Phantom I Silver Update: Speaker Won't Restart, Any Solutions?

[scotthar]

Circa that is circa what model year?  are both of your speakers from the same batch/timeframe?

I saw something very similar in about 2018 or 19, my phantom I (white) circa 'H' model season stopped responding after the reboot during the first reboot of the firmware update.   (for some reason i recall there used to be multiple stages or reboots on the update)
Symptoms: no heat and no network activity
Solution was to replace it with a different unit. Devialet did the right thing in my case. 


btw - don't think you need to worry about the speakers overheating - though i DO turn my H models (that run much hotter than the newer L > hardware's) off when not being used to conserve power because they are like little heaters
