Considering what was discussed before, it's probably not possible to
download the fw from the chip. If it indeed is such a big secret, the
chip most likely has the firmware locked away. So unless there is a
serious design flaw in the chip, you can't get the code.
However, the fw can probably be overwritten (well, first erased and then
rewritten). Without this ability the fw couldn't ever be updated. It's
very unlikely, though, that *you* will be getting the required
documentation or equipment for this, considering how big the secrecy is.
