Warnings
If you have followed the OLD guide you need to rename the original CA27.cer to CA27.cer.bak and (my) CA24.cer to CA27.cer and you have to restore the old CA24.cer, by renaming CA24.cer.bak to CA24.cer This is needed since some games use the original CA24.cer If you lost original cert, you can take it here
