If it's showing the 'disabled' screen then it needs to be connected to a computer's iTunes. If it's not the computer that it's normally synced to, then, from http://support.apple.com/kb/HT1212 :
If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present.
You may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808
this feature is just well... PLAIN CRAZY!!!
I went on a 3 hour journey on rough roads with my bluetooth keyboard in the back and the ipad. It appears that the bluetooth keyboard was hitting the ipad for the security code that the ipad was locked. I totally wasted my intention to go somewhere quiet and read and write on the ipad. Seriously pi$$d with Apple putting this into the coding i returned specially to try and contact Apple and unlock the system. FOUR chat sessions later going to the next day as well it was settled that i had to restore my computer as i am travelling and have no access to another persons computer given that i am dependent on my own computer to RESTOREthe ipad for which a RESTORATION could not be successfully performed...
"oh thats weird .. can you try it on another computer" was my suggested fix. SORRY ummm no im travelling overseas!! .. so it makes me wonder whether to travel with another apple product again as if something happens or you discover some crazy feature that puts you into a compromised position when out on the road ...sorry you got no help.
I have also the same problem but mine is not synced to itunes on any computer so I can't sync with my Ipad.I read that apple "find my Iphone" can be used to erase the passcode on the disabled Ipad and now sync the Ipad to itunes.My big problem is when I was erasing the passcode,It says that the "disabled Ipad" is connectiong to the internet but it doesn't connect,I waited so long but it didn't connect to the internet. Please help me,My Ipad is for my education
Remote wiping doesnt work in all cases. It didnt for me.
This is just a stupid function where I had my ipad lockup and had to wipe something but I dont keep data on the unit its remotely stored ... but at least im not as flipant as you to say .. yea go ahead.. wipe your system .. f#@k your data and what it means to you because of Apples stupid lockup programming.
Apple at one stage couldnt do a thing other than to send it in for servicing (which is to another country). That would have meant the unit away 5 weeks checking out why it couldnt be remotely wiped, couldnt be locally wiped etc. It just so happened a remote wipe worked after many many tries.
Its caught me out and should be changed.
