My phone had been working fine for a while. Today I decided to check and see if phone was unlocked so I popped in a t-mobile sim. When I turned the phone on it wouldn't go past ATT logo. Anybody ever have this happen?.

This happened to me with the Tmobile logo. I had to hold down the power button until the phone restarts.

It turns out that the guy who provided a service for me recenter had rooted my phone. Had no idea. Well he offered to revert back to stock for me. But on the smart switch app it asks for the serial number...that might need to be new thead of its own
