So the purpose of this thread is to explain what are those sales code that samsung uses...

To change the CSC enter *#272*xxxx# where xxxx is the current time (by the phone) ex: 06:30 = 0630, 20:25 = 2025

If you have information for any of these codes, please share it so i can update the thread for future use.
