Well, it's not like it hurts anything else really isn't it?

My hopes were that somebody may actually help me looking into it which
this would ease. However I understand that you NVIDIA people long since
stopped even having any of them older Tegra 2 and 3 hardware any
longer. At least Harmony and Ventana currently looks rather broken in
many aspects which I left for another days exercise.

Given the DFU NAND syntax being rather delicate at least Google
returning rather some wrong stuff with respect to now starting with
zero or one I thought that would at least make it clear. It's not that
a user could not overwrite it any time if he wishes to do so isn't it?
