Re: Firmware 4.5.2 QC35 ii
After updating my QC35II headphones to firmware 4.5.2, the Action Button, which is configured for "Noise Cancelling", does nothing nothing but beep. Prior to 4.5.2 the Action Button would cycle through noise cancellation off, low, high with each level having a distinctive beep. The Action Button now does nothing but make the "high" beep without changing the noise cancelling setting. The only way I can change the noise cancelling setting is via the Bose Connect iOS app.
I originally updated my QC35II headphones through the Bose Connect iOS app since it had automatically downloaded the update. When the update had completed and I noticed the Action Button no longer worked, I found this thread and I tried performing the update using the Bose Updater on my PC. The updater told me my firmware was up to date but that my voice prompts needed updating. I performed that update, but still the ANC button does nothing but beep.
How do I get the ANC button to work again?
