TB16 Firmware update. --- return 0x205

Hi,

I'm using xps9310 with a TB16 dock. I want to perform a firmware update for TB16 with utility 01.00.04.

I have tried servel workarounds found from the forum, using local account, disconnect all devices, but without success.

This is the log that I got with the firmware update utility.

i got error information as:

Attempting Dock NVM executable firmware update

and this is screenshot of firmware update utility.

Thanks in advance.
