Not long after a recent firmware update, things started getting weird with my Google Nest Hub Max. It started getting slower, became unresponsive to commands, and worst of all - started rebooting intermittently.

Why does Google Nest Hub restart randomly?

Google Nest Hub keeps restarting because of system inconsistencies that may have arisen after a recent firmware update. Loose cable connections can also result in restart loops.

If your Google Nest Hub keeps restarting, check your cables for loose connections. If there are no signs of wear and tear, refresh your Google Nest Hub and check for updates. If none of the above works, factory reset your Nest Hub.

Read on to learn about the different troubleshooting steps that can fix your Google Nest Hub that keeps restarting.

Check the Nest Hub Cables

The absolute first thing to check and take care of in dire situations like a restart loop is the cable situation on your device.

Shoddy connections can lead to intermittent reboots due to slack power cable connections, which entails irregular power supply to the device.

Furthermore, slack power connections can lead to other harmful issues like internal short circuits. Over time, these short circuits can potentially cause a total system failure.

Best if you unplug the cable and plug it back. Ensure a snug fit even if the port exhibits resistance to your pressure.

If you have a tight enough connection and still the device shows signs of distress, better check the power supply port to which the power adapter is connected.

The best way to check and ensure optimal supply from the ports is with a multimeter (if you have one handy).

Connect the leads of the multimeter to the port and check the outcomes. If you see a deviation from the norm (120V in the US), better change the port and check again.

One other thing to note is the type of power adapter and cable.

If you're using third-party power supply solutions to power your Google Nest Hub, there is a high chance for issues to pop up on your device.

If that's the case, switch the power supply to the Google-supplied power supply and check for the issue now. Better to stay away from third-party accessories unless they are certified by Google.

Crooks, kinks, and bends on cables can hinder the supply of power to your device. Straighten the power cable at once you notice any such discrepancies.

Damaged hardware can lead to a whole host of issues on the software front, such as black screens of death.

Rusty cable ends are yet another sign for cable replacement. Keep a keen eye for any such corrosion on your cables.

Refresh Your Google Nest Hub

One plausible yet detrimental reason for restart loops on your Nest Hub may be erroneous bugs and errors that may have taken refuge in your device.

These glitches, if gone unnoticed, will cause problems on your device. Restart loops being one of them.

Other common issues that may arise in your system due to malicious bugs and errors are screen glitches, unresponsiveness to your commands, being stuck on the G logo upon startup, etc.

Ironically though, a quick fix to stop such latent bugs, and the issues caused by them, is to refresh your device.

And the best way to refresh your device in situations such as the one at hand is through a power cycle test.

A power cycle test, contrary to its formidable name, is simple. Here's how to do so:

Start the procedure by unplugging all the cables connected to your Google Nest Hub.
Leave the device idle for a couple of minutes.
Then, press and hold the volume button or the power button for a few seconds, say 5-10 secs. This step is an integral part of the fix since, in doing so, you will deplete any pent-up charges in the device. Repeat this step a couple of times.
Next, connect back the cables and check for the issue now.

You can also restart the Nest Hub through the Google Home app on your smart device. Follow these steps to do so.

1. In the app, click and open your Google Nest Hub device tab.

2. Tap on the Settings(gear) icon on the top right corner.

3. Then, click on the More icon(three vertical dots).

4. Select Reboot and confirm your selection by pressing OK.

Check for Updates On Your Nest Hub

Another great way to fend off bugs and other erroneous interlopers from your system is to keep it updated.

As crucial as it gets, updates ensure adequate protection against latent bugs, stale files, and other glitches that could possibly harm your device.

Google devs come out with potent fixes frequently through firmware updates and patches after scouring through forums and analyzing user claims of erroneous activities.

Never turn a blind eye to timely updates.

And if the updates prove to be the source of the problem, be on the lookout for yet another update that addresses any such bugs resulting from previous updates.

Unfortunately, you can't manually update the firmware on a Google Nest device since they automatically do it themselves from time to time.

You can, however, observe the progress or the circumstances of the update on your Google Nest Hub once the device starts updating.

To check whether your device is up to date or not, follow these steps on the Google Home app.

1. Open your Google Nest Hub device tab from the Home screen.

2. Tap on the Settings icon.

3. Scroll and locate the Firmware version tile.

4. Now, compare the mentioned firmware info to Google's most recent offering on the internet.

Once the Nest Hub completes a firmware update, usually, it tops off the update process by restarting itself.

On the off chance that Google comes out with multiple updates in a small time frame, your device will restart every time it completes an update.

Factory Reset the Google Nest Hub

If nothing seems to resolve the issue, as a final straw, try factory resetting the Nest Hub as a fix.

Factory resetting your Nest Hub will revert the device back to its factory settings, essentially stripping it clean of all the malicious bugs and errors.

A word of caution - hard resetting will also wipe your device's memory clean and reset all your personal preferences, including any prior routines, schedules, and whatnots.

The process is a bit time-consuming. Hence, best not to tinker around with the device while resetting.

You can reset your device in two ways- through the app interface or through the analog method.

Let's look at the analog method first:

Start by unplugging all the cables connected to the device.
Then, while pressing and holding the Volume down button, connect back the cables and power on the device. Doing so will cause the device to boot into recovery mode.
The message onscreen will prompt you to press and hold both volume buttons to initiate a factory reset.
Press and hold both the Volume buttons for about 10-12 seconds to begin the reset.
Once initiated, the voice assistant will inform you of the progress.

After the reset finishes, set up your Nest Hub from scratch.

The second method to reset your Nest Hub is through the interface commands on the Google Home app.

Here are the steps to reset your Hub remotely from the Google Home app.

1. Tap and open your Nest Hub device tab from the home screen.

2. Click and open the Setting icon from the top right half.

4. Tap on the More option(3 dot icon).

5. Select the Factory Reset option and confirm your selection.

Check for the issue once the process completes.

Final Thoughts

Apart from the fixes mentioned above, any issues with the Google Home app can also mess up the Nest Hub.

If that's the case, try uninstalling the Google Home app and reinstalling it again. Check for the issue now.

Also, there are known instances of recurring reboots as a result of hardware malfunctions.

If none of the fixes mentioned here seems to take effect, you might as well consider the chances of a hardware issue.

If so, better contact the customer services of Google for further assistance. Also, best if you don't take things into your own hands and aggravate the issue into something much more harmful.

Google does offer a free replacement for any malfunctioning devices if proven to be the case of a hardware malfunction.

Do try out all the fixes mentioned above before enlisting expert help.
