i tried to update the firmware on my nikon and downloaded the file, copied it to the memory card and no option to upgrade is appearing. i have done this several times and am getting extremely frustrated. help?
Did you transfer off all the images then format the memory card inside your camera? After that copy the file D50101.bin to the memory card. DO NOT copy the file into the DCIM folder, just copy to the card itself.
Re-insert the memory card, turn on the camera. Select Firmware version from the setup menu and there sould be instructions displayed on how to upgrade the firmware.
After the upgrade is complete, turn the camera off and remove the memory card. Turn the camera back on with the card removed, and access the Firmware version in the setup menu to confirm its been upgraded. After confirming that the firmware has been upgraded, be sure to turn the camera off and leave it off for five seconds or more before using it. (Do not remove the battery or disconnect the AC adapter before five seconds have passed.)
