  1. In the programmer app, Select the port number you noted down above using the dropdown menu in the top of the window.
  2. Click the "Connect" button to the right of the dropdown menu.
  3. After a moment, the circle to the right of the dropdown will turn blue, and the "Disconnect" button will light up to show that the app is connected. On the speaker itself, the "PAIR" indicator in the top right of the interface will also light up.
  4. In Windows Explorer, unzip and select either of the two firmware-files (download)
  5. Press "Write" in the bottom right corner.
  6. Wait for the writing process to finish (see the progress bar in the bottom)
  7. Verify that the file was transferred correctly. The circle to the right of the "File" input box should light solid blue after writing. If it's flashing after the firmware update is finished, it means the transfer failed. You can also verify that the firmware name appears next to the "Main Board" and "LL_Module" rows, in the text box in the middle. These two lines shows which firmware is currently in the speaker.
  8. Repeat steps 4 to 7 with the second file you downloaded here. Note that one file takes about 30 seconds to transfer, the other takes about 2-3 minutes.

Do not close the programmer app, the PC, or the SOWA speaker while firmware update is in progress. Make sure that the SOWA speaker has at least one red line in the battery indicator, and that the line is not flashing. If so, plug in the power supply.
