The SBF will return you to stock..."out of the box" set up. Just curious....have you tried to download either the TBH Triple threat.....or ROM manager? ROM manager I believe installs a new Clockworkmod which might help you. Also....I didn't read all of this as I am at work but did you reinstall Droid Bootstrap? You are talking about a X right? I have had horrible luck with RSD on DX and D2's....lastly I know if you use that Superoneclick that is in the andyapppack it has an "unroot" option....give it a shot.
