   • B3000111.bin :  the B firmware

4. Connect the camera to the computer via USB cable (be sure that the camera’s USB item in the setup menu is set to Mass Storage ), or use a card reader, and copy the downloaded A firmware to a memory card formatted by the camera and inserted in the camera or card reader.
