When flashing a rom, have you ever gotten the never ending bootloop? I was trying out Rubix tonight and something went horribly wrong when my Precious (Droid X) started to boot. I had nothing but the stupid "cube thing" loading over and over. My Precious is dead! Gotta flash SBF right? WRONG! If this happens to you, do a battery pull, hold the home key down, while you put replace the battery. You will boot into the real Factory recovery and although you can't retreive any backups, you can factory reset. This is a helluva lot better than flashing an SBF! My Precious didn't reset exactly, but it forced it to load. I was then able to reload my apps and go to ClockworkMod recovery and load my backups.
Go ahead and tell your friends. I hope this helps and saves you hours of time.
