Nikon USA has posted a firmware upgrade for the D4. Below are the changes:
"When a still image was captured while viewing existing images in playback mode, the monitor turned off, the memory card access lamp glowed steadily, and, in some rare cases, the camera ceased to respond to operations. This issue has been resolved.
When network functions were used with certain settings applied, RAW images were also transferred when Network > Send file as was set to JPEG only. This issue has been resolved.
When an option that utilized the main command dial was selected for Custom Setting f15: Playback zoom, and an image was zoomed in or out with playback with certain settings applied, shooting shutter speed, aperture, and exposure compensation settings were sometimes changed. This issue has been resolved."
I have never done an update. It seems that I will be doing the updates for the D4/D800. I am nervous about this so any help is much appreciated. I read the directions and it seems that I should use a card reader. Can these updates be done by plugging the camera into the computer? Also since the XQD card is slot 1 for me on the D4 -- is this the card and reader that I should use (if I can't just plug the camera into the computer).
Thanks much in advance (apologies if already asked and answered).
Instructions are given with the update. It's not hard and not risky. Make sure your battery is near fully charged because the update takes several minutes and you could have serious problems if power fails mid update.
You extract a BIN file from the downloaded file.
You copy the BIN file to a memory card. You need to use the card than goes in the slot you have selected as primary. I do this with my card reader, but you should also be able to do this with the camera connected to your computer. The file must go in the root directory of the card, not inside any folder.
Go to the Firmware entry of the Setup menu and select Update. Note that the update option only appears if the correct BIN file is in the root directory of the card.
After the update is finished you can delete the BIN file from the card.

I'm guessing that you already did the update, but the XQD card works fine in order to do the firmware update as long as it's selected as the primary slot. The primary slot is selected in the "Shooting Menu".
As already mentioned definitely read AND comprehend the instructions before starting.
FYI: The root level is the first window you see when you click open the XQD or CF card. When you click open the card you'll also see the DCIM folder (and a Nikon DSC file) already on the root level of the card. Ignore them.
Otherwise just follow the instructions.
I don't know if you can just plug the camera into the computer to do the firmware update. I doubt it.
As to using a card reader, I would do as instructed. The camera might detect the addition of the firmware and start processing it while still tethered. But I always transfer with a card reader and use either Windows Explorer or Macintosh Finder.
