There will no release of any kind of NVRAM patch on the fly, and even a ARM patch on the fly, if they release it WIIU is DEAD! The developers know it, the hackers scene seens more focus on the service to nintendo than a service to pirates bay, so, do you think it will solve to release what they got, no!
@smealum know the correct way to destroy one system, and if he release the kernel hack it can be used to do whatsoever you want to WIIU, so, it is the same as PS4 hack, its a true true root power.
Why not release it?
Simple, piracy will destroy the WIIU
This kind of hype cannot be undone, its the same as have been done in the PS3 scene.
The difference are how nintendo Internet works, so, it is not as PSN and they need to find one way out to kick the CFW/HACKED consoles from their network. (the keys can random create new IDS and patch the banned consoles back)
Why release it?
Homebrew world doesn't really exist.
It is all about piracy!
So, the 5.5 hack its not only this, is a full hack to a system, same as PS4 hack, same as linux/bsd root hack.
