No service after battery change.
I recently replaced the original iPhone 5 battery with a new, golden, high capacity battery from dx.com. Upon switching the iPhone on, the phone would just say searching in the top left corner. There were no request for putting in the SIM code or anythin, it just did not want to find the SIM card. I tried ejecting the tray and putting it back in again, but nothing happens. During the repair I did not remove the digitizer and LCD. Please help?
