If you fail to upgrade firmware via Reolink Client, there are several possible causes and solutions for you to check.

Applies to: All Reolink cameras except for battery-powered cameras.

Cause 1. The new firmware you've downloaded does not match your device

Solution: You need to know the model of your device and its hardware version. Then go to Firmware Center and find the correct firmware.

If you’re not sure about it, please share the system info page with the support team and we will help you identify it. Please refer to How to Find out System Information (Firmware Version) via Reolink Software.

Cause 2. Corrupted/Not supported file

Solution: All firmware is in .pak format. The file you downloaded from the Firmware Center is the .zip file, please unzip it and then you will get the .pak file. 


Cause 3. Network issue

Solution: It is suggested that you upgrade the firmware on LAN. That is to say, your PC where the Reolink Client is installed is on the same network as your camera or NVR.

Cause 4. The Reolink Client is not the latest version

Solution: Please check the Reolink Client version installed on your PC. Make sure you have installed the latest version released on our download center.

Cause 5. The current firmware of your device is way too old

Solution:  Please first upgrade the firmware to transitional firmware (newer than the device's current firmware but older than the latest one released on the download center), and then upgrade it to the latest one. If you do not have such transitional firmware, you can contact Reolink Support Team for help.
