Downgrade Symfonisk Bookshelf gen1 to S1

I’m having this issue, too. Why doesn’t a factory reset remove the S2 software from the speaker? 
 

is there any way to move a Symfonisk v1 speaker from an S2 to an S1 system?

 Thanks, Mark

Thanks for the quick reply, Ralf. 

This is really ridiculous and disappointing when I’ve invested in more than 20 Sonos speakers. I’m running an S2 system at my home and an S1 system with some of my older Play:5 speakers at my cabin, and because I bought some ERA 300s for my home now I’m just wanting to move some older Symfonisk V1 speakers  to the cabin’s S1 system. It’s crazy that I can’t do that…

Thanks, Mark

Of course it is… and though we don’t know exactly how long it will take that update to be released it’s definitely announced to come back. So let‘s try to look at this from the only positive point of view. 😉

I call *.  I lost 5 subs due to this issue.  Fix it sonos. and fix it now!!!!

I have over 100K in sonos products and this new app and updates are causing me grief I have never experienced before.  Not impressed.  If you are going to brick s1 then let's just do it.  

How exactly could you “lose” 5 subs due to the inability to revert to S1?

for some reason they auto upgrade to s2 without my permission.  I know what I am doing.  

I run two systems dues to s1.  I am not prepared to replace 10 ZP100 that are still working.  The subs were working with them and not they are not after some unknown update.  I need to downgrade 5 subs and I will be happy.

Even it‘s not possible to update them to S2 without your decision to have updates enabled, I suggest to call Sonos support team. Maybe in the meantime until S1 downgrade is available again via app they can help you in another way.
