Holybro Sik telemetry solid red light, unable to update firmware


I have Holybro Telemetry Radio. It has a solid red light which indicates that it is in Firmware update mode but I haven’t been able to update the firmware. I connected the GND of telemtry radio to CTS and connected it to QGC through USB. It recognizes the SiK radio but it gives an error; Unable to put radio into command mode +++.
