"iPad is disabled, connect to iTunes"
I heard that Jailbreaking it may work, it's probably your only option to salvage the data on the iPad. Normally, I would never even suggest Jailbreaking, but in this case, it's probably your only option. I've never done it and have no interest whatsoever in Jailbreaking, so I can't tell how to do it, what to use, or even if it will for sure work, but it's worth a try.
