So this guy bought a rghed xbox off me. Lately the new update has came out, and he followed what his friend told him to do. He updated with the same nand as his friend lol. So the cpu key was wrong for his console. Anyways, he will send it back into me, I got all original nand info/cpu key/dvd key. So in his case now, when he powers on console the green light flashes, fans do not run, and a red light on the psu. My question is can I just write in the nand through the wires fine (nandx) without any problems? and will it still work. Thanks in advance.
