You need winflasher and use this http://talk.maemo.org/showpost.php?p...24&postcount=2

After that you can get new "libmeegotouchviews-modified-default.css"
Correct me if I am wrong, I have never used R&D Mode.

If you dont know how to do that you should reflash your phone:http://talk.maemo.org/showthread.php?t=82693
