iPhone cant find network after fall.
Hi, my friend smashed his iPhone and wanted me to repair it for him as I have done it multiple times before. When I removed the back cover I found out that the antenna and battery cables are ripped off, so I have replaced both of them. The battery works fine, but the phone was keeping searching for network. I thought that maybe it was the after market antenna so I replaced it with one from an working iPhone (and put the aftermarket one in it and it worked fine, so no problem here) and it was still searching, therefore I started to think its a software fault. While connected to my wifi, I have checked if the date sets automatically, tried cycling the air plane mode, then restored the network settings, then the phone, then updated to iOS 7.1 and it still keeps on searching.

This is the best picture i can take now, if anyone is still interested in solving this case i would be more than happy to take more pictures of the area
Is this a good question?
