I am the second owner of a X-E2S. I just tried to update the firmware to v1.11. I fresh-formatted a SD card, downloaded the firmware on my MacBook Pro, copied the firmware to the SD card, properly ejected the card from the computer, put the card into the X-E2S, switched on the camera holding the DISP/BACK button, said to upgrade body firmware, camera said no firmware on card. I verified the 1.11 firmware was indeed on the card. Further investigation shows that the Body Version says 4.0. Can I assume the former owner upgraded the camera with x-E2 firmware? Is it possible some early X-E2S were shipped with X-E2 firmware? Should I try to update to X-E2 4.11 firmware? Hoping someone here has input or been down a similar path.
