Hi guys. I have a mikrotik CRS fibre switch mipsbe v6.49.8. When it reboots, it delletes each and every configuration including ip, interface, etc. The ip sets back to 0.0.0.0. I have tried to use netinstall 6.49.11 as I can't find netinstall 6.49.8 . But it is not discoverable in netinstall. When it is configured, it works well until itbis rebooted .
Do not talk about upgrading becau when you upgrade, it downloads the firmware and on reboot, it goes back to 6.49.8.
Kindly assist

You should netinstall...

I have already tried as mentioned above. Unless you can guide on a better way

You never specified how you already tried ?
It can take multiple tries.

You can also use Linux ( I do, 100% success rate).
Or put a dumb switch in between.

Can you rule out Hardware issues like a permanently pressed Reset button, preventing the Bootloader to install Upgrade packages and revert to a clean config?
