Ok here's what you WILL need in order to do this

Xbox 360
Computer
Flash Drive
Modio.exe
USBXTAFGUI
NEED TO CLEAR SYSTEM CACHE

Now let's get to the processes. First, your gonna have to start a private match in a regular or xbox live profile. Next, end the game, and go to the Dashboard. You will now sign out of the profile and place it in a USB thumbstick {you may need to configure it first}. To do this go to settings>memory>hdd>gamerprofiles, then click on the one you were just signed in on. Move that to your USB thumbstick. Now we'll go to our computer

Now for the computer!

First, plug your USB into a usb port. After we must open up USBXTAFT.GUI. Got to content and you'll see something similar to this: E00046545HHF5, keep clicking on this till you can't click anymore. You'll see this like before E00046545HHF5 but with a different icon. Extract this to desktop or documents {I prefer desktop, it's easier to access and helps more in the process}. Now you will need to download this .gpd: Downloads/id=1300/cod-4-modded-gp...#dldetails. Now I suggest extracting this aswell.

Modio Part 1

First open up modio. Next, drag your profile into modio {E00046545HHF5}. Next go to contents tab on your profile window in modio. Find the .gpd you downloaded earlier. {415607E6.gpd} You'll see a duplicate of it already placed in your profile contents. Right click this and you'll see "replace" click replace. Now you should be in a new window. Where ever you put the downloaded .gpd go to there, and click the downloaded one. Now go back to the other tab where it says you profile and id's and click REHASH and RESIGN and in the bottom corner you'll see Rehash and Resigned. Once that says Xbox 360 dashboard you can exit out of your profile but not MODIO. THERE! your finished for now. DON'T CLOSE MODIO.

Modio Part 2

Ok, bring modio back up, and click on the BIG (M) in the top left corner. Go down to explore my device. Click open drive and do the same things as USBXTAFT.GUI, and find your last partion part of profile now drag your one saved onto your desktop into there. It should either say "replace" or "Overwrite" click yes. Now your finished and can go to your xbox.

Xbox

Now you can go to settings>memory>USBstoragedevice>gamerprofiles and move that to hdd. Now recover the account your doing. Next, unplug ethernet cable and get another controller to sign in to the recovered profile. As the first controller will be the modded profile you just did on the computer. Put in Call of Duty 4. Go to Multiplayer, and then System Link. Put Xbox live unlocks on. Now start the game and press.............
This contains : Super Jump, god mode, +2.417e007 per kill, cartoon vision
Activation : Start button, activated xp mod. Back activates godmode.

Now just have the second player kill the first player once after activated xp mod. End game and have 2nd player prestige, and start game again. Keep prestiging and starting till tenth prestige.


[size=24]There you go you officially did t10th prestige without a JTAG!!!

Warnings: You cannot dashboard until finished prestiging or the mods will disappear and you'll need to go to computer to repeat processes.

HAVE FUN
