I tried pushing the latest firmware (1.0.5ww) to my M300 dashcam. Knowing that the power was not interrupted, the camera went down and it's not turning on! Please any suggestions?
You can try update from SD card.
Turn off camera. Remove SD card and copy FW_DR1300.bin on SD card root.
Insert SD card back ito the camera and turn it on.
Wait until update is finished. Button will be blinking for two or three minutes.
You can download file from HERE
There is also PDF manual how to install firmware.
I have received that file during testing of M300 dashCam.
