update the xell with xellous
open the xellous rar image and extract xell-1f.bin
nandpro usb: +W16 xell-1f.bin 40
once this is done remove the power cord and wait 30 seconds or so,
plug in the composite av lead and the network cable,
If it has worked correctly then after the blue screen with writing you should see at the bottom the dvd key and the cpu key displayed for you, and then a line httpd listen: make a note of the ip number after that, (you can just write down the cpu number but this takes the human error out of the equation)
open up firefox on your pc and type in that ip address
you should be prompted with a white screen with some options.
click download for fuses this gives you a txt file with cpu key and dvd key.
once you have the info power down the console.
