I have had no issues with the SanDisk High Endurance cards. In fact, I feel they have been one of the most reliable cards over the last few years, especially in Viofo cameras. I'm referring to their High Endurance cards only.
Format the card with SDFormatter. Perform the full overwrite, not the quick format. Format in the camera after SDFormatter.
After you updated the firmware, be sure to manually default the cameras settings in the menu, then press and hold the hard reset button on the side of the camera for about 5 seconds.
