hey guy,
i just upgraded my RB433AH from its default os version (3.10) to os version 4.17. it asked me to upgrade my licence which i tried doing. the next message i got is dat d licence is invalid and that i should purchase a new licence or my router os will stop work.
please how do i reverse to the old os that was installed initially.
thanks in advance

if you can get in with winbox go to the files tab on the left and open the box. then you drag and drop the mikrotik version of the ROS you want. In this case 3.30. once the file is copied to the file box you go to system on left tab and click packages. you then click on downgrade. it will reboot and install the "new" ROS. It will take several minutes to install and boot up.

I hope this is what you are asking and helps you.

You may have to contact support. I've had a couple upgrades (out of 70+) that didn't go smoothly, contacted support and they got my board working again.
