Firmware Upgrade And Downgrade Using A Usb Mass Storage Device - Konftel 800 Installation & Administration

FIRMWARE UPGRADE AND DOWNGRADE
1.0.7
1.0.8
To avoid failure of the configuration file import or automatic provisioning, ensure
that you do not change the version number in a configuration file manually.
Configuration migration
The migration feature ensures seamless import of the configuration data in the
following cases:
• During the phone boot
• During the configuration file import using the web interface
• During automatic provisioning of the phone using Device Management
Configuration import can fail if the configuration file does not match the .xml
schema file. In this case, you see the following message on the phone web
interface: Failed to migrate configuration file.

Firmware upgrade and downgrade using a USB mass storage device

Konftel 800 uses the USB mass storage device to support firmware upgrade
and downgrade without the web interface. For that, the USB parameter must be
enabled in the configuration file. If you have the USB parameter disabled, USB is
inaccessible and unavailable for upgrade or downgrade.
When you connect the USB mass storage device to Konftel 800, the phone starts
auto-mounting and finds the firmware file stored on the USB mass storage device.
The auto-mounting and parsing process takes up to 30 seconds depending on
your flash drive.
Before performing upgrade or downgrade, the phone does not compare the
firmware version on the USB mass storage device and the currently used firmware
version.
If the firmware file is invalid, the phone shows the following message: Invalid
upgrade file.
The phone starts the upgrade or downgrade procedure immediately if it is in
Idle Mode. Otherwise, Konftel 800 ends an active operation and then starts the
upgrade process.
It is impossible to make calls or enter any menu on the phone during the
upgrade.
