[Q] Flashing stock ROM doesn't change operator CSC...

I just bought a I9305 from my french operator called SFR and I flashed it with the stock ROM. After Wiping Data from recovery mode, I managed to get rid of all the operator bloatware but, when I connect my phone to Kies, it still telles me my CSC is CSC:MA1(SFR). Is that normal? Or is there something extra I need to do to get rid of my operator's CSC? Is that even necessary?
Thanks.

Hi,
As I tell you on Phonandroid Forum , everything is right.
You just have to check your CSC code by enter
Code:
*#1234#
if you want to manage your CSC code* just enter
Code:
*#272*IMEI number#
check your CSC. You should be in NEE area.
Now you can change it in
XEF (for France - not sure existing yet for I9305)
*Take care: full reset ( factory reset ) your device if you change CSC

[Q] Question about Sammobile's firmwares?

So, my baseband version is I9305XXBLL5, and I'm on Portugal's Vodafone. I'm planning on rooting my phone so I can unlock it, but I gotta make sure I can return it to factory status (unrooted/locked) just in case I need to, for warranty purposes.
In SamMobile, there are 3 different firmwares with the same baseband version: one for Germany (Vodafone), one for Croatia (T-Mobile), and one for Switzerland (Swisscom).
Once I need to flash one of these to restore it to factory settings, can I just flash any, as long as they have the same baseband version? Or does it need to be the same carrier/country? If so, where can I find one for my carrier/country?

Baseband is nothing. What you need is a firmware with the correct CSC.

Where can I find my CSC? And also, after rooting and unlocking, wont I lose all the Vodafone apps? If so, if I flash a firmware with the same CSC (whatever that is) but different carrier, wont it come with that other carrier's apps?

CSC is the sales code three letters found on the box as the last three letters in the ART code and if I'm correct it should be TCL.
And the CSC contains the operator apps (normally in the hidden partition). So only if you change that ROM to another CSC you will lose operator apps.

Ohhh I see. Finally, someone that can explain things right to me.
Would it be too much to ask for you to help me backup the phone, root and unlock it? There are so many different ways, and some count for the flash counter or something like that, some don't, I don't know which one to use.
I just needed to SIM-unlock my phone, and know how to return it back to its original state if I need to, I don't want to install any custom ROMS or anything besides unlocking it. And I really needed it today

If you do a simple search you find all the answers right here. To unlock you need a 4.1.1 firmware but read here this does not need root afaik.

Because BTU & SER are both part of the Multi-CSC OXM, you can't change the CSC!
You can only change CSC to BTU/XEU if you insert a BRITISH SIM-card in your device...

You can change CSC using combination file.

I have changed mine from XEU/XEU/BTU to BTU/BTU/BTU using this.

Help changing CSC to INS for S8 G950F (PDA G950FXXS5DSF1)

Hello,
I`ve been reading here and asked questions related to changing the CSC of S8 G950F to INS or THL (India/Thailand)
Here:
https://forum.xda-developers.com/showpost.php?p=79846281&postcount=66
https://forum.xda-developers.com/showpost.php?p=79511812&postcount=127
But without luck, can someone guide me on what to do please?
Currently I have:
- PDA = G950FXXS5DSF1
- CSC=G950FOXM5DSF1
- OXM_ROM
- unrooted, unlocked, warranty not void
- exyno cpu
*I`ve attached some screens with what I have
I still did not understood all the steps from https://forum.xda-developers.com/galaxy-note-8/how-to/pie-call-recording-wip-t3905737
I`ve downloaded from sammobile G950FXXS5DSF1_G950FOXM5DSF1_ROM.zip file with what I have currently, the zip contains the files:
AP_G950FXXS5DSF1_CL16019454_QB24073188_REV00_user_ low_ship_meta_OS9.tar
BL_G950FXXS5DSF1_CL16019454_QB24073188_REV00_user_ low_ship.tar
CP_G950FXXS5DSF1_CP12892158_CL16019454_QB24073188_ REV00_user_low_ship.tar
CSC_OXM_G950FOXM5DSF1_CL16019454_QB24073188_REV00_ user_low_ship.tar
HOME_CSC_OXM_G950FOXM5DSF1_CL16019454_QB24073188_R EV00_user_low_ship.tar
What I do not find is combination files for this PDA, on this link https://www.hardreset.info/articles/samsung-combination-firmware/ I can only see U4 bootloader version and I am not able to find anywhere on the internet the latest combination of files, can I generate this by myself so I can proceed to the change CSC step? Or what should be the solution?
What I found is https://forum.xda-developers.com/galaxy-note-9/how-to/how-to-make-combination-file-samsung-t3861381 to create the combination files, but it does not help.
Also the step where I install the firmware after the CSC is changed. I am not able to find INS or THL version of my bootloader v5
What I found on for INS on:
https://www.sammobile.com
http://updato.com
G950FXXS4CRLB_G950FOXM4CRL1_INS.zip
G950FXXU4CRL3_G950FOXM4CRL1_INS.zip
Not 100% sure if I should flash one of these as I see it has different bootloader..
Can I flash the G950FXXS5DSF1_G950FOXM5DSF1_ROM.zip back after the CSC change to INS and I should get an OTA update with android pie from india?
Thank you!

Anyone that can help me please?

Hello, thank you for the message.
It is the only method for me to buy the THL sim card? ( I`m asking because it takes 1 month to arrive )
I`ve read over the link you provided, and found a link related to how-to-change-csc-in-samsung-galaxy-phones/ ( I can not post the link here it seems XDA override the link )
I`ve checked I have the OXM firmware, so I`ve tried to use the dialing code for changing CSC:
==================
Open your phone’s dialer and type the following code with your device IMEI number: *#272*IMEI number# (replace the red text with your device’s IMEI number).
==================
But I get
"connection problem or invalid mmi code"
*also checked the preconfig.apk is not in /system/app/

Should I flash?
COMBINATION_FA70_G950FXXU4ARI1_CL12792727_QB19841686_REV00_user_mid_noship.tar.md5.zip
Or I can get bricked because I have U5 and the file is U4 bootloader..? In case of brick flashing stock firmware fixes the issues to get back to normal?
Or I should downgrade the bootloader from u5 to u4? if that is possible, and then flash the U4 found combination of files?
Any of this without tripping knox

I guess the only solution is with sim or wait if someone release combination of files with V5 bootloader version for my stock rom? and also maybe to have the stock INS for V5?

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?
