I have the Aladdn chip, right? I soldered it in, and everything works fine. It boots up with the proper flashes and stuff. and then I got my xbox to show the blue logo, which its supposed to do when the chip is booted right, but its STILL not playing backups. I tried to flash it with Evox and it wont read my CDRW. Then I took a risk and tried to flash it with Xecutor, and it still couldnt read the CDRW. WHATS GOING ON?!?!? READ MY BACKUPS!!
xbox dvd drives are pretty picky. Search for which media types to use with which drives (here and www.xbox-scene.com)
