Wanted to add details to my post. thought I was makng a heading....
Anyway my Bose revolve does not charge. When I plug it in to charge, I get a tone, then the battery light blinks yellow forever. Tried other USB chargers as well, no luck. Less than a year old and it is already a brick.
Thank you for posting in the community, you've come to the right place! Let's try a reset of the speaker, I have included the step for you below:
Unplug the speaker from power and turn it on. The battery must be charged to do this.
Press and hold the Multi Function Button for 10 seconds.
Release and try the speaker again.
If the rest does not help then I would recommend that you reach out to customer support here. Just select your country and scroll down to where you see "contact us". When you speak with support you'll be able to get more information on what your available options are.
