[GUIDE] Proscan PLT9650G (RockChip RK3126) Tablet, Root, TWRP, etc

*** Use at your own risk these instructions worked for me on MY tablets that is no guarantee they will work for you ***
This is for the ProScan PLT9650G(K-1G-8G) tablet. It has the RockChip RK3126 chipset. The one I am working with was purchased in Canada at the Atlantic Superstore. I will just briefly outline what I needed and had to do to root and install a TWRP recovery on the tablet. See the attachment for the recovery image. I will explain how to get the programs and general steps to make a full backup of the tablet before ever rooting the device. It is a little difficult, and not necessary, but like any backup can be helpful to have around.
Specifications:
The ProScan tablet has:
- Android Lollipop 5.1.1;
- Quad-core Processor, 1.2Mhz;
- 1 GB of DDR3 Memory;
- 8GB Flash Storage;
- 800x480 Screen Resolution.
Backup Overview:
1) Install USB drivers;
2) Put tablet in bootloader mode;
3) Read the different partitions.
Tools Needed:
1) Rockchip Driver Assistant v4.3;
2) Android Tool v2.3.
Detailed Instructions:
This tablet is a newer version and requires at least version 4.3 of the Rockchip Driver Assistant. The older versions (4.1) won't recognize the USB product id (310D) in bootloader mode.
Download the drivers unrar and run DriverInstall.exe. Select uninstall to clean any old drivers and then select install to install the newer ones. I've done this under Windows 7/8.1/10. Since I've done it so often and so many times with different driver version, I can't remember if the bootloader drivers require you install them with the driver signing turned off or not. The problem becomes that the bootloader drivers (under Windows 8+) will fail the driver signing authentication and won't install. The ADB and MTP drivers are signed and will install correctly, but when you boot the tablet in bootloader mode the device will be unrecognized by Windows. If you end up with this problem follow these instructions and then install the drivers.
After testing on a new machine under Windows 10 the drivers install fine. There is no need to boot with driver signing verification turned off.
To put the tablet in bootloader mode follow thes instructions:
1) Unplug tablet (both power and usb);
2) Turnoff tablet;
3) Press and hold the esc and power buttons at the same time;
4) Hold until the stock recovery menu comes up;
5) Press the esc button to go down to the menu item saying bootloader;
6) Press the power button to execute that menu item.
The screen will go blank. Plug the tablet into the computer and it will be recognized as a device type "Class for rockusb devices" in the Windows Device Manager.
Download the Android Tool from the link provided. The link gives a detailed description of how to backup all the partitions. I have included my parameters.txt file that I created. From the standpoint of undoing the root operation described below I believe only the recovery and system partition needs to be saved. But saving all the partitions never hurts. After you have followed the information in the link and saved the partitions you can move on to rooting the device.
One serious warning I have NOT been able to write anything to the device using the Android Tool. It always give me an error and won't even try. The backups we create can be used from within the tablet to restore it later if needed.
Custom Recovery Overview:
1) Root device;
2) Download the image file on the tablet;
3) Flash the recovery partition with the image file.
Tools Needed:
1) KingRoot;
2) Terminal Application;
Root Device:
The device rooted using KingRoot. Startup the tablet and go through the setup process. Download the apk from the link provided. The version used in testing was 4.6.2. You will need to allow "Unknown sources". The app will eventually give a button just try to root. This will eventually work and the tablet will be rooted.
Extract the img file from within the zip file below onto the internal drive. Make sure you put it in the Download directory. If you are doing this from the tablet it should go there if you move it over using the computer make sure you put it in that directory or change the command below to the proper directory.
Install a terminal emulator. Anyone will do, the one I chose is linked above. Open the emulator and type:
Code:
su
at the prompt. KingRoot should prompt you asking if you want to grant root privilege to the command prompt. Then type the command:
Code:
dd if=/sdcard/Download/TWRP_800x480_Unified.img of=/dev/block/rknand_recovery bs=4096
. That's it if you type:
Code:
reboot recovery
the tablet will reboot and TWRP should start up.
Notes:
If you saved the original system partition you can install it using TWRP and effectively unroot the device but keep the TWRP recovery. With the recovery image you can install it over the TWRP and return the tablet to its stock state. I'm giving these tablets to my kids and I wanted a way to return them to the state I bought them plus after I've personalized them for each of my kids I can make a backup in case they do something that messes them up.
This will also work for the PLT1065G but you need to use different recovery/parameters. The kernel is different (looks like a different touchscreen).

Thanks for this. Got one for $50 at Loblaws today. Will attempt rooting.
Got it for my 6 yr old
Edit: Fixed boot issue

It seems the boot issue is still there. Do you ever get this? It will get stuck at the PROSCAN logo display.

I have had it stuck. It was when I was testing things. I can't remember what I did. I do know one time I left it for a day and I noticed the ProScan logo had a flashing cursor in it.

I've been fiddling with it and it seems to be completely random. So I guess it's something we'll have to live with.
I bought it for my 6 year old who's dying to play Pokemon Go. The app runs okay on it. It's just the 'GPS' (or lack of a proper GPS chip) that's a bit slow/inaccurate

Hello I to bought this tablet in Canada I successfully rooted it but is there a reason why no other cameras can be downloaded or Music players or Instagram.

Is thee any chance to unbrick this tablet?
I have one stuck in the boot logo, hard reset wont solve, is there any flash file?

Hellooooo !!
anybody here ?

There is a way to create an SDCARD and it will run from the SDCARD. I've forgotten how . I'm looking at one of my kids cracked ones right now. The touchscreen is cracked so I'm looking at build Ubuntu for it. I'll post when I figure out the SDCARD again.

Reset tablet to factory
I was able to use the factory irmware to reset the tablet from a computer. It will over write any custom recovery, etc. I have been unable to recreate a custom image any changes make the image fail. I found the software I used to create a bootable SDCARD but I can't get it to work keeps failing on creating the MBR. The software was the Rockchip SD Firmware Tool and there is an option to create SD Boot. So far I can only find v1.43 anyone have v1.45?

Let me know here as soon as you just remember anything related to this.
I got another tab like this, screen cracked and I could read off its firmware, so I now have a working firmware waiting to be written...

How did you flash the image? what software did you use,
Thanks.

it's not possible to change the rom or custom image of the tablet to another operating system like ubuntu or linux. It has allow OEM bootloader unlocked in the settings in developer section greyed out and it doesn't allow oem bootloader unlocking 'enabled'. You cannot enable it.
What you are doing is just resetting the factory image. or rom. you can just push the reset button with pin after charging the tablet for 3 hours.
These tablets are not 'cheap' to make and google, cell phone companies subsidize these 'cheap' tablets. so you have to use and pay them when you subscribe to their cell phone 'service' or google advertisements when you use their 'service'.
Lots of vaporware being pushed saying they can unlock something for $40 or downloading tools etc. wasted of time as it's impossible to unlock oem BOOTLOADER if the manufacture has locked it, you cannot install another operating system in the tablet, or smart phone. so don't waste your time.
Only some phones allow oem unlocking bootloader and those are the higher end phones costing $400-$600 for a tablet that are not 'subsidized' by google or you cell phone company as with 'cheap' phone or tablet.

the firmware is not available for download at the manufacture website that should raise alarms about the firmware. I've factory reset the device and now it's having reboot issues, either the firmware is defective or corrupt bootloader etc. The manufacture proscan seems to be selling the devices yet no technical support or even a direct download from the manufacture, downloading firmware from thirdparty servers is security risk. it seems like today lots bogus websites and no technical support from manufacturers in tech devices they sell. and people have to sites like XDA for 'free' technical support. Even Microsoft which makes billions in profits fail to provide proper technical support for some reason. and have to rely on 'free' technical support for bugs and issues with their software and hardware and lots vaporware apps etc.. bogus apps. that don't work.
Rooting gives the user the ability to install and change OEM software. from what i gather so don't waste your time, to root a device, allows the user to delete operating system files. if the manufacture doesn't allow changing the oem software there is nothing you can do. about so don't waste time trying root it or try to install ubuntu or linux on the tablet or smartphone if it's oem LOCKED. bootloader. you cannot unlock it. it's much harder to unlock oem software.

the method to 'restore' factory image or known as 'flashing the rom'
there is no reason to flash the rom etc.
1. just hold the power button and esc button at the same time
2. release the power button wait 2 seconds
and then release the esc button
you should now be in boot up mode.
this unit doesn't allow you to be in bootloader mode. so you CANNOT install another firmware or install linux etc. other than the proscan firmware.
3. press esc to select restore the factory settings
4. press the power button to select
this the easiest way to restore stuck in browser or need to flash the rom
again if the rom is 'corrupt' which is not likely
if that is the case
the option to "apply update from external storage" doesn't seem to work as you cannot mount to flash the rom and reinstall the .img file from the .zip file

"apply update from external storage"
where you saved your .zip doesn't work
the apply updated from ADB works you need a usb computer hooked up to you computer and terminal command to ADB to your table to rinstall the .imge file

update ,this no longer seems to work in installing the .zip file method to install the firmware.
lot of software and hardware that have no technical support or documentation and the stuff just doesn't seem to work and high security risk with no updates from manufacture as it cost them money to resolve issues. selling disposable technology tablets. that is not meant to last. basically toys. for kids.

[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.

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.
SeñorNeusAap said:
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!

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!!

Before we start:
Here is the details of my handset
Model: Lenovo K4 note (PH) [MTK MT6753 8CORE 1.3GHZ 3.00GB RAM]
Model #: A7010a48
OSv: marshmallow 6.0
Android security patch level: April 1, 2016
Kernel ver: 3.18.19+ [email protected] #1, su jun12 18:27:10 CST 2016
Build number: A7010a48_S218_160612_ROW
Step 1:
download all necessary files.
all files and links are not mine and credit goes to the owner of the files
adb tools : https://drive.google.com/open?id=0B16daNyhWTx1djhqSkJ6QkFKaUk...
recovery(i.e TWRP) : https://drive.google.com/open?id=0B16daNyhWTx1RlB0U01sUkVHMjg...

xposed framework : https://drive.google.com/open?id=0B16daNyhWTx1QmlRTHhXOUMydDQ...
step 2:
a. back up any necessary files from your handset.
b. since some computers doesn't show your lenovo k4 note while on recovery mode, it is imperative to put aroma file manager and supersu on your sd card. "do not extract. just copy them as it is"
take note that the next step will definitely hard reset your device.
step 3:
a. enable developer option on your handset. go to system settings/about and click build 7x or as it says "you are now a developer"
b. go to developer option do this two things
enable oem unlock
allow usb debugging
c. once you are done please connect your device to your laptop
step 4:
a. run adb server (go to adb folder, shift+right mouse click and choose open command window here.
b. it will prompt you to allow your pc to connect/control your devices just click YES
c. on your command window, type ADB DEVICES (it will detect your lenovo k4 note)
d. once detected type ADB REBOOT-BOOTLOADER (your device will reboot)
e. once rebooted, type FASTBOOT DEVICES to verify if you are already in fastboot mode
f. if connected proceed to step 5. if not please repeat procedure
step 5:
a. once connected go to adb folder on your computer. you will see a file named unlock recovery.bat
if not, copy this text
call adb.exe devices
call adb.exe reboot bootloader
call fastboot.exe getvar all
call fastboot.exe oem unlock
call fastboot.exe format userdata
call fastboot.exe erase recovery
call fastboot.exe flash recovery recovery/recovery.by.gursewak.img
call fastboot.exe getvar all
call fastboot.exe reboot
echo done successful please press any key to continue
echo disconnect your phone and press power button untill phone reboots
pause
Click to expand...
Click to collapse
to notepad and save as batch file, name it as UNLOCK_RECOVERY.bat
b. click the UNLOCK_RECOVERY.BAT then it will ask you on your device to confirm, (will add screen shot later on) just press volume up button
c. once the process has been done, (will take few seconds) extract recovery.img to adb folder
d. go to your previously opened command window and type
FASTBOOT FLASH RECOVERY RECOVERY.IMG (the one you extracted)
step 6:
a. once flashed, disconnect your device (it will show a tiny text telling you transmission ok)
b. press and hold the power button for few seconds to turn off the device
IT IS IMPERATIVE THAT YOU WON'T TURN ON THE DEVICE UNLESS THE NEXT STEPS ARE DONE. IF YOU ACCIDENTALLY TURNED ON YOUR DEVICE REPEAT TO STEP 1.
c. press and hold vol up+vol down+ powerbutton simultaneously for few seconds, once you felt a vibration, release power button whilst still holding the vol up and down button
it will show the lenovo screen then go black. (don't worry it means you successfully flashed recovery.img)
d. connect the device to your computer
if lenovo shows on your device, now is the time to recopy aroma file manager and supersu. if not just wait for the screen to turn back on.
e. once twrp recovery is on, go to mount and check SYSTEM. (do not touch anything aside what i unstructed)
d. go back to previous menu and go to install
install aroma file manager and wait for it to finish
f. once installed it will go directly to aroma file manager, go to system folder and scroll down. look for recovery-from-boot.p and delet it
g. once deleted exit aroma file manager (button can be found on right corner)
h. go back and install beta supersu which you copied. (browse sd card)
i. once flashed, reboot system,
step 7:
a. if you made it this far, then you are almost done.
b. just finish the lenovo start up.
c. once done, connect your device again on your computer and copy xposed apk and xposed arm to internal or sdcard
d. install xposed apk
e. turn off your device
step8:
a. reboot to recovery (press vol up and down and power button simultaneously, once you felt a vibration release power button whilst holding vol up and down button. lenovo screen will show and it will eventually go to twrp recovery)
b. click install and install xposed arm
c. onced install. reboot system.
THERE YOU GO... YOU ARE DONE. YOU CAN VERIFY ROOT BY DOWNLOADING ROOT CHECKER FROM GOOGLE PLAY STORE.
WELL I WAS FORCED TO ROOT MY K4 NOTE JUST TO PLAY POKEMON GO.
I WILL UPLOAD SCREEN SHOT ONCE I ALREADY COMPILED THEM. THANK YOU
IF YOU LIKE AND HELPED YOU A LOT PLEASE HIT THANKS AND LEAVE A MSG.
IF YOU HAVE QUESTIONS, JUST COMMENT IT HERE.

Thanks it worked. I was about to complain when twrp recovery does not show up. BUT IT WORKED THANKS

xposed isn't necessary to root the phone. Am I right? Maybe you should explain that in the OP. You'll get people confused down the road if they don't already know what they're flashing.

Will it work on s219?
I just badly wanna root amd this is the easiest way i found..
Thanks:cyclops:
And yes,one more question,
During unlocking the bootloader, will it only format my phone or both phone and sd card?

hi
will it erase internal phone memory (i mean after flushing ROM can i get my data using any recovery software)
i am also using same s219 Rom model lenovo k4 note phone.
Actually i deleted some files unexpectedly from internal memory but i want them back, so i tried many ways but no software is identifying internal memory as a drive. I tried to root using root apps but marshmallow not allowing.
i found this topic, but i have only doubt is after flushing the rom can i recover my data using any recovery software?
Thanks in advance

thank you so much!
now to answer some queries and give thanks...
@Duffy144: glad you like it.
@Bdwilk: thank you for the input, i will do that.
@infected_162k: i haven't tried yet since i haven't been able to check latest OTA, but i will try it now since s218 causes lag and memory leak when using facebook messenger. and as you've said. thanks for the confirmation for s219, at least i am more confident. btw, does this really solve the memory leak of the s218?
@anvesh.k yes it will delete all files as the procedure requires you to factory reset your handset.

Rooted K4 Marshmallow
Damn. Finally. I got root. Can finally get rid of that Cell Broadcast. Thanks Sir ansei. The unlocking of bootloader, flashing of twrp and supersu process is pretty much straight forward and will only take you about less than 10 minutes.
Am not sure if this is a systemless root i have. If so, it's great. I am on S_219. Zero performance or stability issues.
I feel my K4 Note runs smoother and snappier compared to S150 row. Still getting the hang of the revamped user interface though.
Overall, Marshmallow 6.0 S_219 runs great with unlocked bootloader, twrp and supersu.

Can someone confirm if this works with 2 gb / 32 variant?

Amm, about that memory leak thing, i basically know what that is cause it was a huge problem in my father's phone(gionee m3). But i exactly don't know how to know if it's still there or not as I use messenger hardly 2-3 times a week. guide me about this so I can tell you exactly.
Another thing that will help other users: I have to factory reset my phone due to a google error ( unable to communicate with Google server). I was not sure about root and xposed will be gone or not. But here is the result : lost both, root and xposed. Just flashed both again, super su and xposed framwork, worked

Old data? Not sure what you are referring to. After the unlocking of bootloader, flashing or twrp and root, restarted the phone in normal mode. Went through the setup wizard and all. Reinstalled my usual stuff. Back to where I left in Lollipop. Zero issues with Marshmallow 6.0 S_219.
Sir Ansei, everything is fine except 1 minor issue, when rebooting to TWRP, I often get the black screen. Power cycling the phone works. Any ideas?

May be what he trying to tell is he accidentally deleted some of his important stuff and now he wants to get it back with the apps that use root to dig around. But as per my experience, it only work if that portion of sd card of internal storage is stayed untouched not if overwritten by something else. But if you already rooted, just give it a try...maybe you'll be lucky...

Thanks for understanding my problem

call fastboot.exe flash recovery recovery/recovery.by.gursewak.img - needs to be edited? make sure path is correct and image name.
call fastboot.exe flash recovery recovery.img
Just put recovery.img in the same folder

I cannot get fastboot to recognize my device & perform the bootloader unlock. Whenever I type in " adb reboot bootloader" or click on that "unlock_recovery.bat" file, I get booted into a dark screen where "fastboot" is written at the bottom & the command prompt window says < waiting for device> & I am stuck there until I reboot my phone.
Please tell how to get past this!

[GUIDE][ROOT] How to Root the CAT s60 ... ... and more !!!

EDIT 2019: rooting with TWRP from 038 read at the bottom of this post
HOW TO.... Stock, Update, custom recovery and root your s60 !!!!
Disclaimer: if you brick your phone, it's your fault, i have tested this way of rooting my s60 now for a several times and it works 100%
SO READ TWICE, CHECK TWICE, BEFORE YOU CLICK ONCE !!!!! i will not take any responsibility !!!
!!! ONCE AGAIN, READ THE WHOLE GUIDE BEFORE YOU START !!!
OK, now we start:
Thanks to everybody who contributed and made the root possible, here in this thread (Cesarq, OpenMinded, Tuschi, BetonJohn, etc.......) the software in the link further down, is the collected data, freely available in the net and linked in the original Thread several times, i have only bundled one package and wrote this, hopefully usefull guide.
in principle do as follows: (I will only explain once how to sideload or load via recovery, afterwards i will only state what kind and what file)
Prerequisites
- switch phone OFF
- download my collection of the essential s60 files : Here is my collection
EDIT 2019: - grap the 035 update here from the Thread: Thanks to tusch00101
i did not find the 038 update as a single zip file to download. if somebody could provide it ?
(there are ALL files included to flash stock, update to .035, flash twrp recovery and root.)
(this is for Win7 x86, you have to check if it works for other versions yourself, sy..)
- install USB drivers
(for recovery and adb !!! There are two different USB drivers needed)
- install "minimal ADB and fastboot"
- copy the two updates (update032.zip & update033.zip) into the folder, where you have installed "minimal ADB and fastboot" (makes live easier later)
- install QPST (the version of QPST is the one from Androidmtk and should be virusfree.)
(The version of QFIL in my collection is the one without reboot, so you have to reset/reboot your phone manually (resetbutton below hatchdoor on your phone) whenever stated in this guide.)
- format micro SD card in fat32 ! and copy SuperSU.zip onto it. Then insert microSD card into your phone.
- switch phone ON
- enable Developer Options, by going into the settings menu and go to "About Device". tip/touch/tap 7x the -build number- field. A message will appear: "You're now developer" (something like this)
- enable USB-debugging. Go again to settings, then "Developer Options" and enable USB-debugging.(flick the switch)
- connect a WORKING USB cable to your phone (Not to your PC atm !!!)
- dial *#06# to see the iMEI('s) of either one or both simslots. dial #02# to check what firmware version you are on
(just for your info: It looks like the "S" in the firmware version (LTE_X.....) indicates, that SingleSim only is activated, while the "D" stands for DualSim activated. my s60 had an "S"... )
(In my phone the second Sim slot (under the microSD card slot), was blocked with a small piece of, simcard shaped, black plastic. With the help of some tweezers the scrap
plastic was gone easily. Anyway --- BE CAREFULL --- when removing it.)
If you are allready on an LTE_D... Firmware version 033 or above (atm only confirmed up to 035) and you want to root with custom recovery, you only need to follow the last step in this guide ("getting twrp and Root") everybody else, continue reading...
getting twrp (for saving your old firmware only)
- power off phone.
- start minimal adb on your PC
- start QFIL (part of QPST) on your PC
- press VOL+ & VOL- simultanousely and connect phone with PC (it will vibrate once, top right LED starts blinking red, screen stays black) (- DOWNLOAD MODE -)
(just in case: to leave Download mode, disconnect phone from PC, press and hold power button for apprx. 15 seconds)
- as soon as you connect your phone to the PC, QFIL should show the Phone/port in the topline allready
(if not, either try to manually select the port, or you probably still have a problem with the USB drivers or the USB cable !)
- QFIL - tick "Flat Build" (top left)
- QFIL - select Programmer, "browse" to the saved location of "update-twrp-recovery-nobootpatch" and select the "prog_emmc.blablabla...mbn" file and doubleclick
- QFIL - "load XML" ,select rawprogramm, doubleclick, select patch0, doubleclick
- QFIL - click on "download"
- if everything was OK up till now, it should start download - BE PATIENT- and read the status window on QFIL, when it shows "finish download"....
- disconnect phone from PC
- press and hold simultanousely POWER and VOL+ (- RECOVERY MODE -) AND...
- ... use a small tool to push the reset button on the phone under the hatch, while still pressing Power and Vol+ !
- the phone should now be in twrp recovery. If so, do a full backup now to your (allready inserted and fat32 formatted) microSD card!!!
when done
- Power off your phone !
flashing stock 31.02
- enter download mode again (Vol+ & Vol-, connect phone to PC.......)
- this time in QFIL, browse in programmer path to "s60_stockFW_31.02" and select the programmer from there
- load XML's (the ones that belong to Stock31.02)
- start download... this will take a while !!!! BE PATIENT !!!!
- when QFIL status window shows finish download, push the reset button on the phone and let it reboot.
(it is normal, that the phone should restart itself 2, maximum 3 times during the first startup, but sometimes it ends up in a bootloop (Cat Logo, reboot, CAT logo, reboot, etc, etc, .......))
(The bootloop mainly happens, if you clear, in twrp recovery, the whole OS, or if you came from another firmware version (LTE_S... -> LTE_D... i.e., but that's no issue either...).
- if it ends up in a bootloop, no worries, just continue ! Believe me, i did this process now several times !
you are back on stock 31.02 !
- Power off your phone again
Updating to 032
- bring up minimal ADB sideload on your PC (start it, if not allready done in previous step (getting twrp)).
- press and hold POWER and VOL+ button on your phone
- when in stock recovery select (with Volume keys) "adb sideload" and click the Powerbutton
- connect your phone to the PC
- on PC, type into the black ADB Terminal window "adb sideload update032.zip" and hit enter
- if correct USB drivers are installed, phone will start downloading the update now.
- when complete, select clear cache, and clear data then reboot your phone.
(again, same as in the step (flashing stock), if bootloop, no worries, just continue, if it boots up, let it boot up and then..)
you're on 032 now
- Power off the phone again
Updating to 033
- do the same steps as described under "Updating to 032" only difference, type in adb window " adb sideload update033.zip"
EDIT2019: - do the same steps for 035 and 038
(After updating to 038, your phone should boot up normally by now. NO MORE BOOTLOOP !)
getting twrp and Root
- this is the same step as above "getting twrp" only difference, this time, no backup needed and...
- when in twrp-recovery, select "install" browse to your micro SD-card, and...
- install SuperSU.zip from SDcard.
- once more, clear cache and data and reboot.
The phone should boot up now, you should be on FW 033, with custom recovery and root !!!
That's all !!!
Oh, one last thing, whoever is having an s60, where only one simslot is working, this guide unlocks the second Simslot as well !!!
Also the problem, some people had, following the other guides (incorrectly) ! (me included) ! , by not using the right QFIL (the one without reboot), in the old Thread, resulting in a
not working WIFI is no issue anymore
EDIT 2019 !!!
Getting TWRP with stock 038 thanks to: CDMCCDMC for the addition !
https://forum.xda-developers.com/showpost.php?p=77978181&postcount=135

thanks for the awesome guide. works perfectly, but i will say every time I plugged my phone in it recognized it as a new device and had to reinstall drivers.... the first few times i did it i thought QFIL froze so i unplugged to reset, this caused an install failure that could not be rectified. I fixed this by uninstalling and reinstalling the drivers from step one and being more patient.

Dear adtbm,
the firmware updates (both) are extracted... became signature failure.
Please update your very useful package... thx
best regards

If you don't have Wifi after going to 033, you didn't followed the part of "getting twrp" correctly.
"...... - if everything was OK up till now, it should start download - BE PATIENT- and read the status window on QFIL, when it shows "finish download"....
- disconnect phone from PC
- press and hold simultanousely POWER and VOL+ (- RECOVERY MODE -) AND...

- the phone should now be in twrp recovery. ....."
If you let the phone reboot after flashing the recovery, it will overwrite the boot and your wifi is gone !
But nice to hear, that everything is OK now. Do you have problems with 035 ? some people report, that they having issues with the display camera on 035 ...

Sorry for this silly question, but i´ve seen that in other models once you install twrp then you can flash super su, why here you have to downgrade to 0.31 first?
Thank you in advance.

Hi,
not sure, if you have read the complete guide, or if you have read through the 28 pages of the original Thread.
I think, it could be possible, (but i did not tested it) to flash the recovery via QFIL directly and then install SuperSU, without going back to 031. But since there are models of the s60 out, where only one Simslot is available (Please read my guide), to get the second slot activated you have to flash an LTE_D... firmware and, thanks to Cesarq, we (only) have atm his 031 firmware available, which is luckywise an LTE_D. firmware !
Like i mentioned in this guide allready, i did not found out the way how to root the s60 (the credit goes to Cesarq) and i also did not find out, how to update to 033 (this credit goes to OpenMinded), i have only collected the software & tools, bundled it and wrote this guide, with the available information written throughout the 28 pages of the original Thread.
So please feel free and test it and write us your result !

ok, just did my s60 last night, everything seemed to go just as described. i just checked and it seems it took the update and the dual sim activation. it didnt take root tho. i tried root checker and titanium and both say no root access. maybe i did the final step wrong? i tried it again with no success. am i supposed to be loading the nobootpatch recovery in qfil as the last step and then install su? thats how i attempted it. any help would be greatly appreciated. thanks in advance!

I asume, you have SuperSU copied onto your microSC card ?!
When you have finished flashing the nobootpatch recovery (QFIL shows finish download), you have to disconnect the phone from the PC, push Vol+ and Power and Reset (under the hatch) at the same time.
Otherwise Bootloader gets overwritten, your Wifi is gone, no custom recovery and no root.
If you are not using the version of QFIL from my package, you probably have a version that automatically reboots when download is finished and you're screwed !!!
If you did it correctly your phone should boot into twrp custom recovery and you should be able to install SuperSU from SD.

Yes I did have it copied and installed it. I went back and did it again and hit wipe dalvic cache instead of going back in the recovery menu and wiping cache and data. Up and running 33 rooted, everything seems good so far! Thanks [emoji2]

I took your advice and rooted without downgrading firmware. My CAT is double SIM from factory and on 0.35 OTA.
I followed your guide but jumped from backup with twrp to install supersu, following all the steps from there.
Until now everything working fine with root.
One more time I can say that people on XDA is the best!

Dear friends,
How can i uninstall google assistant apk?
When i delete it the phone not restart and ended in a bootloop.
When i deactivate it the same bootloop.

very very good
Hello to this wonderful group. I did the rooting and it worked wonders, I was very disappointed with my Cat s60, for not being able to use the second sim and for the poor quality of the camera. After the root it became dualsim and the camera improved a lot. in addition to everything that means to be root. I am very grateful to ADTBM and to all those who made this possible. thanks thanks. regards

Hi Yanardag,
i have the same problem. Unfortunatley Android IS Google . I really don't know how to disable it. Did you try to freeze it with Titanium ?
That's the only thing i could think of. I am annoyed by that Google stuff as well (especially the google assistant....)
This is one of the reasons, why i had to redo my s60 a several times.
So if anybody here finds a way to disable Google assistant, pleasse let us know !!!
@varonv: Nice to hear and thanks for the feedback !

Hi,
I am on 027 now. No OTA update available. Can I try this guide?
Thanks

This Guide works on win 10 also. .. But ending in Win 10 Test mode

[Guide] Upgrade to Windows 10 15063, bootloader unlock, root, interop unlock

If you're one of those who has never touched a windows phone before, this guide is for you.
Prerequisites: Windows Device Recovery Tool and internet access on your phone.
Warning
If you've updated to Win10 using insider and you're not getting any updates for fall creators update, follow the guide from start to finish. Don't skip to step 3 just because your phone is already on Win10. Having a carrier branded ROM can cause issues.
STEP 1: Flash unbranded ROM
Since AT&T never provided a version above 8.10.12393.890 and the insider program has been shut down, you must flash an unbranded ROM before you can upgrade to Windows 10. PHONE/SIM WILL NOT WORK, so if you care about receiving phone calls then don't bother.
1. Download an unbranded ROM here, "RM-915 VAR BR CV": https://www.lumiafirmware.com/model/RM-915/hwid/059S2X9
1b. Click 3058.50000.1424.0002
1c. Just download the ffu. You don't need anything else.
2. Open an admin command prompt, cd "%ProgramFiles(x86)%\Microsoft Care Suite\Windows Device Recovery Tool"
You might want to rename your ffu file to firmware.ffu to make it easier to type since you can't drag files into an admin command prompt.
3. type thor2 -mode uefiflash -ffufile "C:\SomeLocationHere\yourfile.ffu" -do_full_nvi_update -do_factory_reset -reboot
Where C:\SomeLocationHere is the location to the file, of course
3b. If your phone is stuck in flashing mode for some reason type "thor2 -mode rnd -bootnormalmode"
4. After it installs and reboots, set up the phone again. Yes it will be in another language. proximo means continue. You can probably get through the setup without too much issues. Aplicativos means it's installing the apps, just wait 15-30 minutes and it should be done.
5. Turn on airplane mode or it will reboot every 10 minutes. Yes, really. Head to settings, idioma, add "Ingles" or your preferred language, hold down, press the second option (move up), hold down on portugese, press the first option (remove), press the reboot button.
6. Head to the software update section and update your device. It will take an update for an update to show, so be patient! If it says there are no updates available after an hour, please message me or if you're feeling adventurous you can try with "RM-915 VAR APAC AU TELSTRA" instead of the Brazillian ROM.
STEP 2: Update to Windows 10
Make sure you've done step 1 so your software version is 8.10.14219.341 or newer, since you cannot use SOUP on an older version.
1. Get SOUP from this guide.
2. Double click run_en.cmd and follow the rest of the instructions.
STEP 3: Interop Unlock:
1. Unlock the bootloader, enable mass storage, and root using this guide. Yes, you can use the .ffu for Windows 8.1 to unlock your Windows 10 Nokia.
2. Go to settings, search developer, tap the result that says "For developers".
3. Set it to Developer mode.
4. Set the date back to a time before Nov 24 2018 and reboot. The Interop Tools cert expired so it won't install if it's past that date.
5. Download Interop Tools, extract it, then copy it to your phone's storage over USB.
6. Open the File Explorer app on your phone, navigate to the directory you copied over, and install the files in /Dependencies/arm. Note that there is no installation progress indicator so please wait 30 seconds-1 minute before installing the next one or the app will not install.
7. Install the InteropTools appxbundle.
8. Open Interop Tools, go to the interop unlock section
8b. DO NOT TAP THE STORAGE UNLOCK SWITCH!!! USB WILL STOP WORKING! (You can turn it back off anyways if you accidentally turned it on)
9. tap the interop unlock switches and restore NVDK. Your phone is now Interop Unlocked!
STEP 4: Update to Fall Creators Update
You need to make your phone appear as a Lumia 950 XL.
1. Open Interop Tools, go to the registry editor
2. Navigate to HKLM\SYSTEM\Platform\DeviceTargetingInfo
3. Change the values to the following:
PhoneHardwareVariant : RM-1085
PhoneManufacturer : MicrosoftMDG
PhoneManufacturerModelName : RM-1085_11302
PhoneModelName : Lumia 950 XL
4. Reboot
5. Check for updates
6. Update the phone (You might have to wait a few hours before any updates appear)
7. Repeat steps 5 and 6 until you reach 15063
If you ever want to change back, the original values are:
PhoneHardwareVariant: RM-915
PhoneManufacturer: NOKIA
PhoneManufacturerModelName: RM-915_nam_usa_228 (Your phone might be different, best to keep it backed up!)
PhoneModelName: Lumia 520

If you're one of those who has never touched a windows phone before, this guide is for you.
Installing Windows 10 Mobile:
Online update method:
1. Download the Windows Insider app from the store.
2. Follow the steps to register your account as an insider (if you haven't already done so).
3. Select Insider Fast. It should register your phone after a while.
4. Go to settings and check for updates. This step can take a very long time, so be patient and wait about half an hour. (It might even take days if the servers are running slow).
5. After waiting 1000 years for the update to appear, download and install.
6. Keep going to the settings app and installing any new updates that appear...
Offline update method:
Make sure you've done steps 1-4 of the online update so your software version is 8.10.14219.341 or newer.
1. Get update files from this guide.
2. Use the 2nd Generation\480x800 folder, then run iutool like the guide tells you.
3. After iutool copies all the files and says "Updating system" or such, go to settings -> check for updates to see the progress of the update installation. Now you just have to wait for about two hours for it to complete.
Updating to the latest (unsupported) version of Windows 10 Mobile:
First you must do the Interop Unlock, so scroll below and then come back to this section...

I'll have a try with a RM-914 now in 2021, if I reach 1709 I'll be happy !!

STEP 1: Flash unbranded ROM
Since AT&T never provided a version above 8.10.12393.890 and the insider program has been shut down, you must flash an unbranded ROM before you can upgrade to Windows 10. PHONE/SIM WILL NOT WORK, so if you care about receiving phone calls then don't bother.

Is this a AT&T limitation that unbranded rom won't let you get sim working?
