I think you are following a guide on another forum. There it says something about UP0001-gametitleid_00-0000111122223333.pkg
You should ALWAYS use the 00 after the gametitleid like this: gametitleid_00-0000111122223333.pkg
In the guide is a small typo where it says gametitleid_01 <-- That 1 should be a 00.
After that, it should work
