Updating d300 firmware
A Nikon-approved memory card that has been formatted in the camera (note that all data on the memory card will be deleted when the card is formatted; before formatting the card, back up any data you wish to keep to a computer or other device).
Important Only one of the two sets of firmware (A or B) can be updated at a time.
Some later production models may have been shipped with 1.02/1.00. The 1.02 "A" was released for the 1.00/1.00 models to get to what current production was and to accomplish whatever fixes the 1.02 "A" did.
Do not turn the camera off, remove or disconnect the power source, or operate camera controls during the update.Use separate memory cards for each set of firmware, or update firmware A as described below, then format the memory card and repeat the process for firmware B.The camera will appear in “Computer” (Windows Vista) or “My Computer” (Windows XP) as a removable disk.wrote: I don't know aobut being able to revert back to 1.02/1.00.I believe that the first original cameras came with 1.00/1.00.
