Install the firmware that was on it before you tried to root and start again. Read the guides carefully and ensure they are upto date.So I have a Samsung Galaxy s7 930T I was trying to root/custom rom it so I can have 930U firmware. I kept getting failed in Odin I assume because im getting the error "check fail : recovery" in bootloader. I did OEM Unlock, the phone is unlocked it self. So I tried to do multiple things and now the only thing thats happening to the phone is its stuck on "System updating" then turns off and goes back to that screen on a loop. Please help
I cant seem to find an actual guide to help me fix these errors I been having, I am doing it to the T I do know that but I keep getting Odin failures when trying to do anything and I feel its cause my Bootloader is locked I just dont know how to unlock the boot loader. I did OEM unlock, tried to do that .img thing but that keeps failing so now im stuck lol
You can't unlock the bootloader on the 930T, you can only root it. Maybe try flashing the current T mobile firmware in Odin to get your phone up and running again.
