How to Unlock Bootloader, Install TWRP & Root LG V20

As the rooting process is quite lengthy, we broke into parts for easier understanding. Follow the process carefully and try reading the entire tutorial before getting into the real business. So, here we go!!!

Unlock the Bootloader

  1. Download the “V20 root files” zip and extract it in your active ADB directory. Also, download the TWRP image and paste it in the same location. Copy the SuperSU zip to SDcard.
  2. Connect your device to PC and verify is ADB is working or not. You can do this by executing the below command.
    adb devices

    You should see your device ID number on the screen if the connectivity is good.

  3. Double click the “RUNMEFIRST.bat” file on your PC and don’t close the log window that opens. Now, double-click the “Step1.bat.”
    Note: You will get a permission denied error for 2 files: Flatland and Flatland64. This is normal, do not worry about it.
  4. Once you get a shell prompt on the Step1.bat command window, type the following commands:
    run-as con
    chmod 0777 /storage/emulated/0/*
  5. At this point, open the terminal emulator app on your phone and type “id” and press enter. You should see context parameter as “Untrusted_app.”
    If you don’t see “Untrusted_app” in this step, repeat the process from Step 1.
  6. In terminal emulator, type the below command. Make sure you type the entire command correctly and hit enter.
    applypatch /system/bin/atd /storage/emulated/0/dirtysanta
  7. Monitor the RUNMEFIRST window for when it tells you to run Step2.bat file. When it tells, just double-click the “Step2.bat” file.
  8. Once the Step2.bat is completed, you’ll be in bootloader with an unlocked bootloader.

Note: The device vibrator might constantly buzz for the Verizon users till the end of the process. Don’t worry; it’s an expected thing during the process.

TWRP Installation & Root

  1. Double-click on the “Step3.bat” file so that the TWRP and a working boot.img is flashed to your device.
    Note: If you see a message, “<waiting for device>,” you need to install the fastboot drivers on your PC first.
  2. Your device will boot into Android OS now. Type the below command to put your device into recovery mode.
    adb reboot recovery
  3. [Sprint Users only] Sprint users will have a constant app crash. So, you need to go back to bootloader mode by removing & reinserting battery, then press “Volume Down” button while plugging the phone into your PC. In a command prompt, type the below commands:
    fastboot erase system
    fastboot reboot

    Your device will reboot to an LG screen. Keep checking for ADB connection using “adb devices” command. Then type the below command to go into recovery.

    adb reboot recovery

  1. [Verizon Users] If your device takes abnormally long time to boot, get into bootloader mode and use the below commands to flash the boot image:
    fastboot flash boot boot2.img
    fastboot reboot
  2. [All variants] If you encounter a “Secure boot password” at first boot, you didn’t format data properly. So, back to recovery mode and format data once again to decrypt your device.
  3. Once your device boots, get it back to bootloader mode and use the below commands to flash the boot image to fix battery drain and random app crashes. You will need to enable USB debugging once again.
