Please note that I held no responsibility if you damage your phone, brick it or anything! This was made based on my own experience.

Hi, just thought I share my experience in changing CSC code. Initially I purchased my S5 with XSE (Indonesian) CSC code. Not having the patient for lollipop, I flashed Kazakhastan ROM and my CSC code changed to SKZ. After several months, samsung decided to release lollipop for XSE region and I flashed to it but was stuck with XXV (Vietnam). Not sure what happened but it seems that it takes the first code in the multi-CSC rom. Anyway this had me frustrated for a couple of months. So without further ado, here is the steps:
1. Download requirements:
-Download the BOC3 indian ROM: G900HXXU1BOC3_G900HODD1BOC3_G900HXXU1BOAD_HOME.tar .md5 (must be this ROM - this rom allows change CSC code without root)
-Download your country ROM (for my example is G900HXXU1BOD3_G900HOLB1BOD1_G900HXXU1BOCA_HOME.tar .md5)
-Download and install Cygwin - or any app which can modify .tar files, but lets use Cygwin for this case
-Download and install Odin 3.09 or higher (to flash ROMs)
2. Flash the indian ROM (G900HXXU1BOC3_G900HODD1BOC3_G900HXXU1BOAD_HOME.ta r.md5) to your device
3. While waiting for the ROM to flash, open your country rom, remove .md5 at the end so the name will be from G900HXXU1BOD3_G900HOLB1BOD1_G900HXXU1BOCA_HOME.tar .md5 to G900HXXU1BOD3_G900HOLB1BOD1_G900HXXU1BOCA_HOME.tar
4. Open the G900HXXU1BOD3_G900HOLB1BOD1_G900HXXU1BOCA_HOME.tar with winzip or winrar, extract cache.img and hidder.img and place in home folder of Cygwin
5. Open cygwin and type the following:
tar -H ustar -cf csc.tar cache.img hidden.img
6. Test the indian rom, open dialer and type *#272*your-imei-number# - a selection of CSC should appear meaning that the ROM can change CSC without root
7. Flash in Odin, put the csc.tar in CSC and flash - this will not trip knox - I have tried this myself
8. Boot your phone, open dialer and type *#272*your-imei-number# - from here more codes should appear including the ones included in the csc.tar file
9. Select your country code (in this case I selected XSE) and it will automatically reboot
10. Shut down and check your CSC in bootloader (hold power + up + home) it should be correct now
11. Flash your country rom, clear cache and everything and voila!

Please also note that this guide should work on other devices as long as the device has a rom with *#272*your-imei-number# enabled without root

Hope this helps!
