Stuck upgrade on ipad mini 3 to ios 8.3. Upgrade & restore aborted all the time via iTunes on MAC (All latest OS's).
upgrade ipad mini to ios 8.3 is aborted all the time. No possibility to do it OTA, so tried via iTunes on MAC (All latest OS's for iTubes & OSX ). IPad is showing itunes logo with cable screen. Have reset the device but want help.
Am getting error message "an unknown error occured" with variants of codes (39, 5x)
Cannot do factory reset, cannot upgrade ... so am in nomansland !!!!!
Any idea to get a coldstart on this device?
