Camera software update This is the procedure I had to do to update the camera software Remove 256gb card Use 32gb card to load update file Change name to INNOVVC5.bin password When updated 12345678 Replace 256 card
A also decided to use a different card to my normal recording card, 32gb the same as you.
Bit of a faf but it worked, not sure why it can't be updated via the app but there you go.
Please check again the bin file name, it should be the C5/K2.bin.
No C5(1)/(2).
