If you have multi-CSC firmware, you can use OXM. There are several reasons to change the device CSC. If you have a carrier-locked device, changing these settings will unlock it. If you have a device from another country, then you can change the language and device settings according to your country. APN Settings and pre-installed applications can also be changed, and changing the CSC resolves all these issues. You can then proceed to flash the firmware of your country of residence. You can also use it to get the Call Recording feature in a region where it isn’t available.

There are many methods to check CSC. Dial *#1234# in your phone app, and you can see the active CSC code for your device. The first three numbers that show up after your device model make up your CSC number. You can also use third-party apps like Phone Info from the Play Store. Your Settings menu will also have this information in the About Phone tab. You can find your CSC number from the “Service provider SW ver.” tab.

Note: You will lose all your data since you have to unlock your bootloader. Make sure you have a proper backup. Changing CSC and flashing a different firmware using ODIN runs the risk of soft bricking, and we’re not responsible for any damage to your device.
