The problem is as follows:
I am trying to update the current firmware 03.29.00 rev: 358 to FMB.Ver.04.02.00.Rev.602.e using Teltonika.Configurator_1.8.22_E.OBDRefine_R.1 the update process is underway, a window appears that the device firmware has been successfully updated, reboots, and then after connecting to the configurator, the firmware version remains old - 03.29.00 rev: 358
I tried to perform the procedure many times, but unfortunately the result is unchanged.
