Hi TinTyn! The link Vincenzo provided is only working for A81E.Did you flash the "last NodusRom" from Betolley to a A81G?Than the file "/system/lib/hw/
sensors.omap3.so" is already renamed to "
sensors.omap3.bak" by Betolley and you will have to rename it back to "
sensors.omap3.so" to get Rotation working again.
You will need RootExplorer to do this.
@Vincenzo: You should update the information on your site for the different devices.
I also recommend to use an alternative Launcher like LauncherPro for the full Rotation-Experience.
There is a new Firmware version 110221 out now. If you (like me) have seen the issue that your device often does a sudden Reboot while installing something you may want to flash this new Version.
You can download the preinstalled Apps from Witstech but most of the Apps are old versions:http://bbs.witstech.com.cn/index.asp?boardid=13You will find RootExplorer under "Other Tools/Application Software".
The downloaded Rar-files comes without a file extension so you need to add ".rar" to the filename.
