I read that you take a pit-file - why?
Did you take this firmware?

Where do you see your CSC?

Thank you for intrest in my problem.
Tutorial on polish forum said to take a .pit file and check repartition box - I followed instructions.
I see my CSC in Settings/Telephone - informations (I'm translating from polish it may be diferent named in english, it's last card on the bottom of Settings)/Firmware informations - there I can see CSC
About 10 minutes ago I have resolved the issue.
I have inserted different sim card (from my work) and CSC has changed to XEH/XEH/XEO/XEH.
Then I switch SIM to second slot and CSC become XEH/XEO/XEO/XEH.
Then I did factory reset and now I have XEO/XEO/XEO/XEH
Bottom line instaling new firmware doesn't automaticaly change CSC. You need to insert SIM card to one slot, then to second slot and then do factory reset.
I hope this could help others.
Edit:
Not every SIM card will change CSC. If you have trouble try different SIM card preferably from different operator.

This post was published over 4 year ago, and now I encounter this issue too!
My phone is SM-N960N, and I did flash the corresponding firmware with .pit for multiple times with original system unchanged (CSC code: KTC). What's more, I just got this phone last night!
Does the computer OS itself cause this issue? I promise that Samsung USB driver is well installed.

[Guide] Change Note 9 CSC Without Root - Easy Guide

I followed a guide by XDA User applepay from this link, but just wanted to try and simplify it because i found it pretty complicated to understand at first.
It would be worth reading that thread before this even if it doesn't make sense. Please also read this complete thread before you attempt it.
I have only followed the guide so i can't answer any questions to help. I am not responsible for any problems you run into. This is just a guide of what I did to get mine to work.
I was successful using my SM-N960F going from CSC XME to TEL.
I cannot confirm that this method will work on other models, but i don't see why not considering the guide was originally for a S9.
Make sure you select your exact model when downloading files and flashing files. Using other model firmware may brick your phone.
Backup your files! I used Smart Switch on windows. This method will wipe your phone in the process.
Use the original usb cable you got in the box and install the Samsung USB drivers if you haven't already.
I have confirmed on my device that OTA updates work fine after this procedure.
Please comment if you think there is a better way or there is an error in this guide.
Download your combination file from here
Download your new CSC firmware from here
Download Samsung Odin 3.13.1 from here
Download RealTerm from here
1. Open Odin.
Click AP and select your combination file.
Put your Note 9 into download mode by turning it off completely, then holding the volume down and bixby buttons while inserting the usb cable. Confirm that you want to enter download mode.
Click start in Odin.
Once this is complete, your phone should boot into the combination firmware and show your model number. Close Odin.
2. Open RealTerm and go to Port tab.
Set Baud to 230400 and Select Port to ssudmdm0000 or very similar name.
Click the change button.
Go to Send tab.
Enter "AT" and click Send ASCII.
If you get a response like
"+USB READY
BOOTING COMPLETED
AT"
or
"AT"
or
"OK"
or
"BOOTING COMPLETED
AT"
Proceed to the next number.
If you didn't get a response click +CR and send again.
If you get a response like "ERROR" proceed to the next number.
Still if you didn't get a response check your phone status and cable status.
If everything is normal proceed to the next number.
If still you didn't get a response it means your phone or cable is not normal status.
3. Enter "AT+PRECONFG=1,0" and click Send ASCII.
You will get this response.
AT+PRECONFIG=1,0+PRECONFG:1,???
OK
-??? is your current CSC.-
4. Enter "AT+PRECONFG=2,???" and click Send ASCII.
Enter ??? you want to change to another CSC.
You will get this response.
AT+PRECONFG=2,???+PRECONFG:2,OK
OK
-??? is your changed CSC.-
5. Enter "AT+PRECONFG=1,0" and click Send ASCII.
You will get this response.
AT+PRECONFIG=1,0+PRECONFG:1,???
OK
-??? is your changed, current CSC.-
6. CSC change is now complete. You can now close RealTerm.
7. Open Odin again.
Turn your phone off and then put it into download mode again by holding the volume down and Bixby buttons, then plugging the usb cable in.
Fill each field (BL, AP, CP and CSC) with their respective files from the firmware which has the new CSC.
Use the CSC file in the CSC field, not HOME_CSC.
Click start. This will now wipe your phone completely.
8. Your phone should boot into android and everything should be complete!
Enjoy using VoLTE, VoWiFi and RCS!

Many thanks! Will give it a go.

@laneyyy I guess this is for unrooted device right? There are much easier ways of doing it in rooted device

Yeah this is for unrooted devices

Hmm, will this allow my unrooted n960f/ds to flash the TMB CSC and work? Or does this just let you change to another CSC within the multi CSC?

Odin still won't let you flash firmware files from an other phone model. which is a good thing since csc.md5 contains a pit file that is very much phone model specific....you dont want that. home_csc.md5 dosent but regardless Odin should still throw an error. I wouldint be game to test with the prince Comey edition of Odin that allows you to do this forcefully apply wrong model firmware file. might work... or not

how about future OTAs after ? if I flashed TMO csc will I get all TMO OTAs in future ?

@laneyyy i need to select combinations file Odion in AP right ? I guess I have to downgrade my firmware first Odin don't let me flash I have the last one firmware

My phone was up to date before I used the latest combination file for my model on that site. I didn't get any errors about downgrading.
As far as OTAs, I'm not sure yet, but worst case is you just need to flash new firmwares by Odin. I think it's definitely worth the trade off to get volte, vowifi and RCS if that's the case

Iam able to receive calls and everything but cant use the phone since the error doesnt go away. Any help with that ?

try flashing with the latest odin csc_home.md5 corresponding to your sim cards CSC or region.
csc.md5 can also be flashed but might wipe data.

EDIT : I just found my phone's CSC from Sammobile.com if i flashed CSC do i have to flash to stock rom or the custom rom will work with that csc ?

just the csc.md5 or home_csc.md5 should work.
you can also download your firmware with sam firm tool 0.3.6 as well. should be much faster.
regarding csc, your sim card is from a carrier(phone company).
carriers have a 3 letter code that identify them. you can use that 3 letter code to search and install the csc file.

as always do a full twrp backup 1st.
flash home_csc.md5 = no data wipe
flash csc.md5 = possible data wioe/phone reset
also id take out the sim 1st, flash and make it boot to home screen. then shut down phone insert sim and then power up again.

Changing CSC on S10 without data wipe

Hello there,
I have bought phone that was from different distribution than my country, everything is fine except I don't get any updates. I'd like to change my CSC code from BTU to XEO but without wiping the phone and without tripping Knox. I have read that it is possible by flashing HOME_CSC file. I downloaded the latest samsung original firmware from Sammobile and got five files. I know i should flash HOME_CSC but I dont know if I should flash all the other ones. Can you help me with the process and share some tips? Thanks

This thread may help you if you care to read 30 pages worth of posts:
Now you can not change CSC code with firmware + SIM-card
I could easily change the CSC code on my Note9: just installed OXM firmware + factory reset with needed code SIM-card (Thailand for example). But this method does not work anymore. How to change a CSC code on S10?

[Guide] How to convert s10-g973N to sm-g973f, change csc from skc to koo or any another, fix emergency calls only. No need of paid apps, boxes etc.

**********This is first time am posting a guide so pardon me. *******
********As usual am not responsible for anything that happens to your phone.*******
*****Am not claiming ownership of the above technique, its what worked for me*****
I saw many posts here about people struggling to change csc from skc to koo or international***
Others had issue with their phone suddenly lost network and just displays emergency calls only****
so I have s10 sm-g973n which had csc as koo then flashed skc my mistake. The phone booted with annoying skc boot logo, and branded junk from the carrier. Then one morning the phone couldn't connect to gsm network!
I tried all manner of things to fix it. Rooted with magisk, flashed custom rom nothing.
Tried samkey to change csc still nothing. modified odin in flashing multi csc rom nothing.
Got some luck in changing csc by editing efs/imei/mps_code.dat using root explorer, text editor and vola the carrier junk disappeared. But still no network.
was told only way is to use z3x box or chimera to patch certificate but didn't give up. I posted question here in xda but no guide or response.
But that gave me an idea of what could be the issue- corrupt efs that needs the certificate to be patched. so got keyword.
After watching many YouTube videos I came across a video about a rom that has certificate patched. Just flash with odin and done!
I downloaded and followed the instructions. The phone booted up fine and after going through initial setup the network was back!
Not only did the network came back but the model changed to F, csc became oxm! You can now use tools like Samfw from too to change csc to your local region.
Later in the day, will be flashing firmware with my region csc.
Here is the link to the rom:

And here is the video:

Thanks for your post. I think before do it we need back up all anything

Yes sim 2 will work. And after completing flash stock rom for security reasons. Because the above rom is rooted and modified we don't know how secure it is. after network certificates are patched now flash a stock rom from eg sammobile or samfw etc.

When i flash this file the storage becomes 64gb

Did you find a fix for that? For me the internal memory become 32Gb. Is there a solution for that?

I bought an S10 that turned out to be a G973N(SKC) flashed to G973F-D/S(XSG). I think they used this method and these files to do it. I can't get the OEM unlock option to come up. I've tried everything. I am starting to think that it's because of the XSG country code. I was going to try to change it XEU (Great Britain) in SamFW but it just stalls and doesn't do anything. Any suggestions on what I can do here to change the country code? I need that OEM unlock option so I can degoogle it.

Hi guys,
I have I big problem with this rom man, each time I restart my phone i lost network and I have to reflash your rom and factory reset the phone to get it back. It's like it's forbidden to restart the phone, otherwise my network get lost and IMEI Status NG again.. Is there a fix for that? Thank you. Is there a for that fix?
Or do you guys have a rom based on android 12 for g973n u7 converted to dual sim that can solve this IMei STATUS NG? I watched on youtube some guys that have it but it's not free or I can't pay that from here in my cluntry the poorest country in the world.
Thank you guys.
