Ok, looked into it a little further. It seems possible to use the udumper code to
dump not firmware but memory, but I'm not sure if that's what you want.
Reason: this memory dump would just reflect the memory right after
highjacking Canons firm update routine, and would always produce
the same results for a given cam. besides, looking at the udumper code,
in order to even start on DryOS it needs to wipe a large chunk of memory
which makes it even less useful ...
All in all, I don't think I can be of any use to you guys with this ...
if you think otherwise, let me know
