PPCGeeks - Problem with auto rotate

I have sometrouble with auto rotate of my screen, if it stay on auto rotate it turns everytime to the wrong direction.
This happenedafter I flash a new firmware in with “flash10.1-android2.2.rar”.
This was necessarybecause my tablet did not start up and there was no recovery image.
Every thingworks fine except auto rotate, I have to switch it to manual to keep it stable.

Is theresome way to calibrate the auto rotate, or is there any app which can do this.
