Google Nest Community

https://support.google.com/googlenest/gethelp?hl=enPersonally, I got confirmed hardware change after chat with support team (choose "Google Home" as product family).

I second Hodge's recommendation about contacting Google support.Got also a confirmation from support about replacing my 1 year old Nest Hub 1st Gen (not bought in Google store).

Same here, my Nest Hub got stuck in grey "G". No suggesteted tipps about recovery mode helps 
