My iPhone 8 did the same thing after I replaced original home button with one from iFix it. So I tried a hard reset, turned the phone off & restarted it…..home button still not working but my phone created a virtual button on the screen that does work!!
While cleaning off the old adhesive the rear housing broke into 3 pieces??!! I was using a kitchen table place mat….I would have appreciated the author giving me a heads up on how fragile the rear cover is.
Great Fix It Guide Adam…..I would only add one suggestion to your instructions. To keep all the iPhone screws organized & separated by size I use a Sharpie marker to color code the screw to the bracket. It worked great! Thanks again!
