Question about the CR100 and legacy mode

I don’t know what the absolute latest OS version for CR100 is, but the current S1 version OS most certainly does not support CR100s.

That’s what I thought. Thanks for the quick reply, I will stick with 8.4.

Yes 8.4 definitely the latest that supports CR100.

Given all things that couldn’t happen:

• impossible to have two versions of apps
• impossible to support legacy versions of code
• impossible to have different code bases on different devices

then it is highly likely that S1 could support CR100, despite protestations to the contrary. It’s not like s1 supports SMB or other major change. In fact other than Google voice I struggle to see what has been added since 8.4.

But it won’t happen. So we are stuck with 8.4 until such time as it is unworkable and then we will have to upgrade. Maybe by that time there will be a decent app or desktop version that can be used.

To be honest not having constant updates is a relief!

Quick question. Is anyone on 8.4 still able to cast from Spotify App direct to Sonos device, Mine stopped working a while back. I can cast from Spotify App to other things like Sky boxes. They do appear in list and attempt to send but then fail.

Can still use CR100 to locate tracks and play on Spotify. It is just the casting to devices that fails. Alexa has the same issue with casting. Not sure if it is a network issue or a functionality change in Spotify. Cheers

Is there any way to upgrade a ZP100 from software version 5.1 to version 8.4? The ZP100 is recognized by the PC controller, and I can add the ZP100 to my Sonos system that has six other players running 8.4. But the older ZP100 isn’t functional to play music and sync with the other players unless I run a software upgrade, which of course will be S1. But I don’t want that, I only want to upgrade to 8.4.

Is there any way to accomplish this? Perhaps make the older ZP100 get its update from the other players on my system running 8.4, and not upgrade via the internet?

I have a feeling there isn’t any way to do this, but just thought I would ask. Thanks for any thoughts and possible solutions.

No, not without an extraordinary amount of work, including the acquisition of an 8.4 image for the CR100 (the time to capture was, what, four years ago) and the creation of a fake Sonos update endpoint.

Thanks for the response. I was thinking of some type of fake endpoint as you suggest to trick the ZP100 into updating itself from a local network address that I control, and which has the 8.4 update software stored in it. 
 

Since Sonos and the preservation of my four CR100s are essentially a pet project for me at this point, I am not adverse to an extraordinary amount of work, as you put it. Would it be possible to create an image of the 8.4 update software, using one of my existing 8.4 hardware devices? The genie is in the bottle of those hardware devices, it seems to me. If I could get the necessary image, it would be a major step toward setting up the unique update system that you mention.

No. The time to capture the 8.4 image is when the device upgraded to it, ie years ago. Its a signed download, so you can’t re-create it from an existing device. It is remotely possible it is still sitting on a Sonos CDN somewhere, but I have no idea how to find something like that.

Thanks for your insight, much appreciated. If by some miracle I ever come up with a makeshift solution to the problem, I’ll post it here.

I’m also using 8.4 as I have two CR100’s as well. If anyone could come up with a way of installing 8.4 firmware on secondhand Sonos
