Sure, I am happy to help. Here is what happened if I remember right, but please forgive me, I did not keep a journal. I know I was searching for the manual/guide for doing the update.
(First pro tip, why not have the firmware update guide also linked the actual product. The only link currently that I see on the page of the Gen 2. 28 Pro is the one page manual itself (and the manual is does not contain anthing about updating).
View attachment 590070 Also I would personally think, you could mention about the USB update on the same product page, so incase anyone wants to spend an extra 10-15 bucks to be able to access potential future algorithm improvements (or potential bug fixes), then they at least have the choice to get it now and not later. As it happened to me and I am sure I am not the only one, most people dont even realize there is a such a cable until the need it. Yes, my orginal advice would still be to just include it by default and remove the (only charging cable), I am 100% people would still buy this device if you sold it for 5-10usd more. Then everyone will have the cable. But enough about this, let me continue with recreating the adventure.
So as I did not find the firmware update guide on this product page (yes, I know now that you have that on the USB cables page, but at that time I did not think to look there, rather do what most people in this IT age would to, which is search in google for Sekmet firmware guide or manual or something like that.
This then landed me on this page from your site:
https://www.sekhmetonline.com/blogs/news/user-manual-for-all-the-items As it was your site, I did not read the title in detail. Now iif you open that link, you will see were my new frustration stated to build up again (compounding to the past evets). On that page you can see the titles very clearly. You can click on any of the them (go an try it) excep the one I needed. The Gen 2 28 Pro. So you can imagine the WTF? in my head, why you would have a list of manuals for your devices, where all the others actually links do something, but the one for Gen 2 does not. It says updated Aug 22, 2025. So it should not be an old page.
I guess this is another thing that you could go and fix.
View attachment 590072 Then I went back to google and did some more searches, for how to update firmware. I am not sure how I landed on this page:
link By this time I was getting impatient clearly and completly missed that this did not say Gen-2. and I just saw Pro 28mm and went with it. They reason I tought it was Gen2 cause I know what Gen 1 and its updater looks like, and this "mini" one you have to admit looks just like the gen 2 28pro on this picture. Which is what I saw when I opened the link.
Then I scrolled down and saw the firmware updatge steps, which I started to follow. And in the flowchart you can see it say click the left. Nothing about holding and not releasing till you go back to windows and click next and so on.
View attachment 590075 Of cours this did not work after server tries (the device did not freeze, just kept saying nothing detected). Then I went to search again and found that other thread that I linked, which I tried to follow, however when I went into the link provided in the thread, as I admited in my previous post, I was already quit frustrated about all of this, that I did indeed no read that sentence about holding. I will here again still suggest that you rephrase it as, when you make such guides, it is better to mention anticipated steps in advance, not after the fact. So I would rephrase it to "press and continue holding, do not release, till you complete the next step".
Simply saying press and hold, some (like me) would expect something to happen after pressing and holding for a bit. Cause you know that is how you enter the settings menu of the device, so that can be expected. But of course in this case, no matter how long you hold it, nothing happens, you have to continue to hold while completing the next step.
Anyway so those are some of the links that I used. I hope they will be usefull for you and you can continue to update your site, to have all the right information, where they need to be a so on. Honestly, I would put a link to all the manuals under the "support" that is traditional. In your case, you have a contact form under "support". That is usually under "contact". Of course you could have both. Under "support" put the links to the manuals, some video guides if you have and then at the end of the page, you can say, if you need more help then the contacts...
That would make it all more organised I feel. I hope I was able to help.
EDIT: I have succesfully completed the update now. Thank you again. This unit seems fine now. I will wait for the replacement for the second one to be sent to me from Huma-Air. If I have any issues with updating that one, I will let you know. But I think I should be fine, now that I am pro level at this.
