Just updated my 2DS to 11.9.0-42U and now I'm getting a message saying "An error has occurred. Please save your data in any software currently in use, and then restart the system." I also was getting this message when I was running 11.8. I am running the latest 8/21/17 release of this payload.
This was my only entrypoint for getting into Homebrew. Does it no longer work?
