How to rotate screen orientation? fakerotation not work

[plightsup]

Hi,
I have MK908, MK809III, CX919II, and CS968. Because i will use the device in vertical orientation, screen rotation is needed.
The build.prop parameter "ro.sf.fakerotation=true" work on MK908 and CX919II, but not MK809III and CS968.
I tried several rom, "fakerotation" make the device stuck on bootanimation.
It looks like something else in system should be modified.

After some google searching and trial & error, the screen can rotate now. The method is from the thread below. I edit service.jar in framework.
