iPhone 4 GSM Goes from Searching to No Service - GSM-Forum

Alimaxor · 11-17-2013, 08:20

Hey guys

Recently I replaced my front glass for my iPhone 4 GSM and managed to get a spare CDMA screen from a friend of mine for free. I put it on by actually stripping the GSM plastic rim and putting it on CDMA screen. Screen works, screwed in, back worked (after plying off two of the clips on back screen).

However..... after the whole repair, I found that there is no signal showing up, and it is going from searching to no signal. is this an cellular ANTENNA issue? Wifi works fine, so I am not sure how to fix it...

what is the signal part? I will replace the antenna, but are there any other parts that could have gone bad? maybe the iPhone 4 SIM reader?? which could explain just the cellular reader having issues and not the wifi

The most common problem after a screen replacement is damage in the blue coil near the battery connector. You can find a replacement in ebay or you can put a jumper and your signal is back again. Many guides in the internet...
