Ya it would have been great to follow any of the tutorials that just say to click on DFU in the config file.? I was a painless upgrade.
But if yours is like my unit, there is not DFU choice? in the config menu.
And Holding down the joy stick while turning on was not the simple answer.? IT may have turned DFU on but it was not seen in the ST32 app.

So at some point someone will figure out a easy upgrade for those of us who are not CMD literate.
I am a Ham Radio operator - not a computer? wize.
?Tried runningn the TinySA app..... but it did not detect my TinySA Ultra either.

? ?Its been ages since my first tinySA installation and I didn't need to do anything extra after adding TinySA Ultra to the mix. I recently set up a new Windows 10 PC and documented the steps I used to establish connectivity with my tinySA Ultra. The attachment contains all the directories and latest firmware I used during my installation.

1. Extract the attached file to the C: drive.??
2. After extraction, a top-level directory named TinySA Ultra with subdirectories named /DFU, TinySA-APP, and WIN10 Driver should have been created.
3. Connect the TinySA Ultra to a USB2.0 port on the PC (USB3.0 also works on my computer, but other users have reported connectivity issues).
4. Power on the TinySA Ultra and you should hear the Windows sound indicating a connection was detected.? A message should popup saying a new device was detected and Windows was installing a driver for it.? This message only appears the first time the tinySA Ultra is detected.? Wait until a message appears saying installation is complete.
5. Go to the?C:\TinySA Ultra\TinySA-App directory and run?tinySA-App.exe.
6.? Click on the drop down box with the "None" entry and select the COM port for the tinySA Ultra. The correct COM port is most likely the last entry in the drop down box.
7. After selecting the correct COM port, select the "Disconnect" button opposite the COM port drop down box and it should turn to "Connected".? To test connectivity, select the camera icon and a captured Image from the TinySA Ultra should appear in a separate window.? This confirms the serial port is working correctly.
8. Turn off the TinySA Ultra.
9. Load the DFU driver by going to?C:\TinySA Ultra\WIN10 Driver and right clicking on "STtube.inf" and selecting install.
10. After getting a message that the driver was installed, switch on theTinySA Ultra while holding down the thumb wheel switch. You should hear a connection detected sound from the PC and the TinySA's screen should remain dark indicating it is in the DFU mode.
11. In TinySA-App click on the two up pointing arrows (^^).
12. A firmware update box should appear saying DFU Device opened and closed.
13. Select the upload firmware icon. When the file selector box appears, use it to select the DFU file at "C:\TinySA Ultra\DFU\tinySA4_v1.4-79-g0db995c.dfu".??
14. After selecting the DFU file, updating to the selected version should begin. Wait for it to complete and select the "LEAVE DFU" button and the tinySA Ultra should reset and exit the DFU mode.

This installation procedure worked for me. I hope this helps other users performing a first time Windows 10/11 installation.??
