We had a firmware version older than TRB142X_R_00.01.06.1. We uploaded  directly the mass production firmware (TRB1_R_00.07.01.2) to our device without realizing that we should install first the LEGACY code. And now our device do not work properly. We tried to install again first the LEGACY code but we get an error. We also tried to reset the device to the manufacture settings but it does not change the firmware version already installed. We do not know how to follow. 

Could you please help us to reset the device? 

Thank you very much.

Thank you for your answer.

Indeed, we already tried the solution of this link but it does not change the firmware of the device. 

Our problem is that we did not do the intermedium step for versions older than  TRB142X_R_00.01.06.1 before to install the updated firmware (TRB1_R_00.07.01.2) and now our device do not work and we cannot install older versions of the firewall to start again all the process. We need to reset not the device but the firmware.

How could we do this step?

Thank you.

Hello,

Please try to perform the following procedure with this TRB device:

1. Turn off/unplug TRB142.

2. Press and hold reset button, at the same time plug the power cable and keep holding reset button for about 5 seconds (mobile signal LED's should start blinking).

3. Download "ADB software" and "rootfs.ubi" file from here: https://kaunas.teltonika.lt:444/f/a9ffe2e9d98446f2aaf3/?dl=1

4. Install ADB software.

5. Place rootfs.ubi file in any easily accessible directory (e.g. in "C:\Test").

6. Open CMD ("Command Prompt" window) with administrator rights.

7. Use cd command to navigate to the place where you saved the rootfs.ubi file (Example: cd C:\Test).

8. Then use this command: fastboot flash rootfs_a rootfs.ubi.

9. When it completes, use this command: fastboot flash rootfs_b build rootfs.ubi.

10. When both commands are executed and finished running, unplug power from TRB and plug it again. It should boot up as normal.

11. Install intermediate firmware version, which can be downloaded from here:

https://wiki.teltonika-networks.com/view/TRB140_Legacy_FW_Upgrade_Instructions.

12. Install desired firmware version to TRB through WebUI. Latest firmware can be downloaded from here: https://wiki.teltonika-networks.com/view/TRB140_Firmware_Downloads.

Best regards,
