In this MASSIVE tutorial, I will be showing you how to root the LG V20, this root guide is specifically for the AT&T H910, Sprint LS997, Verizon VS995, and Korean F800L models ONLY! If you do not have one of these models, please DO NOT FOLLOW THIS TUTORIAL! For T-Mobile and other variants, check this page on XDA.
Also, this root method involves unlocking the bootloader using DirtySanta method, meaning you will LOSE EVERYTHING and there is no way to REVERSE the process yet. Once rooted, you will be stuck with a rooted device. However, rooting will give you the ability to enjoy custom ROMs, which I feel are better than stock anyways.
Step 1. Go into Settings->Software Info and tap on “Build number” a bunch of times until it says developer mode has been turned on.
Step 2. Hit the back button twice and you will see a new menu called “Developer options”, tap on that and enable both “OEM Unlock” and “USB debugging”. If you don’t see “OEM Unlock” option, just make sure “USB debugging” is checked on.
Step 3. Download the following files and unzip fastboot.zip, usb_driver.zip, v20-root.zip.
Download Sprint Stock ROM for Sprint LG V20 ONLY!!!
Step 4. Copy the SuperSU zip file to microSD card then put the microSD card on your LG V20. For Sprint LG V20, also copy over the Sprint stock ROM.
Step 5. Install the LG drivers.
After installation, you should see “LGE Mobile for ADB Interface” in Device Manager.
