NanoVNA H4 Firmware Upgrade

It is a rainy day so no POTA or any other outdoor radio fun. So today I decided to make a quick video on how to upgrade the firmware of your NanoVNA H4.

There were some hiccups but I show you how to get past them.

Latest NanoVNA H4 Release:

Latest DfuSe USB Device Firmware Upgrade (UM0412)

Direct Link to DfuSe USB Device Firmware Upgrade (UM0412)

Perfect instructions. I just updated my Nano VNA-H . Your instructions were spot on! Thank you!

I couldn't get DFUsedemo to see my H4, so tried STM32CubeProgrammer which would, then the NanoVNA would do anything! Nothing I did would unbrick my H4....then watching your video yet once again, I decided to delete the STMbootloader that appeared under the "extra" Universal Serial Bus controllers in device manager (hey I bricked the Nano, why not brick my desktop computer, LOL). When I went back to the DFUsedemo, it now saw the H4 in DFU mode and in the device manager I again got an additional Universal Serial Bus controller that now had a device in DFU mode! Then I was able to update to dislords 1.2.29 firmware via you instructions and it began working again! Thanks soooo much for the time you took to put this together. W4FLI

You are a rock-star for providing a direct link to that DFU software. One less email capture to deal with. Thanks for taking one for the team.

Just updated a new NanoVNA H4 to version 1.2.40 Build Sept 6 2024. Had all the issues illustrated in the Video and all resolved as shown. Very Good.

I spent several hours on a Mac M1 running a Win11 emulator. I could not get the DFU Driver to load in any way. Mac emulation using Parallels 19 is a no go.

In frustration I dug out an old Win10 pc and it loaded up right away! I updated my -H4 from 1.2.14 to 1.2.20 like a boss! Lots of new functionality was the reward.

Thank you!

Well done Matt, a proper and succinct set of instructions without the BS. Keep it up my man.

Thank you for this detailed video! I kept crashing my head against the wall doing this on my own. Then I watch a dozen or so other videos until yours came up. I watched it and did everything step by step back....watch again...etc...) But thanks to you I finally did it on Windows 11. Great job and keep make great content.

Thanks for the NanoVNA Firmware Update video. I followed your description step-by-step and completed the process successfully. 73

I downloaded the dfu file for the Nano-H and then followed the process to download the STM Demo files and ran into the driver issue as you explained. I was able to resolve the issue following your steps to point to the installation folder where the latest driver was installed. The software immediately recognized my Nanovna-h and I then pointed the software to my DFU file. It took over 35 minutes to complete the Erase Phase. It then proceeded to the Downloading Phase and then errored out at about 27% completion.

I am retrying everything from the beginning and hopefully it will successfully complete the Firmware upgrade. if not I have a brick.

PS: I made sure that I downloaded the Nanovna-H dfu file NOT the Version 4 file.

I was able to complete the upgrade after running the Erase Module a second time. I had to let it run overnight as it took awhile to complete the Firmware upgrade. I am currently running 1.240.

as a brand new user, i followed every step... but no joy... thank God im bald, i would have pulled my hair out.... the ONE step that you didnt cover that i found out the hard way was to consider the NanoVNA DRIVERS!!!! try as i might, nothing happened. only when i looked into the NanoVNA io groups, it talked about drivers... after i did that, did all of your directions made sense.. i had to use the win 8 versions for windows 10.... and yes!! i was successful with upgrading the firmware like in your video!! Great VIDEO, except for that one little step.... lol

Thanks for taking the time to produce this video. Worked perfectly! Jack N3DNA

Great video! Upgraded my H4 with no issues following your instructions.

Thank you so much for this, i used it to update my old one which seems to have fixed it. I also replaced both of the sma connectors because they were getting loose. Just some advice if you do replace the connectors, use some heavy sidecutters or nippers to chop them up (carefully not to damage the board) first. Its much easier to desolder the 5 pins individually than dump a ton of heat and pull them all at once

Awesome simple to follow video - thanks so much for posting.

Updated my NanoVNA-F V2 with the wrong version of firmware it went dead dork screen and I can't see the U disk icon on my desk top to rload the firmware any Help will be much appriciated Thank You

[andrejpisljar]

Thank you so much. Great instruction. Works like charm. Greetings from Thailand.

Couldn't see the unit in Dfuse like you showed in Device Manager it was in the USB device section but the driver installed was the latest anyway so I tried the STM32cube software shown in your video instead and that worked but with the .bin file instead of the .dfu. Thanks for the links to the upgrades and the hints to overcome the driver hiccough 👍

[tghaffar]

Thank you for the excellent instructions which I used for upgrading my NanoVNA-H

A year later, March 11, 2024. Firmware and Installer versions are still the same as in this video. Thanks for doing it.

You sir, are my Guru. I am not worthy but thanks. That problem in program manager was my downfall
