I’ve repaired several iPhone 7 Plus devices. About 50% of the time, the phone gets stuck on Apple logo after repair is done. I’ve read a few threads on this issue and there seems to a broad opinion on what may be the issue. I always thought it may be hardware issue but I am ruling that out on this most recent device. Any other thoughts?
Common causes of stuck on apple logo or takes like 5 minutes to boot:
- Audio IC going bad, this will cause it to get stuck on apple logo indefinitely or not being able to do a voice memo recording.
- Home button or Front camera ribbon cable damaged. Damaged Home button will cause it to take a long time to boot. To rule out front camera simply leave it unplugged and keep Home button plugged in to turn on.
Almost always in my experience it has something to do with the front camera proximity cable. The hold up at the Apple screen is due to the proximity sensor being blocked by something or the leads on prox weren’t covered back up by the little black plastic cover that comes off when your pulling the prox off. It’s very easy to miss but seems as though it is needed to not allowing the leads on the prox not to touch the back of the phone directly.
I’m having the same problem, brought a complete screen apart from the home button , so it had the speaker, camera and prox already fitted, works fine with the top ribbon disconnected but as soon as the ribbon is connected it stops the home button working and won’t boot up
