S8+ Change CSC for wifi calling - Samsung Galaxy S8+ Questions & Answers

Hello Everybody ,
Just received an S8+ bought from Amazon.it
I placed my Cosmote Greek SIM before turning the phone on for first time.
The phone has OXM multi CSC firmware installed but for my bad luck , the COS CSC code for my network (Cosmote) is not listed.
Current active CSC code according to phone info app is EUR.
I need to install the ODX multi CSC code firmware which has the COS CSC file for Cosmote.
The reason for changing the CSC from EUR to COS is to enable wifi calling supported from Cosmote network.
Is there any guide to do it without involving root?
Thank you.

Perhaps this thread will help you. https://forum.xda-developers.com/galaxy-s8+/development/utility-flashable-csc-selection-v1-0-0-t3605264

Thanks for your reply but it does not fit in my case.
I do not want to root my phone and the thread mentioned requires root access.

[Q] are csc files device-dependant?

Hi
I want to update my csc since I've done some stuff to my phone and changed it; now I don't have my original csc. I can't find a specific csc for my device (n900w8) and I'm wondering if it's OK to use a csc of my region even if it's not for my device.
Regards!

Changing the CSC from DBT to DTM

Hi @ all.
A few of German S6 users who own a T-Mobile contract are a little bit in trouble. Since T-Mobile has activated VoLTE it is only possible to use this feature with a branded S6.
So we tried a lot of things to change the CSC.
Flash the 4 parts firmware first then do factory reset and so one, but finally we get only DDE (this is Congstar without the possibility to activate VoLTE)
My idea.... is there someone who is able to modify the CSC and extract the DDE files so that we flash only DTM.
Thanks in advance.

Samsung S8+ CSC change on Exynos F model

Hello,
I have been trying to find an answer to my question or a solution but all the results I found on XDA are Snapdragon model oriented.
My question is about changing the CSC just to be able to receive OTA updates faster ( I don't want Samsung Pay ..) . I aleady know that the product code is hardcoded into the phone I just need to change last three letters of the CSC.
My rom is part of the OXM multi-CSC rom, I flashed it and tried the famous code to change the CSC region but no results so far. I also do not have any other sim card to trick the phone after factory reset.
Could anyone please help ? has anyone been able to change CSC via odin ?
Regards.
Can anyone help please ? is my question a little bit confusing ?

Changing CSCs isn't possible without root or without a local SIM card from the country whose CSC you want to use.
If you're so eager to get faster updates, just flash them with HOME_CSC_OXM as they are released, you won't lose your data and you'll be on the latest OXM builds as well.

CSC Changing Help

I have the G955FD on the BRI (Taiwan) firmware. I live in Australia, and really want to use Samsung pay. How should I change my CSC from BRI to XSA? I've seen varying information here and on other sites. I want to keep my Google Play as Certified, still have OTAs and without tripping KNOX. Essentially like a standard phone from this region. I don't particularly care about Dual-SIM, but it'd be nice to still have.
Here is my current software information: imgur(dot)com/a/197z5 <-- I can't post links yet, remove this if not allowed.
Thanks for helping

Hi mate
Without root there are not many options ..
First F and FD firmwares are compatibles ( same device!! exynos to exynos) , you can flash an F firmware into an FD or vice versa
you could try to change your CSC to your SIM card CSC first
Check here
On the thread it shows how to add your SIM CSC to your current CSC config , if it work you may end up with a configuration like BRI/BRI/XSA , in my case I got TPA/TPA/PCW , TPA was the software default and PCW sims CSC. I do not have Samsung pay so i do not know if that change will be enough to make it work. Back up you need to factory reset for this.
The other option is to flash a full XSA firmware ( use a G955F firmware) , read here how to do it
BACK UP before you do anything

Thank you very much! I'm now running XSA/XSA/XSA with a flash. Dual-SIM support is still there which surprised me. There were some issues with Odin, but I fixed them up after a while.

Great news mate!!
Firmware is 100% same for F and FD so you should not see any difference at all , I asume also you got Samsung Pay working.
Good job!
I did the same when I had s8+. flashed TEL (Telstra) SM-G955F firmware which I got off Sammobile and worked like a treat. Samsung pay, VoLTE, Wifi Calling, Spam detection in calls worked as well.
I upgraded to S9+ and tried to do the same. The flash process works fine but CSC doesn't change. I am stuck on AFG CSC. Apparently it cant be done on S9 as Samsung is imposing multi CSC format.
Well, you are lucky one to have S8+. Enjoy

That's unfortunate
I'm curious why you flashed TEL instead of XSA, XSA is the unlocked version and it still has WiFi calling, VoLTE etc. I have an ALDImobile SIM (which uses Telstra) but I installed the unlocked version to have minimal bloatware and the stock boot logo.

I tried both. First preference is always XSA but I tried TEL in anticipation that it may work

Multi CSC FILES

Hello All.
I recently made the huge mistake of factory resetting my Samsung S10+ device and now it is locked to SK Telecom, Korea. I am just now realising my phone is a Korean make and all the available CSC files are korean.
1. Is it possible to flash a Custom/Multi CSC files onto my device and what is the process?
2. Right, my devices internet and cellular network doesn't work because it doesn't detect any sim card inserted. The Wifi works alright.
Please help
Download the firmware of your country CSC on Frija and flash it ?
Or it is blocked too ?
