Need help Going from Cyanogen 6.02 to STOCK

[tw15egan]

Hey guys, rooted my phone the other day, but have been having problems with it so I am going to unroot for a bit. Right now, it is getting hung at the loadup screen, and keeps repeating. How can I get back to stock?

Running cyanogen 6.02, droid incredible
rooted from OTA 2.2
