You do not need to downgrade your firmware!
Maybe you want to downgrade your RouterOS, that is not the same as your firmware.
The version would be something like 6.x not 3.x
Why do you want to downgrade? To get the situation before the bridge/switch change?
Then you would have to download the 6.40.8 RouterOS version (bugfix).
