Well I flashed back to 2.0.1 and ran DMUpdater to root the phone, but no matter how many times I try the Volume Up and Camera button together it never loads the menu you need for the next step. Phone starts fine though if not entering Recovery mode so I'm at a loss.
I had the same problem. It took me 6 attempts to get it right. It was a matter of timing and coordination I guess. I eventually succeeded, and I'm running a rooted Droid with 2.1 and tethering using Barnacle.
