How to access Recover Mode after selecting Update rather than Restore during reset?

Looked like I screwed things up on my iPad badly. My iPad no longer recognized my passcode (I know it was right since I use my iPad many times daily) and became disabled. I followed the instructions for the factory reset, however, I selected update rather than restore in hopes that it would purge the password and get me back in. The result, my iPad is still disabled, holding the sleep/wake button no longer exposes the slide to power off the iPad, and holding down the home button does not get me back to recovery mode. Any suggestions would be greatly appreciated!
