Fitted a Executer 2.3 lite flashed it and booted games fine played spiderman2 on it for 30 mins, my mate who i did it for came and picked it up got it home and all he got was Red flashing light constantly no display, iv'e taken the chip off and the D0 wire but still the same. I think the bios on the system board is fried, is there anyway to reflash the original bios chip?
Ok your xbox is fraging but because it worked at first it cant be the BIOS. Its the solder points, if you did the pin install take the motherboard out, get a pair of pliers and try and push the pins, if any go thro then put them back and re solder. It also help if you get a fiber glass pen and scratch the D0 point
