The firmware is on the SD card, so copying the relevant cards from a newer card can work.Is there any way to update the firmware on an OS from 2015? Hypothetically, if I could find a pi of that era and boot it, could I upgrade the OS somehow?
Follow the "Updating only the firmware" instructions on this document
I've got a PI 4B running Wheezy using this method.
