Reset tmt250 frimware

can you help me, since the firmware update, my TMT250 shows not supported when I connect it to the configurator. What can I do to get it back into service?


If the firmware is updated on the device, use the configurator that is attached with the same firmware file.
In case device is updated and an old configurator is used, the device will display as “not supported” when attempting to connect it to the configurator.

Download latest configurator from the Teltonika wiki website.



sorry to bother you again, I’m sure you’re busy. But your last advice did not produce results and I have the impression that the firmware version is that of another model. the TMT250 has a configurator 55.02.03.Rev.05 but the device version is 03.29.00.Rev.18
