Hello I have a Problem with My CSC Code
When I Flash the DBT Firmware my CSC Code dont change its Always stand BTU
Hello everyone,
I thought of changing my mom's s7 edge region to BTU (currently KSA) as it is very slow in getting OTAs. It only got the December security patch update a week ago or so. As I am not familiar with Samsung phones, I read the forums for every info about CSCs (the CSC and home_CSC were very confusing). I checked the CSC using phone info and it does not have the original CSC, but have a lot of available CSCs and from what I read, I presume the ROM is multi CSC and that it comes with KSA because of the origin country.
But the problem is that I read somewhere that if you flash the firmware of some other region (eg BTU), you cannot go back to KSA, instead it will default to XSG, and also that you need root to select CSC. It also said 'maybe' I would be able to return to the original CSC using smart switch. Can anyone confirm this?
Will it be denied warranty or something when I cannot revert CSC back to KSA before giving it for warranty? (I read that changing region generally does not void warranty, but I think I'm paranoid **thinking of my mom screaming at me**)
Also if I flash the UAE firmware (XSG), will I still retain my own CSC if I do not flash the UAE CSC along with it because XSG is given is my available CSC codes? ( If that is true I should flash BL+AP+CP without CSC or am i wrong?)
Please pardon me if this was asked before but I could not find any information regarding the first and third question
Thank you very much!
I will try to explain muy question...
Im using a S8 Dual Sim (SM-G950FD) with XSG CSC (In Firmware section appears XSG/XSG/XSG like mi CSC code), but im from Mexico and recently I changed the firmware to another with TCE code, but when my phone starts, after the firmware change with the combination rom, my CSC code was something like this:
TCE/TCE/XSG
What means each one of these codes and why the last didnt change to TCE?

Good news for the people who wants to change CSC according to their home country.
Now, you can easily change your CSC no matter from which region you had bought your phone.
***No Root Needed***
Follow this steps to change CSC:
1. First insert the Sim of your desired CSC country.
2. Then after restarting just factory reset your phone.
3. Now the phone will boot up with welcome Screen.
4. After few seconds it will ask you whether you want to change the phone settings and region according to your Sim Card providers country.
5. Boom!!! now, phone will reset again and welcome screen will appear again. Now, you will have the same CSC and configuration according to your own country.
N.B: It works only for OXM Multi CSC based Firmware after One UI 2.5 update. So, every device with OXM MULTI CSC & One UI 2.5 update will be eligible.
Will it also change the SW-service provider, like from Vodafone to a unlocked sw-version?

If you are trying to change the CSC first ensure your firmware is based on OXM Multi CSC and your desired CSC is part of the OXM CSC family. Otherwise it won't work. And for checking correct CSC after following this procedure use *Phoone Info Sam** app from playstore

I have the OXM multi CSC. I will try that later.
Im trying to get back to ZTO since I changed my phone's to DBT.
For people who can't switch between csc in the same mult csc pack. OXM multi csc pack contains all the european generic and network branded firmware (csc) so if You are at SFR (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the SFR will stay. What you need to do is to flash it with different multi csc pack (just see what packs are available for your model), then flash it back with OXM multi pack, and it should switch to some generic csc, then if you instert your sim card it should ask you if you want to customize your phone to the inserted sim card and it will change your csc to the one you want.

Hi sivuha0101,
So if i undestand your solution, as i am from FRANCE ( XEF )
1- flash with a NZC firmware like it doesn'nt contain neither XEF or TIM ( mine actually )
like : SM-G986B_1_20210501192706_0r7rhuu316_fac.zip.enc4
( do i need to flash all ? ie AP,CSC,CP and BL ? )
reboot, fast install etc....
then
2 - flash again with my XEF rom :
SM-G986B_1_20210517170737_0n0cb625x6_fac.zip.enc4
and insert my sim card to detect my correct CSC code .
I am right ? thanks for this information btw !
EDIT :
tried, the flash failed with the NZC firmware ( the phone is good ) but now i don't know what rom to flash
Answering my self :
1/ buy Samkey credits on ebay user ( 5$ )
2/ Use one credit in Samkey software to change the CSC ( less than 2 min )
3/ Enjoy your phone !
