Personally I would have only dumped the first 2mb to verify if the console is exploitable or get xell ready for a complete flash.

To create a working freeboot image for your 512mb Jasper you need the 1st 66mb of your NAND which you should have dumped at least 3 times and compared all of them.

Write back your original 2mb dump, test the console with a full boot cycle then re-dump the 1st 66mb as I stated above. If all 3 dumps match you can proceed from there to create freeboot, write xell and then flash the created image.

I also take it that you got xell working now you made a note of your CPU key!!!
