Hello Team,

What is the latest firmware version currenly available to flash to my unit? I I got it with FWVersion 8 and FWSubVersion 5 then updated it to FWVersion a and FWSubVersion 1.
I faced some issues with connecting it to Lenovo X1 Yoga Gen 6 (it has thunderbot 4 ports) with my displayports monitors. I even tried the hdmi ports for both monitors and it is not consistancy working! sometime it works and sometime not.

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

Please see our KB article here: https://kb.plugable.com/question/1475318 for how to identify which firmware version your dock needs.

Note: There are two hardware revisions of the dock, based on the firmware updater that failed to install or even recognize your dock I suspect you have the Genesys version which is incompatible with the firmware version (VIA) that you were attempting to update to. I believe if you follow the steps in the article above you should be able to successfully update your dock to the latest version!

If you still are unable to update your dock please let me know and I will be happy to assist further.

Thanks again for contacting Plugable support and best wishes!
