Follow the path below: Path: cnlaunch\X431PADV\assets\StdCfg.ini
Open StdCfg.ini (ES Note Editor or HTML Viewer available)
Find OnlineFlash and Flash
Change OnlineFlash=0 to OnlineFlash=1

You can also unlock the access to the Android system so that launch can be used as normal tablet (although that requires use of android adb and apps can only be installed via USB cable).
