You can choose "Rotate the contents of the screen"
from Settings -> Display.
(could also be adjusted via pull down menu)
Then open a terminal, issue the commands:
su
setprop config.override_forced_orient true
stop;start
If you want to keep it persistent, you should
modify function init_hal_sensors()
in /etc/init.sh, add your device id
or just change has_sensors=false
to has_sensors=true.
