Is that where you got it from?

So it has a 6-pin POGO connector so the current firmware may be readable (if not protected). And/or HP firmware dated 2015-01-08 could be loaded. Or HP-15C CE firmware

PS: Have you checked for hidden Platinum/Prestige functionality? Is there a delay showing the firmware info?
