I believe that I have not seen a MW2 Gamertag Mod USB Step by step yet so here you guys go.
I do
not take credit at all for any program or Youtube video, I just compiled what I've seen together
It'll be easier to do it if all you do is put your profile (Your Gold Live Account you use) on the USB flash drive instead of having to find it through a bunch of stuff

There is the video he is using a slightly older version of all the programs but you should be good with the newer versions. in the video he will say after EzGT you need modio, but he is using 2.1 and i gave you the link for 2.2 so you do not need Modio, you can just save the gamertag right from EzGt and skip the modio step.

Instructions:
1. Plug in your USB Drive.
2. Open "USBXTAFGUI"
3. Push "File" -> "OpenDevice"
4. Double Click "0. {dir}Content" and browse to the file (profile) you want to mod. Push "Extract".
5. Browse to where you want to save the contents (Desktop). Keep the name as it is.
6. Find your new file on your desktop or whever you saved it.
7. Open up EzGt 2.2 - change it to whatever you want
8. (if you want more than one modded name) go to options and change the modded profile number accordingly so that when you inject it on the usb it will not overwrite
9. Save it onto desktop (it'll be a series of folders)
10. Go back to "USBXTAFGUI"
11. Click ".." to go back to the main menu and Double Click "0. {dir}Content"
12. Click on "Inject Folder" and select the folder from the desktop that you just saved
13. Exit out and plug into XBOX
Now for the
Xbox part
14. Boot up MW2 (doesn't matter if you are signed into your gold account) - Go to Multiplayer
15. (Sign out if you are signed in) Log in to your modded name (just click middle xbox button when avatar selection comes up)
16. Click "Xbox Live"
17. Message should pop up saying you don't have axcess - sign into your Gold Live account you normally play with
18. there you GO! (you will have to re-do you brightness and Hud markers everytime :/)
19. The first game you play everytime will disconnect you due to "invalid sign in status" and you will have to repeat steps 15-18 every "first game" you play
