I have a modded xbox, which I have set up as a XBMC - NTSC for dvd upscaling. I am happy enough to leave it as it has, however want to know if and how it can be reflashed. The header pin install I did 3 or 4 yrs ago (with shaky hand), and the chip was pre-flashed when I got it. I have tried to get an answer from cheapmod via e-mail, if it is worth reflashing the chip but no response. Do, I have to use a cheapmod bios reflash, or do I risk toasting my current mod chip by reflashing with any of the other flash options available?? How do I find out what bios my chip has installed, and is there anything to gain from reflashing if I find a suitable one?
