i repaired my phone with a new motherboard and im having boot issues. its keeps saying : SECURE FAIL: RECOVERY system software not authorized by AT&T has been found on your phone. please turn off your phone and go to the nearest AT&T store for help. How do i fix this issue?
Hi you will need to use odin to reflash the stock firmware for your device. I would suggest using xda as a point of reference.
