The LG535 has dloadfun*Index.map files for ringers and images, along with a map file for what Jave apps are installed.

Now, remember that these are
byte-spaced and trying to edit them in Notepad
will break the file. Ensure you've got yourself a decent hex-editor and
make backups before editing. So many people forget to make backups and then render their
purchased content useless.
Any issues, let me know.
