Nope, almost certainly not firmware damage.
Can get confused that it is firmware damage because some ace has solution for
"Unable to load Overlay", but this possible solution, (which does not work very often),
is just a bypass of some Seagate function in program to give access to drive.
But this solution does not fix any firmware permanently, just temporary bypass.
So there is no firmware damage
Solution in almost all cases requires some physical work.
