EDIT 3: (June 20, 2020) My SoundLink seemed to stop charging. The orange light would pulse, then it flashed red, then it went solid red.
SOLUTION: A new USB cable! The included Bose dock didn’t charge it, nor did my regular cable that has always charged it over the years. A NEW cable did it!
EDIT 2: Another thing to try is to let the battery run out completely. Then it seems it’ll recharge properly. You can drain the battery a lot faster by turning the volume up. It’ll show the red charging light for a while until it turns itself off, then put it on the charger.
EDIT: BOSE has removed the previous version of the software from their page.
There’s still a way to downgrade it by following these instructions!
To reset it, which seems to work in some cases;
- Plug the speaker into power.
- Hold the mute/multi-function button down for 10 seconds (lights will flash).
- Unplug the power cord, then let go of the button.
- Give it a second, then plug it back in to power.
- If that fixed it, good.
- If not, go to the updater site and apply the same version of the update as you already have – or use the hacked updater to downgrade-then-upgrade yours.
The Bose Soundlink Mini II, one of the best bang-for-the-buck purchases I’ve ever made (along with the Dyson V8 Absolute) finally started to show its age.
I got the dreaded charging warning!
The battery should last far longer than a year, so my issue was likely with the firmware. It was the latest version, so I had to experiment.
What ultimately seemed to fix the charging issue was to downgrade the firmware, reset and reboot the Mini, then upgrade the firmware again!
1, Connect to http://btu.bose.com
You might have to download the little updater software which will then prompt you to connect the speaker.
2, Once your speaker is connected and it shows you what firmware you have installed, and eventual updates, press the following keys in sequence on the keyboard
[a] , [d] , [v] , [up arrow] , [down arrow].
This will unlock the “advanced menu” which allows you to downgrade your firmware.
At this point, try to charge the speaker fully overnight and see if that worked.
This worked for me. Once the speaker was charged, I updated to the latest firmware again and it’s been good ever since.
If it does NOT work, then update the firmware to the latest version and try again and that should do the trick.
