I've a flashed xbox360 with d'hbrd updtd to 13599. I'm able 2 play XGD3 titles like Gears of War 3 n Batman:Arkham City but not AC: Brotherhood. The error i get is " The disc is not supported " Although, I got it pre-burned, I tried to search for patch instructions with abgx. I downloaded agbx 1.0.6 and patched it with "Autofix" set to "Level 3" Then I burned it with imgbrn at speed of 2.4x. Sadly, I got the same outcome. Don't know how to patch an XG2 Game for LT 2.0 fw PLEASE HELP P.S.: As my drive is able to play some XGD3 titles, I assume its LT+ 2 (maybe).
