Besides online upgrading, Reolink 4G cameras (with smart detection) can also support manual upgrading. Below are the detailed steps for your reference.
Applies to: Reolink Go Plus, Go Ultra, Go PT Plus, Go PT Ultra, Go Ranger PT, Keen Ranger PT, Duo 4G, Duo 2 LTE, TrackMix LTE, TrackMix LTE Plus.
Step 1. Copy the firmware file to an SD card.
Insert the micro SD card in the micro SD card reader (Make sure that your SD card is 16GB or 32 GB in FAT 32 format) and plug it into the computer. Please create a folder named upgrade, then put the firmware into this folder.
Step 2. Insert the SD card into the camera and hold the reset button.
Put the micro SD card into the camera, then insert the battery to power it on. When the red LED is on, use a reset needle or something sharp (like a toothpick) to hold the reset button 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 the upgrading mode.
Step 3. Light will flash both red and blue, then go solid.
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, then 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.
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.
