Summary
The Flash Firmware page can be used to check the current firmware version of the device and to upgrade the device's firmware - either from a local file or from server.
This chapter is an overview of the Flash Firmware page for {{{name}}} devices.
Flash New Firmware Image
The Flash New Firmware Image section is used to upgrade the device's firmware. Firmware can be upgraded either from server or from an image uploaded from your computer.
The figure below is an example of the Flash New Firmware Image section and the table below provides information on the fields contained in that section:
[[File:{{{file_flash_firmware}}}]]
| field name | value | description |
|---|---|---|
| Keep settings | yes | no; default: yes | Ensures that all of the current device settings will be kept after the firmware upgrade |
| Upgrade from | File | Server; Default: Server | Source of the firmware image. Can be either downloaded from Fota Free (Server) or uploaded from a computer (File) |
| Image (Browse) | - (interactive button) | Click to browse your computer for a firmware image file |
| Flash selected image (Upgrade) | - (interactive button) | Uploads the firmware image to the router and attempts to verify its validity |
Firmware verification
When you upload a firmware image, the device will have to verify the validity of that image. If the verification was a success, you will redirected to window with a message such as this:
[[File:{{{Trb14x_webui_system_flash_firmware_verification_succeeded_v1.png}}}]]
This means that the uploaded firmware image is compatible with your device. The indication also displays the file's MD5 and SHA256 checksums. A checksum is a sequence of hexadecimal symbols generated after running an algorithm called a cryptographic hash function on a file. Calculating a checksum and comparing it with the one provided by the file source can be used as a file authenticity check method. A list of {{{name}}} firmware checksums can be seen [[{{{name}}} Firmware checksum list|here]].
If everything is in order, you can click the Proceed button to initiate the upgrade or click Cancel to abort.
On the other hand, if the uploaded a firmware file that is incompatible with your device, you will see an indication such as this:
