❓ What is CSC?
CSC (Consumer Software Customization) defines the regional settings and carrier-specific features on a Samsung device. It controls:
⚫Available firmware updates
⚫Pre-installed carrier apps
⚫Network compatibility (VoLTE, 5G bands, etc.)
⚫Samsung Pay, Call Recording etc..
⚠️ Important Notes
⚫You may lose access to region-specific features.
⚫This process may void your warranty in some regions.
⚫Proceed at your own risk.
✅ Requirements
⚫A Samsung Galaxy device ( carrier-unlocked)
⚫Windows Computer
⚫Data Cable to Connection between galaxy and Windows Computer
⚫Internet Connection ( for download the required tool )
⚫Patience – some steps require reboot and setup.
I will explain the easiest method of CSC changing, there are other workarounds but this is the easiest way:
1. Disable Auto Blocker ( New Galaxy Devices has this security feature )
- First Go to Settings > Security and Privacy
- Then toggle off Auto Blocker
2. After go back and Go to About Phone > Software Information
- Tap 7 times rapidly on Build Number to open the hidden developer options menu
- After hitting give the device lock screen credentials to enable developer options
3. After enable it go back to settings again and you can see new menu called Developer Options has been enabled
- Go to Developer Options andturn on USB Debugging
4. Download SamFW tool
5. Install the Software on you Windows PC ( You need to temporary disable the windows defender )
6. Then connect the Galaxy Device and Your PC using the Data Cable
- After connect in the Software it will show as follows
7. On other hand in the Galaxy Device there is a connection request
- Allow the connection
8. After it connects Choose Samsung and Go to MTP and Select Change CSC form the menu that shows device supported CSCs

- If not you have to manually flash the firmware for the CSC required region to gain OTA updates.
- In Sri Lankan market there are mostly having OXM multi CSC devices. ( KSA, EUX, INS, XSG all included ) - can easily change the CSC to SLK
