I think you need to restore the system software by using either Samsung kies or downloaded firmware from sammobile with the phone plugged in and booted into download mode with the application called Odin to flash the firmware onto the phone.
Instructions on how to do so are on the firmware download pages from sammobile website.
Make sure you download the correct one for your phone model number.
