iPhone stuck in boot loop when front camera is connected
I fixed the broken camera lens of my brothers iphone 7. I opened the phone and unplugged the back camera. Removed the lens and replaced it with a new one. I didn’t remove the screen assembly. So far so good. After putting the camera back and closing the phone it kept showing the Apple logo and turning off. Endlessly.
After hours of frustration I noticed the phone would boot correctly by unplugging the front facing camera ribbon. So I turned it off again and connected the ribbon to be sure. And yet again the phone got stuck in a boot loop. I Unplugged the front facing camera flex cable and got it running again..
I did not touch this connector with the repair. And I was very careful. I fixed a lot of iPhones but this seems very strange to me. I can’t find the problem.
With the phone on I noticed the 3D Touch and home button/Touch ID are also not working. This is a different ribbon cable to my knowledge and too much of a coincidence. Also a connection that’s untouched by me or anyone else. Can someone point me in the right direction? I don’t know where to go from here.
Many thanks! :)
Is this a good question?
