I have looked through the definitive and noob guides on here... The last time I had a wii u, you had to use browser exploit and the very first version of loadine which was good for it's time. My Wii U is on 5.5.1. I would like to do permanent cold boot via DS game. Do I need to update to the latest 5.5.4 to access eshop and obtain my DS game (presume I do). Does 5.5.4 work with the DS method for cold boot? For some reason even looking on here and at wiiu.hacks.guide these questions aren't answered. If someone has used a guide recently and recommends one to do the above I would highly appreciate some assistance please.
