Hello,
I have been working on a package for the TRB143 that adds some functionality we would like using firmware TRB1_R_GPL_00.07.23 SDK download. To ensure I understand the process for compiling the firmware I compiled the standard version of the firmware and uploaded it to the TRB143 via the Web UI interface.
Unfortunately, something must have gone wrong as the TRB143 is now completely unresponsive. The 3 mobile signal strength LEDs constantly flash together at ~1sec interval.
I have tried the documented methods for resetting the device and also the method for accessing the bootloader. Nothing seems to make the device responsive.
Has anyone a suggestion or advise on how to recover the device as currently it is a fancy paperweight on my desk.
Thanks in advance…
Hi there,
A further update:- I have tested the micro USB on another TRB143 that is functioning with factory firmware and was able to connect via the virtual ethernet connection. Retested the same setup on the unresponsive TRB143 without success. Is it possible I have missed something in relation to being able to see the bootloader sequence?
Any help would be appreciated as I’d like to understand what happened (went wrong) with the SDK firmware build/upload so that I can avoid repeating the same issue. I am not massively keen in testing the SDK firmware on another device without this understanding.
THanks,
Alan
Greetings,
The TRB143 does not have a bootloader recovery menu. If a standard factory reset (instructions here: TRB143 Device Recovery Options - Teltonika Networks Wiki) does not help, I would suggest contacting your distributor for RMA if warranty is still valid.
Did you follow the instructions provided in the README.md file to build the firmware?

Hi Justinas,
Yes, I followed the READ.ME file to build the firmware. I had previously built the firmware without issue.
By default the TRB firmware appears to build for all TRB14* devices and creates two versions for each. What is the fundamental difference between the two version, from memory as I am not at my development laptop, one version ends in 0 the other ends in 4.
Thanks,
Alan
Hi Justinas,
It appears I have “bricked” the device by uploading the incorrect region firmware version. Checking back through my notes I failed to observe this, must of been distracted.
I presume if the device is out of warranty there is not option for me to recover the device myself?
Thanks,
Alan
