If you are the owner of the LG G3 and live in Canada you can now anytime install the official TWRP custom recovery image on your device by connecting with a computer and using the command prompt. The same guide is up for grabs on all variants. However, each different model numbers comes with a unique file. read the instructions carefully so you don’t make any mistakes. After you have the recovery image installed on the phone you can think about taking a Nandroid backup after you have root access, installing a custom ROM and more.

REQUIREMENTS

The file you find attached in this post is only for the Canadian LG G3 smartphone to install team Win’s custom recovery image. There are numerous other G3 handsets in other countries including the United States, Korea and Europe. Moreover, the United States has several different phone carrier networks all with one variant of the smartphone each. You must only use this file for the Canadian model number. You can check the model number of your device by navigating to Settings > About Device.

BEFORE WE BEGIN

• Don’t start until you have saved at least 50% battery on the phone. We are connecting to the computer for some of the guide. If you choose to unplug from the computer you must make sure the device doesn’t turn off until the flashes finishes.
• Enable the USB Debugging by navigating to Settings . Developer Options > USB Debugging.
• Install the USB drivers for setting up Android SDK from the link below. Likewise, you should have the latest USB drivers for the G3 phone from the official website or by downloading them from third-party links.
• This is an unofficial operation which also voids the manufacturer’s warranty. The handset is still the current flagship under the Lg name. The warranty should still be working if you are running stock Android (plus the bloatware from the manufacturer and carrier network).
