Hi guy i have a small prob with an eeprom. A v1.4 board seems to have trashed the eeprom and the hdd was still locked.

I have remove the eeprom and read it in a programmer. the resulting bin is 256bytes and looks ok to the eye. same ammount of bytes writen as a good eeprom when compaired side by side.

Config magic will not load the bin and complains. Eeprom encrypted Region invalid.

Eepmod v.03 reads eeprom ok
System video region 00014000
Online key is ok
Serial no is ok
Mac address is ok.

Live info2 complains The eeprom could not be decrypted. This is not a valid v1.0 or v1.1 eeprom image

I need to get the hddkey from the bin but nothing i have reads the info from it.

Eepmod seems to get some of the required info but does not support the hdd key.
Maybe Superfro / Dextrose could help me out.. maybe add the hdd key to the next release of eepmmod..

Anyone have any more ideas / software

TIA

http://arisme.free.fr/Xbox/Reflash/ would not work on my box or did not lke my lpc2 cheapmod !!

Tools needed:-
Elvis programmer ver 3.5 serial (not usb version) from http://www.adteknik.se/english/index.
MP ver1.40b by TJ 1965 available from http://www.adteknik.se/english/index.
8 short wires to use to extend the eeprom smt legs

Step 1)
i remove the eeprom chip from the board and wired it up with short wires.

step 2)
start MP ver 1.40b and select the i2c page and wire the chip as in the picture on the i2c page.

step 3)
read the contents and save to a bin.

step 4)
load your backup or another working eeprom bin file and write that to the eeprom.

step 5)
Remove the eeprom and the short wires and solder the eeprom chip back to the xbox board.

step 6)
rebulid the xbox and if all is well with the soldering and reprogramming then it should work fine..

The symptoms of my eeprom problem was when you powerd the box up it once flashed green then changed to just red flash. No screen display or sound.

I might turn this into a tutorial at some point... it anyone wants help with pictures that is.
