How to Unroot LG G3

If you are one of those adventurous mobile owner and you’ve performed various custom operations such as tweaks, then your phone must’ve gone through a rooting procedure. After this customization, you are allowed deeper-level access rights and controls. This customization usually causes your internal system to be unlocked and open for lots of tweaks. This means that all of the factory default restrictions will be left to your control and you call the shots.

What is the Process?

If you get bricked, the technical assistance to get it to work properly again could be costly since the company will not be liable because you do not have warranty anymore. So, in order for you to get your warranty back, you’ll have to unroot.

By doing this, you will be able to reinstall all the factory default restrictions that were made available to you and this will bring back your phone to its original state – including the warranty.

What You Need

To complete this, you will need a PC or a laptop to download certain files that are needed for the procedure and for your phone to establish a connection where it can access the downloaded files. You will also need to disable your antivirus and other security protection programs so that it will not interfere with the process.

Make sure that you also has enough battery life that could last the whole downgrading session (fully charged battery would be great!). If you get turned off during the process, it could get bricked and that would become another problem for you.
