Note : Put it to DFU Mode while connected to computer and also in DFU Mode your iPad will remain blank. Timing is critical when you put it to DFU Mode, so keep trying until it goes to DFU Mode.
If you don't have iTunes application installed on your computer, download and install it from here : http://www.apple.com/itunes/download/
I posted a further request on this earlier, but didn't hear back from you. I haven't been able to try your response because my ipad screen had a message ... something like "The device has been disabled." The screen went black, and I haven't been able to turn the ipad back on. Any suggestions?
