Xbox EEPROM Fix
A Fast & Legal way to reflash your EEPROM with Cromwell
Just in case you manage to do something stupid and fry your EEPROM (and your box won't boot
anymore), you can fix this with these easy steps since Cromwell provides everything to flash your
EEPROM
Requirements
• EEPROM backup, before the disaster (if you don't have one, ask a friend who doesn't
play on Live
• Flashable mod
Quick install
Download the patched Cromwell image here:
http//arisme.free.fr/Xbox/Reflash/Cromwell-patched.zip
Download the EEPROM patcher here: http/arisme.free.fr/Xbox/Reflash/addeeprom.zip
Unzip the image and the patcher, put both in the same directory with your EEPROM image, and
patch the Cromwell image with your EEPROM:
Program your mod with cromwell-patched.bin
Boot your box and wait a few seconds - you should see a message "EEPROM flash - status:
SUCCESSFUL"
Your EEPROM is now restored; you can turn off your box and reflash with your favorite bios ...
or install Linux. As a side note, if you want to install Linux I'd suggest you to download an
official Cromwell image as I'm not sure of the quality of this build.

Note that you'll need a fairly recent gcc to build Cromwell - 3.2.3 seems to generate something
consistent if not perfect:
