Hi , This is the first time on this site. I have a problem downloading the latest firmware onto my X T3. After I drag and drop the firmware on to my memory card, reinstall it back into the camera I get a message saying , Firmware not found in slot 1 turn off camera. If I down load using the phone app. After pairing the camera with the phone and downloading the file onto the phone. I get a message saying camera is processing try later. After trying both these methods dozens of times without success I'm stuck, please help. Cheers Paul.
