Changing CSC - Samsung Galaxy Note 8 Questions and Answers

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 !!!!

Firmware change from Branded to Unbranded

Hey guys,
i've got the G800F branded by T-Mobile.
PDA G800FXXU1ANL2
CSC G800FDTM1ANL1
I would like to flash the unbranded DBT version.
PDA G800FXXU1ANL1
CSC G800FDBT1ANJ1
since i dont want to trip the knox counter i've read that flashing the same firmware wont trigger it. the last letter in the PDA / CSC code is for the version right? since the last letter in the CSC from the DBT version is "J" which is before the "L" would flashing the DBT version trigger my knox?
greetings and thx

You won't trip the knox since it is stock Don't worry about anything. Just flash it via odin in PDA/AP section and don't forget to wipe data and cache after installing

eur/eur/dtm the last CSC will never change as this is hardcoded in the phone firmware.
If the first two are EUR/EUR then you have the correct CSC for OPEN Greece firmware.

Help needed with new phone.

So I just bought my Note 9 and have been away from Samsung for a while so I'm not really up-to-date. I have the N960F DS model with COS (COSMOTE Greece) CSC still on Android 8.1.0
How can I change my CSC and flash the latest EUR CSC (Greek CSC) Android 9 update?

If I flash the EUR CSC ROM through Odin even though I'm on the COS CSC, is KNOX going to be tripped?
Official firmware, no tripping of Knox

What about updates? If I flash it and perform a full flash, am I going to continue receiving updates under EUR OTA?

Sorry you can't anymore because the bootloader version (bl ver.) "7" in N950FXXS"7"DSG1 won't allow you to downgrade to a lower bl ver 6 or lower.
You now have to wait for firmware N950FTIM6DSF3 to get patched with July security patch from Samsung. Also since Germany DBT is the first firmware and Italy the 2nd july patch firmware you'll have to wait for others to catch up.
If you have any issues BACKUP your phone and do a factory reset!.

If you are on N950FTIM6DSF3 TIM (Italy) and want to keep data intact you'll have to wait for TIM to get updated, but if you want to be on the latest firmware from Germany DBT N950FOXM7DSG1 then you'll have to convert your N950FTIM6DSF3 csc to a multi-CSC OXM N950FOXM7DSG1 firmware which may or may not will erase your data.
You'll might have to flash the combination firmware to change the csc from TIM/TIM/TIM to DBT/DBT/(DBT or TIM not sure if this can be changed.) (BACKUP first this will delete data!)
The multi-CSC OXM doesn't support the TIM csc but it does support ITV csc (Italy). Before changing make sure you will not lose any Carrier specific features (etc. VoLTE, VoWIFI, .....) that you use.
Search for "how to change csc with a combination file" in google for more information.

use your last valid twrp backup from before the issue to restore:
carrier configs (odm)
efs
also when you flash full stock, use csc.md5 and not home_csc.md5 as CSC file.
it migh be good to research what the very latest firmware files are for your device. there should be a july update somewhere. so use that and try again.
if you want and try to fix ure csc issue try to flash zip in:

beware that you flash this at tour own free will and i cant be held responsible for anything.
do a full backup first.
in aroma choose DBT and choose ure correct CSC code.
