Gametuts have since stated on a post on twitter that they have been discontinued.
Modio was an amazing mod tool for Xbox 360. Users simply had to search for the desired gamesave they wanted and boom - modio does all the hard and rather boring work of putting it on your usb and setting it up to be accepted by your Xbox 360 console. I even used it to mod gta 5 campain and gave myself unlimited money, health and stamina.
However we can no longer use this god like usb modding tool anymore because Gametuts no longer host the files required meaning you cannot download or upload anything. Now I have to use Horizon. It is useful but hard boring work. I cri evri tiem.
Never the less, there are plenty more modding tools out there and we will just have to move on and accept defeat. Hard as that is.
