You can downgrade, there's a thread in the parent forum on downgrading. My understanding is that you shouldn't have to, however.

I assume you have Activesync 4.5 or later.

There's one more thing to try...get the official verizon upgrade, extract the nk.nbh from it, put that in the ruu folder, and try running the ruu directly. If that flashes, then try again from the kitchen, but run the ruu manually (you'll have to do it the automatic way first, then try it manually).
