Steps to Change CSC Code on your Samsung Galaxy device

We recommend you install the File Explorer Root Browser app from the Google Play Store; [googleplay url=”https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree”]
  • Now, you need to install another application that will tell you the information related to the current CSC code of your Samsung Galaxy device;[googleplay url=”https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo”]
  • Once both the applications are installed on your Samsung device, open the Samsung info application and you will see some information related to the CSC you have on your device.
  • Then, open the Root Explorer application you have downloaded and mount system as RW (read-write). You will be asked to grant SuperSU permissions, go ahead and grant the permission.
  • Now, navigate in the file explorer to /efs/imei/  and open the mps_code.dat file in a text editor. (make sure to take a backup of the system file first)
  • You need to change the text in the mps_code.dat file to the CSC of your device and save it.
  • Then, navigate to /system/CSC folder and search for the CSCs that are available for your device. (you will see folders like BTU, DBT, etc)
  • Copy the content of your choice of CSC and paste it in /system/CSC (for example, copy DBT/system/CSC to system/CSC.
  • When you in the /system/CSC, make sure all the permissions are correct and set to 644 (rw-r-r-).
  • Now, reboot your Samsung Galaxy device. (sometimes it might take a bit longer so, wait!)
  • Open the Samsung Info application and check that you will now have changed CSC code for your device.

That’s it! You have successfully changed the CSC Code of your Samsung Galaxy device without wiping off the data. Note that as already mentioned, you need to have root access on your device to go ahead with the above method. Moreover, now you can grab the firmware update if a new update is rolled out for a different region other than yours.

Method 2: Unlocked Bootloader Method

  • Make sure that you have unlocked the bootloader of your device.
  • Now, flash the TWRP Recovery on your device.
  • Flash a custom ROM on your device.
  • You need to root the mps_code.dat file which you will find in the /efs/imei/ to the CSC you like.
  • Once the above step is done, relock the bootloader.
  • Now, you need to re-flash the stock ROM on your Samsung Galaxy Device.
  • That’s it! You have changed the CSC code of the Samsung device.
