How to diagnose? iPhone 5s became a total brick
Don't know for sure what happened, but I have an iPhone 5s that is not reacting on normal reset (Home+Power) and not showing any signs of life.
The screen is blank all the time. I left it plugged-in to charging adapter and afterwards to Mac Air for at least 8 hours, but nothing happened. The body of the phone looks ok.
Any ideas how to diagnose?
Is this a good question?
