I was recently trying to RGH another xbox. Installed the wiring properly and was ready to write the xell image to the console to get the cpu key. But, when I tried to create an ecc image it gave me an error writing the header. I looked it up and people said that it is due to not having the original nand. I could not remember if I had tried to RGH it before. I need to rebuild the nand but I need a cpu key to do it. Is it possible to write a trinity ecc to the consoles first 50 blocks so that I can get the cpu key to rebuild? The console red rings, so I presume it has a corrupt nand.
