iPhone 5 hanged and now cannot be entered Was using Chrome and WhatsApp on my iPhone 5 when the two apps hanged. Since I was unable to activate multitasking, such as to restart those apps, I tried to lock the phone. However, upon locking my phone, I was unable to unlock the phone. The phone is still switched on, since I can still activate Siri, but the lock screen is pitch black, so I am unable to access my passcode lock screen to unlock the phone. Essentially, my phone is switched on, but is effectively a brick. I am unable to do a hard reset on my phone, since my switch does not work (as a result of being used too often, the wire in the switch has come out of place and renders the switch obsolete).

I connected my phone to my MacBook Air so as to backup and then restore the phone, but the backup has failed a few times, so I cannot restore the phone yet. Does anybody know how I can troubleshoot my phone to get it working properly again?
Drain your phone battery to 0% by leaving it on its own (or as suggested, play music using Siri or make a phone call that you can leave running, if that's possible).
