1. If you have old or any other flashplayer, uninstall it;
For further manipulation, I used RootExplorer
2 . Copy ,,Flashplayer.apk" to the folder /system/app and set permissions to "rw-r - r -
3 . In folder /system/lib create a new folder name "plugins". This folder permissions set to "rwxr-xr-x"
4 . In Folder "plugins" , create another folder name "com.adobe.flashplayer" and just change permissions to "rwxr-xr-x"
5. Copy ,,libflashplayer.so" to the folder /system/lib/plugins/com.adobe.flashplayer and set permissions to "rwxr-xr-x"
6. Reboot the device .
7. After restarting the application menu, run flashplayer.
If you see settings page flashplayer, then it is working
Tested and it's working on my Lenovo K900
