To the best of my knowledge, there are no firmware upgrades that require
hardware changes. The firmware is written to figure out which version
to load - an example is the old and the new DSP board - but that was
long ago.
The converse is NOT true - some hardware changes require firmware
upgrades to make them functional.

Quite so.
However, this sounds like a pretty old K3 that hasn't been blessed with
certain or any factory hardware mods which will have a bearing on
features available and detailed in the revised menu options.
At the very least the firmware release notes, which are presented in
historical detail with each firmware release, need to be read through.
Regards and good luck,

Joe,
I cannot recall any instance where the firmware upgrade broke the K3 -
same for the KX3/KX2.
There have been a few who suspected a problem with a firmware upgrade,
but it turned out to be some other problem.
I would recommend that you simply upgrade to the latest and be done
with it.
