What if this doesn't work? Do you have any suggestions? My iPhone 6s just randomly shut off yesterday, and I've tried hard resets, iTunes, and contacting Apple Support. Neither of the first two options made any changes to my black screen, and the latter just resulted in Apple telling me to try those methods again, and when those didn't work, to schedule an appointment w/ the Genius Bar to repair my screen. That's my last resort. I know this is an old thread, but it's still working for people today so I was wondering if there was anything I could do next.
If anyone else with the same problem (or prior experience) has any suggestions, please reply. Thank you.
