How To Change CSC Of Samsung Phones Without Rooting

If you are wondering how to change the CSC of your SAMSUNG Android phone without rooting, you shouldn’t skip this post.

Apart from how to change the CSC on your Samsung phone, you will also find some useful info related to CSC and changing the CSC on your Samsung Android phone.

Before we begin, let’s make some things related to changing CSC on Samsung Android phones clear.

What does CSC in Samsung phones mean?

You might have wondered, what is the meaning of CSC and what do you need to know about Samsung CSC codes.

CSC is an abbreviation that stands for “Consumer Software Customization” or “Country Specific Code“. These two meanings, Country Specific Code & Consumer Software Customization are where the function of the CSC in Samsung phones lies.

Furthermore, CSC is a component of SAMSUNG firmware binaries and it holds very important info for the device like:

  • Localizations and geo-specific info such as the system language, APN settings, and carrier-branding
  • Customized settings
  • System configurations

Here’s the thing, the same Samsung phone model in a country or region might have different CSCs depending on the fact whether the Samsung device is carrier-branded, unlocked, or locked.

To make this clearer, let’s see an example with a Samsung Galaxy device owned by a user in the United States. If you live in the United States and own a Samsung Galaxy phone, the CSC or product code of your device may be one of the following:

  • ATT – AT&T – This is a carrier-branded CSC code
  • CCT – Comcast – This is a carrier-branded CSC code
  • LRA – Bluegrass Cellular – This is a carrier-branded CSC code
  • SPR – Sprint (CDMA) – This is a carrier-branded CSC code
  • TFN – Tracfone – This is a carrier-branded CSC code
  • XAA – USA – This is (unbranded/unlocked/default) CSC code
  • XAS – USA – This is (unbranded/unlocked) CSC code
  • TMB – T-Mobile –This is a carrier-branded CSC code
  • USC – US Cellular –This is a carrier-branded CSC code
  • VMU – Virgin Mobile USA –This is a carrier-branded CSC code
  • VZW – Verizon – This is a carrier-branded CSC code
  • ACG – Nextech/C Spire – This is a carrier-branded CSC code

One very important area where CSC comes to play is for official software updates.

Samsung servers check on the CSC code of your Samsung device and match it with the geo-location where it’s being used. If the CSC code matches, OTA updates to your device will be shown if it’s available for your region.

Let’s say, the CSC code of your Samsung device is INS (India) and you take it to the United Kingdom or Germany and use it there, you may not receive the official software updates from Samsung.

Again, the CSC of a Samsung Galaxy phone firmware contains the code-name of the country/region for which it is built.

You can change your Samsung Galaxy phone’s CSC so Samsung servers would think your device is from a different country or region to receive official updates.

Similarly, if you flash the firmware meant for some other country on your device, you’ll not get any future updates unless you install the proper firmware.

How to Check or Find CSC on a Samsung Galaxy Phone

If you have a Samsung galaxy phone and would like to change the CSC of your device, first of all, you should know which CSC your device is fixed to.

Once you know the CSC on your Samsung phone, you will find it easy changing the CSC of your Samsung phone.

So, here’s how to know find/check the CSC of your Samsung GALAXY phone.

You can find/check the CSC of your Samsung phone by dialing *#1234# on your phone’s dialer app. As soon as you type the last # symbol, you’ll see a screen like in the second image below. Under CSC, the first 3 alphabets after your device model is the CSC code for your Samsung device.

In our case G950F OXM 9DTE1, OXM is the CSC.

  • Open your app drawer or view all installed apps
  • Click on Settings
  • Scroll down and tap on About Phone
  • Tap on Software information.
  • Scroll down to Service provider SW ver. The info in Service provider SW ver shows the region code or CSC of your Samsung phone. In the image below, it is OXM, it’s a Multi-CSC or Omni CSC with a total of 86 different CSCs to choose from. The INS refers to the region, India (country).
  • If your device is a carrier variant, you will also see the carrier’s code there.

Since I flashed the OXM (Multi-CSC) firmware and switched to INS (India) CSC, it shows me both the CSCs. In the 3rd line, you can see the activated CSC, which is INS. This simply means that I’ll keep getting official OTA updates.

How to change CSC on Samsung Galaxy phones

Now, let’s come to the 3rd line in the above image: (1)INS/(2)INS, INS/(3)INS and explain what it means.

  • The first CSC value, that is INS, shows the active CSC. This determines the access to services and software updates. You will receive updates on this channel. This is also the country used for Samsung’s Beta programs in case you want to join one.
  • The second value “INS,INS” shows that my Galaxy S9 is a dual-SIM variant. If you don’t use the second SIM slot, the second value replicates the first one. This value only shows what SIM you have inside, and doesn’t affect any aspect of the experience.
  • The 3rd CSC value, that is INS again, shows the country code for which the Samsung device has been manufactured and configured. This one cannot be changed and it doesn’t need to. In case you get the phone from a carrier, this value will have the locked CSC code. In case the other values don’t match, your carrier can refuse warranty service (since warranty goes through the carrier in case you’re on a contract)

Note: If you have flashed a Multi-CSC firmware, your device will automatically switch itself to the Country Specific Code based on your network provider on the first boot.

  2. I tried it today with M31s, Android 10, Baseband Version : M317FXXU2BTJ7,M317FXXU2BTJ7. The theme installed, but under legal the menu for the change doesn’t appear.

  3. Hi,

    I am using my Samsung phone which I bought in India and using it in Australia. I have tried the *#272*IMEI number* option, but I don’t have the Australian CSC option. How can I change the CSC to Australia?

  4. You need to make it functional with Android 11 and the newest security patch!

    I can make it function your application but Android 11 is not between it so I can’t do anything with and my android version is past bin 5 so I can’t downgrade!

    Please make it able to use for me as well!

    I have it already changed my csc to phe but the last one in the code is still connected to my provider and need to change that!

    bought was this: SAOMC_SM-988B_OXM_ATL_RRxxxx

    Now what I have changed already is this: SAOMC_SM-988B_OXM_PHE_RRxxxx

    So the last ATL needs to be changed to PHE as well!
