Unlocking achievements wont work

[Spankywild]

So im trying to unlock Gold digger an achievement from Ufc that cant be unlocked anymore. I have been using le fluffie to unlock it but every time i log into my Xbox it just shows my Gamerscore as 0 i even try to play a game or go to avatar creator and try to make a new one but nothing works? i wonder if any of you "modders" did anything like this before and knew how to fix it.

Personally, i never got lefluffie to work. exProfileEditor works perfectly, though.

But I mean, if you honestly think unlocking an achievement that can no longer be unlocked won't get you caught (hint: it will), then go for it.
