How to Change CSC (Region Code) for Samsung Galaxy Models

What is the CSC (Consumer Software Customization) code?

The CSC code contains information about software packages specific to a particular region, carrier branding and also APN settings for data connection.

In this way, unless the PDA, PHONE and CSC codes do not match correctly, you will not be able to update your device over Samsung Kies or via OTA"

If the PDA, PHONE and CSC codes do not match correctly, Samsung Kies software will display this message in "Firmware information" section when you connect your Samsung device to PC

"Your device's current firmware version is not supported to update firmware via kies."

And normally If the PDA, PHONE and CSC codes match correctly, Samsung Kies software will display

"This is the latest firmware." or "New firmware is available."
