Have any of you managed to play any DLCs off JTAG/RGH? I managed to get Leviathan and Citadel off Ehsan bhai/Techmology today, but the email doesn't show up in the private message terminal that starts the mission. I already finished the game and it reset me to the point just before Priority Cerberus HQ and after everything else, so the mission requirements are met.
To install the DLC, I moved USB0:Xbox 360LC:Citadel:45410.... to HDD1:Content:000000... as I think I'm supposed to, but nothing happened. Please help!
