Hi repairers, One of my friend tried to change iphone 6 lcd to your friend, He said, if the touch id cable is connecting to logic board, the phone does not turn on. if the cable is disconnected, the phone is turning on. if the phone is turned, and after connect the touch id cable, the phone is freezing with blue screen. He brought to my service. I think its possible long screw damage problem nearest the touch id connector, but I have not very good microscope. Somebody hear similar problem?
Ehhh doesn’t sound like long screw damage. If I had to guess, I’d think it’s the cable on the backplate.. That’s what I’m thinking
