      Settings → Console. This will allow executing shell commands right from UI.

    1. If you are running SMHUB-OS 0.2.1c - go to step 5. Otherwise, please update your SMHUB to SMHUB-OS v0.2.1c per this manual: https://smlight.tech/support/manuals/books/smhub/page/smhub-early-adopter-quick-start-guide#bkmrk-updating-smhub-firmw 

    2. Go to the terminal SSH (details here) and execute two commands:

    3. Go to "Apps" and verify that both apps are updated to:

    4. Once all updates are applied, open “Settings → Update and Backup” again - OS 0.2.2 will appear there as the next available update. Please click "Update" and reboot after successful flashing
    5. Please note, later, to update, one more (and only one) time you will need to to SSH command. All the further updates will be available via buttons in the UI.
