Dear sir,
I bought a new Mikrotik RB450G these days. The original software version is 6.19. I want to use the last version of 5.x.
After downgrade to 5.26 and reboot, I found the software ID was changed and the license level was reset to 0. ???
If I upgrade the same RB450G back to 6.19, the license level 5 is back. I tried many times and got the same result.
Is the problem is a hardware issue? Can anyone help? I really need ROS 5.26.
