During the procedure, the device !!!WILL PERFORM A FACTORY RESET!!!- Root your device.- Open a terminal emulator on the device.- Type the following commands (let the terminal application gain root access when you get prompted):$ su# am start -a android.intent.action.MAIN -n com.sec.android.Preconfig/com.sec.android.Preconfig.Preconfig- You will get a window with a list of CSC codes. Select the one corresponding to your device and stock firmware, and push the button INSTALL.- The device will reboot, and !!!WILL PERFORM A FACTORY RESET!!!- That's all folks.- (Now go mess up things again, and again...)
