Jailbroke iPad 1 4.2.1 with redsn0w -- won't boot up after jailbreak

[hpcomputergeek]

Please help me, I need help with this. This happened after I jailbroke it and it won't boot. It just sticks at the Apple logo with a spinning wheel.

This is a friend's iPad so I need help ASAP.

Try turning it off, holding the volume up button then turning it back on. You can also try putting it into dfu mode and using redsn0w/tiny umbrella to kick it out.
