Tell the "Surface" to forget everything it knows about the hardware and start from scratch.
- Boot the Surface Pro 2 into Windows 8.
- Hold the volume rocker in the up position and hold down on the power button until the Surface shuts down. Continue holding down both the volume up and power buttons until the Surface turns back on and show's the "Surface" splash screen. Continue holding down both buttons until the Surface Pro 2 turns off a second time. Release both buttons.
- Turn the Surface Pro 2 on again. If you've done everything right, you should see "Updating Your System" appear on the splash screen along with a percentage counter. Don't touch the Surface until it completes this process and you see the lock screen.
- Login. You should have rotation and tilt again.
The Android-x86 community is also busy testing their Android 4.3 image out on the Surface so you might want to see what develops from there as well.
I am figuring that as more users become interested in installing Android on their various Intel devices, this issue, or others like it might occur. The solution above is very straight-forward and can save you hours of time trying to get technical help from your OEM or other discussion forums. I would suggest finding out how to perform a "hard reset" for your device just incase you find yourself needing it.
