Normal firmware update from nsu are just a patch on you previous firmware.
Flashing means that your entire firmware will be erased and then you will put new one.
But it can be very dangerous ,because there was some problems with cable drivers so you need to do it on clear system without nokia pc suite and other stuff installed..
Or else you phone can be bricked...
