WARNING: The developers or I are not responsible if you get banned from Xbox Live. Use on you're own CAUTION!
Just wanted to share this amazing program for the 360, its called ExProfileEditor. It allows you to mod your achievements, change how many years you have had Live, Change your avatar color, load GPDs, and much more. But be cautious and do not over use it or it might lead to a ban. I recommend to not modify you're Xbox live years or you're avatar color because that can easily be spotted and you have a higher risk of being ban. The achievements, however, are not as "risky", but it is still possible you could get caught, so use this on you're on caution. I've been modding the achievements for a couple of weeks now and nothing has happened to me so you should be okay just don't mod like 15 games a day (What I do is around 2 games per day if I mod any) & I would also recommend if you're going to mod you're achievements then use GPDs because it lowers the chance of you getting caught. The link to get this program is here: http://v3n3.org/?cat=4 just download the latest version and extract your Xbox profile from you're USB to Horizion and you're ready to go. If you need any help with this program then there is a tutorial on the website that guides you how to use it. Also if you are looking for GPDs I would recommended this website http://exgpd.luci5r.com/. It has over 200 GPDs ready to download and they are all in legit order and 100% complete (atleast as I know). Make sure to thank the Developers! Anyway, hope y'all enjoy this dope a** program!
