Ok,
download the zip. Extract on your pc. Connect the pc to your phone(usb mass storage mode). copy the files to sd or sd-ext from the pc.
On the phone, open root explorer. path to sd card (wherever you put the files). hit menu, multi select. Select the four files, then copy. Path to /system/app, toggle read/write button at top, then paste.
Now you will need to change the permissions for each file. long press the file, scroll down to permissions, press. you will get a 3x3 grid. make sure a checkmark is placed in all three of the first column, and the top cell of the second. the rest should stay grey (unchecked). do this for all four files, change read/write at top to r/o, exit reboot.
That will hopefully do it.
