Ah, I thought you meant before the downgrade, my bad.
I'll ask him but if I make a back up and use multiman, would I still need a fix for the files for BO2?
EDIT: Nevermind, I think I sort of get it. Gotta back up the files of BO2, put it in multiman but first I have to download an eboot fix, correct?
