I have done all the rebooting / factory reset steps. I have tried to unplug the Hub and wait 10 seconds and plug back in up to 11 times. I have turned off all my internet and done all the steps above with the internet off. I removed the device from my Home app. The Nest Hub will still only go to the recovery screen after the grey screen with the white G.
If the steps above do not help, please perform the steps below:
Place the device in Recovery Mode (unplug the device then hold down (long press) the volume button while plugging the device back in. Release the volume button once the device turns back on.)
Attempt a factory reset once device boots into Recovery Mode (hold down (long press) both volume up and volume down buttons at the same time.)
Again I removed the device from my Home app so I cannot reconnect it to send the feedback.
Sorry for the late reply. I wanted to follow up and see if you are still in need of any help with your device being stuck? I know this is not ideal. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
