I was trying to update the firmware on my well used but working fine 2 yr old VIOFO A119 (capacitor) from 2.2 to 4.0. I may have done it incorrectly but now it wont turn on. I only get the glowing red <REC button but nothing else. Tried reflashing the firmware but nothing happens when power is connected. The OFF button will turn off the red button and back on but that's all I get. Need some super hard reset method to get it to start reading the SD card again. I tried the reset button too. Any ideas?
