Can you please attach your modified file so as to be used (replaced) simply by me and others because it's a very hard process to combile and decompile this file ....? thanks in advance .
OK, Your phone is rooted, and have CWM, then make backup.
Here is my LGSystemUI.apk; https://yadi.sk/d/ZaMvGicsW9xZx.
Just copy it (and overwrite) in system/app, set permissions -rw-r--r-- (like other apps in folder), delete LGGystemUI.odex (thats why must make backup), and reboot.
Good luck...
