I am trying this and I keep getting a failure when I try and flash.
It says my Droid X Failed flashing process: Failed flashing process. Phone[0000]: Phone is not compatable with multi-interface super file. [0x703B] Phone connected. HELP!!!
Sorry to leave you hangin there, I've been trying to think of what I did to fix this error. A few things that came to mind:
-Run RSD Lite as Admin
-Make sure the phone is in bootloader mode
-When in bootloader mode and connected to computer, make sure phone says "Okay to Program"
I'll try to think of some more solutions, I know how frustrating it is to not have a working phone.
