AllWinner A20/A23 Demo Lock Removal Tool by Fsebentley and HcH

This will replace and remove files to get rid of the CloudsService trojan
that appears more often these days on AllWinner tablets. It's identified as:

If your AllWinner shows a red DEMO text you can unlock this demo mode by 
using one of the DemoFix funtions. A backup will be made before actual 
modification are made. To restore the backup, rename SystemUI-backup.apk 
to SystemUI-A20/A23.apk and restart the corresponding function.
