IPhone 3GS



the Phone is blackout but still receiving calls.

reboot with 'power'+'home' buttons, the screen displays icons but very dark and can hardly see it. I checked brightness: auto mode is on.


Any help is much appreciated.

    sync the iPhone and then reset it from within iTunes, which restores it to original factory settings

    In order to fix KERNAL PANIC... force the iPhone handset into DFU mode (recovery mode)...


    1. Force device shutdown.... by holding the power and home button.

    2. Now hold down the home button for 10 seconds and then still holding the home button connect the iphone to the computer, release home when you see the itunes symbol or after around 10 further seconds.

    3. At this stage you can connect it to iTunes and then do a factory restore.
