Forgive me if this is somewhere in the forum but i cant find this info. Trying to update my af100 firmware. I put the firmware folder called Private on the sd card at the top of the folder structure, place the patch in there also then eject it and insert into camera. It gives me a check card message. I am using OSX to do the update. Have also tried putting the folder named vsi5257j on the card also, no joy. Any tips from anyone would be very much appreciated.
