Update iPad2 from IOS4.3.5
We have several iPad2 at work that not have been updated since Ios 4.3
We are now not able to update either of them to either IOS 9.01 or any other IOS. We get the same error on each ipad (unkwn error 9) and we are getting stucked into recovery mode. We've tried "every" possible way, tried useing IOS9, IOS8, IOS7 instead, tried deleting everything on the ipad, but nothing helps.
We have aprox 10 ipads With this problem so we really would like to get this fixed!
iPad 2, iOS 4.3.3
