Downgrade Sonos Port from S2 to S1

There is another benefit of remaining in the quiet S1 backwaters and being of no interest to Sonos. 

I am seeing some threads referring to EULA that posit that Sonos may be taking control of your Sonos kit via the new courageous app. Even if they are doing this via a new EULA, this is still a heist. 

Stay on S1, present version; don’t even update within S1 and I don’t see that Sonos can then steal your speakers from you by taking control of them via the new app.

All update privileges for Sonos have been locked down! 🤓 I only recommended Sonos to one of my friends.. ok… I only have one friend 😜… and I feel sorry for him as he has Sonos at all 4 of his home locations and he uses an iPhone.. but I think he will be ok as he only listens to Spotify so he should be able to just use the Spotify app for most of his day to day operations.  😎

The other GREAT thing about S1 vs S2… NO MORE ADs!!! I hated the popup ads on S2. I would go to my tablet to skip a song or adjust the volume or group rooms and there would be a GIANT AD “Listen to Holiday music for that festival mood!” or “The latest Sonos Product model CR7#5#%3*2AP is here!” “Come spend your money on it! Click here!” 

Not seeing that crap anymore!  Oh the joy! 😁🤘🏼

I have now tried with your exact steps but it is now impossible to revert back to S1. Everything in your screenshots works just until after you have selected the device to downgrade to S1, it needs to check if it is the latest version. I have tried blocking Internet access etc but it will not pass if it can’t check and will not pass since it is not the latest version.

I guess you made the downgrade in the exact right time.

What happens if you factory reset the unit and have it be discovered by the S1 app?

It sees it but it says it can only be added by an S2 app.

Tried with Mac OS App by that can’t do anything, nor adding or downgrading.

Hmm. I have no experience of this because I have never moved beyond S1. Are you running S1 just now with other units or are you fully on S2? 

I wonder what would happen if you had a brand new Port and wanted to set it up on S1...

What version of the Sonos S2 app were you on before trying to go to S1?

There was a release after 80.0 which I heard is:  80.00.08 which I believe included a firmware update to the hardware itself so if you are running anything above 80.0 you are most likely locked out of going to S1 until Sonos releases an update to let you do so. 

In the same situation, I tried to load an old version of the Sonos app on my Android phone through Apkmirror to downgrade from S2 to S1, but unfortunately, during the process, it checks the version and gets stuck on 'Update the App,' making it impossible to proceed.
