15.1 Update not working on Sub Mini - Infinitely Updating and Blue Dot

Just to add the sub-mini has not been available long enough to not be under warranty and I’ve got two of them here at home that have each updated fine. I would always personally recommend updating the software as there maybe security updates included, aswell as fixes.

At least then you will know your setup is performing at its best. It’s more likely that ‘bugs’ will be removed rather than introduced… the issue reported here is not a widespread matter but seems isolated to a few cases only as I’m sure that this forum would have been bombarded with many hundreds of posts.

As it’s a new Sonos product I would definitely continue to do the updates otherwise you may end up with a sub-par system (pun intended). I think this was probably just a case of c’est la vie.

Just to advise that I have had the same issue with my Sub-Mini locking up and failing on the update at the beginning of March after only a few weeks of use. The Beam Gen2 next to it updated without a problem.

I went through everything with the technical team, including hard-wiring, factory reset, and full diagnostic check on my router, without response..

I now have no sub, as the unit is on its way back to the factory in Poland in the hope of replacement.

This appears to be indication of an issue with a manufacturing batch or the Sub-Mini hardware/firmware in general, and clearly from the above is not an isolated matter.

My sub mini is stuck ‘updating’ in the app now too, was the app required an update to set up the Era 100 and its borked my sub. 
 

Did anyone in this thread actually get theirs working again? Or are all these subs headed back to get repaired/replaced?

Worth also noting for anyone interested / stumbling across this thread—my sub has stopped working, and is stuck “updating”, after installing app version 15.2

I too have had the very same issues over time. First with a Port a few years ago with the only resolution being to have to buy a new one. 
Now, again, in the last few weeks, my 5, Sub, 2x1’s and Playbar all stopped working. 
After doing all the tests, resets, and various contortions we all now love so well, I’ve got the Playbar and 1x1’s working again. The rest …. nada. 
 

You would have thought that after years of this ‘update’ issue being a ‘thing’ that Sonos would know of a fix by now. It’s not like this is a new problem. 
 

I have a feeling that this will all end up with Sonos telling me the only fix is to upgrade or replace. 
What a surprise (not).

Literally just unboxed a brand new Mini Sub and can’t get any update to work.   If I have to call Support, send it back, etc. that is a MASSIVE QA issue that seems persistent.  I bought via Best Buy, so it isn’t inconceivable they have had stock on this Mini for months.   If there are this many issues with updates, they need to do a stock balance to get inventory updated.   I own way too many Sonos products, but this is one of the most disappointing unboxing experiences i have had.

While I don’t have a Sub mini, I’ve been updating products from Sonos for around 20 years, and only once needed to call in to get a special update build. It seems hard to believe there’s been enough time between when Sonos released the Sub mini and now for there to be that sort of issue. 

It sounds like there’s some other local network issue, and not a problem caused by Sonos. If you were to provide more details about your situation, it’s possible the community can help you correct the network issue causing you not to be able to update the mini. 

I appreciate the help, Bruce.  I have been escalated to Level 2 support with Sonos and have gone through two rounds of every type of hard reset, etc. guidance they have given.  It does seem like a network issue, except I can’t update my mobile iPhone app either.  It sees the device immediately but nothing will update.   All paths lead to the same error message:

Did you consider trying the update whilst the Sub-Mini is ‘temporarily’ wired to the LAN - obviously though you do need to get your controller device Sonos S2 App updated first of all, but that can be done simply via the iOS Apple App Store.

And if you’re experiencing difficulty when running the update from within the Sonos controller, I’d really be looking at some sort of software blocking. Things like VPNs, virus protection, work profiles on the phone, any port blocking or permissions app of some type. More likely to be at the router level, but I wouldn’t exclude the device your controller is on, I’m not sure whether updates get funneled through that or not.
