No service after LCD replacement. Constantly searches
Hi everyone. I recently changed the LCD on my iphone 4S. I took a lot of care when doing this and the logic board seems to be in great condition with everything else working, inlcluding the speakers, touch screen and wifi. But I can not get any signal from the sim card even though the iphone can register the sim card details, and says no sim card installed when I take it out.
I have tried a lot of the solutions people have suggested on here. I have cleaned all the metal contacts with alcohol, made sure the connectors are properly connected (well atleast I think they are) and even bought a new antenna, a new chassis, but nothing seems to have worked.
Im really racking my head over this now, can someone please give me some advice about what to do. Should I get rid of the phone or try resetting it again. Connect it to Itunes and restore again.
Ive realised the emergency call didnt work, so would that suggest it is an antenna issue??
Any help at this point would be really greatful.
