Hello Guest,
You can reset your phone to restore all default settings. You need to backup all the phone data. After this, point to Menu>Settings>Privacy>Factory data Reset.The phone shows a progress dialog box and reboots automatically after completion of the Factory Reset process. Now, the slider mechanism will be restored upon restart. Thank You. Hope this helps.

Hi,
The problem with the phone is that the device might have some framework problem and that which is causing the "Notification" panel to got disappeared in order to solve the issue you have to reboot the phone and see that the problem is solved if that is not solving the problem then the only way is to restore the SystemUI.apk that can be done by installing the whole ROM again in the phone and so that the files are flashed again and everything will be restored.
Hope this Helps.
