tools recognize your device. After installing the drivers, open up the .exe file from MTK and make sure it recognizes your device. If it does not, reboot your PC and try again. After your device is recognized, install the "adbd insecure" app on your device, from the playstore (or download it somewhere else if you do not want to pay). But trust me, it is worth the money. Once adbd is installed, tick both boxes on the app, so that we can connect to your phone with MTK. If done correctly, MTK Droid Tools should now be able to get full access to your device, and a green box will appear in the left bottom of the program.
Now, backup your NVRam and IMEI. You do this by clicking on the "IMEI/NVRAM" button, and clicking backup. To be safe and for ease of access, write down your IMEI's on a paper or notepad file. Now the real fun starts!
2.5 Unlocking the bootloader (you might not have to do this)
Only do this step if you get a BROM error with code 6045 when trying to flash any roms. Here is how you unlock the bootloader:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
3. Flashing the Chinese Firmware
In the Chinese firmware folder, there will be 4 sub-folders: SD_Upgrade, Update Tool, USB_DRV, USB_Upgrade.
0. Delete the SD_Upgrade folder (Not needed).
1. Go to USB_DRV and install the .exe file in the: "Driver For servers 2012-11-27" rar file.
2. After this open the Update Tool folder and extract files.
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file.
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
4. Flashing the: "G750-U10 to G750-T00" Firmware
This will be almost the same as part 3.
Extract the "G750-T00_mod8_265_FlashTool" rar file, and:
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file (make sure that you select the scatter file from the new rar file, and that you are not using the same one as before).
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
5. Restoring your NVRam and IMEI
You might need to root your device again, check if need be, by searching for an app called SuperSU or RootKing. If they are not present, root the device again with Root Genius.
You will need to re-install the "adbd" app on your new ROM. If there is no Play Store present, search for a Play Store APK on Google. Once, installed check the 2 tickboxes and re-open MTK Droid Tools.
Click on the "IMEI/NVRAM" button restore your backed-up NVRAM and retype you IMEI codes. Once the restores are done, restart the phone and check if you can call someone. If it works, good job! You can now progress to the very last step! If not, check if you entered the IMEI correct. You probably made a Typo.
6. Installing final ROM
Now that you have installed pavel22's ROM, you have access to a recovery system. So copy the whole 3rd zip file to the root folder of you device. Turn off your device, and turn it on again but this time while holding both volume buttons and the power button until TWRP opens. Click on install, search your zip file and swipe right. When it finishes, do a factory reset from TWRP and then reboot the system normally. You should now have a fully working G750-U10 with Android 4.4.2. Congratulations!
This was my tutorial and personal experience with converting my G750-U10 to Android 4.4.2. It has been a wild ride, and i've reached points that I wanted to throw my device against the wall. I'm now very happy with my (feeling like) new device. I can now finally catch 'em all and become the best PokéMaster ever!

I can't download the KitKat rom from needrom.is there any other link?????

Hi mates! I'm stuck in the bootloader unlock step; it keeps showing the 0x7000 error and it doesn't let me flash anything with the SP Flash Tool (guess it's because of the 0x7000 error). I tried to follow the Pavel22 guide posted up there... i can flash the rework-secro succesfully, but i get the 4008 error when flashing the whole rom. Can someone help me? Thanks!!

Lg V20 H910 (up to 20h) (root, twrp, and more!) Noob guide!

i am making this post because i have an lg v20 running 20h. there was no root guides available, so i decided to root mine using an older guide. it succeeded, but was very hard and time consuming. Being a noob at the time, i was also extremely nervous that i could possibly brick my phone or screw something up. i didn't, and no part of this should brick yours either. ***However - if you do somehow break your device in any way, that is on you. by completing these steps, you assume full responsibility. now that we have that out of the way, lets continue. at the end of this guide, you should have a rooted device with your choice of os (7 or 8 - or even a custom rom if you choose!). you should also have twrp. this guide would not have been possible without users runningnak3d and clsA
**** Also, during this Proccess, Your Phone WILL be wiped clean!!! don't forget to back up photos, videos, etc...*****
don't download any other files than from this guide.
1. download these files (required) https://lg-firmwares.com/downloads-file/4578/H91510e_00_VTR_CA_OP_1205.kdz (for a rootable os that we can flash, - get this also (required) https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222 this program is called lg up and has been patched to work with this phone. you will also need this. https://androidfilehost.com/?fid=1322778262903990218. these are the root files and need to be all in the same folder as where lg up is installed. you will also need to have access to fastboot and need to have adb installed. that is pretty easy, give it a google search if you still need help.
if you are running 32 bit, get this https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
this is the OS. get nougat, which has like three less steps (you can't upgrade to oreo on this os once rooted) or scroll down and get the oreo file. nougat (really old version) https://drive.google.com/file/d/1S82HVNt2rAtXgBY499IBJnoCVFnpCf_X/view
Oreo - get this first file, and the ones under it. https://www.androidfilehost.com/?fid=1322778262904015326
***https://androidfilehost.com/?w=files&flid=283977*** You have to have this file if getting oreo. if you chose nougat, then don't get this.
2. Now that you have everything downloaded and installed, put your phone into download mode. (power it off, hold the volume down button and plug in a usb c cable attached to your pc. don't stop holding volume down until you see download mode.)
3. once it is in download mode, open up lg up. select your device, (it should be in standby mode, according to lg up) and click dump (this is a total backup of the phone, you are lucky you know this right now, I didn't when i rooted mine) . it will bring up a file explorer, select where you want it to save to. (I chose my desktop). once you have a folder selected., it will bring up a bunch of options for partitions. click select all and uncheck user data. ****Make SURE that you don't unplug your phone during any part of this process or any other process in this guide, it will permanently brick it. ***** ow that you have selected everything but userdata, click start.
4. once that finishes, you will have made a full backup of your phone in case something goes wrong.
then click the partition DL button and select the h915 v10e kdz file (the file that i said was the rootable os we can flash) (the first file you downloaded). make sure bin file stays checked. then click start. once that finishes, your phone should automatically reboot into an old nougat operating system. then go to settings, enable developer options, and turn on usb debugging. that is easy, if you can't figure it out, google is your friend. now you should have no cellular signal. this is not the permanent ROM.
5. go to the play store and download terminal emulator for android. (once usb debugging has been enabled
then go ahead and go to the folder where you extracted the root files/package. hold shift and right click to open a command windows there or powershell, whatever your pc says. open 2 of those windows. then, in the first one, type, adb logcat -s dirtysanta
****don't close this window.*****
then in the other window, type STEP1.BAT
*****don't close this window.***** It may take a minute, but after a while it will let you type again. once you can, type run-as con
chmod 0777 /storage/emulated/0/*
6. then, pull up the window you used the logcat command in. leave it there so you can watch it
then, on your phone, go to the terminal emulator and type applypatch /system/bin/atd /storage/emulated/0/dirtysanta
once you do that, glance at the logcat window. once it says to run step 2, go to the window where you typed step1.bat. type STEP2.BAT
at this point, your phone should go ahead and reboot and say fastboot mode up at the top. now, go to your window where you typed all the .bats and type STEP3.BAT. wait until your phone reboots and you will see a screen saying that you can;'t use your phone. this is bogus, just ignore it and wait like 10-15 seconds for it to get past that screen. then it will boot that android and you should get a green screen.
Now, quickly, pull the battery from your phone. leave it out for a little while while we prepare the next steps.
If you want oreo, scroll to where it says OREO in capital letters. if you want nougat, scroll to where it says NOUGAT.
NOUGAT
use the file that you downloaded if you selected nougat - it should be a zip. it will be called h910-10r. DO NOT, I REPEAT, DO NOT UNZIP THE FILE. place it on a pre formatted micro sd card. then, place the battery and sd card back in your phone. also, unplug the phone. then, hold down the volume down key and hold hold the power key. once you see the lg logo, release the power key and immediately hold the power key again. then, you should get a screen that asks if you want to reset your phone. use your volume keys to navigate and select yes, then again confirm it. then, after letting it reboot, it should go into twrp. once there, go to wipe\and select format data. then type yes to confirm. then, go back to the main screen and click wipe again. go ahead and click advanced and wipe your dalvik cache. once done, go to home screen and click install. select the select storage option down at the bottom and change to sd card. then find the h910 zip file and install it. then go ahead and reboot your phone, you will have a rooted android 7 rom. you will also have signal. then download supersu from the play store and open it to have root.
OREO
use the file that you downloaded if you selected oreo - it should be a zip. it will be called something along the lines of full stock oreo rooted. DO NOT, I REPEAT, DO NOT UNZIP THE FILE. place it on a pre formatted micro sd card. also, go to your root package folder and find the twrp image file and put that on your sd card. then go get the mk200 zip file and also place that on your sd card. then, place the battery and sd card back in your phone. also, unplug the phone. then, hold down the volume down key and hold hold the power key. once you see the lg logo, release the power key and immediately hold the power key again. then, you should get a screen that asks if you want to reset your phone. use your volume keys to navigate and select yes, then again confirm it. then, after letting it reboot, it should go into twrp. once there, go to wipe\and select format data. then type yes to confirm. then, go back to the main screen and click wipe again. go ahead and click advanced and wipe your dalvik cache. once done, go to home screen and click install. select the select storage option down at the bottom and change to sd card. then find the oreo full rooted zip and install it then, install the mk2000 file. after you have done this, click install image and select the twrp. the reason you need to re flash this is because that oreo file re installs the stock recovery. then install the twrp. now reboot your phone. you will have a rooted android 8 rom. you will also have signal. then download a magisk 6.0 manager apk from chrome browser to have root.
IF this worked and your enjoying root give me a thanks.

This is redundant to the existing h910 root guide, all you did was copy their work and re-post it

Yes, that is why i gave them credit. However, It is more noob friendly and takes the time to explain what they are doing to their own phones as well as give them the option for nougat or oreo, something that none of the other guides have.

Ok, so I did it sucessfully, it's was still very complicated for me as some info is vague for a beginner. But after searching and retrying, and retrying, it worked. but go to runningnak3d post to get more info, and he wanted me to use sd card to root, but that did not work for me.. Your method worked for me. Thanks

your guide is good
+1 for for linking to the missing files from the old guide
+1 for mentioning me and @runningnak3d
you could break up the long paragraphs and bullet style the steps in order so it's easy to follow
theirs a video here of the steps and how the command windows should look > https://www.youtube.com/watch?v=jnRWnSHLGSc
this is where allot get confused in the guide.
I also don't remember you mentioning doing the battery pull after STEP1 when the phone sometimes hangs then run STEP2
I would also change the link to the H915 kdz to the android file host file in case LG changes it.
Their was a guy recently that could not get LGUP working you could make note that you may need the 32 bit VS 2010 > https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
Any how, the guide is OK and the steps are not that bad, after a few tries most anyone can learn it.

alright, thank you so much for the advice! 1. i don't want to switch to bullets because when i was trying runningnak3d's guide, it seemed overwhelming. also people can comment on the step number that they were lost at. 2. i will change the kdz to something else if the file does change. i did in fact mention the battery pull step, if you ever need to find something in a page, hit control and f and then search the page.. i will add the 32 bit file. Thanks!

What a way to rip-off runningnak3d's guide.
I mean, I can understand rewriting it... I did the same. But, just to parse it out for me to follow better.
But your statement "...there was no root guides available..." is just BS.
Below is my guide... for me to do the process.
Creation date on the text file was November 7, 2017. Just over a week after runningnak3d made the original post.
Difference is, I didn't feel the need to post someone else's work, in an attempt to try claiming credit for it, due to nothing more than a "rewrite".

Search in You Tube for "How to Root install TWRP for LG V20 H910 Edition!" from user NewTechBegins. This is very good video tutorial, step by step.

Hello, so nothing happens for me after I enter the code into terminal emulator, what am I missing?

After all these done I'm rebooted to secure start-up where I need to enter password. Tried my 4 digit VIN and didn't work. As suggested earlier in this thread I pulled battery and wipe everything and install Oreo_full_rooted.zip, mk2000, and TWRP 3.3.1-0. It boots up the same to the secure start-up.
I might have done differently in process.
1. H91510e_00_VTR_CA_OP_1205.kdz I downloaded did NOT match MD5 on its download page. Tried twice and it was the same. I went ahead and used it.
2. I ran into "adb server is out of date, killing.." message but was able to download an adbfix and somehow got through
3. STEP1.BAT and the rest of BAT were not accepted in Win10 powershell so I had to enter them by hand and it went smoothly with no error
4. I used twrp 3.3.1-0 as suggested in NewTechBegins' youtube clip
5. Phone boots into scramble messages like shattered warning sign before LG logo appeals. It will eventually enter twrp or secure start-up after some wait. Takes longer than it should, 5 minutes or so.
Wish to stay on Oreo but might try the 10R Rom if I have no other choice.
Please help.
(Secure start-up appeared the first time after step 3 where it was supposedly be a green screen and I can pull battery. It didn't. It went to secure start-up. I pulled battery anyways and rebooted into TWRP, I was asked to enter password again. After a few wrong attempts I was able to bypass it and enter TWRP to proceed with install)
edit: Eventually succeed by not installing TWRP after flashing OREO and MK2000. Rebooted into Secured Start-up again, pull battery and rebooted into FACTORY Recovery and deleted all user data from there. Rebooted and Android setup began.
Note: BE SURE TO FORMAT DATA AGAIN in TWRP after flashing OREO and MK2000 to have a clean start. Would be nice if it was mentioned in this tutorial.

Oreo - get this first file, and the ones under it. https://www.androidfilehost.com/?fid=1322778262904015326
***https://androidfilehost.com/?w=files&flid=283977*** You have to have this file if getting oreo. if you chose nougat, then don't get this.
2. Now that you have everything downloaded and installed, put your phone into download mode. (power it off, hold the volume down button and plug in a usb c cable attached to your pc. don't stop holding volume down until you see download mode.)
3. once it is in download mode, open up lg up. select your device, (it should be in standby mode, according to lg up) and click dump (this is a total backup of the phone, you are lucky you know this right now, I didn't when i rooted mine) . it will bring up a file explorer, select where you want it to save to. (I chose my desktop). once you have a folder selected., it will bring up a bunch of options for partitions. click select all and uncheck user data. ****Make SURE that you don't unplug your phone during any part of this process or any other process in this guide, it will permanently brick it. ***** ow that you have selected everything but userdata, click start.
4. once that finishes, you will have made a full backup of your phone in case something goes wrong.
then click the partition DL button and select the h915 v10e kdz file (the file that i said was the rootable os we can flash) (the first file you downloaded). make sure bin file stays checked. then click start. once that finishes, your phone should automatically reboot into an old nougat operating system. then go to settings, enable developer options, and turn on usb debugging. that is easy, if you can't figure it out, google is your friend. now you should have no cellular signal. this is not the permanent ROM.
5. go to the play store and download terminal emulator for android. (once usb debugging has been enabled
then go ahead and go to the folder where you extracted the root files/package. hold shift and right click to open a command windows there or powershell, whatever your pc says. open 2 of those windows. then, in the first one, type, adb logcat -s dirtysanta
****don't close this window.*****
then in the other window, type STEP1.BAT
*****don't close this window.***** It may take a minute, but after a while it will let you type again. once you can, type run-as con
chmod 0777 /storage/emulated/0/*
6. then, pull up the window you used the logcat command in. leave it there so you can watch it
then, on your phone, go to the terminal emulator and type applypatch /system/bin/atd /storage/emulated/0/dirtysanta
once you do that, glance at the logcat window. once it says to run step 2, go to the window where you typed step1.bat. type STEP2.BAT
at this point, your phone should go ahead and reboot and say fastboot mode up at the top. now, go to your window where you typed all the .bats and type STEP3.BAT. wait until your phone reboots and you will see a screen saying that you can;'t use your phone. this is bogus, just ignore it and wait like 10-15 seconds for it to get past that screen. then it will boot that android and you should get a green screen.
Now, quickly, pull the battery from your phone. leave it out for a little while while we prepare the next steps.
If you want oreo, scroll to where it says OREO in capital letters. if you want nougat, scroll to where it says NOUGAT.
NOUGAT
use the file that you downloaded if you selected nougat - it should be a zip. it will be called h910-10r. DO NOT, I REPEAT, DO NOT UNZIP THE FILE. place it on a pre formatted micro sd card. then, place the battery and sd card back in your phone. also, unplug the phone. then, hold down the volume down key and hold hold the power key. once you see the lg logo, release the power key and immediately hold the power key again. then, you should get a screen that asks if you want to reset your phone. use your volume keys to navigate and select yes, then again confirm it. then, after letting it reboot, it should go into twrp. once there, go to wipe\and select format data. then type yes to confirm. then, go back to the main screen and click wipe again. go ahead and click advanced and wipe your dalvik cache. once done, go to home screen and click install. select the select storage option down at the bottom and change to sd card. then find the h910 zip file and install it. then go ahead and reboot your phone, you will have a rooted android 7 rom. you will also have signal. then download supersu from the play store and open it to have root.
OREO
use the file that you downloaded if you selected oreo - it should be a zip. it will be called something along the lines of full stock oreo rooted. DO NOT, I REPEAT, DO NOT UNZIP THE FILE. place it on a pre formatted micro sd card. also, go to your root package folder and find the twrp image file and put that on your sd card. then go get the mk200 zip file and also place that on your sd card. then, place the battery and sd card back in your phone. also, unplug the phone. then, hold down the volume down key and hold hold the power key. once you see the lg logo, release the power key and immediately hold the power key again. then, you should get a screen that asks if you want to reset your phone. use your volume keys to navigate and select yes, then again confirm it. then, after letting it reboot, it should go into twrp. once there, go to wipe\and select format data. then type yes to confirm. then, go back to the main screen and click wipe again. go ahead and click advanced and wipe your dalvik cache. once done, go to home screen and click install. select the select storage option down at the bottom and change to sd card. then find the oreo full rooted zip and install it then, install the mk2000 file. after you have done this, click install image and select the twrp. the reason you need to re flash this is because that oreo file re installs the stock recovery. then install the twrp. now reboot your phone. you will have a rooted android 8 rom. you will also have signal. then download a magisk 6.0 manager apk from chrome browser to have root.
IF this worked and your enjoying root give me a thanks.

Dont try to install h915 instead just try dirty santa method which will install temporary twrp recovery there install h910 20h pre rooted 8.0 rom and install mk2000 v2.2 kernel and install newer version of twrp and you are good to go
No bricking risk and nothing dont try to do corss flashing of h915 its not that accurate also there is model issue in crossflashing instead doing that do dirsty santa and install h910 20h simple

So how do you use dirty santa method for h910 20h? All the guides I've seen want you to crossflash.

I didn't do crossflashing i first installed twrp throught dirty santa which then you have to open from recovery then there is android 8.0 h910 stock rom pre rooted i used or you can use your custom rom to flash then there is an kernel mk2000 file also to flash from twrp after you installed new rom for fixing errors like static screen and like that thats it also if you flash android 8.0 stock of h910 rom you will get a password during booting process just attempt it wrongs for many trys wrotten on it until you see wipe the data prompt and you will factory reset your phone and its ready to go maybe you will be promoted to twrp so you have to factory reset through wipe option ok and you are good to go one thing do it only on h910 not other model there is 0% chance of hard bricking your phone if you did this and no signal problem
Also to understand more go a see my qna with author of this post in this post obviously ok or if you meed more help reply me i will text you

you have to rewrite the same and exact name with .img in that batch file this ting will not tell any YouTuber or in the website cuz, I find it in curiosity and founded that the TWRP name was wrong so I just renamed it in that batch file and it worked before it it wasn't working also download the exact LG v20 h910 TWRP, not any other model TWRP or you will hard brick it man it feels so bad I one time hard bricked my LG next day I bought the device now I just sold it I change the mobo to LG h910 then I did all that root things and then I sell that phone no I have sony xz3 which is way better and have snapdragon 845 octa-core which is the thing I needed in just 135$ I found that it was japan model refurbished but has all things new and original like poled panel and stuff... well if you need more help just don't reply m on XDA you will not get the answer quickly here my social media account

reply me on that I am online all the time but not online on XDA all the time ok

Installed twrp no problem. Had installation issues (error 7) and edited the file. Tried it again and came up with error 1. Saw someone else on xda say to extract the boot img and mount to the recovery partition successfully. Welp, I guess I wasn't so lucky. I can not get into twrp recovery or any recovery and my v20 (910) boots into the Lg android splash screen. My desktop can not see any adb device but it registers a device being plugged in. What's the verdict, soft or hard bricked? Everything was cleared besides twrp prior to error 7 and 1.

UPDATE:
As i don't have much time, here is the link to our Alcatel tetra and ideal xtra development and support group on telegram.
ALL THE FILES THAT USED TO BE LINKED HERE ARE AVAILABLE AT THE MENTIONED TELEGRAM GROUP

Any questions for myself need go there.
Thanks.

Ok so I am here today to give you a TWRP recovery and A Liniage OS 16 Rom ported from a GSI.
And a quick how to on setting it all up..
DISCLAIMER:
I Am In No WAY responsible for ANYTHING YOU choose to do to your phone.
If you use this and your Dog eats your Cat, Your phone catches fire and burns down your house, or you loose all your game-saves pictures and other files it's NOT MY FAULT.
THIS WILL WIPE YOUR DATA AND FORMAT YOUR PHONE!!!
YOU'VE BEEN WARNED
MY FASTBOOT DOESN"T WORK !
See-This:
Just grab this package I made for @Sloogle_Flugelmann
https://drive.google.com/open?id=1CiGKCPGBJAPvl8R3_24kvdvrQB5V3abI
So requirements are :
#1: Willingness to format your phone and loose all apps and data.{MAKE A BACK-UP}
#2: ADB and Fastboot working on your PC.
#3: The Files I Will Link to or attach .
# Some Time to work on it, and half a Brain
There will be Two methods to accomplish basically the same thing,
Method 1 gives you the long way and it leaves you with the bare basic LOS 16 installed no root no gapps...
on the other hand Method 2 will leave you with LOS 16 and My favorite version of the pixil launcher and stock Gapps included and basically everything working.
METHOD 1-THE LONG ROAD:
STEP 1:
download the package that I will upload for everyone...
STEP 2:
Unlock your bootloader.... there may be multiple ways to do so but for me I enabled usb debugging and OEM unlocking in developers options {if you don't know how to do that you should run far away now !} then I gave the command
Code:
adb reboot bootloader
and this takes you to fastboot mode...
once there issue the following command to unlock your bootloader AND factory-reset the phone
Code:
fastboot oem unlock
then
Code:
fastboot reboot
Now your bootloader is unlocked and your device has been wiped in the process...
so let it boot up then go through the setup wizard and I just skip through everything as we will be wiping it once again in a minute... and just need to get to developer options and re-enable adb...
so do that...
STEP 3: Now that your bootloader is unlocked comes the fun stuff...
Firstly you need an SD-card with at least 4-6 GB free space and before continuing we want to move our LOS-16 System.img to our sd-card so we can install it from TWRP so once that's on the root of Sd-card's storage continue with this guide....
we need to disable DM-Varity to use twrp so we flash a magisk-patched-boot.img
so move the files Patched_boot.img AND twrp_alcatel_5059r_v3-2-3.img to a folder on desktop and open a command prompt /terminal/powershell-window at the file's location.. then issue this command to the phone .
Code:
adb reboot bootloader
and once again we are in fastboot mode.
now we want to use fastboot to replace the stock boot image and stock recovery with our patched boot image and twrp recovery image..
Code:
fastboot flash boot patched_boot.img
then
Code:
fastboot flash recovery twrp_alcatel_5059r_v3-2-3.img
after this we want to reboot to recovery using the hardware keys. because if we don't the stock system will erase our twrp and replace it with stock recovery on boot.
so we do
Code:
fastboot reboot
and soon as you press enter on your keyboard grab the phone and continually hold down the volume-up key and hold the power key .
once you see the alcatel logo and message about unlocked bootloader, you quickly release ONLY the power key for a second then repress and hold it for a count of 5 seconds. then release the power key again and quickly repress it for another 5 seconds and keep doing that for a moment until the screen flashes white then displays the TWRP splash screen.
once we are in twrp it'll ask for the encryption password...
WE DONT HAVE ONE , So just hit Cancel
then it'll ask about system modifications and whatnot,
just swipe to allow modifications.
now we want to head to Wipe > Advanced-Wipe > Format Data
you'll have to type in
Code:
yes
and let it do it's thing.
once done with that we need to reboot to recovery so click the back arrow several times until you are back at twrp's min screen.
head over to Reboot>Recovery
the phone should reboot right back to twrp, you shouldn't see the encryption password screen this time as we formatted DATA.
so now swipe to allow modifications and head back to
Wipe>Advanced-Wipe and check the boxes for system,dalvik-cache,cache,data....
then swipe to wipe them.
then you want to hit the back arrow again till at the main twrp screen again.
Head to Install click on select storage, choose your Sd-card
Click on install zip to change it to install image.
select the LOS image we moved to the Sd-card prieviously,
click on System as the install location.
and finally swipe to flash it.
let it do it's thing.
once completed you will want to click the back arrow again until main twrp screen and reboot to recovery once more....
now once in recovery again you swipe to allow modifications and need to replace the GSI's build.prop file with the one I am including in the zip.
I used adb to accomplish this...
on your PC move the included build.prop file to your working directory{folder your working out of}
and use the terminal/command prompt/powershell to give the following commands
Code:
adb devices
you should see the device identified by serial number and the word recovery next to it
then
Code:
adb shell
you should have a root shell on the device,
Code:
rm -rf /system/build.prop
then
Code:
exit
now your back to pc terminal so type:
Code:
adb push build.prop /system/build.prop
Code:
adb shell
back to root shell
Code:
chmod 0644 /system/build.prop
and then
Code:
reboot now
at this point your phone should reboot and everything was done correctly it'll go past the alcatel logo and bootlock message and then display the LOS 16 boot animation then it'll show a funny looking screen that has an android guy and the message " Please wait while your device is being encrypted"
it'll have a progress counter and when the count-down reacheds zero it'll just hang there....
that's ok, hold the power key until the phone reboots and you should get the los bootanimation followed by the LOS setup wizard start screen.
and you go through the set-up wizard and you'll be in LOS 16 PIE
Now if you want google apps to work there's a few more steps and they will be the same for both method 1 and method 2
if you flash gapps after rebooting from that you'll get a million messages about google play services and google apps crashing ... it's ok
you need to enable usb debugging in the LOS 16 and then sideload the apk ( Device+ID.apk )
Code:
adb sideload "Device+ID.apk"
once installed
open it to get the GSF registration number for your device.
then if you open the play store you'll be greeted by the google DEVICE UNCERTIFIED page...
Don't fret , this is why we fixed the build.prop to reflect our devices orig. build fingerprint...
So scroll down to the bottom of that page and see the last option about Custom Roms
there is a link there... long press that link and choose open in browser
you'll be greeted by the registration page for google...
make sure you are signed into google through your browser...( <---VERY IMPORTANT ) by opening another page to google gmail or the like and signing in with your google account.
then go back to the registration page and hit refresh ...
now it should recognize you by your gmail account in the top right corner i think.
anyhow... go to that ( Device+ID.apk ) that we sideloaded and click on the second set of numbers down the list it should mention (GSF) and choose copy . it'll copy the numbers to your clipboard.
now go back to the browser page from google about registration and paste the copied number into the place next to the (Register) button and then click the register button
it should then list your id converted to decimal on the page...
I did this several times from my PC and got no where but after doing it from the phone it's self a couple minutes later i clicked on one of the error messages about google play services and wholy-krap it finnally let me open google-play-store.
at this point your ready to go....
for an informative article with pictures about this check here:
https://www.xda-developers.com/how-to-fix-device-not-certified-by-google-error/
Now for Method 2
method two involves all the same steps as method 1 up until you get to TWRP... except that instead of moving the LOS16 system.img to your Sdcard before begining you'll want to extract the alcatel-idelXTRA-5059r-LOS16-modded-2019-05-23.zip I've included and move that whole folder to the sdcard...then
go back and read method 1 and once you are booted into twrp for the first time STOP and come back here to Method 2
Now once you get to twrp the first time the first thing to do is click cancel on the encryption screen then swipe to allow modifications on the next screen. then once at the main twrp screen we need to make a back-up that we will likely never use...
so go to Backup>choose storage (micro sd-card) and then make a back-up, Name the back-up My-Backup so that you can easily find it later. to save space and time I'd recommend backing up just the boot partition.
that'll complete quickly...
now for the weird work-around/Dirty-Hack stuff
you should have the contents of alcatel-idelXTRA-5059r-LOS16-modded-2019-05-23.zip a folder called (alcatel-idelXTRA-5059r-LOS16-modded-2019-05-23) on the root of your sd-card's storage...
and we just made our first back-up from twrp of our boot partition.
so from the main twrp screen we go to Advanced>File-manageer>external_sd we should find a folder labeled(TWRP)
inside that should be a folder labled (BACKUPS) and inside that should be yet one more folder with your device's serial or android ID as the label mine is (49NJ6TORP****VRG) your's may read differently. and finally inside That folder you should find the back-up you previously made (My-Backup) if you followed my instructions.
now we need to go back to the root of our sd-card's storage by clicking (up a level) several times and then click on the folder i had you move there earlier (alcatel-idelXTRA-5059r-LOS16-modded-2019-05-23) and once you click it you'll see files inside look down to the right hand corner in twrp
you should see a little blue folder button with a check-mark , Click that button
then it'll show you options....
click (Move) button then click (up a level) it'll look like it took you all the way back to the beginning top level of file manager, now we navigate to where we want the folder Moved to, so click external_sd > TWRP>BACKUPS>49NJ6TORP****VRG"or what-ever it named your device" > and when you see your (My-Backup) folder STOP... now click the folder button bottom right again, and you're presented with a screen saying moving blah blah blah : to : blah blah blah...
just swipe to move it there.
once you've done that click the back arrow to leave file manager and back out to the main twrp screen again...
Now click Restore>select storage> Micro Sdcard >ok and you should see two things to choose from...
(My-Backup) " the one you created earlier "
and
(alcatel-idelXTRA-5059r-LOS16-modded-2019-05-23)
obviously choose the second one (alcatel-idelXTRA-5059r-LOS16-modded-2019-05-23)
it'll ask you which partitons to restore
make sure ALL of the available boxes are checked should be boot, recovery, cache, and system
then swipe to restore...
after that's done we want to make sure we don't have any issues so back out to the main twrp screen
go to Wipe>Advanced Wipe and choose Dalvik/art Cache and also Cache and Data
swipe to wipe.
then back out once more and goto Wipe>Format Data and type yes and click the blue check mark on the keyboard to continue
after formating data
back out to main twrp screen and go to Reboot>System and if prompted choose NOT to install TWRP app
it wont work for you any way.
it should now reboot and do the please wait while encrypting your device thing again ...
after it counts down to zero it'll hang so just hold down the power button until it reboots and you'll get los boot animation followed by Los setup wizard.
go ahead and setup your device once completed the setup wizard you'll want to follow the part at the end of Method 1 above to get google apps and playstore working.....
then you're Done.
enjoy
NOTE with method two you'll also have a modified /system/etc/hosts file so you'll basically have ad malware and porn protection too. if you don't want that you can replace the content of your hosts file with
Code:
127.0.0.1 localhost
::1 localhost
from twrp etc.

EDIT Somehow forgot to add the magisk patched boot.img to the file
will upload separately later
EDIT: 2
here's the zip with patched_boot.img
UNZIP IT

Edit 3:
Alternate "Better" recovery. !
there are two other recovery ports and I'd recommend either of them over this TWRP.
That being said, if you use method 2 to restore my back-up above...
Please do so with the twrp linked here as thats what made the back-up.
Here's The link to other better recoverys...
keep digging for it
almost there..

EDIT 4:
Making Magisk Just WORK Dammit!
So here is something Nice, We now can have Magisk root on any Pie GSI's by flashing this zip-file .
NOTE TO THREAD HOPPERZ:
THIS IS INTENDED ONLY FOR THIS DEVICE.
IT WILL LIKELY WORK ALSO ON THE ALCATEL TETRA SINCE THE FILES AND PATH ARE THE SAME
DO NOT FLASH THIS TO ANYTHING ELSE!!!
Credit for this go's to a guy who figured out the lib file was missing in most gsi images,
My-self for putting it all together in a flashable zip.
and to @TheExploitedOne for his help fixing error 6 on my updater script and blindly flashing it first
The-Good-Stuff: https://drive.google.com/open?id=1qgZJyEOfVuN7POv_YKAunm-62oNRFhUb

Credit where it's due:
 @Sloogle_Flugelmann and @riskybusiness
for the thread located:
https://forum.xda-developers.com/android/help/alcatel-idealxtra-5059r-root-t3885536
Which got me thinking....
also 
 @Andy Yan for building the GSI that I used to port this
 @phhusson for all the work on treble and GSI'S that made this possible
 @topjohnwu for magisk
and Alcatel / TCL for making it easy this time.

Ok so I found a way to disable forced encryption.
allowing TWRP to use our /Data partition again Yeay!!!
So here's how to do it...
Download the attached file from this post....
put it on your desktop or what ever folder your working out of...
Extract IT and find fstab.mt6739
open your terminal/CMD window and then boot to TWRP.
once in TWRP go ahead and go to Mounts>vendor
and make sure /vendor partition is mounted...
then go back to the pc and type...
Code:
adb shell rm -rf /vendor/etc/fstab.mt6739
Code:
adb push fstab.mt6739 /vendor/etc/fstab.mt6739
Code:
adb shell chmod 0644 /vendor/etc/fstab.mt6739
now go back over to fone, and in twrp back out to main screen and then go to wipe>format Data >type yes
let it do that....
once finished go ahead and reboot to android system
It'll boot up and takes a few minutes to go through the whole set-up wizard again.
but this time you will NOT see the darn little Encrypting the Krap out of android screen...
PROFIT !!!!!
Method 2:
NO PC NEEDED
Download attached file , EXTRACT IT , move fstab.mt6739 to your external sd card....
reboot to twrp,
in twrp at main screen go to
Mount>vendor and make sure /vendor is mounted, and mount> Micro SD Card make sure you have sdcard mounted...
then hit back arrow.

Network unlock package available now
Ok so I have found a way to network unlock the fone but developing it has cost me nearly $80
I am considering sharing a restore package that you can use to restore a back-up from twrp to get your fone Unlocked for any GSM carrier...
But as I have seen NO ONE post in this thread yet, I'll save it...
I may even make it a gift for anyone who donates anything more than $3 to me for my time effort and expenses in developing all this stuff.
if anyone's interested either hit thanks and post about your interest here...
or shoot me a private message...

Got it fully rooted
I got the los 16 pie gsi rooted through a long combination of dirty hacks that in the end allows the official los 16 addonsu to work correctly.
Don't know if ill ever get around to sharing exact details but I will upload a rooted los 16 rom here very soon
will work on that getting that rooted system.img uploaded sometime this week hopefully

Alcatel Da And Auth Files
I scoured the net and finally took apart another program to get these but here's the AUTH & DA files for this device....
also going to add an archive containing all ALCATEL DA and AUTH files I have now....
of course it seems I'm the only one interested in this device...
so probably no one will ever think to look here for them...
but if you do , And if this helps in any way....
Don't forget to click thanks button

Come a long way on this device...
Too bad no one else seems interested ?

I'll load up a lk.bin that you can flash using root and DD.
I'll include a ReadMe with exact instructions.
For temp root to flash the lk.bin you're gonna want to use mtk-su
I'll include everything needed in a zip and load it up here.
May take me a little bit since I'm hanging with the family for 4th.
Happy 4th of July

Thanks for bringing that to my attention,
I been so busy developing for the tetra lately because no one seemed interested here.
If you go back and re-read OP,
I've added a fastboot fix zip with everything needed and instructions
the zip is for a windows user ,
for linux just replace the ./adb.exe with adb
in the commands issued to pc
Let me know if you need help.

Awesome! Thank you. Yeah I just got this phone as a secondary/backup phone and assumed nobody would even be interested in doing anything with this phone. Was kinda surprised to see any progress.
Also, I recommend using Wordpad because Notepad made it one long line of text

Regardless of what or how many times I try, I always end up on a stuck boot screen with circle crossing the screen on the LOS16 rom.

The issue will be this:
If I modify that in any way and you flash it
You will have a brick .
You can only flash modded images after you unlock the bootloader.
Best advice is to look for older or other copies of firmware from the manufacturer and hopefully one of those will allow you to get fastboot.
Anything not signed by manufacturer will brick u .

Ugh, so it will enter in a red state and it will refuse to boot...
So there's no any way?
PS: I can't find stock FW in any site...

UPDATE: The backup/restore method worked and I was able to get it booted. Thank you so much! This is awesome

What would u like to see for it next?

Ive got several other recoveries for it.
Going to start work on several other device specific
System images for it.
Open for suggestions

I've been intrested a while now!
NOTE: I do have fastboot now from your package
Are you able to upload a copy of the unlocked bootloader images? I currently can't use fastboot because it requires USB 2.0 rather than 3.0 (which is bs in my opinion). I just plan to flash the images and unlock without the data wipe. Thank you again for your work sir!!!!

You'll have to use fastboot to unlock bootloader.
