I have an old Sonos play 5, not used for a couple of years. Lady time it worked with a 3.5mm cake plugged in.
Now it asked to update the software, and I tried after a factory reset, with an Ethernet cable plugged in.
Sonos mobile app can see the device and suggests I update it. I try to, but it says Error 1002. Light flashes green green when power restored.
Help!
