We have hAP ac^2 with Factory Software 6.42.3
How to downgrade the ROS below the factory version (to 6.41.4)?
After /system package downgrade
we get error
error: omitting package system-6.41.4: min RouterOS version is 6.42.3

This is correct behavior.

But why??
We have another hAP ac^2 router and it works fine with version 6.41.4:

It has been programmed at factory with 6.40.5 so 6.41 is newer.

May I ask why downgrade to such a vulnerable version? Wouldn’t be better to upgrade the other equipment if having the same version on all hardware is important? I wouldn’t have any of my mk’s on anything below the latest bugfix these days.

Due to a this bug in 6.42.x:
