The V10 is the KITKAT version and the V20 is for the Lollipop, then there's a letter, that is little updates, download the one with the "last" letter
The D331, or D335, or D337 is the version of your phone (I own a D331 and right now there isn't a Lollipop firmware for de D331 so I have install one from the D335, and there is no problem, my smartphone works perfectly)
