iPhone stuck in boot loop after repair
So I got a couple of iPhone 7’s in which I replaced the housing, battery and screen to refurbish them.
Upon switching the devices on, both units are going into boot loop.
I’ve tried restoring the device on my mac, but am getting error 9.
I’ve also tried;
Disconnecting camera/proximity sensor
Disconnecting home button
Connecting old screen just incase I got faulty replacements
Is there anything I’m missing? I heard it might be Audio IC, but if the device cant boot at all, this can’t be it, right?
Ist dies eine gute Frage?
