Camera software updateThis is the procedure I had to do to update the camera softwareRemove 256gb cardUse 32gb card to load update file Change name to INNOVVC5.binpassword When updated 12345678Replace 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.
