Hello! Today I brought a used Wii U Deluxe (in firmware 5.3.0 U). But I've been searching, and I cannot upgrade this console to a specific firmware (in this case, 5.5.1) - like 3DS - only to newer. Well, Can I run any CFW or exploit into Wii U with firmware 5.3.0? If yes, what tutorial is better to execute? In ours opinion, is better jailbreaked this console now or wait for update of exploits? Thanks for helping!
