An unknown error occurred 56
Hi,
I was try update my Ipad Air 2 from IOS 8.1.1 to IOS 8.1.2, for some reason it stop middle of updating process. Then the ipad display connect to iTunes screen. Now I try to restore/update the ipad with iTunes, but at the end process iTunes always show "An unknown error occurred (56)", ipad screen stuck at progress bar screen. Tried with different computers, usb ports, firewall disable, anti virus application disable still no luck. Chat with support, he recommend bring to nearest authorized store which is 200KM away. Now the ipad is completely unusable. Does anyone facing same problem?
iPad Air, iOS 8.1.2
