Help patching ios 80 need walkthrough

Why are you patching ios 80? Do you have bootmii as boot2?

 

afaik, patching ios 80 enables playing games from sd card in the official manner, eshop games that is. personally, this is not something I did, because it's easier and better to use emunand and neek.

 

Sorry, only realised after posting. Personally I’d avoid it if possible using options godreborn suggests.

There is a patcher, but I haven’t used it myself:

In terms of recovery, there are potential options but the best option is to avoid the risk if possible:

Make sure to have a backup of everything both vWii and Wii U anyway.

 

if possible, I'd get neek2o. it has more options than neek. neek you can make yourself, but neek2o requires leaked files, which can't be shared on here as they contain official code I believe. I have neek2o, and it works flawlessly. there are a few drawbacks like the wii u rebooting into wii u mode after exiting if the system is designed to return to usb loader gx or something. with usb loader gx, you can create an emunand and inject wads without a wad homebrew. both of those things are in features.

 

They’re in the hacking guides:

Wii U:

I strongly suggest you use emunand. you're limited with the sd card. emunand can hold unlimited titles.
