This may be a completely noob question but do you have to have a modded Xbox to use or install title updates on a Xbox without xbox live. Cause I installed like 5 different tu on minecraft and absolutely nothing changed.
Did you put the TU on a usb? Whatever program you use make sure the TU goes into the cache folder. Then transfer the TU to your hard drive. Might work but I had problems like this before but when I put them on my hard drive it worked Goodluck !!
