BE SURE THAT YOU HAVE Hadzz GT Editor DOWNLOADED BEFORE YOU READ THIS.
HOW TO DOWNLOAD: search <Hadzz GT Editor> on TTG, it should be the first, or only thing that comes up.

1. Go to SYSTEM SETTINGS on you xbox360 dashbord and move your profile to a flash drive or whatever you call it.

2. Once you have your profile on your flash drive, go to your computer, and open up Hadzz GT Editor.

3. Click OPEN FROM USB (or whatever it says, depending on what version your using) and after you do that you will see a file (folder) that is called "E0000000000" and a bunch of random letters, and numbers.

4. Now you have to go through and keep clicking all the file folders until you have gone through all of them and have came to one single file.

5. Click this file, and choose "OK" or "OPEN" whichever one it says.

6. Now your profile will be opened in Hadzz, all you have to do now is put in what you want your name to show up as(colors and some buttons may take up more than one character)
Example: if I wanted to make my nome show up in green letters as "JTAG MODZ" then I would choose the color green, then type "JTAG MODZ" so on the gamertag preveiw it should show "^2JTAG MODZ"

7. After you have entered what you want, choose "SAVE" and save it to your USB.

8. Once you have done that you can keep your profile, and the modded profile names on your flash drive, and just start up COD4, or MW2.

9. While at the main menu, sign into the modded profile that you made, now choose multiplayer, and xbox live.

10. When you choose xbox live on while signed into your modded profile, it will pop up this message "THE CURRENT PROFILE IS NOT ALLOWED TO PLAY ON XBOX LIVE"

11. After this message pops up, just hit "OK" and sign into your original profile, and it should show the name that you typed in while you were using Hadzz. ENJOY!
