Basically you want to exchange the filenames, so...go to mygame_complete.html and RENAME it to 404r.html and then name 404r.html to mygame_complete.html . After that repackage the apk and it should be fixed. Now the logic in this is that, the game tries to send you to a 404 screen but because the game is NOW named the 404 screen it gives you access to the app
