This is what I used to get out of trouble and it couldn't have been easier to use.
http://arisme.free.fr/Xbox/Reflash/I was able to flash my EEPROM using my backuped EEPROM.bin and cromwell bios. I left this on one of the available banks on my X-B.I.T for future mishaps (just in case). Wish I found this link before I tried Config Magic FINAL as well as Enigmah video selector w/o any luck.
