The information in this page is updated in accordance with firmware version TRB1_R_00.07.07.3.


The 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 Firmware page for TRB143 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

TRB143 Firmware

New firmwares are periodically uploaded to this Wiki. To download firmware images for TRB143 devices, click here.

The name of the image file can provide some basic information about the firmware. Names for TRB143 firmware image files are structured as so:

example: TRB1_R_00.00.00.bin


  • <SERIES> - the series of the device. For TRB143 devices, the SERIES string should always be TRB1
  • <TYPE> - indicates the type of the firmware image. Possible values are:
    • R - release. These versions usually undergo extensive testing and are fitted for mass distribution. This is also the only type of firmware that gets uploaded to the downloads page
    • T_R - test release. A test firmware is usually compiled for internal testing purposes
    • T_DEV - test development.
    • T_F - test feature. A test feature firmware usually contains some new feature that is not present in the release version. However, unlike the release version, the feature version will not include other fixes, has not been thoroughly tested and approved for release
    • T_H - test hotfix. Hotfixes are firmwares that contain a fix (usually one) for some issue present in the release version. They are compiled when a quick fix is required and usually nothing else in the release is changed
  • <VERSION> - firmware version. The version part consists of 3 or 4 segments:
    • first segment indicates whether the firmware is standard or modified in some special way. If the first segment is 00, it means the file is a standard Teltonika firmware image. If the first segment is anything else (e.g., 01), it means this is a special version of the firmware, usually customized for specific customer
    • other segments indicate the firmware version number

Update Firmware

The Update Firmware 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:

Firmware verification

When you upload a firmware image, the device will have to verify the validity of that image. If the verification was successful, you will be redirected to window with a message such as this:

This means that the uploaded firmware image is compatible with your device. The indication also displays the file's Checksum. 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.

If everything is in order, you can click the Proceed button to begin the update 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:
