You might want to tell people to just update. Both wiiubru and salt are working on IOSU and stated it will only work for 5.5.1. Considering their is only 1 disc with 5.5.1 (paper mario color splash) you should tell others to update before it is too late. (That and so people will stop asking things that can be fixed by updating).
Also on 5.5.1 the exploit has 100% boot rate while older firmwares take multiple tries.
This thread is pretty outdated. You should add that a IOSU exploit and CFW is out (no sig patches)

The Brazilian exploit, ticket dumping, and others are out but no info on here.
You should really update this as this would be the guide most noobs will follow first.
Also you are kinda missing the tool you released for VC injection
