I'm a bit confused as to what all I need to do in order to update my ROM from 2.1 Bugless Beast 0.8 to 2.2 BB 0.4. I've obviously already rooted my original Droid and everything and I just need to know what to do with the stuff contained in the 2.2 download. I'm being extra cautious with this since I would hate to brick the phone. I've looked at a few steps in this guide that I used like five months ago for 2.1. I'm just making sure that it's fine for me not to have four files since there was nothing labeled data.tar in the .zip that I downloaded. Do I just follow steps 27 through 44 in that guide replacing everything with the newer ROM?
