Recently, I have problem "waking up" my IPAD 2. It was 5.0.1 jailbroken.
I need to press Power and Home button at the same time for several seconds, then the IPAD will reboot.
Since 2 days ago, I can't wake it up anymore. Always black screen no matter how long we press the buttons.
When I connect to iTunes (v10.6.3.25), it detects the IPAD in recovery mode and it must be restore.
So I tried to restore it by clicking Shift-Restore button, select 5.1.1 ipsw.
It start to restore it (the Apple logo with bar shown on the IPAD) but it failed with Error 28. Always same error after several times retry.
I try with redsn0w 0.9.14b2, it seems to identiy my device as it says Connected: IPad 2 (DFU mode).
It seem my Ipad is stuck in DFU mode.
Any suggestion what should I try next ?
Thanks in Advance
