choejor: Hello Nikonians, I just download the Nikon D4 firmware upgrade and tried to install it. I have downloaded the instructions and followed all the steps. But It never worked for me. The upgrade option is not at all showing. I did everything that has been mentioned in the instruction. Any help will be highly appreciated.
Choejor, I had the same issue, the "Update" line never appeared. I downloaded the update several times into my CF card with no luck. Then I read that the CF card must be designated as the Primary card in the D4. If you have the XQD card as primary, the D4 will not read the update from your CF card. So I designate the CF card as primary and the D4 showed the Update option in the Firmware Menu.
