HMD Firmware update/recovery error

I have big problems after HeadsetMarker Firmware update to v2.1.
When connect  the HeadsetMarker to the PC, the light flashes orange once, disappears and can not be used/paired.
NOLO-Software shows;  Connection Status with "Hmd: connected".
But now the HMD can not be paired with the Base-Station. 
I have tried to perform the FW upgrade/recovery mode, but the
NOLO-Software always show: "not connected".

  • Hello. I think the same happened to me. I have Pimax 4K and NOLO VR. I had some problems with the controllers and decided that I need to update the firmware in order to get rid of them. When I installed the nolo drivers and the utility, I clicked the firmware update in it. After that, the device ceased to be recognized in the system. I sent you my serial number. Please help me! :(
