Also, the stock recovery seems broken as it does nothing. I just see the red exclamation point thing, and I swear it used to do something before when I moved the volume buttons.
How do I go back to stock WHILE keeping "tampered" removed? And can I get rid of "unlocked"? I need to return this phone (poor coverage) so I am trying to avoid issues with the carrier.
Anyone have any idea?
soff, unlock bootloader, flash stock rom and recovery, boot into twrp "don't flash recovery" flash supersu in twrp, load system, use soff to remove tampered banner, use soff to relock boot loader so it doesn't say relocked, load supersu and remove root, restore factory settings
