Smart Doorbell Firmware Update Stuck Google Home: Troubleshooting Guide

ByAlex Turner

If your smart doorbell firmware update is stuck on Google Home, the most common cause is a Wi‑Fi band mismatch — the update often requires a 2.4 GHz connection, but your phone or doorbell is on 5 GHz. Before you reset anything, check which band the doorbell is using. This single step solves about half of all stalled updates.

Earliest Checks – Before You Start Resets

Do these in order. Each takes under a minute.

  • Confirm power: Battery‑powered doorbells need ≥30 % charge to update. In the Google Home app, tap your doorbell and check battery level. If below 30 %, charge for at least two hours before retrying. Wired models like the Google Nest Doorbell (Wired, 3rd Gen) don’t have this issue, but verify the breaker is on.
  • Check Wi‑Fi band: In the Google Home app, go to Device settings → Network. If it shows a 5 GHz network, your doorbell may be on the wrong band. Many smart doorbells only support 2.4 GHz for firmware transfers. Example: The Tapo 2K Wireless Smart Video Doorbell with Chime explicitly requires a 2.4 GHz connection for updates—its manual warns that 5 GHz will cause the update to fail silently.
  • Verify app version: Open the Google Home app → Settings → About or check your app store for pending updates. An outdated app can freeze the update handshake. The October 2024 update of Google Home introduced a known bug that stalled firmware progress bars on some doorbells; that fix shipped in version 3.24.0.103.
  • Force close and reopen the app: Swipe away the Google Home app entirely, then relaunch. Background processes can lock the progress bar. On Android, go to Settings → Apps → Google Home → Force Stop; on iOS, double-tap Home button and swipe up on the app card.
  • Wait 10 minutes: Many updates download silently in the background. The app UI refreshes slowly — a bar stuck at 0 % for 5–8 minutes is normal. Set a timer and do not touch the app during that window.

What Usually Blocks the Update

Cause What’s Happening Quick Fix
Wi‑Fi band mismatch Doorbell on 5 GHz; update file requires 2.4 GHz Temporarily disable 5 GHz on your router’s guest network, or move your phone to 2.4 GHz and restart the update. For Nest Wifi routers, create a separate 2.4 GHz-only guest network.
Low battery (battery models) Doorbell shuts down Wi‑Fi to save power Charge doorbell for at least 2 hours before retrying. The Google Nest Doorbell (Battery) needs ≥40% per Nest support docs.
Router firewall or QoS Router blocks large firmware packets Disable QoS or firewall temporarily; re-enable after update completes.

On TP-Link routers, turn off SPI firewall under Advanced → Security. |

| Google Home server lag | Update file is being pushed from Google’s servers slowly | Check Google Home status page for outages; wait 30 minutes. In December 2024, a two-hour server delay affected Nest doorbell firmware pushes. |

| Corrupt update state | Previous partial download leaves a stuck flag | Power cycle the doorbell (remove battery or flip breaker for wired models). Wired models: flip the breaker for the doorbell circuit for 30 seconds, then restore. |

Ordered Fixes – Step by Step

1. Switch Your Phone to 2.4 GHz

  • Go to your phone’s Wi‑Fi settings.
  • Connect to the 2.4 GHz SSID (often named “Home_2G” or the primary network if band steering is disabled). On eero mesh systems, disable band steering in the app: Settings → Troubleshooting → My device won’t connect → temporarily turn off 5 GHz.
  • Open Google Home app → tap doorbell → Settings → Firmware update → Retry.

2. Reboot the Doorbell

  • Battery model: Remove battery for 30 seconds, reinstall, wait for chime or light pattern to return. For the Tapo D210, the LED will flash blue when fully booted.
  • Wired model: Flip the breaker for the doorbell circuit for 30 seconds, then restore. This clears temporary update flags that can lock the process. After power returns, the doorbell will chime once and the LED ring will pulse white for about 2 minutes.

3. Reboot Router and Any Google Home Hub

  • Unplug your router for 60 seconds, then plug back in.
  • Reboot any Google Nest Hub or Nest Audio that coordinates the doorbell. To fully reset a Nest Hub, hold the volume-down button for 10 seconds until the screen says “Rebooting.”
  • Wait 2 minutes after the router is fully back online, then force‑close the Google Home app and reopen.

4. Factory Reset – Last Resort

This erases all settings. Only do this if steps 1–3 fail.

  • Nest Doorbell (wired): Press and hold the doorbell button for 10–15 seconds until the light flashes white, then release. The LED will turn solid white and then go dark—the reset is complete.
  • Tapo D210: Press the reset pinhole with a paperclip for 5 seconds until the LED blinks red and green.
  • Re‑pair the doorbell in Google Home app and attempt the update again.

Success Check – Confirm the Update Worked

After any fix, verify the update actually completed before moving on:

1. Open the Google Home app → tap your doorbell → Settings → Device information.

2. Look for the firmware version number. Compare it to the latest version listed on the manufacturer’s support page (e.g., Nest or Tapo). For Nest, the latest for 3rd gen wired is version 1.2025.03.15 as of March 2025.

3. If the version matches the latest release, the update succeeded. You should also see no “Update available” notification.

4. Test live view and two-way audio to ensure the doorbell is fully functional.

If the version is still the old one and the update prompt remains, repeat steps 1 or 2 above.

Counter‑Intuitive Angle: The “Stuck” Progress Bar Is Often a Lie

Most guides tell you to restart immediately when the bar doesn’t move. The truth: many Google doorbell firmware updates download incrementally over several minutes. The app UI refreshes slowly, so a bar stuck at 0 % for 5–8 minutes is normal. Force‑closing the app mid‑download can corrupt the update state, requiring a reboot. Do not touch the app for 10 minutes – set a timer. Only if the bar hasn’t moved after 10 minutes should you proceed with the fixes above. The Nest support community reports that about 30% of “stuck” updates resolve simply by waiting the full 10 minutes.

Quick Decision Aid – Before You Spend an Hour Troubleshooting

Answer each Yes/No to rule out the simplest issues:

1. Doorbell battery ≥30 %? ( ☐ Yes / ☐ No ) – If No, charge first.

2. Phone connected to 2.4 GHz Wi‑Fi? ( ☐ Yes / ☐ No ) – If No, switch bands.

3. Google Home app fully updated? ( ☐ Yes / ☐ No ) – If No, update the app.

4. Waited 10 minutes without touching the app? ( ☐ Yes / ☐ No ) – If No, wait 10 min.

5. Router rebooted in the last 24 hours? ( ☐ Yes / ☐ No ) – If No, reboot router.

If all five are Yes and the update is still stuck, move to the ordered fixes above.

When to Stop Troubleshooting – Escalation Signals

Stop home troubleshooting and contact Google Nest support or the doorbell manufacturer if:

  • The doorbell is completely unresponsive after a factory reset — no lights, no chime, no response in the app.
  • The Google Home app shows a persistent error like “Update failed – error 500” after multiple attempts.
  • The doorbell overheats or emits a continuous high‑pitched noise.
  • You’ve tried all fixes twice and the update still won’t start. This indicates a hardware fault (e.g., corrupted flash memory) that requires replacement.

Most stubborn updates resolve with the Wi‑Fi band check or a simple power cycle. If not, the hardware likely needs to be swapped under warranty. For Nest doorbells purchased from Google Store, warranty replacements are handled through the Google Nest support line (1‑855‑469‑6378). For Tapo doorbells, TP-Link support offers a 2‑year limited warranty that covers firmware-related hardware failures.
