Now I am at the point where I:
Root the phone
Go to unlock
enter att sim
and it shows no registered network.
I go to Network operator and select att and it will stay connected for a couple minutes then it disconnects.
Please any ideas?
I rooted unlocked and had my note 3 (original tmobile) working under AT&T. Had the touch screen stop working, so I looked up some causes and people said to reset the phone so I did. That didn't help, later realized the charger port stopped working as well. Got the port fixed and went to use note 3 and it didn't operate as before.
