You must login or register to view this content.
Create a file called "NGU_ELITE.txt" and inside, place your elite key in the format XXXX-XXXX-XXXX-XXXX. (Make sure you do not have any spaces.)
Place your elite key and the Defcon9.sprx file in /dev_hdd0/tmp/
Place the EBOOT.BIN file in your MW3 USDIR Directory.

Copy your tmp folder with everything inside of it onto your Desktop using Filezilla etc.
Delete the tmp folder with all its contents off of your Playstation 3

Copy over the contents from the tmp folder you put onto your desktop into the new Playstation 3 folder
