Please, correct me if i'm wrong, but sysConfigTool can't install unsigned stuff unless you have sigpatches. And, the Brazilian method is as follows
- Download content with some sort of NUS grabbing tool.
- Grab a ticket and place it in the contents.
- Install using any form of title installer.
The method itself never states that a legit ticket is required, just states that one is required. SigPatches could be a factor, it could not. The Brazilian method itself is just installing a dump with wupinstaller.
