Chosen Solution

I replaced the screen, only for it to not get any touch signals. I then put on the old one and same issue. I have since updated the firmware and still cannot find a solution. Any tips?

Specifically with iOS 11 it is extra important that the battery is unplugged when any cables are being detached. I would try to clip in the new part (battery unplugged) then plug in the battery and do a soft reset. If that doesn’t work unplug battery and plug in original and try again. If that part is still the same then it is possible that the pins on the motherboard where your digitizer ribbon connect may be damaged. Let me know if that works though
