[T-Mobile LG V10 General] Arr123:
None of the methods in this thread are my own work. I struggled with getting my phone rooted for a long time and spend 10s of hours on the process. I had never rooted before and was therefore unfamiliar with all the terms, unfamiliar with how to complete all the recommended checks to ensure one had the right model, etc. There were several helpful threads but most approach the subject with the assumption that one knows something about the process. In this post I lay out what worked for me in a step-by-step way and what you have to do to achieve my results.

#1 Ensure you have a H-901 motherboard and not the Korean F600 motherboard by checking the sticker, and checking “About Phone” -> “Hardware Info” -> “Model number” in settings. These must both be LG-H901…from what I can tell the community has only developed technique for the H-901 variant.

#2 Get a micro SD card and load it with Magisk https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 , and if you have Marshmallow or Lollipop and want Nougat (much better experience IMHO), load the files in this thread: https://xdaforums.com/tmobile-lg-v10/development/h901-t-mobile-nougat-v30b-twrp-t3639203 And maybe this thread as well (read both and then decide): https://xdaforums.com/tmobile-lg-v10/development/h901-t-mobile-nougat-v30c-flashable-t3744648

#3 Ensure you have unlocked your bootloader. (apparently only for T-mobile LG v10s since other carriers lock the bootloader) The FWUL virtual machine root method will not work if you have not done so. This is an entire process in itself. The following 2 videos which show how to root android 6.0 or earlier (process will not work with Nougat, 7.0, since some fastboot commands are missing). https://youtu.be/OtXlokk6JkQ , https://youtu.be/PPLwFGxLQA4

Also, this thread may be helpful. https://xdaforums.com/tmobile-lg-v10/general/t-mobile-bootloader-factory-unlocked-t3236224 , download the nexus root toolkit here for easy ADB command entry http://www.wugfresh.com/nrt/ —we will only use the “Advanced Utilities” -> ”Manual Input” -> ”Launch CMD Prompt”. When it prompts you to select a phone, select the first option and then for android version select Android *** Any. Don’t use any of the other commands because they are not configured for your device.

If you get a “waiting for device” error while attempting the fastboot oem unlock command in the above thread, see: https://xdaforums.com/tmobile-g4/help/fastboot-waiting-device-t3489789 Great video which shows how to change drivers. You will need to do this, I found a number of drivers that were already on my PC from google and Samsung worked although I didn’t have the specific one mentioned in the above thread. Don’t be afraid to experiment… you can always try another driver. And don’t require it to be hardware compatible. Ignore the warning message: https://youtu.be/nQjg6ePnGAc

---------------------------------------------

NOW that you have your bootloader unlocked you can proceed to actually flash the TWRP image as per this thread: https://xdaforums.com/tmobile-lg-v10/general/root-h901-nougat-t3773942

Notes before beginning:

-To enter download mode to begin: Plug a USB cable into your phone with your phone powered off, hold down on the Vol Up button and plug the USB cord into your computer. It should immediately boot into download mode. Exiting Download mode after flash: pull battery…no damage will be done.

-To enter recovery after flashing TWRP: power off the phone then hold both the down volume and power at the same time. When you see the black LG screen briefly release the power button and then press it again while not letting the volume down up. You will see a screen asking if you want to delete all user settings. Say YES (via the volume and power keys—no touch input). You will see a screen asking if you want to delete all user data. Say YES (the data is only deleted if TWRP loads successfully) You will briefly see the black LG bootup screen. TWRP or factory recovery will load. Or if you did not unlock your bootloader, it will say recovery is corrupted and cannot be trusted, and then boot normally without changing your settings or deleting files.

-Additional note: as of 7-23-18 some commands had changed:

From V20 forum, Brian (runningnak3d) has moved to gitlab.com. So instead of github.com, we have to use a new git repository that Brian created in gitlab.com.

cd

mv lglaf lglaf_BAK

git clone https://gitlab.com/runningnak3d/lglaf

cd lglaf

git pull

git checkout v10-miscwrte

There are additional comments in the thread. Some timeout errors may be solved by: 1 - Download the VirtualBox extension pack: https://download.virtualbox.org/vir..._VirtualBox_Extension_Pack-5.2.8.vbox-extpack

2 - Go to File / Preferences / Extensions / click the + and browse to where you downloaded it.

3 - Once installed, with the VM off, right click on the VM, and go to settings. Click on USB, and pick USB 3.0. If your machine doesn't have a USB 3 port, pick 2.0.

But frankly, simply up arrow after a timeout error to load the last command on the command line and hit enter again. Simply keep doing this until it works. You know it works because no dialog appears for several minutes before informing one of success.

**Upgrade to Nougat after Flashing TWRP and booting to Recovery steps: (I did a full wipe as suggested by this thread: https://xdaforums.com/v20/development/h918-recowvery-unlock-v20-root-shell-t3490594 before flashing the v30b upgrade then full Nougat zip, and then flashing Magisk. I flashed the 3 zips sequentially. I was afraid Nougat would not boot successfully because the zip files are less than 2 gb combined but success! You may want to also flash the 30c upgrade before flashing Magisk for a total of 4 zip flashes. I did not try this. However doing all this means no backups are done so if there is a problem you may have to flash a KDZ with the LG UP tool (don’t ask me how).

As a final note, I cannot answer specific questions about the various processes provided or errors you may encounter that I have not listed in this write up since I have not experienced them. A bit of research on your part may be required, but this post should provide you with a huge head start compared to where I started. Good luck!
