iPhone 7 Plus home button not working after baseband chip repair
Hi guys, I got a strange iPhone 7 Plus here. The phone initially has classic audio IC fault. Here is the story:
- I successfully fixed audio IC, but somehow disturbed the baseband chip on the other side of the board, the phone had no service after audio ic repair.
- I asked someone to reballed the big baseband chip for me (as I can’t do baseband). The phone now has service and audio. But it has another problem: the home button doesn’t work (both fingerprint and click).
- I tried new screen. I restored the phone to original factory settings. All made no difference.
The home button worked fine before. It’s not damaged in anyway. If it’s damaged, it won’t work before. When I go to settings, I can see all the fingerprints registered before are still there, which means the phone recognises the home button.
The home button occasionally click and can register fingerprint, but most of time it’s not responding at all when press it.
I want to ask, does repairing the big baseband chip has anything to do with the functionality of the home button? Any help will be highly appreciated. Thanks.
