First off I apologize if this is in the wrong part. I recently have had my 360 modded. I have a toshiba Samsung. The guy who modded it apparently modded xtreme 5.2b. Since it's been modded the more I play it the more, Disc problems I have. Such as Dirt Disc or Unrecognized discs. Also the burned games aren't the only games with this problem. My orginals now won't play. They crash if two people are playing it, and the dirt or damaged disc message comes up. I've even had this isn't an Xboxd 360 disc. I took it back and had him relook at it and he didn't notice any problems until I pointed it out to him. I'm assuming that he's never encountered this problem. He suggested that maybe 5.2b isn't working well because I have a ms28, and he has the same mod on his xbox 360 but he has a ms25. He has suggested that Xtreme 5.2C would work. My question is, is it normal for the orginals to have problems. And do you thionk that this is purely a mod related problem did he make an error modding? Any help would be apprecaited.
