Trying to downgrade Play:5 (Gen 2) to S1. Error

17 replies

I’ve been following the instructions to downgrade my Play:5 (Gen 2) to S1. I’ve factory reset it and waited for the flashing green light. However, the S2 downgrade process under support in the app always says “We can’t find a product to downgrade” with a Try Again button. I’ve tried maybe 12 times, nothing. I’ve tried wifi and ethernet, nothing.

When I search for it in the S1 app, it finds it but says it needs downgrading from the S2 app first.

Please could someone help?

There where valid reasons for the S1/S2 split. Why is this a surprise for you? Sonos does publicise this: https://support.sonos.com/s/article/5097?language=en_US

The One ís downgradable.

The One ís downgradable.

But the OneSL isn't.

I believe it runs fine in an S1 system but once upgraded/added to S2 it can't go back.

That's a bit poor if the One SL can run on S1 but not be downgraded if it is "upgraded" to S2..

Happy to be corrected on that - and also interested in the reason why it's the case (if indeed it is).

I have just purchased a couple of One SL's to add to my my existing S1 system. I currently have Connect's, Connect AMP's and a CR200 Controller. All S1 series devices only.

The S1 app sees the One SL and tells me it needs downgrading. I follow all the instructions, install the S2 app and go through the downgrade process... but alas it cannot discover it to downgrade.

Both the S1 and S2 app can discover it normally.

The retailer believed it could be downgraded and the online documentation appears to indicate it should.

The notes on this article imply that they are initially compatible with S1…

1 One SL can only be added to S2 systems. One SLs that are already part of an S1 system will continue to work as they do today.

But no success, so back to the retailer i go.

It looks like I'll have go upgrade from One SL's to straight One's with Alexa which I don't want/need.

Yes, once an old Sonos One-SL (pre-May 2021) has been allocated to an S2 system, there is no going back. They cannot be downgraded to S1. It’s also the case that any new purchased One-SL’s (post May 2021) are S2 compatible only.

i know this thread is a little bit old but this is what i did.

i purchased a play 5 gen 2 from offerup. i tried just resetting and downgrading but that didnt work.

i had to add it to my sonos s2 app, (it then did a firmware upgrade).
2. i did a reset s2 app
3. i did a reset of the play 5(holding down the sync button while plugging in).
4. opened up the s2 app and ran through the “other options” to do the downgrade and then it worked.

hope this helps the original poster if he still is having issues.
