It is obvious that we can manually install firmware versions from WebGUI, but what about CLI ?
You can display the 3 firmware version stored using show diag or as shown here: SMB Backup firmware version from CLI
Online update is possible if you run the following commands online in expert mode (sk141512):
# /opt/fw1/bin/fw check_available_firmware
# /opt/fw1/bin/fw download_firmware
# /pfrm2.0/bin/cloud_upgrade.sh
An upgrade from CLI is also possible offline (sk143274): Copy the image to the /storage directory (using WinSCP) and run (from Expert mode):
# upgrade_revert_image.sh /storage/%FILENAME% upgrade safe
And if nothing is possible anymore, even USB fails, we have - voilà - Gaia Embedded Boot Menu ! Reboot with console connected, wait until Hit 'Ctrl + C' for boot menu appears, and you see:
Welcome to Gaia Embedded Boot Menu :
1. Start in normal Mode
2. Start in debug Mode
3. Start in maintenance Mode
4. Restore to Factory Defaults (local)
5. Install/Update Image from Network
...
5. will load a firmware fw1*.img or u-boot.bin boot-loader file from a BOOTP or tftp server.
