I had the same issues. I used dfu-util, a bit of a PITA but figured it out. You need to follow the how to and also rename the file to what the batch file expects. It’s a DOS based process but mine is running latest and works- passes self test and Cal.?

And Windows 10 needed to recognize the tinySA as a usb device- running zadig helped get it recognized. ?

Good Luck?

I've downloaded dfusedemo, version 3.0.6. With it running, I connect the TinySA and put it in DFU mode, but the application doesn't find it. If it's any help, when I enter DFU mode I get the 'USB disconnect' sound.

I've viewed a couple of YouTube videos, and can't figure out what I could be doing wrong. Also, if I click CHOOSE and select the new .DFU file, the application reports that the file doesn't have the correct format. Seems I have two different issues.
