The unofficial TWRP recovery is a must on the LG G3 smartphone for all people looking to customize their devices with a custom recovery or firmware. There are two main sides to Android smartphones: stock official Android and those who open up the OS with root access. If you are wanting the latter you must install a custom recovery image to go with your custom ROM.

Both sets of recovery images are amazing, but the custom version does a lot more than just create a bootable partition for installing firmware and taking a factory reset. With the custom variant we can take a Nandroid backup of the OS, flashing zip files from the SD card and other operations.

The following only applies for the Sprint variant of the LG G3. It’s available for a few different phone carrier network in the United States, and many more across the globe. Do not flash the file in this post for any model that isn’t from Sprint. You can check your model number by navigating to Settings > About Phone.
