Do you know if your phone was locked to a network to start with?
If it was locked to a network you have to unlock before installing another non network, stock firmware.

To find your original firmware, open Kies.
Remove battery from phone and connect to Kies.
Enter phone model and serial number.
Follow instructions until you get to a firmware and 3 letter code.

This is the phone's original firmware.
Copy and then cancel.

Your phone will not register on the network as it is sending the wrong IMEI number.

You now need to restore your EFS (as the 4.3 firmware changes the file format)
With the old EFS foder, install the original firmware for your phone.

With a lot of luck this will also restore your IMEI.
