Unlock LG G3 and Install Custom TWRP Recovery Using Bump (All Variants)

In this tutorial, we will show you how to unlock your LG G3 and install custom TWRP recovery on it using Bump. Bump is a bootloader unlock tool that lets you unlock your LG G3 letting you flash anything that has been “Bump’d”, including the TWRP recovery image. This “Bump’d” method supports all variants of LG G3.

LG-G3

Unlocked LG G3 with custom TWRP recovery provides a number of features over and above the stock recovery such as backup &restores firmware, flash custom ROMs and applies various tweaks. The “Bump’d” TWRP recovery supports all variants of LG G3 such as D855, D852, D850, F400, D851, D852G, LS 990 and VS985.

Before you get started, please note that Bump does not actually unlock your LG G3’s bootloader; it gains the process in a similar way. You can flash Bump’d images (here TWRP recovery image) on your LG G3 easily via ADB or via Flashify app with root access.
