I've just replaced the screen on my Nexus 5 myself, however having searched through this forum for an answer to my problem I'm left kicking myself and wish I'd just sent it to LG as per many recommendations.
The replacement seems to have been quite successful, everything works, apart from I now have 'No Service'. I've removed and inserted the SIM and the phone recognises that a SIM card has been inserted but will only allow Emergency Calls to be made.
Its all been to bits again and put on to the old screen, the problem remains. Very frustrating.
I don't suppose anyone might be able to help me diagnose the problem?
