I had exactly the same problem about 3 hours ago. Here is the way I resolved the problem (by entering DFU Mode):
- Hold the Power button for 3 seconds
- Hold the Home button without releasing the Power button for 10 seconds
- Then the Apple Logo appears, and everything works as usual
didnt work at all guys. help me on this, is there any other tips to solve this kind of problem?
Something similar happened to me! I wanted to update my phone so I did, next time I look at my phone its completely black. I press the sleep button and the home button at the same time and separetly, I try charging my phone for 20 minutes and nothing happens! I am currently on itunes, restarting my phone! I hope it works and all my data isnt erased! does anyone know what happened exaclty?
