I have the same problem, and I know now that I misplaced the screen shield screws, because I had the bluescreen issue, but put screws back where they belong and seemed to work fine except for the home button. Finger scanner works, but not the home button. Are there any traces on motherboard under that screen screw that is related to home button or am I chasing my tail here. Tried reconnecting xx amount of times to no good. Tried swapping home button to no use , then the finger scanner died too ofcourse so put stock home button back so at least the scanner is working now. Should I go aheadand change the Lightning dock connector that home buttons connect too, or do you guys think its related to motherboard trace issues??
