how do i change the name of my xbox?

[dataeraser]

I've changed the name of my xbox before by sending one file from my xbox to pc and hex editing the file so the name of it would be able to change. That was a few months ago and i forgot which file it was. could anyone help me out? thanks

the readme of the program should tell u
if not just use doa3 and put a highscore in
cuz that changes the name too

I believe its a file in the udata folder, might be tdata though. It's just loose in it and is the only file i believe, so it should not be too hard to find it.
