I have a Hero 4 Black adn used it well with a SanDisk SDSDQXP 64BG card. But yesterday, it starting giving me some SD ERR on screen an in my LG G3 Capture app.
It gave me an error after a 27 second recording at 1440 / 50. Also after a 11 second recording with the same video...
While updating firmware & software for new GoPro 3+, I loaded the update files onto the GoPro Micro SD Card.
I see that if we choose to DELETE ALL Videos/Photos on the menu, the User Manual indicates that the card is Re-Rormatted.
What happens to the update files?
Are they needed on the disk...
