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.

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.
