[Q] Flashing splash screen (shows image of snow) topic

So I was trying to flash the splash screen when I accidentally didn't rename it from the png file to an img file. Now whenever I boot the phone it shows an image of snow and then the bottom is black. I'll try to take a picture later, but did I mess up my phone for good? When I try to flash other .img files it still gives me that snow/black splash screen.
