ZP100 not booting

Hi,

I've recently acquired a ZP100 however it looks to be stuck in the boot process with a single white light flashing endlessly.

It doesn't appear responsive to holding the mute button on bootup. On powerup all of the network port light flash briefly and the connection lights are solid if wired to bridge via ethernet.

I know this is an old product and I know it is my fault for purchasing it, but is there any other reset tricks or way to update the firmware to get out of this loop?

So no joy. Not sure if I just got lucky with the cold spray or what, but my failure mode if back.
Going to try to swap out the ram chips and see what happens.

Been thinking after reading all of these pages of info. And my thoughts always lead to, what is the root cause of these boot problems? Some seem to be able to reinstall firmware and it fixes it.
Is there a smoking gun in all of this?

So - I had the same issue white light flashing couldn’t connect and no IP address being taken (Wireshark showing zilch)

Years ago I used to fix car radios by putting them in the freezer for 2 days. Apparently clears the electronics.

So I thought what the heck I’ll try - so I put the ZP100 in the freezer for 2 days. Took it out tonight, powered it up (careful with the ice) and hey presto I can reset and it’s now connecting.

Fingers X’d it still works when fully thawed but it is working...

I know it sounds odd but this did work for me..

So worked fine over night to this morning, I needed to put the cover back on so unpowered and repowered to see if it would keep its settings and it has reverted back to the flashing white light again....

HI. Where to download latest firmware for zp100(play5) and a100(sub) ?

From your Sonos Controller, look under settings and Check for Updates.

Hi, I am aware of that option. The issue is that it is bricked.

Then I'd recommend a call to Sonos to discuss it.

If it's bricked, a download of firmware wouldn't make any difference, you wouldn't be able to load it. And Sonos doesn't post downloadable versions of their software as packages, they only have the online update option.

Look through this thread for links. You should be able to download firmware from somewhere to your computer and then host on webserver and use UART cable to connect to sonos and then Update the firmware. But do not know where to get latent firmware. Good luck.
