Connect Gen 1 - Update Problem

I bought a couple of Sonos bundles a long time ago. I had a Sonos Connect Gen 1 in storage that had never been setup, which I am now wanting to use.

I added it to my Sonos network, but the S1 app is now informing me that if needs a firmware update (of course). When I tell it to do the update it fails with a 'Error Code 803: Connect'.

It is definitely very out of date showing a version 3.8 compared to my other S1 device ls showing version 11.16.1.

From reading other posts, I believe I need Sonos Support to force/push a software/firmware update to it.

I have generated and submitted diagnostic report.

Moderator Edit - Recorded and removed the diagnostics number.

Sonos support have given me a URL string to connect directly to the device (locally) and I assume I can then manually trigger the incremental software/firmware updates until I’m up to a level where the standard update process will work.

One more interesting function in the :1400 area, only few known ones.

“future Sonos community searches”?

Have you actually tried the forum search feature? 🤣

(Un)fortunately the LostSight AI uses the Community search and (often) incorrect best answers to build its AI summary, GIGO. A hallucinating monster that eats its own excrement.

Edit: Delayed due to AI moderation, the irony! 🙄
