For the those not knowing which files to use, here is how I did it.
Open Odin, connect your phone (while in download mode) and do the following:
1-Click on "Bootloader" and select the 'BL_****' file.
2-Click on "PDA" and select the 'AP_****' file.
3-Click on "PHONE" and select the 'MODEM_****' file.
4-Click on "CSC" and select the 'CSC_****' file.
Then click on "Start" and wait for it to finish.
When finished, Odin will display a "RESET" message and the device will reboot automatically. After its done, it might freeze on the "Samsung" logo so just disconnect the device and reconnect it, Odin will display the "Pass" message. Re-disconnect your device and reboot it and that's it.
Make sure you backup your device first!!!
