they still sounded amazing until the S1 was bricked on my devices.

How did the S1 app “brick” your devices? All of the older Sonos devices are supported on the S1 app.

 I have a Play 5 and a Connect that I still use with the S1 app in my home with no issues.

The Play 1 and Play 5 Gen 2 are supported on the S2 app, so I do not get your post.

My Play 1 is still working like a champ on the S2 app.

My 2 x Play 1 works perfectly.. Have used them as surround with my Playbar.
I have now bought Arc Ultra and therefore sold them as I have chosen to upgrade my entire system with Era300 among others.

A moderator has already had to correct your disinformation on this thread

So why are you repeating it here?

Also, your post is randomly tagged “Sonos One”” despite your profile  (created last week) mentioning lots of speakers, but no Sonos One.  This looks like very sloppy trolling.

I have the Sonos App I just downloaded.  And trying to set up my Play 1s (I have 2 of them).  I’m trying to change the network connection from tethered Ethernet to Wifi.  It’s looking for unit that is plugged in and can only find a sound bar looking unit/ equipment.  Why the heck does Sonos not just make it default to WiFi after set up?  And why is the wifi or Ethernet option so imbedded in the system’s setting?  Should just be able to click on the speaker on the app and toggle from Wifi to Ethernet.  Who the heck is designing the software… user interface sucks!  Not intuitive.   For now I have one speaker tethered to my router.  Sonos is supposed to be wireless?  Ain’t that the big ploy?  Mission?  
 I’m 2 hours into setting up these old Sonos Play 1s.  And still not the perfect outcome.  Have factory reset it 3x… of which, why does it take over a minute of holding Dow the power button to factory reset?  I miss the days of the pin hole and you just pin to reset.

I have a similar issue. I have a Gen 1 Play 1, Gen 1 Play 5 and a Playbase. They all worked fine. I have recently moved house and they have been powered off for almost a year. I am now trying to set them up again from scratch and have factory reset them all. Every time I open the Gen 1 Sonos app, it states it wants to update when I try to add a device. It will not allow me to proceed without updating to the latest Sonos app version. As soon as I install it (IOS version), that version tells me it is incompatible with my older devices! So I am completely going round in circles. I installed the PC app, but everything is greyed out. I have sung Sonos praises in the past, often quoting their ease of set up with other inferior products (such as GoPro etc), but this seems to have taken a nose dive. Why release software that seemingly renders older products in to land fill?

Hi. Are you using the S1 app?

Btw there was no need to set  up from scratch. 

Some of the speakers you have will only work with the S1 app, so I suggest you delete the new app (Black) and only use the grey sonos S1 app. If you already updated the app, take a Play 1 or Play 5 near your router and connect it to your router with a cable. They may need to be hardwired to your router in order to be updated if they were powered off for a year.
