  • Go to “Settings > System > Check for Updates” on the Vizio SmartCast mobile app.
  • Select “Yes” to confirm your choice to check for updates.
  • The sound bar will power off when an update is available. It will download the new firmware and install it automatically.
  • The update process can take up to 30 minutes. Take note that the connection to the SmartCast app to the sound bar will be lost as the update is being installed.
  • Once completed, the power LED will remain on and the SmartCast app connection will be restored.

NOTE: Do not manually turn on the power on your soundbar during the update process. Once the update is interrupted, you will need to perform the process from the start. Also, make sure to keep the sound bar connected to the power during the update process.

If your Vizio sound bar is not downloading the update through the SmartCast mobile app, then you can try to manually download and install the device software update.

Were you successful in updating the firmware on your Vizio soundbar? Let us know in the comments below which new feature you enjoyed most.



  1. Tried everything that I can on the internet and it still won’t connect. This should be easy, why is it so hard?

  2. First I don’t even have a wifi setup option on my remote. My soundbar hasn”t worked well since day 1. The fact that there is no support willing to help only makes it worse. Very snarky reps on phone!

  3. Same unnecessary frustration here. My remote isn’t even close in appearance to the one featured in the smartcast app.apparently, every avenue I take in order to update the firmware of my m-series soundbar arrives at a dead end. Very misleading and inaccurate information on behalf of Vizio.
    If your company provides a service, then fulfill it; accurately and easily.
