hey I got an iphone 7 plus with broken back camera, I tested it and the back camera and front did not work. I replaced the back camera and non of the cameras work still.. Is it because the front camera is destroyed aswell?
I suspect that this is a logic board issue, specifically a power issue. Either the PMIC is not outputting the proper voltages for the cameras or there is an issue with the associated circuitry (filters) or downstream Boost converters for Utah/Nevada. This would require a micro-soldering repair.
There might be, depending on how bad your damage is, that you might have damaged the connectors on the logicboard? havent really had any chances to look inside the new Iphone 7, but i would think the connector is probably damaged, or something? :) Good luck, hope i was for some help :)
