NanoVNA H4 Firmware Upgrade 

Thanks for sharing....Worked exactly as described

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

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.

Thanks, today your update instructions worked flawless.

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 (pause...start....pause....rewind back....watch again...etc...) But thanks to you I finally did it on Windows 11. Great job and keep make great content.

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

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!

Worked perfectly - thank you for clear instructions!

Finally! A detailed guide! 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

Great instructions! Simple and to the point.

Thanks your instructions, was perfect .

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

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

thank you very much. perfect video, easy to follow.

Perfect Video! Thanks

Great video! Was able to update mine easily!

☝👍💯❤❤❤❤❤ I had the exact same problem and couldn't find a working solution anywhere. Luckily I came across your video here. Now my NanoVna H4 is running fine. Many thanks and best regards from Germany, Michael. 73´s

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

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

thank you my friend, good job!!!

Dude thank for direct link and clear explanation. It's so easy to update the firmware. 73

Man, you saved my sanity! Thanks for that trick.

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

Thanks for the video and glad I watched until the end. The upgrade went smoothly but it looks like you have the same issue that I did which is a huge spur just above 300MHz. I fiddled with the with the expert settings to knock it down. Any thoughts on how you may have addressed it?

u did my day bro thx so much! 73

Thank you very much much appreciate it

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 👍

very very thanks !

Thank you!!!!

Thanks!

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

Outstanding instructions. Thank you! 73 KB3WAU

Wow, Thanks for this. I guess I need to just break down and learn how to use my H4. Mine was on version 0.5.something lol. Quite a few more options now with the newer firmware. I keep thinking I want to buy one of those Rig expert stick pro's but that $ just keeps me from it. suppose I'll learn this thing finally and probably have everything I need. Thanks again.

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

Thanks, 73 from PY Land.

Wil it work on the 2.3inch "H" 1.1 version please?

hi, perfect. where can i set the date/time?

Hello my friend, I have a VNA 4 want to update the program. No, you found it difficult to know the computer. Is there a program to identify the computer? Thank you.

i have the bootloader updated but the nva still won t show the stm dfu in manager

Hi, I'm 4S5SC, Udaya from Sri Lanka. My namovma is not bootup. Battery is okay. What shall I have to do?

Went through the process and it completed fine however, when I disconnect and power the VNA on again, I no longer have a display, just a black screen. This is the SeeSii branded H4. Is it possible this needs a different file? It was using 1.2,14 like your was before I attempted the update.

I just got one says it's the upgraded version HW3.6 not sure what that means

Just got my H4 last week and followed your excellent instrucitonal video on how to upgrade the firmware. Just curious, is it normal for this device to freeze up occasionally when depressing the thumb wheel? It brings up the menu but freezes.

Weird, takes 40 minutes to an hour to flash - I did the first two with the normal USB cable then my friend said his took one minute with the USB-C cable so now I am trying with the USB-C and it is still taking at least 40 minutes. Any ideas why? I have a very fast laptop.

Thank you for a great instructional video and supporting info. I do have an issue you may wish to help me with. I ran the upgrade as directed and get positive confirmations on all steps. However the unit a Zeeenko Nanovna H4 is not accepting the upgrade. I tried the .bin file as was suggested in the comments. Any help appreciated.

Thanks for this instructions. It made it really easy. One question though to people that have upgraded to this latest v1.2.20 I notice that setting the Reference Level through menu does not work right (or I am doing something wrong). If I choose the expected Reference of about 0dB or something similar I get most strange big values it sets the Reference level to, like 100. The Scale/Div also messes up, sometimes goes to 0. Has anyone else experienced the same issue. On the other hand, setting the Reference level by touching most left up or most left down changes the reference level by one Scale/Div at the time. .... I will search the web for more clues..

Oh, crap...I did the upgrade, program said it was successful, but....when I turned it back on all I had was a blank white screen. Power cycled a few times, same result. I think it's bricked....

Excellent explanation that I have carried out with success. You are a teacher. Like and subscription to your channel. I liked the wallpaper that you have and I would like to know if it is possible to get it. A cordial greeting.

Unfortunately mine does not come back up. Stays black just like it did when in DFU mode though it isn't. I even plugged it in and the software didn't recognize but I redid the start with the jog button pushed and the software did recognize it so it was not stuck in DFU mode. Two possibilities I think. Mine has SeeSii up in the top right corner and perhaps that brand has some incompatibility though the software and versions matched exactly. Another is that I found two DFU files that could be downloaded at the link and did not know which one. I tried the larger one first....when it stayed black I then did it again but this time with the smaller file (84kb) It did go through the erase mode and upgraded successfully...but is staying black. I think it is me....I have this effect on electronics ;) I still thank you for sharing this info and you even put links in. Very kind. thanks.

My NANOVNA not switched into DFU mode

You at no time said it was windows only. Great help.

just got mine. How can i get its display up on my laptop screen for viewing as I have bad Eyesite

Can you please provide a link to your wallpaper background?!?!?!

HELP!!! mines stuck in dfu mode wont come out

litevna 64 cant update.. manual driver selection not help

well I asked a question and part of the answer showed up in my notifications but i cant read the rest of your answer and now my question has disappeared from the comments on this video

ok but WHY upgrade it? any real useful purpose to do so?

🙄It is GENUINE! Is NOT a COPY, is NOT a CLONE is NOT a FAKE! Is just made by ZeenKo! (4.3_MS means it's have MS5351(new) vs Si5351(old) watch to firmware update!)

Did everything and got same messages as you after upgrade was completed. Turned off then turned on but nothing just a black screen and a message saying device USB not recognized! It's as though it's bricked! What next? Buy a new one? Arrrrg! It's an H4. Update...problems resolved...go to Matts video of how to get out of DFU mode. Don't forget to push button down!!!

man this takes a bit going on 20minutes
