Now I have to call MS to fix it.
MS will not repair an Xbox if the warranty has been voided, which you have done by opening the console in the first place.

It's a spiderchip 1.1. It;s not gX.
It is the chip's fault.
Its actually the installers fault (Yours), but nobody likes to admit they screwed up so its easier to blame the chip. Happens with every sort of chip not just the Spider.
Xbox works....Attempted chip install.....Xbox no longer works.......The chip is to blame.
