Backup success!!

After trying different ways to do the back up, I decided to build the Jtag wigller cable and do the backup that way. I used the program called urjtag. It takes about 6 hours to do the full backup, but finally is done. I made 2 backups, one in big endinan and the other little endian.

I hope this backup works because I was taking a peek to the images with a HEX viewer, it does not look like there is very much on it. Is there a way to test or verify? I did 2 runs and then a binary diff. The 2 files were exactly the same.
