Okay, to me this is everything that is blocked.

BootMii as IOS and Boot2 are GONE!
DVDx gone.
HBC gone.
Preloader gone but updated.
cIOS249/222/223 ONLY removed, not 250(Clone of 249) or 202(USB2.0).
Bannerbomb deleted.
ALL IOS'S have been stubbed and updated due to boot2 has been updated to boot2v4(LU64) no downgrading...

Don't update. Unless you want a Homebrewless Wii and an unfixable bricked (If it gets bricked) Wii.
