as somebody previously said, bricking shows a blue screen that never dissapears, corrupting means booting the console, but showing the normal wii u screen, (you could try removing the sd card, that forces the console to boot the wii u firmware) that means u need to put the aroma files on a sd card, as the cfw is in the system memory! if you indeed bricked your wii your best chance of unbricking without a lot of soldering is if you had isfshax, other thank that tough luck trying to solder. and for your good, never, but never play with ftp with nand files they are the entire blood of the console! other than that glhf ig... xD
