Relock and return to S-On for Warranty replacement?
I'm on an AT&T Htc one M8 and I have unlocked, rooted and S-Off(With firewater). Tomorrow I will be taking it into the store to swap it out due to a build defect.
So far I have backed up in TWRP, Titanium Backup and copied my SD card onto my computer. I just need to return to S-On and then lock the phone again and return to stock. Can anyone point me on how to do this?
