I have a sneaking suspicion that this only worked because you hadn't already done the 'fix' where you delete the Black Ops 2 Game Data, create a new account and then use that one WITHOUT deleting homebrew apps. I am fairly certain that if you've already done this fix, wiping your HDD won't do anything.
