Newbie NanoVNA-H4 user here with some questions:

1) My unit arrived a couple days ago with firmware version 0.5.0. Is this the latest for the H4 model?
2) Has anyone using macOS with Parallels running Windows 10 been able to flash the firmware? I get the unit in DFU mode successfully, the DfuSe Demo windows app successfully sees the VNA, and I successfully load a DFU file into the app, however when I click "Upgrade" the app just sits there with 0% progress. The Device Manager shows all the correct entries in both DFU and normal mode, and NanoVNA-Saver works fine in Windows.

Thanks!

No, it's not the latest firmware. I'd recommend going to the io.group's
files, go to DiLlard's NanoVNA-H Firmware, go to NanoVNA
v0.8.2_96kHzIF_3.2kHz_sweep_points.rar, and extract NanoVNA-H4
v0.8.2_96kHzIF_3.2kHz_sweep_point201.dfu. There are files in the files
section describing how to use STMicro's software to upgrade.

Here is the latest 'official' firmware update for the H4, it comes from Hugen's own repository.

So - I found my own solution for flashing the firmware using the dfu-util command line interface.

FIRST: I replaced the standard driver using the method here:

Doing this BROKE DfuSe app's ability to detect the device while in DFU mode, but in my case, I didn't care. I couldn't flash anyway.

1) Download and install dfu-util command line utility (see: )
2) Place the NanoVNA in DFU mode (in my case, hold down wheel and power on the NanoVNA - screen goes blank, but power LED flashes)
3) Plug NanoVNA into USB port
4) Get into Terminal (on the Mac) or CMD line interface (on Windows)
5) Type the following: dfu-util -a 0 -D DFU_PATHNAME
(replacing DFU_PATHNAME with your own DFU file. In my particular case I typed: dfu-util -a 0 -D "C:\Users\wcody\Downloads\NanoVNA-H4 v0.8.2_96kHzIF_3.2kHz_sweep_points 201.dfu"
6) Hit return, and the flashing will commence.

With any luck, you'll power on the NanoVNA and see your latest firmware.

Good luck!!!

Thanks afreeangel@. I'm not certain why you posted your reply, but I can only guess that you're hinting that a later version firmware is available.

In any case, looking at your link, it seems to apply to NanoVNA's with an SD Card mod, of which I do not have.

Please let me know if I am misreading your post.

Latest is v0.9.1.0 and it is without sdcard mods.
The v0.9.1.1 is the same as 0.9.1.0 but with sdcard mods.

Excellent! Loaded it up and I really like the GUI improvements.

Thank Bill for this post.

I just managed to update my H4 successfully following your procedure.
In my case I installed Homebrew natively to my Mac, followed by the installation of Dfu-Util.
I then installed Dislord's V1.0.39 firmware and everything worked just fine.
