Unable to downgrade sonos one (g2) to s1 compatible

It’s now possible to downgrade, but i have no succes so link the speaker to the S1 app. It always asks to update the app when i want to add a new speaker and that’s the S2 app. So there is no way you can add the speaker to the S1 app, maybe i’m doing something wrong, but i don’t know what?

SUCCES!!! 
After downgrading through the S2 app, you must remove the Sonos S1 app. You cannot install the downgraded speaker to the S1 app like it does say in the S2 app after you downgraded. So, delete all apps from Sonos, install the S1 app and you can add the speaker as a new product. Only problem is, that all the speakers must be reset and added like new products. 

The sound is so much better on the Sonos One in Stereo setup whit the S1 software. Now i going to enjoy them like before. I made sure that the auto update is off and i hope never to encounter this problem again.  

Downgrade now possible but annoying to do. I found that you had to switch off all S2 app products apart from the one you were downgrading to get it to work and add to S1 app

once all done you also need to disable and then re-enable the Alexa Sonos skill to get it to play music on voice commands 

The old way through the S1 app was easier. I hat to reset all the speakers even the one that hat the S1 software to get them all connected to the S1 app. But it was worth doing all the work for it. All the people that visit meanwhile did hear the change when i played music. It’s much warmer and more detailed. 

Hi all.

I’ve been reading all your comments above and looking at trying this myself.

Firstly I found an old phone that’s got the old S1 app….but its a Samsung S6 so not sure if that’s usable device for this?

Before I read your comments I tried downgrading through the S2 app but after resetting and finding my Playbar during the reset it just constantly said ‘your mobile device couldn't connect’ so I gave up.

I know there’s instructions above as to how to downgrade but is there any one who can advise me in “old man” steps?!?

Many thanks

Paul

Hi Paul,

it does not work whit the iPhone 6s, i did try it a couple of times and you really need the S2 app. But whit the S2 app you can downgrade to S1, just reset your speaker to the factory settings. Downgrade the speaker and after that you need to remove the S1 and S2 app. Download the S1 app and you see the speaker you downgrades. BUT, you wil not see the other speakers. The problem is, that Sonos thinks that the other speakers are connected to a other system and that’s why you cannot see the other speakers. You have to reset all other speakers and then just do the steps to add them to the S1 app. I did do the same and all my speakers are now added to the S1 app and all works great.  

Many thanks for the reply.

Is your suggested setup the same as what I tried earlier:

Before I read your comments I tried downgrading through the S2 app but after resetting and finding my Playbar during the reset it just constantly said ‘your mobile device couldn't connect’ so I gave up

Any ideas why my mobile device couldn't connect because I obviously can't continue until this is resolved. 

Dumb question no1: Would connecting an ethernet cable between the PlayBar and my router help?

Thanks

Before it was possible again to downgrade i did try every possible way i could find and all the steps others did say, nothing did work. Also after the downgrade was possible again i did encounter problems. First step is downgrade the speakers that you want from the S2 to S1, reset them to factory settings. You really need to reset all speakers to factory settings or else you encounter problems that speakers wil not be seen in the app. And before you go en setup the speakers, uninstall the apps, both S2 and S1. And then download the S1 app only and one by one install the speakers. That was the way that i could get all speakers connected to the S1 app again. I really don’t understand why these are the steps and why Sonos themselves don’t know the steps, but they did work for me.  
Connecting to a ethernet cable is always better. It makes it easier to connect the speakers to the app. 

Thanks again.

I’ll give it a go again later and let you know how I get on.

Couple of questions though……….

I’m guessing you did the downgrade using your mobile phone, correct?

Where can you get the S1 app from? My mobile is a Samsung Galaxy Note 10 so wouldn't that only download the S2 app when reinstall? 

Many thanks

Paul

I did use my iPhone 12. You must use both S1 and S2 or else it will not work. 
but older model iPhone’s must work also, aslong you have both apps.
