The NOR is not flashable on the Freerunner (sans debug board, or
special versions).  It's your failsafe should you break your NAND
bootloader in some spectacular fashion.

This is why you go into NOR for flashing, since it is invariable over
all the changes you can do to the system.

I still recommend using NeoTool for at least backing up, as it uses an
ssh connection and mkfs-jffs2 to create an image of the rootfs, rather
then fiddling with dfu-util.

Hope that helps in some fashion.
