We have an older Sonos Play:1 speaker that I bought for my wife a few years ago, which she uses to play her music (MP3s converted from her CDs) from the SD Card of her Android phone. This has always been our only use for this device, with no interest in streaming services beyond occasional linear radio station listening.
We disabled Android app updates via the Play Store a couple of months ago in order to block Sonos's stated intent to deliberately break our purchased product by preventing local file playback, and this seemed to be working fine until fairly recently.
What I think has happened is the firmware in the speaker itself has somehow been updated, the result being that all of our phones are now insisting that we need to also update the apps before it will continue - which of course is the last thing we want to do!

I've Googled rolling Sonos firmware back, but most of the results are about doing a full factory reset in order to downgrade a S2 system to work with the S1 app, whereas we only want to roll back (and then lock) to the immediately preceding firmware build.
Could someone point me to how to reset the device, and then force an update to whatever specific firmware version would have been active in June (rather than the latest build)? Otherwise, this firmware update will have created a Sonos Brick as this expensive speaker is currently utterly useless to us. :(
