I'm considering buying a broken Xbox and from the description (flashing red light and no audio/video), it looks like the EEPROM is corrupt. I found this
guide using Cromwell to fix the EEPROM, but since I don't already have a backup of the original EEPROM, I'll need to flash a donor EEPROM. How exactly does this affect the hard drive, which is obviously (at least initially) locked to the old EEPROM? Does updating the Xbox with the donor EEPROM also automatically lock the hard drive to the donor EEPROM? Or will the old hard drive basically be dead to me with no way to unlock it?
