I have a problem with my Cygnos Chip, I think i f***ed it up. I tried to update my freeboot image, after writing the NAND (sucessful) the Xbox got RROD. I think i powered the box on and was still connected via usb.
My problem now is that i am not able to flash any new nand, because the cygnos is always a unknown device in windows. Is there a solution for that problem? And what could be happened to the chip? Is the xbox nand damaged, or can i just buy a new cygnos, solder it in and it will work again?
