Hello, I have found many threads relating to this under M7 sections but I have unsure if they will work on the M8. AT&T is replacing my phone because it has a bad microphone. However, I am already rooted with TWRP and ARHD installed. Can someone guide me in going back to complete stock please? I already have a stock backup and I found a stock recovery. However, I have no idea how to remove the RE-LOCKED logo in the bootloader. As I mentioned before, I found many threads specifically for the M7 on how to do this but none for the M8. Also, I am not s-off.
