i had 88780 gamerscore before i got caught! is there anyway i can re-mod it back to that amount?
Suggestion:
What's the point of trying to get your score back. You'll always be labeled a cheater, and anyone who sees your gamerscore will know that you're a cheater. You already can't earn those achievements again, and if you mod your score again, just means that there's more achievements that you can't earn again.
If you want your original score back, you earn the points. Unfortunately for you, you can't earn those achievements again. You'll have to earn new achievement points.
