I plugged my mini in to charge and left it downloading the 6.1 update - I woke the next morning to find an unresponsive iPad.
If I power it up the charge symbol appears, I've occasionally seen the apple logo after a hard reset but thats all.
I've followed the steps to attempt recovery multiple times and the connect to iTunes appeared once - at which point I left the iPad for 4 hours while it downloaded the software.
The download completed but my iPad was not restored.
My iPad appears to be charging but then when I hard reboot it I'm back to the charge symbol, implying it has no battery life.
THat one stage when I got to the 'connect to iTunes' and followed the restoration steps seems to have only compounded my problems with the iPad.
As I type, the iPad is displaying the apple logo but not booting, and isn't seen by iTunes.
Any help would be appreciated at this point...
See if anything here helps... Frozen or unresponsive iPad.
