Jelly Bean 4.2 Airplane Mode Helper for Root Users.

This application does NOT work on Android 4.3+. Android 4.3 compatible solution is called "Jelly Bean 4.x Airplane Mode Helper", it requires Xposed framework, it is available on developer's website and XDA Developers forum.

This application allows other applications to control airplane mode on Jelly Bean 4.2 (Android 4.2) devices/ROMs exactly the way it was possible before Android 4.2.
This is generic helper - most applications capable of toggling airplane mode on pre-4.2 versions of Android are supported.
The only unsupported applications are those that explicitly detect Android 4.2 and disable/hide settings that control airplane mode (and usually show some kind of notice about Android 4.2) in GUI. If you encounter such applications, please notify their developers about this workaround (ask them to bring airplane mode options back and display a warning on Android 4.2+).
Additionally Jelly Bean 4.2 Airplane Mode Helper offers Locale/Tasker plugin for airplane mode control.

Jelly Bean 4.2 Airplane Mode Helper is distributed "as is" without any form of warranty. It is user's sole responsibility to obey all regulatory rules about usage of airplane mode and not use this application in places/situations where such rules exist.
