LG recently released the official process for unlocking the bootloader for it’s latest LG G4 smartphone. LG despises people unlocking their phone and running custom software which is why we still haven’t seen an official tool for last year’s LG G3. Anyways, it is here now and we will guide you how you can easily unlock the bootloader on the LG G4. Do note that this currently works for the unlocked LG G4 with H815 model number.
As you continue reading below, we will guide you on how to unlock LG G4 bootloader for installing custom ROMs, a custom recovery or doing anything nasty with your phone — most of all, you will be able to root LG G4 on Android 5.0 Lollipop and enjoy the various root apps. Just to be clear, unlocking bootloader will wipe ALL your data form the phone. So make sure you backup everything or unlock bootloader on a new device with nothing to lose.

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean and KitKat.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
5. [IMPORTANT] Copy all the backup files from your SD card to your computer as internal memory will be wiped clean while unlocking the bootloader.

If you are a developer and would want to unlock the bootloader, we recommend doing that before you set up the Google Play Store, install apps or anything because the security feature in Android clears out everything from your phone when unlocking bootloader of a phone.
