iPhone constantly searching for signal and end up with No Signal
I have opened my iPhone 3GS to replace battery. I am not sure what was the damage I have done to my phone. After reassembly, it's searching for signal and finally says no signal. I gave the phone to local repair shop, they have tried changing the doc connector from a working phone but still no luck. I have made the small copper tooth near connector 7 touching the silver frame. Still no luck. I suspect connector 7 on the mother board is damaged. I have attached my mother board pics here. http://www.flickr.com/photos/79479917@N0...
Has anyone faced this issue and replacing connector 7 male connector in the board will solve the issue?
Is this a good question?
