Configurator is 'Unable to Update iOS". Error 11 (Preflight options copy fail)
I'm attempting to restore 720 iPads to factory settings, and place a Configurator profile on them.
I'm using a Bretford Cart that holds up to 30.
Everytime I run configurator, it's unable to update iOS, and it specifically says that It "failed to copy preflight options during recovery mode restore. Error 11."
Half of them work, and are done correctly, and the other half give the error.
Some of the iPads are on iOS 5, I'm sure, considering the amount of iPads that I'm dealing with. Could this be the issue?
What am I doing wrong?
MacBook Pro, Mac OS X (10.6.8)
