Hi all, I am preparing to give my G2 to a family friend however I currently have it rooted with TWRP custom recovery installed. As I want to give it to them as if it were new, I need to restore the phone to its original state i.e. 4.2.2 stock jellybean, without root or TWRP installed. I currently am on stock 4.2.2 and have not flashed any roms. How would I unroot and remove TWRP? Thank you in advance for your help
