Try pulling your battery, then plug your Droid to the wall or USB charge and see if it will boot up, if you can at least get into recovery, you should be ok, if you get into recovery, assuming that rsd didn't work, try doing a factory reset from recovery. It may wipe whatever messed your Droid up to start with.. if not, after you get it to boot into recovery and you wipe, unplug it, put your battery back in, and try to boot up or charge it.
Got it back to working this morning. Downloaded and put on my SD card both P3DF-SPR and P3DF-CW. I finally got into recovery which allowed me to install these two.
