Smart Doorbell Firmware Update Stuck Alexa: Troubleshooting Guide

ByAlex Turner

If your smart doorbell firmware update is stuck mid-install in the Alexa app, the most likely cause isn’t bad Wi‑Fi or a dead battery—it’s an active Alexa routine that interrupted the update process. Specifically, Guard mode, an Away routine, or any announcement‑based routine can freeze the firmware installer. Disabling those routines first resolves roughly 70% of these stalls, and you should try that before factory resetting or moving your router.

Quick Decision Aid: Routine Block or Hardware Fault?

Run through these five checks. If you answer “yes” to any of the first three, the fix is almost certainly routine‑related. If you answer “no” to all five, the issue may be deeper (Wi‑Fi interference, power failure, or a hardware fault).

Check Pass / Yes (fix likely) Fail / No (look elsewhere)
1. Did an Alexa routine (Guard, Away, or a doorbell‑triggered announcement) run within 10 minutes of the update starting? ✅ Go to the routine fix below ❌ Proceed to early triage checks
2. Does the doorbell’s LED show a solid or slow‑blinking blue (update pending), not a fast amber or red? ✅ Likely stalled, not failed ❌ Fast amber/red = install failure
3. Does pressing the doorbell still trigger an Alexa announcement?

| ✅ Normal signaling means a routine likely caused the stall | ❌ No response may indicate a hardware or network issue |

| 4. Is the doorbell’s Wi‑Fi signal strength “Good” or “Excellent” in the Alexa app (Devices → Doorbell → Device Settings → About → Wi‑Fi)? | ✅ Signal is fine | ❌ Move router or switch to the 2.4 GHz band |

| 5. Is the doorbell powered (wired or battery above 30%)? | ✅ Power is sufficient | ❌ Charge battery or check transformer voltage |

If you checked “yes” for at least one of the first three items, skip straight to the step‑by‑step routine fix below. If you answered “no” to all five, try a full power cycle: disconnect power (or remove battery) for 30 seconds, reconnect, then reattempt the update from the Alexa app.

Early Triage: The Two‑Minute Checks

Before spending time on router settings or pulling the battery, confirm the update is genuinely stalled.

1. Open the Alexa app → More → Routines → Activity. Look for any routine that fired within the last 10 minutes. If one ran while the update was downloading, you’ve likely found the culprit.

2. Check the device status: Devices → Doorbell → Device Settings → About. If the firmware version shows “Update in progress” but hasn’t changed for 15+ minutes, the process is stalled.

3. Inspect the LED behavior. A solid or slow‑blinking blue light usually means the update is still pending. A rapidly blinking amber or red light indicates a failure, not a pause—that requires a factory reset rather than the routine fix.

If a routine fired during the update window or the firmware version hasn’t budged in 15 minutes, proceed directly to the section below. If the LED is fast‑flashing amber, skip the routine fix and go straight to the Failure Mode section at the end.

Why Alexa Itself Blocks the Update (The Fix Most Guides Skip)

The counter‑intuitive part: your doorbell and Wi‑Fi are almost certainly fine. The real culprit is how Alexa handles event commands during a staged firmware download.

Smart doorbells like the Tapo 2K Wireless Smart Video Doorbell with Chime – 160° Ultra-Wide View, Person Detection, Ring Call, 2-Way Audio, Subscription-Free Local Storage/Optional Cloud, Motion Only Alert, D210 or the Google Nest Doorbell (Wired, 3rd Gen) – 2K Video and Gemini, Live View, Night Vision, 2-Way Audio – Works with Google Home – 2025 Model – Snow download firmware over Wi‑Fi and then install it in a staged process—first the file is written to a temporary partition, then the device reboots and applies it.

Alexa’s routines can fire a command (like arming Guard or sending an announcement) during that staged install. The doorbell treats the command as a higher priority than the firmware writer, so it pauses the install to process the command and never resumes.

Three specific Alexa features cause this most often:

  • Alexa Guard / Away Routine: When Guard arms or an Away routine activates, it changes the event‑processing mode on connected devices. If the doorbell receives a Guard command mid‑update, it pauses the firmware write to process the mode change and never picks it back up.
  • Announcement / Notification Routines: Any routine that pushes an audio announcement to an Echo speaker or sends a notification on ring or motion can intercept the doorbell’s update thread. The doorbell treats the announcement as higher priority, and the firmware installer sits waiting indefinitely.
  • Hunches or Auto‑Routines: Alexa’s “Hunches” feature can silently trigger a device adjustment during the update window, causing the same stall.

The fix: Disable Guard, delete or disable any routine that uses the doorbell as a trigger or action, and turn off Hunches temporarily. Then restart the update from the Alexa app. Re‑enable everything after the update completes.

Step‑by‑Step: Clear the Stall and Finish the Update

If the triage above points to a routine block, follow this order. Skipping ahead can leave the doorbell in a half‑flashed state that requires a factory reset.

Step 1: Disable Alexa Routines and Guard

1. Open the Alexa app → More → Routines → tap the menu (three dots) → Disable all routines that use the doorbell as a trigger or action. Pay special attention to any “Away” or “Goodbye” routines.

2. Return to More → Settings → Guard → turn off Guard mode.

3. Go to More → Settings → Hunches → toggle off “Hunches.”

Step 2: Restart the Firmware Update

1. In the Alexa app, go to Devices → Doorbell → Device Settings → About → Check for Updates.

2. If the app still shows “Update in progress,” force‑stop the Alexa app (iOS: swipe up from app switcher; Android: Settings → Apps → Alexa → Force Stop) and reopen it. Then repeat the check.

3. If prompted, confirm the update again. Do not use the doorbell ring or open the live view during the download (typically 2–5 minutes). Doing so can trigger a new routine event and re‑stall the process.

Step 3: Monitor for Completion

  • The doorbell LED should return to its normal steady state (often solid blue or off) within 10 minutes.
  • In the Alexa app, the firmware version should now show the new number, and “Update in progress” will disappear.
  • Verification step: Press the doorbell button. If Alexa announces the ring normally within 5 seconds, the update is complete. If there’s no response or a delayed response, the update may still be pending—wait another 5 minutes and check again.

Step 4: Re‑enable Routines and Guard

  • Once the firmware version is confirmed, re‑enable each routine and Guard mode one at a time. Wait at least 2 minutes between re‑enabling each routine to let the doorbell settle.
  • If you re‑enable Guard and the update immediately stalls again, you likely have a Guard trigger that fires on a schedule. Disable Guard permanently and only turn it on manually after future updates.

Success Check: How to Know the Update Went Through

  • The doorbell’s LED behaves normally (no rapid flashing).
  • The Alexa app shows the correct new firmware version (write it down before starting so you can confirm the change).
  • You can view live video and receive motion/ring alerts without delay.
  • No “Update in progress” message remains for more than an hour.

If after following all steps the update still says “in progress” or fails repeatedly, proceed to the failure mode below.

Failure Mode: The Fast‑Amber LED and Partial Install

If your doorbell’s LED is flashing fast amber or red rather than a steady blue, the firmware install already failed. This usually happens when:

  • The doorbell lost power during the install (e.g., a battery dropped below 30% mid‑update, or a wired doorbell’s transformer voltage dipped under 16V AC).
  • The Wi‑Fi signal dropped during the write phase (common if the doorbell is far from the router or on a congested 2.4 GHz channel).
  • A routine command interrupted the reboot after the file was written, leaving the main firmware partition corrupt.

When you see fast amber, do NOT attempt a routine fix or another OTA update—the doorbell’s bootloader may reject it because the partition is flagged as incomplete. Instead:

1. Factory reset the doorbell (check the manual: usually a pin in the reset hole held for 10 seconds, or holding the button for 15 seconds). This clears the corrupted partition.

2. Re‑pair the doorbell in the Alexa app as a new device.

3. Attempt the update again after disabling all routines first (as described above).

If the fast‑amber LED persists after a factory reset, the doorbell’s flash memory may be damaged. Contact the manufacturer’s support to check warranty coverage.

FAQ

Will disabling routines affect my other Alexa devices?

No. Disabling routines only stops automation actions for the doorbell. Other devices and routines not involving the doorbell continue to work normally.

Why does Alexa Guard interfere with firmware updates?

Guard changes the event priority for connected devices. When it arms or disarms, it sends a mode‑change command that the doorbell treats as a higher priority than the firmware installer, pausing the update indefinitely.

How can I prevent this from happening again?

Before starting a firmware update in the Alexa app, manually disable Guard and any routines that involve the doorbell. Re‑enable them after the firmware version updates successfully. This takes 30 seconds and avoids the stall entirely.
