this is the first time i have purchased a xbox and i dont have no information about xbox and modding. I purchased a Modded xbox 360 from ebay. the person who sold me this told me that the xbox is modded but he doesn't know which one. if its a jtag , RGH, Flashed or sum other. I m able to play pirated DVD's on it but when i try to play new games like batman arkham knight, it gives me an error of this disk is not supported, i also installed this game on my hard drive but then again its asking for disk. let me know if there is any special way to download games on your hard drive and play it. Also MFR is 2009-9-09 and dashboard version is - 2.0.15574.0 Let me know if your need any more info. Thanks in advanced.
