Xbox 360 hacking has been around for ages and has led to many different hacks being released...
I am posting links to each of the sites that host an Xbox 360 hacking Tool. No I will not be posting actual download links or Vscans due to the fact that each hack has it's own website forum and other stuff that isn't mine nor ever be mine..

 
Ok Lets Start with Modio.. Modio is in general a gamesave downloader it hosts millions of saves for each game and after transfering your profile to an USB stick put it into your computer pull up Modio Login and Download a gamesave and Save to your account....
Modio - https://www.game-tuts.com/modio/


 
Now Horizon... Horizon is a Rehash and Resign tool that includes a couple simple to use Single Player stat editing tools inside of it... I do not personally use horizon unless necessary due to alot of it feeling unsafe unless you go premium...
Horizon - https://www.horizonmb.com/


 
Another of my Favorite sites to use along with Horizon and Modio is the Tech Game... It is a site that contains many downloadable files that host Jtag/Saves/Isos/Tools/Etc...
TheTechGame's Website -


If I am not supposed to post links to a different website and the above things get removed just Google HorizonMB Modio and TheTechGame to find them...
