sooooo i dont post ever but i might have made a very big mistake. my wii u is on 5.5.4 and i was using non coldboot haxchi but i wanted to use pretendo. i looked and saw that i needed the new aroma tiramisu thing so i uninstalled haxchi and decided i should probably update. but i got an error code and remembered i deleted the update folder but i dont have haxchi anymore so is there a way to get everything fixed or have i messed up my wii u? and is it possible to get tiramisu on 5.5.4? or do i need to update? thank you so much in advance! and sorry for the bad punctuation
