The upgrade steps need the firmware from Reolink Support Team, users should upgrade the firmware via the app normally.
Step 1. Insert the micro SD card in the micro SD card reader and plug it to the computer, copy the upgrading file to it, please just copy the file to the root folder rather than any subfolder. The file name is tar.gzwhich CANNOT be modified.
Step 2. Put the micro SD card to the camera, then insert the battery to power it on, when the red LED is on, please use a toothpick or something sharp to hold the reset button (shown in Figure 2) for about 2 seconds.
The red LED will go off, please release the reset button. The camera will restart, the red LED will flash quickly 3 times and the device will restore to factory default settings. If an upgrading file is detected in the SD card, the camera will enter upgrading mode.
Step 3. When it starts to upgrade, the LED light will flash both red and blue, which will last for 1-2 minutes. Please do not cut the power during the upgrading process.
When the red and blue light goes solid, it means the camera is upgraded successfully, please take out the battery to restart the camera.
But if the red and blue light will not go solid after 5 minutes, it means upgrading has failed, please try again.
Step 4. After successfully upgrading the firmware, please take the SD card out and delete the upgrading file, or format the SD card via the camera, in case of the camera will enter the upgrading mode again when it’s reset to factory default.
