For example, if your Samsung phone doesn’t have a feature like native call recording, or Samsung Pay doesn’t work on it, changing the CSC can help you. If you’re looking for a way to change the CSC of your Samsung phone, we have 4 methods that can help you do that.

While flashing the firmware on your Samsung device using Odin, you must have noticed 2 CSC files. If you are confused about whether you should flash the CSC or Home CSC file in Odin, please read our explanatory guide on the topic.

How to Check the CSC Code of Your Samsung Phone

It’s very easy to find out the current CSC of your Samsung device.

  1. Open the Settings on your device.
  2. Go to About phone > Software information.
  3. Look for Service Provider SW Version.
  4. You’ll find the CSC of your Samsung Galaxy phone mentioned csc code structure explained

If the CSC of your Samsung device is OXM it means it has Multi-CSC firmware installed on it. OXM is a group of CSCs that contains multiple sub-CSCs inside it. It means that you can easily change the CSC of your Galaxy phone or Galaxy Tab.

If you are curious why the INS CSC is mentioned four times (INS/INS,INS/INS)  in the screenshot above, here’s the explanation. There are two formats in which CSC is shown on Samsung devices and it depends on the fact whether your device is a single or dual SIM variant.

  1. Single SIM models: XXX¹/XXX²/XXX³
  2. Dual SIM models: XXX¹/XXX,XXX²/XXX³

The first CSC value refers to the Active CSC¹ on your phone. The middle part shows whether your phone is a single or dual-SIM² model. The third and the last CSC value shows the country or region for which the phone has been manufactured³. Thus, INS/INS,INS/INS, shows that the active CSC on my Samsung S23 Ultra is INS; it supports 2 SIM cards from any Indian operator; it has been made to be sold in India.

If you own a Samsung phone released in 2022 onwards, the code (*#272*IMEI#) to change CSC might not work for you. Thus, if you want to change the CSC of your Samsung Galaxy S23 Ultra, for instance, you will need to use SamFw Tool for Windows. SamFw works best when your Samsung phone has a multi-CSC. Follow the steps given below.

  1. Using this method won’t reset or wipe your phone’s data, invalidate the warranty, or trip KNOX. However, we still suggest that you back up all your data before you start.

3. Change CSC on a Samsung Phone without Multi CSC using Odin

This method is a little complicated and requires some effort.

The CSC configuration on your Samsung devices determines if it is unlocked or locked to a network provider. While it’s possible to use a different SIM card on some carrier-locked phones, there are others on which you just can’t use a SIM card from any other network operator than the one it’s locked to. Suppose you own the Verizon (VZW) variant of the Galaxy S20 and you try to flash the CSC meant for TMO (T-Mobile), you’ll either get an error in Odin, or you’ll end up with a soft-bricked phone.

So, in what cases a CSC change might help? In case you live in Italy and purchased a used unlocked phone online from a Russian user, you may not find the Italian language on your device. By flashing a firmware binary with ITV CSC, you can have the Italian language on your phone. Also, if you use a phone with Russia CSC in Italy, you won’t receive software updates from Samsung.

Note: If your Samsung phone has a locked bootloader or is SIM-locked, you won’t be able to change the CSC of your device.

If you want to change your phone’s CSC, here are the steps:

  1. Download a Multi-CSC (OXM, EUX, INS) firmware. You can use the Frija Tool for that. Since Frija works with Windows only, you can use Samloader to download Samsung firmware on Mac or Linux.
  2. Download the latest Samsung Odin tool and unzip it.
  3. Install the latest Samsung USB driver on your PC.
  4. Extract the downloaded firmware ZIP on your desktop.
  5. Launch Odin.
  6. Turn off your device and boot it into the Download Mode. You can do so by pressing and holding the Volume Down + Power buttons at the same time for 2-3 seconds.
  7. Connect your phone to the PC using the USB cable provided by Samsung.
  8. When your device is detected by Odin, click the BL, AP, CP, and CSC sections and add the corresponding firmware files to them. Do not flash the HOME CSC but the CSC (only) binary.odin firmware flashing steps
  9. Click the Start button on Odin.
  10. When the firmware is flashed, your Samsung device will reboot automatically.
  11. Disconnect the USB cable.

Done! You have successfully changed the CSC on your Samsung Galaxy device. Alternatively, you can also flash the CSC file only but in that case, make sure you download the firmware for the same software version that’s already installed on your device. You’ll still have to download the full firmware because you cannot download the HOME CSC or the CSC file separately.
