[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!

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.

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.

2.5 Unlocking the bootloader (you might not have to do this)
Only do this step if you get a BROM error with code 6045 when trying to flash any roms. Here is how you unlock the bootloader:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
3. Flashing the Chinese Firmware
In the Chinese firmware folder, there will be 4 sub-folders: SD_Upgrade, Update Tool, USB_DRV, USB_Upgrade.
0. Delete the SD_Upgrade folder (Not needed).
1. Go to USB_DRV and install the .exe file in the: "Driver For servers 2012-11-27" rar file.
2. After this open the Update Tool folder and extract files.
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file.
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
4. Flashing the: "G750-U10 to G750-T00" Firmware
This will be almost the same as part 3.
Extract the "G750-T00_mod8_265_FlashTool" rar file, and:
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file (make sure that you select the scatter file from the new rar file, and that you are not using the same one as before).
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
5. Restoring your NVRam and IMEI
You might need to root your device again, check if need be, by searching for an app called SuperSU or RootKing. If they are not present, root the device again with Root Genius.
You will need to re-install the "adbd" app on your new ROM. If there is no Play Store present, search for a Play Store APK on Google. Once, installed check the 2 tickboxes and re-open MTK Droid Tools.
Click on the "IMEI/NVRAM" button restore your backed-up NVRAM and retype you IMEI codes. Once the restores are done, restart the phone and check if you can call someone. If it works, good job! You can now progress to the very last step! If not, check if you entered the IMEI correct. You probably made a Typo.
6. Installing final ROM
Now that you have installed pavel22's ROM, you have access to a recovery system. So copy the whole 3rd zip file to the root folder of you device. Turn off your device, and turn it on again but this time while holding both volume buttons and the power button until TWRP opens. Click on install, search your zip file and swipe right. When it finishes, do a factory reset from TWRP and then reboot the system normally. You should now have a fully working G750-U10 with Android 4.4.2. Congratulations!
This was my tutorial and personal experience with converting my G750-U10 to Android 4.4.2. It has been a wild ride, and i've reached points that I wanted to throw my device against the wall. I'm now very happy with my (feeling like) new device. I can now finally catch 'em all and become the best PokéMaster ever!

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

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

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

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

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

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

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

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

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

What a way to rip-off runningnak3d's guide.
I mean, I can understand rewriting it... I did the same. But, just to parse it out for me to follow better.
But your statement "...there was no root guides available..." is just BS.
Below is my guide... for me to do the process.
Creation date on the text file was November 7, 2017. Just over a week after runningnak3d made the original post.
Difference is, I didn't feel the need to post someone else's work, in an attempt to try claiming credit for it, due to nothing more than a "rewrite".
What you meant to do is this: (FIFY)
Cool guide for rooting your LG V20. Works for 20h, too!

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

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

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

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

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

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

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

Blackview BV9800 PRO Rugged Beast MAGISK ROOT REQUIRED

Hi everyone,
I have rooted my last few smartphones and was always happy with it. Now I got new Blackview BV9800 PRO and I want to root it with Magisk. but as the phone is new, there is lack of information on the internet, Anyway, I have found some information, but it is not complete and I believe You, smart guys, can help me to root my smartphone
This is the information I got:
How to root it with Magisk :
Download your rom from : viewtopic.php?f=285&t=532354 (you can alternatively extract it with SP Flash Tool and WWR)
Download and install Magisk Manager on your phone : https://github.com/topjohnwu/Magisk/rel ... v7.5.0.apk
Patch the boot image with Magisk Manager
Unlock the bootloader. (Wipe the phone! )
Flash the patched boot image with SP Flash Tool or Fastboot. (ONLY the boot image)
Reinstall Magisk Manager
This is what I did and what happened:
I installed latest Magisk apk from official sources. I opened the app, clicked on "Install Magisk", then via this app I downloaded the zip file, then tried to installed it via Magisk but got an error "Unsupported/Unknown image format".
Any ideas what have I done wrong? Did I have to flash boot image from the ROM, and not the one Magisk downloaded? P.S., the smartphone is new, nothing more then I written above is done to it (no oem unlocking, no usb debugging, etc).

RESERVED

I let Magisk manager patch the original boot.img. After flashing it with fastboot or SP Flash the phone stuck with message that verified boot didn't accept the signature.

Hm... Is there anyone who rooted BV9800 Pro successfuly and could guide us? ?

update fail.
I greet you, I accidentally deleted it when I updated, Nvram. on my phone. BV9800pro. It is possible to provide me with firmware recovered from a similar phone. I also posted on the forum at Blackview but without answer

Isn't there a full firmware download on Blackview website available? I thought I've seen it there

Hello
Yesterday during an update, by accident, my equipment, BV9800pro, performed a complete formatting, "Full Format + Dowload", it seems that Nvram has also been rewritten. it is possible to provide us with a solution or file with this data, specific to our equipment. i need a original nvram.bin, and nvram.data, in firmware from Blackview site this its not exist..
if someone wants to help me, I send them a private message with their email address

My phone is not rooted unfortunatelly, if I can help in anyway (if there is a way) I would pull out the files for You.
Do You know how to guaranteed root BV9800 Pro without running into problems?

who guarantees this?
rooting worked for me with that solution given to the PM. I wanted to install AOSP, but I found that the thermal image did not work anymore, there were some problems when previewing the video files from Facebook, and I gave up. from the mistake as I mentioned I format + dowload and delete all important partitions. nvram .bin si nvdata. Nothing works properly, TEE and Google Key are inactive, the thermal image fails, some applications are closed immediately. This is the experience with rooting and installing AOSP on the BV9800Pro

Oh man... Sounds bad... have You emailed blackview after sale support (via email, not forum)? No response from them?
And let's say I only root my BV9800Pro, will I be able to send You the files You need?

As I mention there's no TWRP available for this phone yet.

I just rooted BV9800 pro yesterday.
You don't need to SP flash tool or others, just need adb and fastboot.
Quick steps:
1. set OEM unlock to allow
2. connect phone to windows
3. use adb to check if connecting. command: adb devices
4. using adb to reboot to bootloader, command: adb reboot bootloader
5. And then the phone will enter fastboot mode ( you could see small string at left bottom corner)
6. use fastboot command to unlock bootloader. command: fastboot flashing unlock
7. If fastboot program is waiting, please check windows device manager, there should be an unknown device, let windows search driver automatically. it needs android interface driver.
8.Using volume up or down to agree unlock.
9. If agree, all data will be disappeared.
10. Install Magisk manger
11. Download stock ROM from blackview forum. it is zip file. Unzip it and copy boot-verified.img to phone.
12. patch boot.img by Magisk manger.
13. Copy patch image file to windows
14. use adb to reboot phone to fastboot mode
15. reflash boot image file. command: fastboot flash boot patched file name (normally, I would put patch image file in the same folder of fastboot)
16. reboot (fastboot reboot) and reinstall Magisk manager
There are many Magisk root steps instruction in internet. You could refer to other steps, they should be clear than mine. I prepared lots of drivers and application. Finally, I only used adb and fastboot to root this phone.

I rooted it exactly like You and it worked perfectly! Thanks for auch detailed rooting guide!
By the way guys, I think we Should open the request for TWRP for BV9800Pro. How do You think?

After you unlocked bootloader, it changed to orange state, and it always shows "Your device has been unlocked and can't be trusted..Your device will boot in 5 seconds", it could be resolved by modified LK image.
Refer to
1. https://forum.hovatek.com/thread-31664.html
2. http://bbs.blackview.hk/viewtopic.php?f=286&t=532899 -- included modified LK image
Of course, you could reflash by fastboot, no need to use SP flash tool.

hi if u have back up on your phone could u provide for me link. I had some problems with my loudspeaker and i thought its from the root, or software and i did full format and download. and now it show some watermark and probably is because i l deleted NVRAM.
i download already official version but didn't help ... thank u upfront.

Hi, I'm not rooted (yet) and my BV9800 PRO is having some issues with the loudspeaker, any media like YouTube or Spotify, play audio for a second or two and then just go mute, volume can be high but no audio at all, phone calls last longer but also go mute and have to go back to regular "ear-speaker" to keep listen to the other side. Are this the same problems you refer to? I can't remember if this happened after the OTA update tho. Thank you.

How To Guide The Complete Noob Guide to Rooting Moto G Stylus (2022) XT-2211 Mediatek Variant

This is NOT for the 2021 Moto 5G Stylus. This guide is exclusively for the Moto 5G Stylus 2022.
This tutorial is for people like me than just got the Moto 5G Stylus XT2211 (Factory Unlocked Mediatek Variant) running on stock Android 11. I got this phone literally Sunday brand new in the box from Best Buy (Yes, I took a Chance and copped it from them hoping it could be bootloader unlocked). This is a hand holding guide for the Noobs that really are intimidated by rooting their device, so even though there are other guides up, this one is for people like me that need every step explained.
Follow the following at your own risk! I am not responsible for any mishaps with your devices.
I've been rooting Motorola phones now for five years, so I'm pretty handy as a script kiddie (I know bad word) in doing it. I also was pretty active with my last phone over at the Moto One 5G Ace Forums, so here's to hoping my progress with these phones continues.
Thanks to Android 11 being System As Root with all these new super partitions running amuck (like Android 10), you cannot get Write access in the actual system files. So even when you achieve root, you can't do much without getting a script and accessing those partions. @lebigmac and @munjeni have been constantly working on that. Drop by their respective threads on R/W access and beta test his script so he can get more knowledge about how Moto phones work so we can have easy R/W access like Xiaomi and Huawei phones.
Introduction/Preparation
First, go and prepare by READING EVERYTHING. Very important. This is the Mediatek variant and NOT the Qualcomm variant. Flashing does make a difference between the two. Last thing you want to do is brick the device because you flashed the wrong firmware to the wrong processor, or you flashed other software for the other similar Moto One 5G Stylus (2021) and it bricked. This is the MILAN version.
Second, unlock the bootloader. All T-Mobile and their subsidiary variants can be unlocked by Motorola as well as International and Motorola factory variants; go to their bootloader official unlock site and follow their instructions, it's easy peasy. If you do it in firefox it may not go to the third step page and hang on the page where you put the long code in (follow instructions on page to get the unlock code you'll see what I'm talking about). It is HIGHLY ADVISABLE to do this in Firefox or Chrome (I used Firefox). And yes, you may have to request the code 3x to get it to send to your email depending on their server traffic. When you get it, follow Motorola's instructions for unlocking the bootloader in fastboot. It will show you that the bootloader is unlocked.
Make sure the code you're copying and pasting is correct. If it is incorrect it will not approve you for bootloading unlocking and not tell you the code was missing a letter/number. They are getting sneaky.
***IMPORTANT NOTE ABOUT OEM UNLOCKING GREYED OUT***
If your OEM Unlock tab is greyed out in the Developer Options, just know that Motorola/Lenovo now have some weird timer on that to activate. I had to wait 3 days for mine to activate. Some report it takes longer. Others reported it was 3-4 days. I factory restored, reflashed the firmware, etc. day one just to make sure anything funky that could be put in there was clean and brand spanking new. Not saying you have to do this but there have been varying reports on Moto phones since 2020 about how long this takes. If you're not sure if yours can be bootloader unlocked, get the code from Moto. If it can it will email it to you and from ther ejust wait.
Verizon and ATT Variants CANNOT BE BOOTLOADER UNLOCKED.
***NOTES SO YOU DON'T FREAK OUT***
1. The Command Prompt will tell you it is locked and you will see "flashing unlocked" on the phone in fastboot once it is done.
2. The only way to restore the phone if something goes wrong is by flashing it via fastboot. The way to get to fastboot is turn the phone off and press Volume Down and Power. The Motorola tool will NOT work. That's normal.
3. You will see a cute message that you've unlocked the bootloader and that the phone software integrity is compromised when you boot the phone up every single time after the bootloader unlock. It will also say press the power button to pause. This is normal. Give it a minute, you havent broke it.
4. OEM Unlocking should already be activated and greyed out in the Developer Options once the bootloader is unlocked; you can't access it anymore and it will tell you if the bootloader is unlocked.
Files
You will need an SD card for root. You will also need other apks to successfully help you pull off root ready to install. Pull ALL the necessary files you will need.
1. Get Minimal ADB and Fastboot OR Tiny ADB and Fastboot (it's easier).
2. Download the Motorola Drivers from their site if yo don't already have them (if you run into problems you will have to uninstall and reinstall them through their utility which is found on PC here: C:\Program Files\Common Files\Motorola Shared\Mobile Drivers
3. Cpu-Z.apk (Very important, its hard to know your hardware without this).
4. Magisk v22.0.apk (They no longer have a separate Magisk Manager)
5. Root Explorer.apk (This software helps navigation better but you can use any Explorer of your choice).
6. Root Checker.apk
7. Stock Firmware XT2211-2_MILAN_RETUS_11_RRDE31.Q3-73-12_subsidy-DEFAULT_regulatory-DEFAULT_cid50_R2_CFC.xml (This is important if you mess up the boot image trying to root). You can get the firmware of your choice at Motorola Official Firmware For Milan.
8. Patience (and a good movie keeping you going).
As of now this device as no TWRP, so you have to do this the old fashioned way to root. And just so you know, I used Windows 10 for all of this.
Pre-Rooting
1. Make sure the phone is fully charged.
2. Make sure your sim card is REMOVED from the phone. Everytime you wipe the phone or do anything messing with the boot image the phone resets itself to factory settings, and tries to push an update. Just take the silver key thing and pop it out. You will have to push it back in and out in a second, but start with it out.
3. Make sure your wifi is OFF.
4. Make sure your SD is in and mountable and all files you need are on the card.
5. Make sure you Save boot.img to your SD Card from your firmware files. This is very important for root.
6. Make sure your developer options are activated.
7. Make sure your USB debugging is enabled AND you've given permissions for your computer to have administrative access with it enabled (more on this below).
8. Make sure to check CPU-Z for your hardware specs so you download the right files for the phone and avoid potential problems.
9. Make sure you manually set USB to Transfer files (no other option will work and by default its set to Charge this Device).
10. Make sure you have the STOCK CABLE that comes with the phone. Like most Motorolas this model is funky about using other cables.
11. Make sure you back up all your calls, texts, pics, etc. Flashing the firmware is the ultimate factory reset and you will lose all your files on the phone. SMS Restore is a good software to backup Calls and Text logs and it supports keeping MMS.
12. Make sure you have the internet. It is necessary for some steps.
Rooting
1. Make sure all the firmware files are extracted into your Minimal ADB and Fastboot folder (or whatever ADB folder you're using for this).
2. Open FlashFile.xml in Notepad. This is located among the firmware files you put in the Minimal ADB and Fastboot folder.
3. Cut, copy, and paste everything from the FlashFile that is shown and then paste it in an online Flash file Converter if you are flashing a fresh version of the stock firmware. I used Online Flash File Converter here. I recommend this just in case you're on a newer firmware - if not jump to Step 13.
4. Convert the text by pressing the bar below where you pasted the text. It may be in Spanish or Portuguese but is should say something like Cerar Commandos.
5. Copy the text by hitting the two pieces of paper icon in the corner after it's converted. Or just cut copy and paste manually.
6. Turn the phone completely OFF.
7. Plug your phone via USB cable into the computer.
8. Press Volume Down and Power to boot into fastboot mode. Do not use "adb reboot bootloader" as that command may or may not work and hang at "waiting for device" (it was iffy for me and it knocked off USB permissions BADLY).
9. Open up Minimal ADB and Fastboot (Make sure you don't have it set to open this as an administrator, it messes with permissions) Make sure your firmware files are in the Minimal ADB directory or it won't work.
10. Paste the contents of the flashfile converter into Minimal ADB and Fastboot. This should start the process of the flashing.
11. When the entire flash is complete, boot the phone and disconnect phone from the computer. Ignore the bootloader unlock error.
12. Wait. Sometimes this takes up to 3-5 minutes on a new flash. You should see the boot animation of Motorola.
13. Push your Sim Card back into the phone.
14. Start setting up your device on the screen. Sim Card must be in or it will give you a message your phone is Network Locked.
15. Once you make it to the Wifi Setup screen take the Sim back OUT the phone. Do not connect to Wifi.
16. Once you are done with setup, go to Settings>About phone.
17. Go all the way down to Build Number and press it until you unlock Developer Options.
18. Go to Settings>System>Advanced>Developer Options. Advanced is a pull down tab that will reveal Developer Options.
19. Disable Automatic System Updates. I know this is hard for some people, but a forced OTA update may cause problems and prohibit root.
20. Enable USB Debugging. Disable Verify bytecode of debuggable apps. Disable Verify apps over USB if it is highlighted. Exit.
21. Put your SD/Sim card back into the phone.
22. Go to the Files folder and install Magisk first, then Root Explorer and Root Checker.
23. Open Magisk. You will see Magisk and App. Hit Install by Magisk (a fingerprint looking icon is to its left).
24. Allow Magisk to access photos, media, and files if it asks.
25. Select option "Select and Patch A File."
26. It will take you to a screen where you can select your explorer to navigate to your SD card where you saved the boot.img. Go there and select it.
27. Magisk will save it as magisk_patched.img. Once you get it patched, find where it saved, make sure it's on your SD card and then turn off the phone.
28. Plug your phone via USB cable into the computer.
29. Press Volume Down and Power to boot into fastboot mode.
30. Open up a fresh Minimal ADB and Fastboot (Make sure you don't have it set to open this as an administrator, it messes with permissions) Make sure you transfer the magisk_patched.img that Magisk patched off your SD card into this folder.
31. Rename your original boot.img to "boot.img original" or whatever distinct name you want to give it in your Minimal ADB and Fastboot folder.
32. Rename your magisk_patched.img to boot.img.
33. In Minimal ADB and Fastboot type "fastboot flash boot boot.img" and hit enter.
34. If all goes well it should flash to the partition before it says done and in how many seconds.
35. When it is done, reboot phone by selecting START (keep pressing volume rockers until you see it, then press the power button).
36. Wait for the bootloader cannot be trusted screen to pass (may take a minute) and wait for the Hello Moto opening.
37. Open Root Checker and confirm root. You can uninstall it after confirmation if you like.
38. Open Root Explorer. A prompt asking you to grant permission should pop up.
Congrats. You should be rooted now.
***NOTES SO YOU DON'T FREAK OUT***
1. Do NOT flash someone else's patched boot image. It WILL NOT WORK. Do the work, find your firmware, and patch the boot image yourself. You're asking for bootloop hell if you do as your boot.img that Magisk patches needs to match that particular firmware you used.
2. While it hasn't happened to me, You may have followed everything perfect and it still bootlooped. Save yourself the frustration and just flash it over. See the next section on the proper way to flash so you don't lose your baseband, IMEI, or any other important stuff.
3. While you won't lose anything just flashing boot.img, you will lose everything having to flash ALL the firmware over. Keep backups of all your important stuff.
****Notes on Flashing The Stock Firmware if you have to****
In the event you bootloop and have to start from scratch, follow my guide on restoring the firmware on the phone. And don't worry - it won't relock the bootloader. You can find my guide here: The Complete Noob Guide to Flashing via Fastboot Factory Unlocked Moto 5G Stylus XT2211 [Mediatek Variant]
Hope this helps my fellow TMobile and subdiary acolytes and others. I'll be working on securing R/W access soon.
I will try and answer questions if I can or point you in the right direction.

How To Guide [Unofficial] Unlocking the bootloader, rooting, and installing TWRP on Nokia 2.2 with Android 11

to moderators: this is my first thread ever, and thought a complete guide like this really has to be done. if it's not right or not in the right place, do what is right

Since there are only 3 useful guides about modifying this specific phone, and some really don't answer a few barriers placed in our way by HMD Global and its ridiculous OEM unlocking restrictions (-_-), and also Google probably dropped making OTA updates for it (which was very important to me, because Android 9 and 10 had bugs), I decided to mix them all up (I will give credits, obv) and add some more info I found and create a thread which will work on Android 11, which worked on my phone, not tested on another Nokia 2.2.
Hope it helps y'all!!
Part 0: Preparations
WARNING: Your storage will be wiped completely!! so make sure to back everything you need up before doing anything. Unless you have bricked/soft locked your phone, then in that case you can use MTK Client app to backup userdata.bin (more info on Part 1-2, marked with a )
Requirements:
A good computer
Obviously a network connection on your computer for downloading files, and on your phone if you wanna update thru OTA
USB cable, capable of transferring data, and without any annoying repeated disconnections or "has to be put in the right angle and position". Just use a fresh one
VCOM and adb drivers, which can be a little annoying getting them to work. Best option is to install 15 seconds minimal ADB and make sure you say Yes when it asks if you want to install device drivers.
Android SDK Platform tools, which can be downloaded from here (NOTE: You have to use Platform tools. minimal adb will NOT work with fastboot on this device. So go to C:\adb and delete everything in there, then extract platform tools in that folder instead)
and the most important of them all: MTK Client by Bkerler which can be downloaded from here. Follow the installation instructions in the link, install Git and Python and also usbdk installer featured in the Github instructions for MTK Client
All done? Great! moving to the next part
Part 1: Unlocking the bootloader
The most annoying part. Thanks to hikari_calyx for their awesome guide on how to unlock the bootloader for this phone. We will follow it step by step until we reach step 6, where we are about to flash all those backed up img's back using mtk-su. Here's the problem, you can use mtk-su only on Android 9. it doesn't work on Android 11 sadly. so we just make sure we have unlocked sec1.img and seccfg.img in a safe place, then install a fresh stock Android 9 rom om our phone with any method we are most comfortable with, like SP Flash tool like in the guide, or booting into recovery and sideloading thru adb or from sdcard. just search the net and I'm sure you will find a loooot of sites explaining how you can flash a stock android on your phone. Just make sure you won't mess IMEI and Serial Number up!!!
**There is a "unlock bootloader" option in the flash tools tab of MTK Client. haven't tried it out myself but you can give it a try**
Extra: Booting into stock recovery
There is another detailed guide on how to enter recovery mode, by foobar1123321 which you can see in here. You might need it to apply updates to your phone
After flashing and updating your OS to latest version of Android 11, it's time for Unlocking the bootloader again. but sadly, Unlocked OEM doesn't let OTA updates to be received, and trying to flash sec1.img and seccfg.img on Android 11 is not possible without root, and root is not possible without OEM unlocking :\
So here comes the neat part, MTK Client
Part 1-2: Unlocking the bootloader again
Go to the folder where you installed MTK Client (hopefully you know how git works and got it cloned and working, if no, then read Installation instructions carefully in their Github page), and open a CMD window there by typing in cmd in the address bar. then write python mtk_gui and hit enter. Do not use mtk_gui.bat since it will close the cmd and not work. Do NOT close this cmd tab. After a while, the app will start and asks you to connect your phone.
Shut down the phone, and after 5 seconds, press and hold both volume up and down keys (without the power button) and connect the phone to your computer via cable while still holding the volume buttons. If you have installed the drivers successfully, then you'll see some texts generate in the cmd window, and will (probably) wait for the Preloader VCOM.
you can let go of the volume keys.... but not for so long. Disconnect the USB cable, hold volume keys, and connect the phone again and you'll see that MTK Client successfully gets access to your phon. YAAAY!!
now you can let go of the volume keys
Go to "Read partitions" tab, and select Boot_a, Boot_b, sec1, and seccfg (make sure you wouldn't mistake them with unlocked sec1 and seccfg)
And then click on Read partitions button in the right side, and choose a location to save these partitions
You can also check userdata, if you have bricked/soft locked your phone and wanna backup your Internal storage data. You can flash it again with this app after you have fixed your phone. and if the problem wasn't caused by your data, you can use them again like you never wiped your phone
After everything is backed up, go to "Write partitions" tab, and find sec1 and seccfg, click on "set", browse and select the respective unlocked partitions we got in Part 1 (you may need to change their extension from .img to .bin for them to show up)
Click on "Write partitions", and done! You have unlocked your OEM on Android 11!! and if everything is done correctly, you'll see
Orange state Your device is unlocked and cannot be trusted Your device will boot in 5 seconds...
Click to expand...
Click to collapse
or something like this when powering it on, congrats!!
Part 2: Installing TWRP
from the official TRWP page for Nokia 2.2, download the latest TWRP image file and move it to c:\adb on your computer and rename it to twrp.img
you will also need to download a stock vbmeta image, which can be found here or simply by reading it from your phone via MTK Client (there will be two A/B partitions, any of them works) and rename the downloaded/grabbed file into vbmeta.img and move it to c:\adb
power off your phone, then boot into fastboot by holding Volume down + Power for a few seconds, until it says FASTBOOT MODE => then connect the phone to a PC, and write:
fastboot –disable-verity –disable-verification flash vbmeta vbmeta.img
Click to expand...
Click to collapse
and then
fastboot flash boot twrp.img
Click to expand...
Click to collapse
Now we have the latest TWRP on our Nokia 2.2 , but seems like accessing TWRP is only possible by either rebooting to recovery when the phone is powered on, via Magisk, Termux, or any other app with power options (after rooting the phone), or writing this when the phone is in fastboot mode:
fastboot reboot recovery
Click to expand...
Click to collapse
You can use TWRP and all of its awesome features now, except for MTP, backup, reading userdata partition, etc. to fix that, you gotta wipe internal storage, so make a backup of your files before processing.
**IMPORTANT: Do not flash TWRP after rooting the phone or it will unroot it**
Part 3: Rooting via Magisk
I'm gonna use Magisk because... it's better than other SU apps. Get it from here and install it on your phone. Now that you have your OEM unlocked and boot partitions too, you just have to copy the partitions we got via MTK Client on your device, launch Magisk app, select Install Magisk, then choose a file, which is gonna be Boot_a.
Wait until patching is finished, and after it's done, go into downloads folder and rename it to Boot_a or you will get confused later
After that you can choose Boot_b to be patched, and after it's done, rename it to Boot_b too
Copy them both to C:\adb from your phone to your pc, and power off your phone
after you get sure device is not connected to the computer via cable, and is powered off, hold down the volume down key with power button, until your phone boots into fastboot mode
Now open a cmd in C:\adb, and write
fastboot flash boot_a boot_a.img
fastboot flash boot_b boot_b.img
Click to expand...
Click to collapse
when done, disconnect your device, and restart. You can check the Magisk app, and realize you now have superuser permissions!!!
**UPDATE** Part 3-2: Hiding Magisk
Hiding Magisk and bypassing SafetyNet is another challenging problem on this phone. Cause when you try to Hide the Magisk app, you'll come to a simple "Failed!" error which is most probably caused by SELinux status. To fix this we gotta install some modules
First of all, install Busybox from Google Play or any other source. It's not necessary, but it's good to have. simply just install it, no need to restart
Then we need to install a module called SELinux permissive (wow, how unique ;w; ) by evdenis, which can be found here. download the zip in your phone, open the Magisk app, and in the modules tab browse for our newly downloaded zip and wait until the operation is done. Reboot your phone, and you are now able to hide Magisk app without any problem.
So do so, open Magisk -> settings -> hide the Magisk app. Choose a name (settings by default) and wait until app launches itself, asking you to add a shortcut to your home screen (optional). This way, your Magisk app now has a random package name and signature and can't be detected by other apps. Now moving to the next part
Bypassing the SafetyNet:
First, in Magisk settings, enable Systemless hosts. it will add its module to the modules tab. check if it's enabled
Then toggle Zygisk in Magisk settings, and restart your phone again (2 restarts? alright no problem)
Once your phone booted up, on the main screen of Magisk, check if it says Yes in front of Zygisk. if yes, than congrats! we are not down yet tho
Go to Magisk settings and toggle Enforce DenyList, don't reboot for now (yes, there is a 3rd one coming ), but go to Configure DenyList and choose the following apps
Google Play Service
Google Play Store
Google Service Framework
Google Play Protect Service (which is probably not present, but wrote it just in case it is on your phone)
Click to expand...
Click to collapse
and also you can choose your banking apps, or any app that prevents you from using them like Netflix or some games. Now you gotta restart (third time is the charm )
Now we gotta install another module which is Universal SafetyNet fix by kdrag0n which can be found here. Download it to your phone, choose it in Magisk module browser, wait for it to finish, and restart (I'm losing my control!!! Hmph!)
Now that we did all this, we have to clear data of apps in our DenyList so they would never remember if we ever had root or no
Go to settings (the actual settings, not our now hidden Magisk app) -> Apps -> all apps -> tap the 3 dots on top -> show system apps, then find all the apps you added to your DenyList and clear their data (not cache, data itself)
Now that this is down, restart your phone ((╯°□°)╯︵ ┻━┻) it's the last time, so you can stop raging now (┬─┬ノ( º _ ºノ))
Now we can install an app like YASNAC and run SafetyNet attestation, if the results showed two pass checks, Congratulations, you bypassed SafetyNet!!!
Totally worth the restarts. (Thanks to Droidwin for their article)
And that's it!! Hope you enjoy your now rooted Nokia 2.2 phone with Android 11

Great guide, and yes mtkclients unlock will work but it may put Ur device into verity eio mode

¿Can I use the Part 3-2 to hide Magisk in Android 9 instead of 11?, I find stock Android 11 very laggy and unstable on my phone (using the camera on any app can take from 1 to 3 or 4 tries to get it working, for example), and Android 9 has served me waaaaay better. However, my banking app refuses to work with root.
