Read this topic about the firmware update problem: [Firmware not supported on this device (TRB500)](https://community.teltonika.lt/t/firmware-not-supported-on-this-device-trb500/7205)  
This also has a hint how to update the modem firmware.  
Try to do them both (first the main firmware then the modem firmware)
