I just finished refurbishing a broken v1.0 xbox, and everything works fine, good as new. I also just finished installing an X3 chip, and now it powers on and off 3 times, and on the third time stays on, and flashes red and green, or frags. The chip has 2 blue leds, and the "X" on teh bank selector switch is red. The xbox will work fine if I remove the X3 from the pin header, but frags everytime it is on it. I checked my soldering adn everything appears fine, and I skimmed over the traces with a razorblade just to be sure it was. I can't figure out wtf is wrong with this thing. I think it may be the chip. I got it off of X-S, and the guy said it was new. It all came in the original packaging, and appeard to be in perfect condition. I also tried to boot from the backup, and received the same results. If anyone has any idea's please let me know. Thanks.
