FW upgrade problem - RouterBOARD 750G r2

Hi

I have problem with upgrade my RouterBOARD 750G r2

current-firmware: 3.23
upgrade-firmware: 3.23

I uploaded to root directory routeros-mipsbe-6.43.8.npk and reboot device, but after restart fw file is disabled

How can I upgrade my box? Thank you for advice

In similar cases it turned out most of times that either device was hacked (and only way out is netinstall it) or there was some mismatch between packages installed (and netinstall is the way out again).

Is there anything about failed upgrade in logs?

The preferred method of upgrading, though, is to run the semi-auto process on the device:

/system package update
check-for-updates
install

After reboot (which finishes the ROS upgrade process) you can upgrade also bootloader

/system routerboard
upgrade

Another reboot is needed after that.

With some routers you need to place the upgrade file .npk in the /flash folder, not the root. If placed in root, it will be deleted during restart
