(adsbygoogle = window.adsbygoogle || []).push({}); So ive been thinking about modding my GS again and im wondering if this way still works.I was going to do it for a friend but when I went to recover his gt it said that any achivements unlocked during his last sign in will be removed.So will it still work?

Yes but after some weeks u get gamerscore derank, and a last chance if do it again then u get perma band, ive done this years ago

Do it, cause then when you get reset, you keep a whopping 0 GS for a few months. It's awesome!
