Why Does My Google Nest Hub Keep Restarting and Showing Google Logo

Problem Description

Your Google Nest Hub is stuck in a boot loop — it repeatedly shows the Google logo, partially loads the home screen, then restarts again. The device is completely unusable. Boot loops are caused by power delivery issues, a failed firmware update that cannot complete, or overheating. In most cases a factory reset using the hardware buttons resolves it without service.

Symptoms

• Shows Google logo then restarts endlessly
• Briefly shows home screen before rebooting
• Cannot interact with device during boot loop
• Hey Google voice commands do not work
• Screen flashes then goes to Google logo again
• Started after a software update

Recognize these? Here's what usually causes it.

Common Causes

• Failed software update corrupted firmware
• Power adapter not providing enough current
• Overheating causing thermal protection restart
• WiFi connection failing during boot causing retry
• Corrupted cache from full storage
• Hardware failure in older units

Tools & Requirements

Step-by-Step Solution

1

Full Power Drain and Cold Boot

Unplug the Nest Hub completely and leave it unplugged for 2 full minutes — not just 30 seconds. This ensures capacitors fully discharge and the device starts from a completely cold state. After 2 minutes plug back in and do not touch it for at least 5 minutes while it boots. A brief power interruption during normal operation can corrupt the running OS state, and a full drain clears it.

2

Factory Reset Using Hardware Buttons

Unplug the Nest Hub. Press and hold both the Volume Up and Volume Down buttons simultaneously. While holding both buttons, plug the power cable back in. Continue holding both buttons for 10 seconds until you see a factory reset screen appear. Select Reset. This bypasses software entirely, allowing reset even when the device cannot complete a boot cycle. You will lose all settings and need to reconfigure.

3

Verify Power Supply and Cable Integrity

Use only the original Google power adapter and cable that came with the Nest Hub. Third-party adapters that do not provide the correct voltage or amperage cause unstable boot behavior. Inspect the cable for kinks near the connector. Try a different wall outlet on a different circuit. A failing adapter may provide enough power to start the boot but not enough to complete it, causing a repeating restart cycle.

4

Allow for Thermal Cooldown

Press the back of the Nest Hub chassis. If it is uncomfortably hot, thermal protection may be triggering restarts before the boot completes. Unplug the device and let it sit in open air for 30 minutes. When you plug it back in, place it on a hard flat surface with the rear vents unobstructed. Do not put it on fabric, inside a cabinet, or against a wall that blocks rear ventilation.

5

Move Close to Router to Complete Pending Updates

If the Nest Hub has a pending firmware update it cannot download due to poor WiFi signal, it may repeatedly restart trying to apply the update. Move the device within 10 feet of your router temporarily. If it boots successfully at close range and downloads an update, the boot loop was caused by a failed update cycle. After the update completes you can return it to its original location.
