i heard u also need to completely erase the cd-rw, even if its new. make sure ur running the chip on, not familiar with matrix mod chips, and i dont hav cd probs cuz i hav a samsung, but make sure ur not on a setting that isnt supposed to 'boot the original ms dash' or 'be able to run live' thats not what u want, u want to make sure the damn mod chip is on. not sure if theres anything else...
