If you have a Google Nest Hub, you can probably be lucky if you haven’t received an update yet. However, if you have received one and your Nest Hub is on strike for this one, then know that you are not alone.
Numerous users of a Google Nest Hub have found that it is in a reboot loop after the update – which is of course very annoying. The Google forum recommends the usual reboot, including disconnecting from the power supply, because everyone knows that “a boot is good for you”. That probably worked for some, but there are also users who had to reset the device:
Put the device into recovery mode (unplug the device and hold the volume up and down buttons while plugging the device back in. Release the volume button as soon as the device turns back on). Try to factory reset the device once it enters recovery mode (long-press the volume up and volume down buttons at the same time).
