The official Team Win TWRP custom recovery is up for grabs for most LG G3 smartphones. It’s available across several phone carrier networks in the United States and there’s also an International model number. If you own the International variant you should apply the following steps to equip your handset with the custom recovery image. Only then are you able to flash custom ROMs, take a Nandroid backup of the current ROM, install custom firmware and perform  several other tasks thanks to the new bootable partition.

The official TWRP system represents the Touch Wiz version of the popular ClockworkMod recovery (CWM). Some people prefer one while others prefer the other. Often you go with whatever is readily available and easier to install.

REQUIREMENTS

BEFORE WE BEGIN

• Backup the phone contacts by using your preferred method. The helium app for Android is great for contacts. It’s a third-party application available from Google Play.
• You must enable USB Debugging Mode from the Developer Options menu to connect the phone to the computer. That’s a must since we are using Android SDK with ADB and fastboot.
• Disable any antivirus and anti malware programs that are running on the Windows computer. Furthermore, disable the security apps from the phone.
• Installing a custom recovery image is an unofficial operation which is not permitted by Google or LG. That means the warranty is immediately void after applying the image below.
