Bose Smart soundbar 300 stuck in updating mode


My Bose smart soundbar 300 is stuck on updating. Whenever I turn it on, it always gets automatically to update mode. I have tried rebooting it and resetting it multiple times, it is always stuck on update mode where white lights are going from left to right. I can't get it into factory reset mode. I also tried to get my speakers into recovery mode, which I can do it but after that when it starts to update the device again, it is still stuck on update. I also tried to manually update my soundbar but I always get the following error: " Opps, that didn't work. Download a different file then try again".

Please help me with this.

Thank you.

Hi Rohanj.0606, 


Thanks for posting and welcome to the forums. 


I would love to help you get this resolved. It looks like you may have exhausted all troubleshooting. Can I please confirm, did you use the steps here to put the speaker into recovery mode? If so, as you have tried all troubleshooting steps, the best option here would be to reach out to your local customer support center and explore the service options for your system.
