Take a look at the following link:
http://www.xbox-scen...configmagic.phpYour K:5713 xbox is a 1.4 correct? I believe that configmagic works on it, but I am unsure.
Instead of following the readme to replace your EEPROM, you should be able to understand how to change your EEPROM from region 4 to region 1 by reading through it. I have never attempted such a thing myself, so I cannot give any advice, but here is what I believe should be correct:
Remember I have never performed this, so try this operation at your own risk.
Also note that there may be more steps involved as the original tutorial loads the EEPROM from a bin file and this is editing the one already on the xbox.
Good luck, let me know how everything goes if you try it.
