What Does Arlo Error 4101 Mean and How Do I Fix Firmware Update Failed?
- Internet connection dropped during firmware download from Arlo servers
- Camera battery too low to complete firmware installation
- Base station lost power during firmware write process
Problem Description
Your Arlo camera or base station shows Error 4101 which means a firmware update failed to install. The Arlo system attempted to download and apply a firmware update but the process was interrupted or the firmware file was corrupted. Error 4101 can leave your camera or base station in an unstable state where some features do not work correctly or the device repeatedly attempts and fails to update. This is one of the most commonly searched Arlo error codes because firmware updates are pushed automatically and users have no control over when they happen.
Symptoms
- Arlo app shows Error 4101 firmware update failed notification
- Camera or base station LED blinking amber indicating update in progress but never completing
- Camera features like motion detection or recording stopped working after failed update
- Arlo app shows firmware update available but tapping install always fails
- Base station shows solid amber light instead of normal green
- Camera disconnects from base station repeatedly after failed firmware update
Recognize these? Here's what usually causes it.
Common Causes
- Internet connection dropped during firmware download from Arlo servers
- Camera battery too low to complete firmware installation
- Base station lost power during firmware write process
- Arlo cloud servers experiencing issues serving firmware files
- Camera too far from base station for reliable firmware download via wireless
- Previous firmware version incompatible with the update requiring intermediate update first
Most fixes happen in the first 3 steps.
Never remove the battery from an Arlo camera while its LED is blinking amber indicating a firmware installation in progress. Interrupting the write process can corrupt the camera firmware and potentially brick the device requiring warranty replacement.

Step-by-Step Solution
Reboot the Base Station or SmartHub
Unplug the power cable from your Arlo base station or SmartHub. Wait 30 seconds. Plug it back in. Wait 2 to 3 minutes for the LED to turn solid green indicating it is fully online. The base station will automatically check for pending firmware updates for itself and connected cameras. If a camera firmware update is pending it will retry the download and installation. Monitor the Arlo app for update progress.

$8.09Check Camera Battery Level
In the Arlo app tap the camera showing error 4101 then tap Settings then Battery. If the battery is below 50 percent charge it fully before attempting the firmware update. Firmware installation is power-intensive and the camera will abort the update if the battery drops too low during installation to prevent bricking. Charge to 100 percent then bring the camera back online to trigger the update retry.
Move Camera Close to Base Station
Firmware updates are downloaded from the base station to the camera over the wireless connection. If the camera is far from the base station the transfer can be slow and unreliable causing 4101 errors. Temporarily move the camera within 10 feet of the base station with clear line of sight. Leave it there until the firmware update completes successfully. Then move it back to its permanent location.
Manually Trigger Firmware Update
In the Arlo app go to Settings then My Devices. Tap the affected camera or base station. Tap Device Info then Firmware. If an update is available tap Update Now. Keep the app open and on this screen during the update. Do not close the app, switch to another app, or let your phone go to sleep. The update typically takes 5 to 15 minutes depending on the device.
Factory Reset If Update Continuously Fails
If error 4101 persists after multiple retries the firmware may be in a corrupted state requiring a factory reset. For Arlo cameras press and hold the sync button on the camera for 15 seconds until the LED blinks amber then release. The camera will reset to factory defaults. For the base station press and hold the reset button on the back using a paperclip for 10 seconds. After reset re-add the device to your Arlo account through the app. The latest firmware will be installed during setup.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the device became unresponsive after a firmware update, a factory reset usually clears the corrupted state — the update itself is rarely the root cause.
Arlo pushes firmware updates automatically usually overnight. If you want to control when updates happen check the Arlo app periodically for pending updates and install them manually during a time when you have strong WiFi and fully charged camera batteries rather than letting them happen at random times.
Firmware updates that wipe settings are more common than brands admit — many devices silently reset to factory defaults on an OTA push with no warning.
