Hello, I successfully performed the update a couple days ago on my D3300. I started out with v1.00 before the update and had v1.01 afterwards. The instructions also specify that the BIN file must be copied to the root directory on the SD card or it won't be recognized. Sorry, I know these are dumb questions, but is there any chance that your camera already has the latest version? If not, did you copy the .bin file to the cards root directory?
