Following the instructions found elsewhere for flashing SPrecovery for 2.1 using RSD Lite, I have installed the 64-bit USB drivers (I'm running Vista 64) and I have installed the latest RSD Lite, v4.6. I enabled USB debugging on my Droid earlier today. I booted the phone while pressing Up on the D-pad and I saw what I was supposed to see. RSD Lite saw my Droid. I selected the correct file and hit Start, but it failed immediately. No progress whatsoever, just an immediate fail. Any ideas where to start troubleshooting this? This is my first attempt at this, so I don't really know what else to look for. Thanks!
