Ok well first thing you need to do is make sure you know what version of the jasper you have, its ever the 16mb one or the 256/512mb jasper (the one with build in memory units). Then get the correct verseion of Xell for your 360.
For 16MB Jaspers you need jasper_6723_hack.rar
For the 256/512mb jaspers you need jasper_6723_hack_256MB_512MB.rar
Then get Xellous (XeLLous_v1.0.zip)
Next you need your raw keyvault from the original nand dump (im guessing you have called it nand1.bin, this command will give you a file called rawkv.bin which you need to get anything new to boot.
nandpro nand1.bin: -r16 rawkv.bin 1 1
Now you need to inject your raw kv into the Xell image.
nandpro jasper_6723_hack.bin: -w16 rawkv.bin 1 1
Next you want to inject Xellous into the Xell imange
nandpro jasper_6723_hack.bin: +W16 xell-1f.bin 40
Now you have a file called jasper_6723_hack.bin that is your consoles keyvault and Xellous in it, so you then flash that back to your console using:
nandpro lpt: -w16 jasper_6723_hack.bin 0
After this is done power down for 30 seconds and then boot up using the dvd eject button you should get your keys that you were after. You will probably then want to flash it to XBR the steps are in that guide I sent you before (IMG:

You will also need the JTAG wiring in place for this to boot.
