Deleting Game Data won't do shit. It won't unlock because your save data has the conditions already met (so copy it to usb and delete from ps3, then restore later) or because the server is recording your stats and it's got the conditions met.
Or you haven't done it at all, so double check you are meeting the correct conditions.
I have deleted both save and game data and have met the criteria for both more than once and I have game screen shots of the trophy unlocking and it not appearing in the listings, I have both trophies on my second account it just my main account seams to have a big in it for these two there are many others on the ea forum that have the same issue just wondered if anyone could think of anything as ea support are less than helpful even with the necessary proof they still won't / can't do anything
