I have a completely stock xbox360 elite and want to know if it is possible to convert XBLA games from trial to full versions, unfortunately I cant JTAG as my system has the latest update so unless a mirracle happens I'm stuck with a stock console, all I have managed to find on this so far is that you require a JTAGed console to be able to play the games after you unlock them, anyone point me in the direction of another method?
