My iPhone cannot boot after screen and Front Facing Camera replacement
When I got this iPhone 6 Plus, its screen was badly cracked. I ordered a new screen and replaced it, it could be booted normally at that time, but I noticed that the front facing camera and earpiece speaker did not work normally. Hence, I ordered a new "iPhone 6 Plus Front Facing Camera and Sensor Assembly Replacement" and replaced it, but now my iPhone cannot boot. It keeps rebooting after showing the apple icon. Please refer to the following video:
I have tried the following methods:
1. I used the old facing camera and the new screen, but the problem still exists. It is weird, as I can boot it normally before installing the new facing camera.
2. I used the old cracked screen, no facing camera connected. The problem still exists.
3. I used the new screen, no facing camera connected. The problem still exists.
Do I damage the mainboard when I was installing the front facing camera? What should I do next? Please help me!!!
UPDATE: Well, after restoring my iPhone 6 Plus using iTunes, the iPhone 6 Plus can boot now, but the digitizer is not working. When I use my fingers to touch the screen, the screen does not respond. ....
Is this a good question?
