As far as I know, no Routerboard device can be downgraded below the "factory-firmware" version. The factory firmware version can be determined by connecting to the device using WinBox, WebFig, or a terminal. This is an example from a terminal window for my RB4011 router that serves as my main house router (not an RF device):
You can see that the factory firmware version is 6.47.9 in the router.
You CAN downgrade to any version at or greater than the factory firmware version, so I could downgrade to 6.48.1 for example (not that I plan to).
