Heres a tutorial i worte for another NGU member a while ago, just substitute mw2 with cod4 adn youll be good, but you will need the cod4 blus/bles codes located on the side of the games case. (this tutorial may seem lconfusing to you, this is only because you may not know some of the terms, i have tried my best to make it "noob friendly") :p

Things Needed_
1)A ps3 on ofw 4.00
2)A ps3 on fw/cfw 3.55 or lower (which you will get after a new downgrade comes out)
3)An Ethernet cable (it looks like a big blue phone line cable)
4)A usb port (storage drive) (thumb drive) (junk drive) (flash Drive)etc. Whatever you call it
5)A file manager of your choice (e.g) The Well Known "Comgenies" or Multiman or , Black Box Hooked up to a Ftp Server Such as File Zilla.
6)A modified Patch for mw2 v1.13 unless you want to bypass and stay on 1.11 But im not gonna go into that as of now.
7)A copy of cod4
8.Some Common Sense
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
_First Steps_
If your ps3 is on ofw 3.55 please upgrade it to 3.55cfw such as geohotz.
1) On your usb make a folder called PS3 and in that folder make another folder called UPDAT
2)Place the cfw updat.pup into that folder
3)Safley remove hardware from your computer
4)place usb into you ps3
5)goto update via storage media device
6) UPDATE!
Now that you are on Geohotz
1)Plug you usb back into your computer and on the root of your ps3 you want to put the filemanager of your choice .pkg file
this will be like Comgenies file manager signedfor 3.55cfw and will be in a .pkg form with a title such as up000pu00300-u00pu00
after you place this on the *ROOT* of your flash drive place the flash drvie into you ps3 and on the main xmb menu on your ps3 you should see a new folder under the games option called install package files.
2)CLICK IT
3)install the file called UP00023- etc..
4)now that you have the file manager installed it should show up on the list of games or programs you have downloaded from the ps store or anywhere else.
5) Now makesure that you take the patch you want to use for mw2 and place it into a folder on your usb called "ModdedMw2"
6)make sure you have mw2 installed on your ps3 with cfw/jb.
7)While having you patch on your usb the the folder go onto your filemanager on your ps3 (Makesure your usb is in your ps3)
8.Now heres the tricky part where if you F*** up, you are screwed cause you could brick your console (no worries tho)
9)While on the left side of your file manager you need to navigate to the mw2 patch currently installed on your system.
Hdd0----> game ----> blus30077----> USDIR.------> Patch_mp.ff (blus/bles code will depend on your region but should most likly be that) now once at your patch_mp.ff you want to navigate onto the right side of the file manager by pressing "of course" RIGHT on the dpad.
10) Now that your on the right side go down to any usb000# an than click it.
11) Find you patch in the folder that you labled earlier and once you are over your patch press O, than the start button to copy it over the previous mw2 patch.
12) Quit the game (file manager) and now take out mw2 from your modded ps3 and put it into your 4.00 ps3
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
_Data Transfer_
1)back up anything you want to save on your 4.00 ps3using the backup utility found uncder system settings.
2)after you back up all your stuff turn off you ps3 on 3.55cfw/jb and your ps3 on 4.00 and connect the two with an ether net cable.
3)turn on your 3.55cfw/jb ps3 and set your tv to display its image.
4) on that ps3 goto system settings -- data transfer utility -- and if it askes you abou the tropies and psna ccount say no to both.
5) now it should say set data transfer on the ps3 recieving the data so do as it says and set ur tv to display that ps3
6)Do what you did in step 4 but select recieving data instead of sending.
7) If all goes well you should have to reformat your 4.00 ps3 and than transfer the hacked data onto it and than have a modded mw2 patch be playable
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
_Fun_
1)Play mw2 with your hacked patch
2)Show off to your friends
3)Dont get too Cocky
4)Learn More about modding so you dont need tuts on simple things anymore
5) Enjoy!
