Cinema 800 - Firmware Update
Important: If you haven’t already, please use one of the methods provided below to connect your sound bar to your WiFi network. Once on the network, the bar will update the WiFi and MCU (main controller) firmware (if it is not already up to the latest version).
For detailed instructions on connecting to your home network, please see one of our Help Center articles:
If the sound bar has not updated once connected to your home network, follow these instructions to install the Cinema 800 firmware.
Steps to Upgrade
- Delete all existing files from a USB flash drive.
- Make sure drive is 8GB or less and formatted to FAT32
- Follow this link to download the SWU file to the thumb drive.
- If you are using a Mac or iOS device, you may need a seperate program to unzip the file.
- Copy the provided files - and only the provided files - to the thumb drive
- If the files were extracted to a folder, copy the entire contents of the folder, not the folder itself
- Re-name the SWU file to image.swu
- Eject the thumb drive from your machine - Macs require you to drag to the Trash, and in Windows you can right-click and select 'Eject'
- Power on your soundbar if it's not on already
- Remove the side panel to expose the USB slot on the soundbar
- Plug the thumb drive into your soundbar
- Hold the 'Power' button on the soundbar until the word 'UPGRADE' appears, then release the Power button
- Wait about 2 minutes for the update to begin - it must copy the very large update file to the bar, and it shows no indicator while this is occurring.
Wait for the upgrade to complete - the status will be displayed on the soundbar
- It can be a good idea to wait 10-20 minutes, in case the software is upgrading and not showing status updates, which has been the case in earlier versions of the software. It may also flash "WIFI" to indicate it knows it needs to update the StreamUnlimited component.
- Remove the thumb drive
- Unplug the soundbar, wait 10 seconds, and plug it back in
- Power on the soundbar
- Scroll through the versions of installed software to confirm the update has completed.
Note: You can check the various, current firmware version numbers by pressing the small surround pairing button under the right end-cap.
Keep pressing this button to scroll through all the firmware currently active on your device. It should display as follows:
MCU v76 > WIFI 126.96.36.199 > DSP 4.4 > SUR T 80 > SUR R 80 > SUR L 80 > SUB T 3 > SUB R 6 > HDMI 43
