Disabled iPad

I'm trying to restore my daughter's iPad which is disabled and the passcode lost. It's a model A1671, with the Home button. Probably has never been backed up or connected to iTunes, quite possibly never used except to set up with the lost passcode. I've gone through the Restore process at least five times; when it finishes supposedly downloading the software the iPad is still disabled and come back in an hour. It no longer asks for the passcode so I guess it's permanently disabled. Now what?
