The LG V20 which is the Korean manufacturer’s latest flagship phone, amid rumors of yet another LG G6 phone, has now received the most awaited rooting guide. The guide provides us with an exploit to first unlock the bootloader using various patches and batch files, then setup TWRP and ultimately flash the latest SuperSU 2.79 for root access. XDA member me2151 has come up with a DirtySanta Bootloader unlock and Root guide for most of the LG V20 variants including Sprint LS997, Verizon VS995, AT&T H910, Korean F800L. The T-Mobile H918 LG V20 variant has a simple root method as listed below.

Before you proceed, there is something you need to know. This is an exploit and may not prove to be stable with all of the V20 devices. There are some issues with this rooting method which are listed below. Also, international variant H990DS may receive support in the future.

Installation Instructions

Step 1: Make sure you setup ADB and Fastboot on your PC, Mac or Linux machine.

Step 2: Download and transfer all the files from above to your PC or wherever the ADB is installed. Also, extract the “v20-root” folder. Copy twrp-3.0.2-1-us996.img to ADB directory as well.

Step 3: Connect your Android device to the PC and trust the connection- tap Yes on “Always allow from this computer” when you plug in the device into PC for the first time.

For Windows, run the “RUNMEFIRST.bat file and do not close the log window that’s shown. Now, run the “Step1.bat” For Linux/MacOS run the files RUNMEFIRST.sh and Step1.sh.

Note: You may get a permission denied error when you run the above files: Flatland and Flatland64. Ignore it and proceed.

Step 4: Next, you will get a shell prompt on the Step1.bat command window, issue the following commands:

run-as con
chmod 0777 /storage/emulated/0/*

Step 5: On your LG V20, launch the Terminal emulator app and enter the following code:

id

Step 6: You shall receive context=u:r:untrusted_app. If it does not show the untrusted_app context, start over the process.

Step 7: Now issue the following code in the Terminal Emulator:

applypatch /system/bin/atd /storage/emulated/0/dirtysanta

Step 8: Take a look at the RUNMEFIRST dialog. When it tells you to run Step2, run it. On Windows, double-click “Step2.bat” and Linux Step2.sh.

When the Step2.bat file has completed the operation, the bootloader is unlocked. Its time to install TWRP recovery.
