This can be done by booting via a pointer to the active system. The VERY LAST THING the updating s/w does is to change this pointer to point to the new systems.

That only works if you have space for both new and old to exist simultaneously. It is regrettably common to cut corners on space for firmware.

Well the other option is to keep a small bios type section which is not changed by changing FW. So if no FW is found the bios means the lens is still alive for the purpose of installing FW.

This complete suicide then rebirth method is quite stupid. One strike and you are out.
