No service after changing screen
I have an iPhone 5 and recently I decided to changed my screen. So I took the old screen and replaced it with a new screen (camera, per-assembled). Then I put it back together. Everything was going perfectly fine, the new screen was great. Then I noticed that my phone has no service.
Things I've tried:
Resetting network settings
Hard power reset
making sure all cables are good inside
connecting to itunes
connecting to wifi
Nothing has worked, can you please help me.
