I am trying to understand / find out some info re modem firmware upgrade process.
Can this be done across the LTE connection, i.e. I connect to device remotely via the LTE connection to upgrade?
How does the upgrade process work, is it similar to ROS upgrade where it downloads to another section / partition and only applies the new version once you restart router / modem?
How successful are the firmware upgrades, i.e. do they brick a lot of devices?
I have 2 customers with SXT LTE devices, one is on v8 and other on v10, latest being v13. Is v13 safe to apply? Is it worth it to upgrade?
The terminal connection is required for all steps to finish. However you can work around this limitation with scripts and schedulers. Try this script, just copy and paste it to a terminal: unattended-lte-firmware-upgrade
The modem is switched to a specific mode where it downloads the firmware itself. RouterOS does not have network connection at that time!
I’ve installed all updates on all my devices without issues.
