This morning, Fri. July 14, Updated 3 speakers, 2 20's and 1 30 and 2 out of three made it but one is stuck with the progress bar full. The 2 + Vol down setup does not work. power holding does not work. Access through the app doesn't work. I have unplugged power in hope when the battery dies I can bring back to life.
Sorry to hear about the issues updating your system.
The SoundTouch 20 does not have a built in battery, so removing the power cable for ~30 seconds should be enough.
Let me know if this doesn't resolve the issue.
Sorry, my reply was incorrect, The ST10 also does not have a battery, it's the same as the ST10 & ST20, it needs mains power.
the ST unit that is battery powered is the ST Portable.
My mistake again, the 3 ST units that are mains powered with no battery are ST10, ST20 & ST30.
The battery powered unit is the ST Portable which is no longer available AFAIK...
Do you have a serial number for your product? It should be located on the back or on the bottom, and will contain 16 or 17 digits. This will identify exactly what product you have.
