Chosen Solution
I have a IP7 with no Touch ID or home button working. I changed for a JC home button yet I get no response with single click/return to home or long press. There is also no response through home button settings. The only response I get is from double click with half screen. I tried another JC home but still have the same problem. The buttons work ok in another IP7. I did get a message flash up once that the home button needs servicing as I was tired and dumb enough to leave the battery connected but haven’t seen that since. I tried a dfu restore through iTunes. Could I rollback IOS through 3utools? Would this help? Any help guys please as I’m baffled
There may be some damage to the screen, specifically the flex that runs underneath the heat shield and connects the actual Home button to the logic board. Seeing as how you have two devices, try the working screen/Home button combo on the first device to see if that solves the problem.
