Answer to "Update firmware usein PC"Just fixed mine with same issue. Follow this sequence: 1. Turn the device on while connected to charger 2. Press the call (phone icon) and the volume up (+) button at the same time and keep them pressed. After a few seconds the speaker will shut down. 3. Release the buttons. 4. Turn the speaker back on. It will automatically enter into search mode... And there you are, memory wiped up. I then did the firmware update.
