How to Root LG V20! [AT&T/Sprint/Verizon/Korean]

howto-root-lgv20

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.

This tutorial is based on the original tutorial on XDA but I will be using Windows computer.  If you are using Mac or Linux, please follow the original instructions here.

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.

      Keep calm man. This takes a little time to perform. Take care first of the file root in your computer. Not to offend, but are you familiariced with the C:/ language?

  9. Vepa says:

    Hey your TWRP link just leads to the v20-root.zip file. You already have a link for that once, so I’m sure it was a mistake.

  10. Hengki says:

    How about LG V20 F800S (10t) ..is it works?

  11. BlackH2O says:

    @ Vepa, you’re right, the link to TWRP is wrong. The link for it can be found here:

  15. Steve says:

    When I use terminal emulator and plug in the command,”applypatch /system/bin/atd /storage/emulated/0/dirtysanta”(by the way, is there a space after “atd” ?) Anywho, I don’t think that command is working and after I run step 2 and it reboots, it does NOT go into fastmode. Anyone have any ideas ? Hopefully it’s something simple. Thanks !
