If your Bose Smart Soundbar 900 is stuck, unresponsive, or having firmware problems, you can enter recovery mode using the physical buttons on the soundbar. Press the Action and Microphone Off buttons in the required sequence until the LED bar blinks green.
Below, we’ll show you exactly how to put the Bose 900 in recovery mode, how to confirm that it worked, and what to do if recovery fails.
Quick Answer: Bose 900 Recovery Mode
To put your Bose 900 in recovery mode, press the buttons on the soundbar in this exact order: Action → Microphone Off → Action → Microphone Off, tapping each button once with about one second between presses. When done correctly, the LED light bar will blink green, confirming that the soundbar has entered recovery mode and is ready to download and install the latest update.
How to Put Bose 900 in Recovery Mode
If your Bose Smart Soundbar 900 is unresponsive, stuck during a firmware update, or experiencing software problems, recovery mode can help reinstall the latest firmware.
The process uses the physical buttons on the soundbar and does not require the remote.
How to Enter Recovery Mode
1. Power Cycle the Soundbar
- Unplug the Bose 900 from the power outlet.
- Wait 30 seconds.
- Plug the soundbar back in.
- Wait for the light bar to turn on.
2. Enter the Recovery Mode Button Sequence
Within 10 seconds of the light bar turning on, press the physical buttons on the soundbar in this order:
Action → Microphone Off → Action → Microphone Off
Wait approximately 1 second between each button press.
Do not press the buttons rapidly or use the remote.
3. Confirm Recovery Mode
If the sequence is successful, the light bar will blink green.
A blinking green light indicates that the Bose 900 has entered recovery mode and is ready to attempt a firmware recovery.
The soundbar will then attempt to download and install the latest firmware automatically.
What Does the Green LED Mean?
A blinking green light bar indicates that the Bose Smart Soundbar 900 is in recovery mode.
During the recovery process:
- The soundbar attempts to download the latest firmware.
- The light bar may scroll white from right to left while downloading.
- It may scroll white from left to right while installing.
- The update can take around 20 minutes.
- Do not unplug the soundbar while the update is running.
When the recovery process is complete, the soundbar should restart. You can then open the Bose Music app and reconfigure the soundbar if necessary.
What to Do If Recovery Mode Fails
If the green LED does not appear or the firmware recovery does not complete, work through the following steps.
Green LED Does Not Appear
If the soundbar does not enter recovery mode:
- Unplug the soundbar and wait 30 seconds.
- Plug it back in.
- Wait for the light bar to turn on.
- Within 10 seconds, press:Action → Microphone Off → Action → Microphone Off
- Wait approximately 1 second between each press.
- Make sure you are using the buttons on the soundbar itself.
If the green light still does not appear, repeat the sequence and continue alternating the Action and Microphone Off buttons for up to 30 seconds.
Recovery Starts but the Update Does Not Finish
If the light bar continues scrolling or the firmware update appears stuck:
- Leave the soundbar powered on.
- Make sure the soundbar has a stable network connection.
- Allow sufficient time for the recovery process to complete.
- If available, connect the soundbar directly to your router using Ethernet.

Avoid repeatedly unplugging the soundbar while firmware is being installed.
Soundbar Is Stuck in a Boot Loop
If the Bose 900 repeatedly restarts or remains stuck during an update:
- Unplug the soundbar.
- Wait at least 60 seconds.
- Reconnect the power cable.
- Try entering recovery mode again.
If the problem continues, use the manual firmware recovery procedure or contact Bose Support.
