All Android smartphones and tablet come with a stock recovery. It’s in here where you can do vital tasks such as performing a factory reset or flashing official firmware files. If you are planning to root your device and install a custom ROM, custom firmware or anything else that’s unofficial, you must first apply a custom recovery. It’s here that we change the boot process.

REQUIREMENTS

You must have the Verizon version of the LG G3. You can install the same touch recovery system on the other phone carrier networks, but they require a different guide. You can check what model number you have by navigating to Settings > About Device.

BEFORE WE BEGIN

• Installing the Team Win TWRP recovery is an unofficial operation. that means it voids the manufacturer’s warranty. You can gain the warranty once again by revoking the root access which takes away the custom recovery and return the smartphone back to stock recovery.
• We recommend taking a backup of the data. The data you should include in the backup includes call logs, SMS texts, pictures, movies, videos and the phone contacts. You can also backup anything else you think you need.
• Backup using the built-in tool for storing the data. Each device has it’s own unique way of backing up. otherwise, try out a third-party application from the Google Play store. There are some which make copies of numerous things you want all in one hit, or you can install a different app specifically for the task at hand.
• Enable USB Debugging Mode from the Developer Options menu.
• Make sure you have enough battery power to avoid the phone shutting down before the flashing finishes.
