I had a similar problem: manual searching for networks showed me a the right carrier, but i could not connect.
It was a simple hardware issue, the antenna was not connected.
How i fixed:
Open the backlid, remove the battery and remove all screws. One screw is sealed for warranty reasons. As warranty is very limited i ignored and opened. The plastic frame can easyly be removed, just has some hooks.
On the left side the antenna cable was disconnected from the mainboard. I gently reconnected and reassebled the phone.
After reboot i could see more carriers and i could connect.
