6) Now you need to take your original profile, device, and console id numbers, and put them into the modded svg, replacing the 0's.
7) Now rehash and resign your svg, (do 2-3 times to make sure it got rehashed and resigned.
8 ) Now delete your original svg off of your flashdrive, and click inject, and inject the modded svg that you just put your id's into, onto the flashdrive
9) Now close the device explorer, and plug USB back into the xbox, make sure you click on the flash drive as the device to play on, and then resume campaign.
10) now you can play the campaign with the mods, or save and quit and go to spec ops or survival. (make sure you sign out of live at this point, to lessen chance of getting banned, i played online tho and havnt been banned, not yet anyways).
11) Save and quit the campaign, and you can now go play solo modded spec ops or survival.
12) If you want to play online with a friend, he must have the same mods that you just got or it wont work. (Playing online highly increases chance of getting banned).
