Hacking Homebrew -11 bug on Homebrew exploit

[MohsinTeddy_]

I have been modding my wii u and recently I downloaded the TetrisU app from App Store and when I pressed select I was greeted by a black screen with the number -11 in the top left corner. I haven't launched hombrew since but my wii u and vwii still work.
Also when it was showing the number -11 the wii u was not registering inputs and wasn't shutting down. I had to turn off the plug.

I checked it out but there is nothing about -11
