iPad 2 is bricked from iOS 9
I attempted to upgrade to iOS 9 today on my iPad2 and have been unable to complete the process. The first issue was getting stuck on the slide to upgrade screen, and getting no response from the slide gesture. After resetting, I was able to slide and a black Apple logo appeared with a grey/black progress bar. The bar fills up to about a third, before going back to the slide to upgrade screen. I am stuck in this loop. I have tried to reboot the device in recovery mode by holding the power and home buttons down, but the device just restarts back to the dreaded slide to upgrade screen. I have also connected to my PC and iTunes, but I get a prompt 'To allow access, please respond on your iPad', but again, all I have is the slide to upgrade screen. There must be some way to get out of this loop, as it is at least a soft brick. Does anyone have any suggestions?
