Have you been contemplating customizing your LG G4? Although the phone does have some built-in options, you could find yourself running into limitations for what you can change on your own phone. The exception to this is if you are willing to root your LG G4. Rooting comes with many privileges and responsibilities.
If it is done improperly, either by the developer or the user, it can cause problems (some massive) with your phone. But if you stick to trusted sources, find the best rooting resources for your model and carrier, and follow directions, you shouldn’t encounter any problems.
And if for some reason something does go wrong, you can tell us about it in the comments and we will do our best to help you overcome. Then you can enjoy your phone without restrictions, responsibly.
Before We Begin:
- Verify your device model number.
- Realize that rooting voids your warranty.
- Download and install USB drivers on your computer.
- A full backup of your LG G4 should take place before you ever start the rooting process.
Method 1: How to Root LG G4 Using Low Effort Root
The name can be a little misleading, as this isn’t the simplest of methods. This method of rooting is brought to you by a member of XDA, a developer who goes by the name of thecubed.
It is said to root any LG G4, but really, your phone model and carrier needs to be one of the following: T-Mobile H811 10H, VZW VS986 11A, International H815 10C, AT&T H810 10G, or Sprint LS 991 ZV5. Your G4 should also be unencrypted.
Rooting may not even be possible with a locked bootloader.
