iPhone was thrown, it's bent. No sim detected, searching...

Hi there. My friend threw his iphone in a nerve attack. The meal frame got bent and the screen would be detached on the front part from the frame.

The phone would turn on, but would not ask for a pin or detect was a card, just a message that told the iphone should be restored.

I disassembled, turned the frame back to original and assembled it again (the motherboard was quite bent).

After putting all together and restoring it to 7.1. the phone will still show the same symptoms. I'm not able to activate it since itunes says there is no SIM installed.

I changed the antenna from an spare and still no signal....

I read about the coil thats by the antenna connector and its there. I guess one of the copper tracks from the motherboard must be cut by the bent.

Do you guys have any other ideas?
