Thanks

Perhaps cable the Connect direct to your router with an Ethernet cable and then try the update again.

I should have mentioned that...it is hard wired to my router.

I would try the other network port on the device and/or another cable, as the error. by all accounts. is a communication error - or perhaps try the update over WiFi if you have your WiFi credentials installed in your Sonos Household.

I tried the other ethernet port and wifi.  Same problem.

I suspect that the flash chip is not writable for some reason.  Hopefully the Sonos team can see something in the diagnostic log.

I took the plunge, and hooked up a serial port monitor.  The flash has a bunch of bad blocks…

The skipped “.” lines include every intermediate block.  So there are 581 bad blocks out of 2048… no wonder it’s giving problems.

I recently acquired a flash programmer.  Maybe I’ll try to copy the existing flash contents to a new chip.

Hi @timc995 

It is indeed a bad block problem. I would encourage you to get in touch with our technical support team for replacement options, but it sounds like you have opened the unit in which case we cannot receive it.

Yes it’s opened up.  I wouldn’t expect any assistance from Sonos on a 7 year old device.

If this thread doesn’t get closed, I will report back on any results with respect to replacing the flash chip.

 

Time is the most frequent reason for closing a thread, not content, at least over the last several years. Sonos is pretty forgiving, as long as you stay within the community rules about posting. 

There are just a few threads here about opening up Sonos devices. I think there’s likely another, more welcoming place out there to get advice. For what I suspect are a multitude of reasons, Sonos doesn’t officially support the opening of their hardware.

We would have offered a 30% discount on a replacement, though your own solution will certainly be cheaper - if it works.
