Hello, try this method.
Update a soundbar through SmartThings
Connecting your soundbar to SmartThings allows you to control it from your mobile device. You can change the volume and connect your speakers to a synchronized surround sound system. You can even play your favorite song every time you open the front door.
Step 1. Make sure your soundbar is connected to the Wi-Fi network using SmartThings.
Step 2. Open the SmartThings application on your mobile device and select the soundbar to access its control menu.
Step 3. Tap the More Options icon (three dots) in the upper right corner of the screen.
Step 4. Select Information, and then tap Firmware Update.
Step 5. Tap Update Now. Keep the Automatic update switch on if you want to use the automatic update feature.
Step 6. Follow the instructions on the screen until it indicates that the update is complete.
All the best.
