I got a replacement for the bricked one. Fingers crossed it won't happen
again. Also bought a second one and one for a family member. Fingers

problem is?

item. That should be the case with mine (less than a year
old)!https://www.googlenestcommunity.com/t5/Chromecast/Chromecast-with-Google-TV-4k-bricked-after-the-update-during-initial...
