All Samsung Galaxy Series firmwares have three components that are as follows:
The name of a firmware contains all these details. Thus, PDA refers to the build version of the software/firmware, Phone refers to the baseband/modem version, and CSC (Consumer Software Customization) denotes to a specific geographical region or carrier. The CSC code contains the info about software packages specific to a particular region, carrier branding and also APN (Access Point Name) settings for data connection.
In this way, unless the PDA, PHONE and CSC codes do not match correctly, you will not be able to update your device over Samsung Kies or via OTA.
Now remember that the product code and firmware version differs from one device to another according to the region or country where it is sold. In most cases you can find out the country or region of a device for which it has been made by referring to the firmware version.
In the above screenshot, for example, look at the Baseband version that is: I9300XXALE8. Here is an analysis of the baseband version of the Galaxy S3, for example:
Again, as the CSC of a Samsung Galaxy phone firmware contains the code-name of the country/region for which it is build, you can change it to tell Samsung servers that your phone is actually from a different country/region and get official updates for that country. It often happens that a firmware update is released for a particular country and you do not get it in your country. You grab the firmware file but are afraid that you will not be able to get the future official updates on your Android device if you flash a firmware that is not meant for your country.
The idea of changing the CSC of you phone drops in here. Thus you can install a firmware from a different region and change the CSC of your phone with a little trick and everything goes fine.
Please note that performing the CSC change action will factory reset your phone. It means it will take your phone to the status as it was when you bought it. All data present on the internal storage will be wiped. Therefore, do not forget to backup you data before you proceed.
If the above set of code *#272*Phone’s IMEI Here# did not work for you, try the CSC Changer app developed by bassie1995. I have tested it on my Galaxy S4 and it works like a charm. But unlike the above method it requires root access on your Samsung Galaxy device. You can later unroot your device by choosing “Full Unroot” option present under SuperSU Settings and then by flashing the stock Kernel.
Warning: Whatever method you chose to change CSC on your Galaxy phone or tablet, it is sure to wipe all data and apps present on the internal SD Card of your device. So act wisely and backup all data first.
While this trick works fine with Samsung Galaxy devices with Android 4.0.4, some users have reported it not working having upgraded to Jelly Bean firmware. In that case, follow the following steps and then try the above trick:
If you do not want to go through this method, there is still another way you can change the CSC of your phone. Download a free app called Samsung Galaxy S / S2 / S3 CSC from the Google Play Store and install it. Run the app, follow the on-screen hints and done!
In case this app does not work for on unrooted device, root your phone first and then try again.
