Getting CPU Key without screen input

[gamingking]

Hi,
Im just wondering is it possible to get the cpu key without screen input, i have jtagged an old xbox which has no video output to get the kv for my banned xbox, i know you can retrive the key with xell but i wouldn't be able to see it.

Is there any other way?

Thanks

Use XeLLous, the new XeLL.  It will run a small webserver that you can connect to from your pc and read your CPU key, download your NAND, and more.
