S8 multi CSC Firmware question - Samsung Galaxy S8 Questions and Answers

Hello,
Can someone please try to explain this to me:
When I flash a multi CSC firmware on my S8, from the same region as my original firmware, how will the phone decide with CSC to assign from the multi-CSC list?
Example:
I have an S8 from Vodafone Romania and I want to flash the Romanian ROM firmware. But this firmware also contains other European unbranded CSC codes.
On what basis will the phone assign ROM as CSC to my phone? Based on the SIM card?
Many thanks.

No matter.
I have reflashed my branded Vodafone S8 with the open firmware for Romania. After, did a wipe cache and factory. Then the phone asked me to accept another reset to apply features from my sim card. Done that and the CSC is now the one from my country ROM. So, short answer, keep the sim card you want the CSC for in the phone to have specific settings

CSC change ?

Hi, i can't change my CSC with *#272*imei#
I bought my phone in germany, and flash belgium Firmware (which is the country i live) but the CSC changed from DBT (Germany) to SEB (Baltic) how
bump
Usually to change the CSC you have to flash the new firmware (which you have done) but then also flash to change the CSC. - On previous Samsung's (Note 3) - you have to flash the firmware, wipe the device then insert your SIM and it changes to your region.
This *may* apply to the S5 also, but only way to actually tell would be to do it, extract the CSC info and flash it. If you're unsure how to do this, then I'd hold off for a little while until others have tested different methods or release a guide on how to change it.

[Q][I9505] CSC changed itself

hi guys. anyone experienced the same. here's what happened:
i was using i9505 glb kitkat (csc=glb=globe philippines). i flashed clockworkmod, then install carbon rom.
last month, i re-flash my original glb kitkat. then went to recovery. i noticed that the csc changed to sin (singapore singtel) without doing anything.
now my problem is what rom should i use next time i update to lollipop: glb or sin.
pls help and many thanks.
Is your phone SIM unlocked? If it is, it doesn't matter which CSC you use. Otherwise, stay with CSC GLB.
No. I used regionlockaway to make it sim unlocked.
Then as mentioned, the CSC doesn't matter. Case in point is my I9505. Originally an O2 phone, when I purchased it the S4 was already unlocked and had Ukranian firmware on it. When I installed the Black Edition UK firmware (CSC BTU) after repairing my S4's SIM tray and again removing the SIM lock, I ended up with CSC AUT (Switzerland) instead.
On an open firmware such as CSC BTU, there are actually multiple CSCs within the firmware, and all the CSC does is customize the firmware to the needs of a specific region. In the case of AUT, the firmware installed three Swiss-specific apps that could be easily removed. BTU and the other CSCs essentially do the same thing, and I am guessing this is without modifying the firmware itself.
Ok. Thanks guys. I'll still use glb firmware once lollipop is released. I had once semi-bricked my s4 (got repaired at samsung center) so i'm kinda nervous this time.

[Q] Firmware download form different country??

ive seen other threads on this topic but none really answered properly.
I live in Ireland and bought my phone unlocked from the UK , i want to get my stock firmware back but i cant find one that suits my model and version. So would i
harm my device if i used a firmware from a different country that has the correct firmware i want????
s4 i9505
If the phone is unlocked you shouldn't have any issues. Except with CSC maybe.
whats CSC exactly?
Consumer Service Code, which is what Samsung uses to customize the firmware for a particular region. With devices that are locked to their carriers this also means the apps that the carrier wishes to add to the firmware. In your case, since your S4 is not locked to a carrier you can install any stock ROM you wish from any region. For example, my unlocked I9505 was originally on O2 in the UK (CSC O2U). When I purchased it from its original owner it came to me with Slovenian firmware (SI Mobil, CSC SIM). I subsequently flashed unbranded firmware onto the device and ended up with a device that thought it was Swiss (CSC AUT). In this last instance, three Swiss-specific apps were added that are not found in the other versions of the firmware. These apps were added because the CSC reported itself to the firmware installer and said, "install these apps as well". Had I changed the CSC to BTU I likely would have gotten some UK-specific firmware.

Sammobile wrong firmware! Please help

Hello,
Yesterday I downloaded the Vodafone Italian Nougat firmware, flashed it and immediately as my S7E turned on I saw that the firmware was wrong.
In fact the firmware is from Germany No Brand, I already downloaded it again just to make sure that I didn't made any mistakes, flashed it again and I have the same problem.
Sammobile take up to 10 days to respond, So I'm asking if anyone else has this problem, or maybe can anyone upload the real Vodafone Italia Nougat firmware:
Model SM-G935F
Model name Galaxy S7 edge
Country Italy (Vodafone)
Version Android 7
Changelist 10422490
Build date Mon, 20 Feb 2017 06:27:00 +0000

Product code OMN
PDA G935FXXU1DQBT
CSC G935FVFG1DQBT

Thanks, will download, flash and report back here
I downloaded that one myself some days ago and had no issues.
However, I am wondering why did you flash it if it was wrong. You can easily determine it by the filename.
Has your device been on OMN before?

Yes mine is branded Vodafone, but I had the UK Nougat flashed, now I saw that finnaly Italian Vodafone Nougat became available I donwloaded it to flash, but the guys from sammobile made an mistake, yes the firmware is Vodafone, but it's germany not italy
It contains actually several countries but all are Vodafone branded.
Did you have a Vodafone Italy SIM inside when booting up for the first time?

Yes ofcourse, I an prepaid Vodafone SIM installed. The phone was not bought under any contract with Vodafone
the firmware is multi csc files with Germany is the main CSC. we cannot do anything with it. The only way i know how to change the csc fully to your country is via Samsung Service Center or you need to root the device and do it with samsung phoneinfo apps. Root and you will loose samsung pay function/secure folder and any knox related software like shealth
Usually the CSC changes accordingly to the sim inserted. Only if there's no corresponding csc it takes the default one in multi csc roms.
Please download Phone INFO ★Samsung★ and posts screens here to see what's really going on.
Here's the screenshot

Flash your original marshmallow firmware using the CSC. It will factory reset your device
Flash the latest Nougat firmware using the HOME_CSC from your original firmware (can be the marshmallow one or if you have an Nougat one, use this). Don't use the nougat CSC file anymore.
Unfortunately without a Single CSC file you are not getting back to your original CSC and a single CSC has not been published for Vodafone Italy. In case of multi CSC the system uses the CSC already applied or in case of change (since you've BTU at the moment) the standard CSC which is VD2 (Vodafone Germany) in this case.
The only way to change that is with root.

I said using CSC meaning the firmware included all the stuff of your firmware.
Sent from my SM-G935F using XDA-Developers Legacy app
Unfortunately that won't help as there's no firmware which only includes Vodafone Italy. There's only one with several European Vodafone settings and if you flash that onto a device with non-Vodafone CSC such as BTU it used the standard CSC included which is Vodafone Germany. I thought first different, too, unfortunately there's no way without root (tested it by myself).
Rooting is out of picture, because I don't want to loose warranty.
I'll try to download and flash Vodafone Italy MM, then flash it, after I'll flash again the nougat with the old MM csc.
Edit: in this case I'll wait for a few weeks until Vodafone Italy will release the proper csc file.
Thanks

Samsung built in CSC changer for OXM Multi CSC Firmware (Need to be on One UI 2.5)

Good news for the people who wants to change CSC according to their home country.
Now, you can easily change your CSC no matter from which region you had bought your phone.
***No Root Needed***
Follow this steps to change CSC:
1. First insert the Sim of your desired CSC country.
2. Then after restarting just factory reset your phone.
3. Now the phone will boot up with welcome Screen.
4. After few seconds it will ask you whether you want to change the phone settings and region according to your Sim Card providers country.
5. Boom!!! now, phone will reset again and welcome screen will appear again. Now, you will have the same CSC and configuration according to your own country.
N.B: It works only for OXM Multi CSC based Firmware after One UI 2.5 update. So, every device with OXM MULTI CSC & One UI 2.5 update will be eligible.
Will it also change the SW-service provider, like from Vodafone to a unlocked sw-version?

If you are trying to change the CSC first ensure your firmware is based on OXM Multi CSC and your desired CSC is part of the OXM CSC family. Otherwise it won't work. And for checking correct CSC after following this procedure use *Phoone Info Sam** app from playstore

I have the OXM multi CSC. I will try that later.
Im trying to get back to ZTO since I changed my phone's to DBT.
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 SFR (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the SFR 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), 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.

Hi sivuha0101,
So if i undestand your solution, as i am from FRANCE ( XEF )
1- flash with a NZC firmware like it doesn'nt contain neither XEF or TIM ( mine actually )
like : SM-G986B_1_20210501192706_0r7rhuu316_fac.zip.enc4
( do i need to flash all ? ie AP,CSC,CP and BL ? )
reboot, fast install etc....
then
2 - flash again with my XEF rom :
SM-G986B_1_20210517170737_0n0cb625x6_fac.zip.enc4
and insert my sim card to detect my correct CSC code .
I am right ? thanks for this information btw !
EDIT :
tried, the flash failed with the NZC firmware ( the phone is good ) but now i don't know what rom to flash
Answering my self :
1/ buy Samkey credits on ebay user ( 5$ )
2/ Use one credit in Samkey software to change the CSC ( less than 2 min )
3/ Enjoy your phone !
