If your console is version 5.3.2, it has a file where the version number is stored (the "version" file contain the text "5.3.2")
you install the "version file" which contains the text 5.5.0, and the game only look at that file to check your current system version, so the game thinks you are on 5.5.0 while you really are on 5.3.2, only the "version file" is updated. This is called spoofing.
Now, if you want you can install another "version file", but only higher, for example 5.5.1
You can't go back and reinstall the file which contains the text "5.3.2".
