When you extracted the firmware package, You will notice that there are two CSC files, One file starts with CSC_Oxxx and the second starts with HOME_CSC_Oxxx.

If you are installing a firmware with the same country code (Or carrier) like your device already has, Then you can select the HOME_CSC_Oxx file in the CSC field, But in case you are installing a firmware with different country code (Or carrier) then you have to select CSC_Oxxx file instead.

The Odin3 program will become unresponding after selecting the big firmware's files like AP and CSC files, That is normal because the Odin3 program needs to check the MD5 value of the selected files, So be patient.
