I'm at the point where i'm dumping nand. I put 64gb sd card with cfwbooter and fw.img into my wii u. fw.img is in root. When i start cfwbooter from homebrew launcher it throws me back to the home menu. i'm not sure at what point am i supposed to tap the power button, also on console or the gamepad? And is there any risk of brick during the nand dumping phase?
