I've been on the forum a couple of times. A couple years ago to figure out whether I could find an old speaker at retail that was still at v4.2 (so I could add a speaker)…a quest that was not successful (oldest I found was v4.3), although establishing that the approach might have worked. And last year checking into whether any of the changes made by v5.0 had been mitigated, in case something I was running 4.2 on died (answer then was "no").
So my 5 year old phone, which I use as my primary controller, finally needed to be replaced. I thought I would check in on any improvements…and it appears that SONOS has continued to work against the interests of someone primarily using a music server, listening to classical music, etc. (See my old threads for my details, the forum is well documented with the specific issues as well) as well as new issues. So I will continue to try to protect my investment by sticking with 4.2. And for now, my old cellphone can still act as a primary controller…so I have that going for me!
My question is…is there a way to port a version of v4.2 onto my new phone to buy me potentially additional time? I can see a couple paths: 1) copying a file from the old phone to new phone, or 2) downloading from a site like APKMirror (which unfortunately specifically doesn't go back earlier than v5.2 as far as I know). In theory download, get the router off the internet, set up and activate, then get the router back onto the internet. Is a workaround of this sort possible? Details? Risks?
(BTW 4.2 works perfectly for me, I would be happy sticking with it for years. Not interested in an update and have no interest engaging that discussion.)
