My Xbox is softmodded. Now it won't read any discs. Not even the originals. When I turn it on and it boots into XBMC, it says that the drive door is open, even when it's not. I don't have the game that was used to mod it(and even if I did, it probably wouldn't matter, since it won't read the discs). It was modded with MechAssault. Is there another way to remove the softmod? Or, does anyone have any idea what's wrong?
