	* Install Cable as above (F256K2 Powered Off)
	* Plug Cable in any PC that holds the new programming file.
	* Keep 1 finger on the button
	* Power the F256K2
	* A new folder will appear on the PC's Desktop
	* Drop the new file in the newly appeared folder.
	* Power off F256K2
	* Remove cable
	* Reinstall the system as your heart's desire
	* Power On the unit
	* RP2040 is updated and running (because you need it to boot the unit)
	* Bob's your uncle!

			'''Important Note''': for the F256K2, each core has its own dedicated area of 512K of flash memory. When switching to a new core, a separate dedicated area of 512K exists for that core and there's an expectation that the process of flashing the firmware has to be done for it.
