I'm in a bit of a tough spot here, I've been following tutorials on upgrading my HD and everything was going smooth but now I've run into an error 13. I believe this is related to the eeprom being incorrect, does anyone know how to get the proper eeprom? Help greatly appreciated!

Assuming you used xboxhdm to upgrade the HD (and thus have your eeprom backup on a CD or your PC!)

13 = dash error, bad key/missing files as in could not load dashboard.

or ur using an old exploit in a new xbox (doubtfull)

Anyhow, i figre you better but some files on your xbox hd.
