This firmware update only applies to the HyperDrive Slim 8-in-1. We have an article for the Pro 8-in-2 here: https://hypershop.zendesk.com/hc/en-us/articles/360038378871-Screen-flickering-with-Pro-Please-check-this-out-. If you have any other model, this firmware update does not apply to you. Pictured below is the Slim 8-in-1:
If you have the latest version of macOS and you've noticed your screen flickering when an external display is plugged in, you may need to update the firmware. This issue was discovered shortly after the release of the 16" MacBook Pro and also affects the 15" MacBook Pro. To complete the process, you will need Windows 10 through BootCamp, or a Windows computer with a USB-C port that can support video. Windows 10 is free to download (see below) and can be used without a license. If you already have it, you can skip the download labeled '(2)'. Once completed, you will notice the screen no longer flickers.
If you are unable to complete the update or choose not to, we encourage you to reach out to us directly at email@example.com if you have not done so already. We would be more than happy to complete the update for you to allow you to have a properly working HyperDrive.

I had this problem with my brand new MacBook Pro 16" and Hyper Drive Slim 8 in one, which was connected with a mini DP to DP to a dell U2412M monitor. The external monitor was flickering every 10 seconds.
I followed these instructions, and the problem is now solved.
Only downside: I lost a couple of hours finding the problem and solution, and you need to install Windows immediately to a new MacBook :'(
I noticed in Windows, the screen didn't have any flickering, before updating the firmware. So it's a Mac OS only problem.
Thanks for the clear instructions!
Followed instructions but get "Initialize GPU library failed".
I need to run Windows to update a product I bought for my Mac?????
Hahahaha this joke ! You must run Windows to upgrade your new-but-broken Mac product !
I'm using a windows machine, and the VmmUpdater software does not find the device. Any other option?
The firmware update procedure was a bit confusing to me .....
I'm new to MacBook and HyperDrive so all the steps in the procedure implied that I would have to install Windows to my MacBook (Bootcamp, etc.), something I have no clue about doing (or desire to do - at the moment)
I have a Lenovo T580 with Windows 10 installed ... with a Thunderbolt 3 / USB-C port
Funny thing is that the Lenovo T580 did not have any Monitor flickering issues with the HyperDrive Slim 8-in-1 HDMI port, only with my 2019 MacBook Pro 16" i9...
I connected the HyperDrive Slim 8-in-1 to the Lenovo T580 USB-C port and ran the VmmUpdater.exe app.
The app would indicate which firmware the HyperDrive is currently on.
I then selected the new firmware leaf_Gopod_V14_1230-SST.eeprom
It takes a few seconds to update.
I restarted the Lenovo T580 and unplugged the HyperDrive Slim 8-in-1.
When the Lenovo T580 was started, I reconnected the HyperDrive slim 8-in-1.
Just for interest sake, I ran the app again.
The app confirmed that the new Firmware was loaded.
I then connected the HyperDrive to the MacBook.
I can confirm no flickering issues observed since the updated firmware was loaded.
It would be easier to update the HyperDrive Firmware via a Windows Laptop/PC with a USBC-C (graphic capable) port, instead of the MacBook Windows 10 Bootcamp method.

This is a pretty poor excuse for a solution. I'm not going to jump through hoops because you can't put out a firmware update that will run on OSX. Instead, i'm going to never buy anything from your company again. I buy a lot of devices for Macs through you as I'm an iOS engineer that runs several teams at an enterprise software company. I will also stop recommending your products.
