Hello I recently picked up a wii u and have read up on installing cfw and have done alot of mods in the past but this will be my first wii u. The wii u I have is on 5.4.0 U and after reading I think the best approach would be to do a system update to 5.5.2 then proceed with the haxchi method. Any advice would be greatly appreciated if I should go another direction. Thanks
