The Bose Community Forum was launched at a time when robust online support was not available for Bose customers. Over the past several years we have added new online service channels that provide a more interactive and complete digital experience. Additionally, we have enhanced the My Bose Account capabilities to deliver a more personalized and self-service experience. As a result, Bose has made the decision to close Community Forum for Consumer electronics products on September 30th. The Bose Pro portion of the Community will still operate as usual.
Please visit our support homepage to experience one of our many other digital service channels or simply use your Community log-in credentials to sign in to your My Bose Account to view your orders and view support options.
Thank you to all who have contributed and benefited from interacting in our Community. We look forward to continuing to serve you online.

Is there a way to DOWNGRADE SoundLink Mini II firmware please?
A few month ago, I successfully downgraded firmware using Bose Firmware Updater.
Now, It shows only version 1.1.4.
Thank you for posting and welcome to the community.
What you may be thinking of when you mention that changing the language helped previously, is we do suggest resetting your speaker as a way of troubleshooting any charging issues. During this process, as it does clear out previous settings, it will ask you to choose a language again, so this is likely what you did before.
To perform the reset what you would need to do is turn on the speaker, then press and hold the power button for 10 seconds until the speaker turns off. When you turn it back on afterwards it will ask you to choose a language as you found before.
Another thing I would recommend doing, if you haven't already, is putting the speaker into 'Ship Mode' and attempting to charge it then. To do this we need to:
After doing these steps we should let the speaker charge for at least an hour to see if this improves the charging.
Should your issue still persists after the steps we have recommended above, there may be a hardware fault with your system. As a result, I recommend getting in touch with our customer service team via clicking this link, then kindly scroll and select your region, once this is done please scroll to Contact Us. The team will be on hand and ready to help.
Thanks for the post, and welcome to the community.
There is no way to downgrade or revert the firmware on your Soundlink Mini II.
Is there a reason why you want to downgrade? Are you having an issue with your system?

I've been unable to use my Bose Mini Soundlink || speaker since the middle of the summer as for some reason it stopped working. I was talked through the upgrading software process and completed it, to which it now has the 1. 1. 4 software. However, it has stopped working yet again and i haven't the slightest clue why. Very disappointed considering how much the product cost and how much i've promoted the product. I have only had the speaker two years.
Thanks for the post, and I'm sorry to hear about the issues you're having with your SoundLink Mini II.
Are any of the LEDs lighting up on the top?
Can you try THESE steps and see if they help?
Let us know so we can get this resolved.

*** SOLVED ***
Here's what solved my problem finally.
The following last resort worked for me to solve the red flashing light issue:
1. Download the software updater package
2. Connect the speaker to your computer with the USB
2. Go to the http://btu.bose.com site
3. Wait until it connects to your speaker and gives the software version
4. Whatever happens, you need to update the firmware (either upgrade or downgrade). That's what does the necessary reset.
5. To go in advance mode, you need to press these keys in order: 'a', 'd', 'v', 'up arrow', 'down arrow' and all of a sudden alternate versions appear OR at least for me, a couple other things appeared. I wasn't able to change the version BUT, changing the language simply did the job and the software actually started being downloaded.
7. At about 80% you'll see the red flashing light go orange and there are beeps and things
8. You're done.
9. At the end told me that the device can't start the update since the battery is too low. I just unplugged it & hooked it to the charger to be charged.
I checked this solution 5 minutes ago and it worked. I am quite disappointed at Bose as always thought they're good. But this product & battery protection mode simply suck especially, since the cost of sending it to be serviced by them is higher than buying a new one right now.

So I've done all the steps above and all the button resets. And stilll haven't worked for me.
Funny thing is that the speaker works for a while, and then falls to the blinking red light mode once again.
While those 20-30 seconds that it's alive - it's saying that the battery is at 100%. So i wonder why does it revert back to red blinking light ?
Answer was in the log - of the advanced installation page - Serial number dont match.
As i figure - 1.1.4 firmware has a bug. Misreading the serial number of the device to the battery, which breaks the charging process.

Thanks for posting. You might also try factory defaulting the speaker with THESE steps. Beyond that, if you continue to have power issues please contact Customer Support. Contact information can be found here. Just select your region, and kindly scroll down to where you see "Contact Us".

So that's what i've done also - contacted support. Answer was - needs to be serviced. But it is clearly a software issue. Which makes no sense to me.
I've also tried the reset you mentioned. This while breaking the firmware update procudure to make the speaker work for a few moments. But same result - speaker works for 20-30 second just fine. Then blinks red light and thats it, doesn't respond after that.
Can you let me downgrade to 1.1.3 and see if it helps ?
