Changing CSC

Hello guys,
I recently bought a Note8 on Internet and I received it this monday. Besides being really happy with it I noticed that no OTAs were available.
I took a look at settings and I saw under carrier version there is "XEF/XEF/XSG", which could imply that the seller has flashed a XEF Oreo ROM before sending the device and with the system infos being incoherent, this is why I can't get any new updates.
So this is my goal : I want to be on full XEF CSC so I can enjoy VoLTE, VoWiFi and receive the latest updates, by this I mean having "XEF/XEF/XEF"
Here is my actual version :
AP : N950FXXU3CRC1
CP : N950FXXU3CRB9
CSC : N950FOXM3CRC1
Model : SM-N950F/DS
And obviously the Oreo ROM associated with XEF is :
AP : N950FXXU3CRC1
CP : N950FXXU3CRB9
CSC : N950FOXM3CRC4
Thanks for taking the time to read this and answer!!
EDIT : So my problem has been fixed

I assume the model you have is the Snapdragon variant, not the N950F.
If so, I don't see any reason why it should not work once you ODIN to the XEF stock ROM

Hello and thanks for answering.
You're assuming it wrong no offense. I have the N950F/DS model (implying I have the Exynos 8895)
If I flash the XEF 8.0.0 I have with Odin, will my CSC match with the rest of the firmware ?

Yes, as long as you use ODIN to flash a complete ROM, then your CSC will match unless you manually selected another CSC.
I thought VoLTE was limited to US carriers.

Last question, sorry to bother, the last time I changed CSCs my Samsung had Knox already tripped, I have actually the XSG CSC, if I flash with Odin the same XEF ROM I have now, will I have XEF ?

It is my belief that Knox is also tripped when when one flashes different CSCs from the base firmware that is selected during the flashing process. I don't think you will trip Knox if it is a full XEF ROM (unmodified) by Samsung.
I think it is something like a failed checksum (not signed by Samsung) that really trips the Knox flag.

Alright, thank you very much, I'll try flashing the XEF ROM tomorrow and I'll see if there are changes

As long as you flash OFFICIAL firmware, KNOX won't be tripped!
This is the latest FW for CSC XEF:
Model SM-N950F
Model name Galaxy Note8
Country
Version Android 8.0.0
Changelist 13688770
Build date Thu, 14 Jun 2018 10:27:19 +0000
Security Patch Level 2018-06-01
Product code XEF
PDA N950FXXU3CRF4
CSC N950FOXM3CRF4
Your device will stay "XEF/XEF/XSG": you CAN'T change XSG to XEF (that's the Production-code of your device)
Your ACTIVE & SIM CSC is correct -> XEF!

So this means I can safely download the latest firmware to update my phone (since no OTAs are available) and update it. Which CSC file should I use ? There are two available (CSC_ and HOME_CSC). If I remember right the second allows me to keep my data right ?

Hello again,
A completely random question, if I flash a carrier ROM (with FTM CSC), will I have the carrier ROM, will I have "FTM/FTM/FTM" and will KNOX be tripped ?
Sorry for bothering

As I already answered earlier: when flashing OFFICIAL firmware, KNOX will NOT be tripped!
The last CSC will NEVER changed (Product-code): in your case it will stay XSG
FTM is also in a Multi-CSC, so I don't know if it will change to FTM/FTM/XSG
Why not stay with your UN-branded XEF/XEF/XSG?

Hello again!!
Well indeed I forgot that. Okay so now I know I won't be able to change the product code, I was wondering if when flashing a firmware that didn't contain the XSG CSC (my SIM card would apply the FTM) things would change.
And FTM is my carrier so I wanted to try all the features reserved to Orange's ROM
But thanks again for everything sir!!!

Quick updates on this story
Hello guys !!!
Here are some quick updates about my situation. I followed @henklbr indications to update manually my phone to one of the latest firmwares, I do still have "XEF/XEF/XSG" but it doesn't matter because my main complain was that I wasn't getting OTA updates.
This behaviour has been changed now that I'm downloading an OTA update to get the latest firmware and possibly the future ones.
I will mention all the people who helped me :

Thanks again for all guys and long live the Note8 !!!!

What did I do wrong trying to change my CSC?

I received my international version of the N960F/DS. It had XEU firmware. I tried to install BTU firmware via Odin using a SamFirm BTU download and a UK Giffgaff SIM and selecting CSC, not Home_CSC. I still ended up with XEU.
1st question - am I likely to get Pie and other updates more quickly on BTU than XEU?
2nd question - how do I change from XEU to BTU? I think I saw that on previous Galaxies maybe you had to install a firmware not on the OXM multi CSC and then install BTU afterwards. Is that what I should have done? If so, what CSC do you suggest?
3rd question - should I just leave it alone?
TIA.

simply flash desired firmware wont work, you will need to flash combination file first before that.
follow above comment will work

Change CSC within multi-CSC

HI everyone,
I have a G970F/DS that has come with XSG firmware and I am trying to change the firmware to XSA
According to the image here https://forum.xda-developers.com/galaxy-s10/how-to/g973f-g973n-multi-csc-firmware-t3903050
For OXM multi CSC
SM-G970FXXU1ASAT-G970FOXM1ASAT
SM-G970FXXU1ASBA-G970FOXM1ASBA
The XSG is in the OXM multi CSC and XSA is in the single - I do not know what this means exactly.
I have tried
Using the *#272*IMEI# code with both IMEI codes, but i do not get a menu after typing it in
Flashing with new firmware from http://updato.com/ with Odin with the sim card in and out
Formatting the device using recovery mode with the sim in and also out+putting it in after
Using Odin to flash VD2 firmware and then back to the OXM firmware
When I flashed VD2 I got VD2/VD2,VD2/XSG in the software information but this went back to XSG/XSG ,XSG /XSG after flashing the OXM firmware
The sim card I am using is an Australian one from Optus and Odin is 3.13.1
Nothing seems to change to XSA.
Am I doing something wrong or is there something else I need to do?
Thanks

You can try inserting a Singapore SIM to see if it triggers Late Customization prompt to reset phone to XSP. 272 menu works in XSP

I don't have a Singapore Sim but I will see if I can get one to try with.
Do I need to reset the phone with the sim in or will the phone ask me when I put the sim in if I want to reset it?
Which IMEI is best to use with 272, does it make a difference?
Thanks for the suggestion

It should prompt you, but you can also try resetting in the recovery menu. I have always used IMEI 1 with 272

Worked for me!!!

WORKED PERFECTLY on my S10!!!
Changed CSC code from ZTO (Brazil retail) to ZVV (Vivo) after flash CHT firmware (from Chile).
I don't know why, but 4g+ from my operator (Oi - Brazil) doesn't work on ZTO -- br retail (it gets only 4g), but in CHT/ZVV it works 4g+ flawlessly!!! Despite Vivo's logo, I'm so happy!

Once you flash a Multi-CSC and your active SIM is within the said list then it would restart and make the changes.
So if you want to move to a different CSC then just use a different SIM that has the specific you need.

Hey just wanted to understand if this affects warranty. Also if you can post step by step guide on how to do this with samkey?

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 MEO (part of OXM multi pack), and flash it with TPH (part of OXM multi pack) the MEO 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), try to flash Brazil csc ZTO, it's part of multi pack OWO. 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.

Hello.
In my own case, I bought the SM-G998B from Korea, which is KOO/KOO/KOO, and I live in Africa. I won't mind being able to flash on OXM or any other multi-csc firmware, just so long as I can use my sim card here.
All I'm getting right now is limited service, and the option to select network operators is completely missing from my phone.

my s21U original comes with XSP CSC and firmware.. i have tried flashing to XME the flashing is ok and everything except that under software provider it still shows XSP... will it affect me receiving ota from XME?

Question Return to original firmware

Hi, Is it possible to return to original csc after flashing another official rom? because before I had XSG/XSG,XSG/XSG/XSG NOW I HAVE EUX/EUX.EUX/XSG ! I want to return to original firmware XSG/XSG,XSG/XSG/XSG thanks
