When I fell victim to the 11th prestige hack luckily I was maxed out in level and I had all of my challenges unlocked but I've wanted to create a new profile lately so I could play through and earn everything back again but neither deleting game data, save data or even playing under a newly-created PS3 sub account has taken away the effects of the 11th prestige hack, even upon starting at level one again. I can't unlock attachments for guns or challenges no matter how far I surpassed the requirements. Is there anyway to undo this so that I can unlock the challenges again? Thanks for any help.
