Don't forget the licenses for the picture viewer and travel application. 
Anyway, you can easily use options in the SYS.TXT, I think most functions will work from the R3 version. This way I disabled the annoying beep before every announcement, and also disabled menu animation for instance. The only thing I can't get to work is the backlight problem, it always turns off after a few minutes. It only stays on when I change the backlight setting on the device itself.
Also the data file being encrypted is a problem at the moment, I can't modify anything yet.
