Thanks to Don Hergert for discovering it and Steve Sanders for publishing it, there's a new wa to upgrade the firmware of your Coolpix 950 / 990 by simply placing the firmware file into a special directory of a CompactFlash card, inserting it into the camera and turning the camera to Play. Why on earth Nikon didn't make this method publicly available is beyond me, it's much more straightforward (and less prone to mistakes). Note - you'll need a card reader to upgrade using this method.
