Once you get ahold of the firmware file your set.
Format an SD card using your computer (or the I60) and copy only the firmware file onto the card. Next inset the card into the cam go into the cams set up and select which firmware it is you want to upgrade. If I remember right the Moultries have type1 and type2 firmwares on them. There is an option to upgrade under each type.
I'd call them and get their opinion first because you could damage your camera if you try flashing with the wrong firmware.
