I recently swapped over the phone body for my iphone 7 plus however after completing the swap it does not detect signal at any point, it searches and then just says no signal . I have tried doing a DFU reset and checking all connections on motherboard . Any ideas would be appreciated
there are always grounding connections to the housing assuming you have made all those connections correctly and the housing is good quality the only explanation is possible damage caused during the change. Instead of creating more damage I would take the phone to a decent repair shop ask them to check it for you because otherwise you may cause more damage that cant be repaired.
