How to Lock your Bootloader back to LOCKED


 

 

This guide will help you lock your bootloader and have it say LOCKED.  In order to do this you MUST BE S-Off.  If you are still S-On and would like to do this then you need to gain S-Off first.  See my guide for gaining S-Off HERE.

There are few different way to do this. The easiest way is to use the Guru Bootloader Reset Tool. It is simply flashed in recovery.  See HERE.
