well if you need help try www.360mods.net … but if you dont own originals they cant help you.
i would offer some more advice but i aint sure if i can offer to much help since even though u said you got the original… i aint sure about the ‘downloaded’ stuff so i wont say more for now
p.s. you could have moded it yourself! … it’s not hard if you have a desktop pc.
cause with this… http://www.newegg.com/Product/Product.aspx?Item=N82E16815124022 … it will basically mod any modable xbox360 to date (besides hitachi 79 drives which require soldering)
