How To Change the CSC Code on Samsung Galaxy S5

Changing the CSC code of Samsung Galaxy S5 is very important on some part, one important benefit to this is so it can receive the latest software update which is officially rolled out by Samsung. This is basically useful like if you just bought your Galaxy S5 from an online store or just sent to you as a gift without knowing the default firmware of the phone to where and what country it came from. Samsung was using an special CSC file included in Android firmware which are specifically built and designates to each country or mobile network providers.

Now, once and every while when the new software update arrives, it will check the default software build of your device. Yes it's smart indeed, it will check your phone if still runs on official firmware or not. A software update will not allows you to download if it finds-out that your phone has been rooted or modified, this error message oftentimes appears "Your device have been modified, Software updates are not available" or "Your device have been modified, This device is not supported by Kies". But sometimes even if you did not do anything or altered your phone by means of rooting, custom recovery and custom ROMs or any other modification you still having trouble getting the latest software update.

This can be easily achieved when you try to perform a software update using Kies for it also checks the default AP or PDA, CP or PHONE, and the CSC file of your phone. It will only allows you to download if the new software update match the default firmware to that particular country or network operators. If the PDA, PHONE and CSC codes did not match correctly, and if somehow you've see this message "Your device's current firmware version is not supported to update firmware via kies." Well, you should then suspects that the problem lies with your phone's current firmware build that has other country or carrier provider's default CSC file bundled with it.

Though there was this old method to simply change the CSC code of your phone like the secret-code *#272*IMEI# and or some sort to root your phone first then use an apps. Those method only worked on older Android versions but it will not tend to work anymore on the latest Android 4.4.2 KitKat OS which is what your Galaxy S5 OS running right now.

To gain the official software update you must change the CSC code of your Galaxy S5 according to your country and or mobile operators (look for the SIM-Card you've been using). If you want to confirm if your phone does not have the default CSC file according to your origin, you can simply check it on your phone's software info by dialing *#1234# or do this;
1. From Menu tap Apps
2. Scroll to and touch Settings>
3. Tap More.
4. Scroll to and touch About device.
5. On this screen you'll see the Android version and current Software version of the device are displayed.
6. Tap More info

Here are the set examples of Software version which you can see also find the CSC version.

Build number: KOT49H.G900FXXU1ANCE

The highlighted three letters after the model number signifies the country or carrier product code or the consumer specification code or customer sales code.
