I recently got given my father in law's old Google nest mini. I am trying to set it up, but all it does is flash between no dots, two dots and four dots. After a while it stays on four dots then starts again. It never makes any sound and when I try to connect to Google home it cannot find the device. I tried to do a factory reset, but it doesn't seem to have any effect, it just turns on a green light while I hold the button and the light turns off when I let go. It is otherwise unresponsive. Please help! 😞
