So you tried, "How to fix christmas lights/bad flashes"? Make sure you unplug all the wires.

so basicly i dont think i can still use xell to reprogramm my jtag. is it still possible to reprogram it by manually using an lpt cable an rewriting it.

Make sure your 360 is plugged into a power outlet first then plug in the usb.

If that doesn't work you are basically screwed.

You most likely need to short the nand. After doing so then it should be able to read the xbox and you can flash xell and fix it .

Voila: Shorting the Nand

yea i did that nand shorting thing abit ago using the first "safe" method and now my xboxs nand is fried i think. everytime pluging in the pwr cable it gets a red light making it not pwr the xbox. im wondering if i can swap a nand chip from a different xbox or is there a solution to this.
