I have several Play 1, PLAYBASE and a Boost and a friend gave me an old ZP100 as I wanted to connect my garden speakers to my Sonos system. However, I have connected and factory reset and I can't update the firmware. Once I remove the ZP100 from the system it all works perfectly as before, when I do connect it start the update process but won't complete it. I suspect the version it is on may be to old to communicate with my controller, any ideas would be great as I am not in a position to go and buy a new Amp yet.
Thanks in advance.

You'll need to contact Sonos Support to discuss it. I suggest the phone folks, they have more tools available because they're on the phone with you, but they are only available Monday through Friday during business hours. Both the Twitter and Facebook support folks are available 24/7.
They'll probably need to create a special update sequence to push to your device, in order to get it properly updated.
