So after some careful reading i decided to try the kernel exploit on my 5.5.1 wiiU but when i try to load any of the three available games: hyrule warriors, captain toad, star fox zero i get error 199-9999 and the wiiU make me reboot, i tried format my SD again, checked the files on it, loaded the kernel 10 as always, and tried to check on google but i can't find anything usefull, just infos about updates.
