BLU Quattro 4.5 (440D) GSM Recovery+Root
Hello... I got my BLU Quattro 4.5 (D440) a while back, didn't fuzz with it much right off. The Stock ROM was sluggish at best thought there was even an issue with the Digitizer/screen. But this thread was extremely helpful. I am now running Shendu ROM 4.1.2 one of the suggested ROM's above. I tried the other 2 first and they were mostly in Chineese and I had an especially hard time getting them switched over to English. Either way onward to the point. I have put together a few helpful tips-tricks for my experience with this phone and its phoenix transition to an awesome handset. Thats right now this is my daily driver and I love it! See below hope its helpful.
BLU Quattro 4.5 (440D) GSM Recovery+Root
These steps for this phone only!! Not responsible for any issues.
1. download ROM's, Recovery, & Driver from XDA (this thread)
http://forum.xda-developers.com/show....php?t=2327417
2. Enable USB Debugging! Go into Apps-Settings-DevOptions - Check box for USB Debug
3. Have original USB cord if handy! I tried with a Samsung OEM cable but no luck getting drivers to stick. Use original is best. (If you have one.)
Plug in USB Cord to PC then Phone and see if windows detects drivers. let it. It wont get the ones u need later, but what it does find is for USB storage. (you can move over your ROM's/Gapps to storage, downloads folder is a good spot).
4. Go to... http://junefabrics.com/android/downloadold.php to get pdanet software. Install it and it will give i the right drivers for ADB support. I used 4.01 to match the android version currently on my phone.
5. Extract the Driver provided from XDA. Put it in a folder with the ADB commands. Or you can get it all here... http://downloadandroidrom.com/file/G...usRootNew.zipn <-- I know this isn't for BLU but, if you extract this to a folder, and also add the drivers extracted to it as well this works! I've done it.
6. Extract the English Recovery to the same folder.
7. Turn off your phone. Hold down Vol up and Power button for about 5-9 seconds. Once you see a green screen let go of both. Screen may flicker then go black but the icons at the bottom will stay lit. You are now in APX mode (nvflash) mode. (as stated above in original post)
8. Check your Win 7 PC device manager. For a Phone device with ADB. If you you may need to update driver with the one that came from XDA, but the PDANet software should make it work.
8. Go to the folder and find Recovery.bat file (may have Chinese in file name. Double click and a command prompt window will pop up with a bunch of unknown characters, wait 5 sec then hit enter. The batch file should take of pushing the necessary recovery through ADB to the phone. It will error if it can't.
9. If completes OK. Push power for 7-9 seconds to power off the phone. Hit power like normal to turn it back on. It will boot up like normal (or it should).
10. USB is still connected this whole time and you can open a command prompt window. Navigate to the folder you placed the Recovery into. Something like user/username/desktop/BLU/recovery..etc)
Type ADB devices....it should show you that is is connected to your device. Then type " adb reboot recovery " and the device should reboot, give it some time.
11. Once in recovery. Best to do a backup of the original ROM & system. that way you can get back into recovery if anything goes wrong and wipe out the problem by restoring and starting again.
After you backup === you can get into recovery without the command being typed in or even being connected to your PC.... By holding Vol up + Power till you see the green screen then let go of power but keep holding Vol up till you see the BLU Products boot screen then let go ===
Clockworkmod Recovery should be on your screen.
you can reboot phone now and get back to original with no changes. Or you can venture into the world of loading ROM's (There in your downloads folder if you saved them in Step 3)
ROM 101
BACKUP-BACKUP-BACKUP 1st thing once in Recovery ...can't stress enough how much of trouble you can keep yourself out of by keeping an original backup.
As I stated before the Shendu ROM + Gapps is running smooth and all features I've been trying are working flawlessly!! Thanks to original post for getting me going. Just thought I'd add my 2 Cents.
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!

But for that you have had to install TWRP in the first place...
Mine was stock.
Where is the backup saved?
Mine was rooted + TWRP recovery and I saved my backup on flash drive with TWRP's backup option. I was able to boot into boot menu (pwr + vol-) and it would let me to enter into TWRP only. For me it was enough to initiate a restore process..

Edit: Just came back from an LG lab. Bad news. Need to replace the motherboard. Costs about 200$ !! Can't find anything cheaper on ebay. Guess it's time for a new phone
Edit #2 - SOLVED !!:laugh:

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.
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.
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.

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!

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!

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.

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.

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!!
This procedure has been tested on LENOVO K4 NOTE MARSHMALLOW (S219) and it worked perfectly fine.

Before we start:
Here is the details of my handset

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

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:

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...

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!

My system currently has the lenovo usb driver 1.16, windows 10 mtk vcom preloader & ADB interface driver (by google) properly installed!
Does this work on s230 update marshmallow

Hi everyone! I've used this forum for help rather often, but never made an account until just now.
Recently, I decided to get a new phone. Specifically, an Asus Zenfone 3 Laser(Model number ZC551KL / Z01BDC). However, there's no subforum for this device, and only one mention of this model across all of XDA, which is odd considering it's been out for about 2 weeks in most places, and was announced months ago. The same goes for it's brother the Zenfone 3 Max...even odder when 3/5 Zenfone 3 models have their own forums.
I'd like to know if anyone has set out to root this model of phone, as well as if it has a locked bootloader(as I'm not entirely sure about this, though I doubt it.)
As a sidenote...is there any way to try to get a subforum for this device? I'm fairly certain that it'll be a decent enough device to play around with, much like the Zenfone 2 laser. And I apologize if I placed this in the wrong forum.
z01bdc root
did you even find a method for this? can't find anything for z01bdc

KingRoot?
I used KingRoot to root my old HTC Desire 626g+, and it worked fine, no issues. Does anyone know if this is also the case for the Asus ZenFone Laser 3 (ZC551KL)? I would certainly prefer using KingRoot if it is safe. If you think I should root it another way, why is that method any better?

Can you get into the recovery? If you can, try flashing the ASUS official image from their website. If you want to keep root, flash supersu right after it. Or... which method are you talking about?
It isn't a joke, if you visit the other forum on here with a lot more support, and success, that will be a better place to receive help, since a lot of us that have our phones rooted with that method are on the other forum only. Here's the link.

Hello guys, i also have a ZenFone 3 Laser Droid 7.1.1 and i'm thinking not to root it yet... Even if right now with 7.1.1. Installed is very buggy and slow, Asus announced that in mid 2018 we'll get the new update for Droid 8, which they say will include more awesome features and way less preinstalled garbage apps, so must be a cleaner, faster experience... can't wait for it
Iv'e got a guide but I need 10 posts to post it properly.

Thank you. Did really helped a lot. Beside the fact that the link at point 5 is broken, we don't really need it, as everything is greatly explained, ant the fact that for me Magisk worked when SU bricked my phone, everything else is a GO. Thanks to this guide, i have a ZC551KL rooted, with TWRP. kEEP IT UP :good:
