I have the same problems but when I uninstal ios249 with wad manager I get
error 1017. error 1017, error 1017
Have tried everything and also anytitle deleter and it will not for the life of me uninstall the wad.
I wanted to use any region changer to change the console region but the same error 1017.
can't seem to find much about this. :-( any info you know would be appreciated!
