That means the Xbox is most likely a version 1.0-1.1. These didn't show the codes, so it's really hard to determine what went wrong, especially if someone else screwed it up. There are a few things that can point you in the right direction though. Has the Xbox been opened before? If so, check the IDE connections on the DVD-ROM and Hard drive, and even the motherboard. If it hasn't been opened, then most likely it is either hard drive failure or dash board failure. If the drive is dead it will give an error. If the dash can't boot it will give an error. IF you have a copy of the eeprom.bin file you have a chance of recovering the box (if you don't you can still get it with an EEPROM reader or just use a mod chip on it.) Unlock the drive rebuild it with XboxHDM and the original dash files (you can find them floating around on the net.) lock the drive with the eeprom, and put it back in the Xbox, boot up the Xbox, if that doesn't work. You may have a bad hard drive or motherboard. Do you know what color of LEDs flash when the error is on the screen?
