Thanks guys for the fast reply.
Call me stupid, but it still doesn't work. I started all over again. Formatted card in camera with wall charger, connected camera with provided short USB cable to pc, copied new v3.3 bin file to camera, mass storage mode on screen, disconnect camera from pc, connect to wall charger with provided long USB cable, no mass storage on screen, no flickering record button and camera starts normally. Still on v2.06 firmware. By the way, bin file is copied to the card......?? I cannot find mass storage mode under menu. What did I wrong now???
