CSC "Problem" after Nougat update (A5 2017)

hi guys, i first installed the russian Nougat update because in germany (DBT) it wasnt out like 2 weeks ago.
So now it's out and i flashed the original german one over it with wiping everything. So far so good. The problem that i have now is that my orginal CSC "DBT" isn't activated.... it automatically installed the "BTU" CSC (UK)
My question now: How can i change back to DBT? I flashed the german CSC again but i doesn't seem to work that way :/ I added some screenshots from Samsung Phone Info App. The Original CSC-Code line is also blank whyever....
thx in advance!

https://forum.xda-developers.com/showpost.php?p=43553707&postcount=14 if it doesn't work i have another method

the same thing with my phone (i have flashed an XEF )
but this csc is not important at all .....
-You have german language
-the playstore have the same apps
- you have the same samsung fonctions apps and parameters .
-the modem have the same European bands
.....

Yeah i flashed the Portuguese rom and somehow got the sloveanian csc. I tried using the method above for changing but it didnt work. It doesnt matter, its the same stuff anyway.

The other method is to flash a single CSC rom and after flash DBT CSC

Can you please tell me what is your Knox Warranty Void status after all that flashing? I'm concerned about warranty if I flash german firmware which doesn't have the same csc as mine.

Sorry for interuption, but i just want to confirm - you had French firmware and then you flashed Russian and then again went back to French and your original csc has changed during this but your warranty isnt void? Thank you very much.

S9 with an active PRT play CSC ( branded )

Hey Samsung Experts ! :laugh:
I'm a newbie to this CSC stuff But I'm used to flashing via odin and firmwares switching.
My question is like this : I live in Morocco and I have a Samsung S9 Exynos Sm-G960f ( dual Sim ) with an active PRT csc ( poland and I guess it is branded ) when I first got the phone a month ago I got october security patch OTA and installed it. Now my phone says it is up to date ; yet , it is stuck at october security patch. Is it a CSC related problem or poland users hadn't received any OTA ever since october ?
I want to update my phone to Pie but I don't know which firmware to use.
I downloaded the newer ISREALI one with january security patch and ILO csc.
I'm intending to flash it. And if I flash csc instead of Home_csc will my phone work normally ? I mean no IMEI or network related problems ? and will My PRT CSC be replaced with ILO ?
I have read about combination files method but it is way complicated.
thank you.

Could somebody here possibly help me out with this ?
I will be thankful , buds.

how to Update using ODIN

Hello
i don't know if this question was asked before i tried to search but nothing
i came from xperia xz and flashing was just as easy as downloading the FTF and flashing in flash mod
i bought my S9 that was stuck at 1 Dec 2018 software and no new updates are available (even with smart switch) to download so my best solution is to update it manually using ODIN
i used to have a galaxy gear watch and s5 and flashing was also simple but i came across a thread that said something about CSC Version and i am sacred that i may brick the phone while trying to update it
can someone point me in the right directions ?
my CSC : G960FOXM2CRLI
Service provider SW ver.
SAOMC_SM-G960F_OXM_KSA_PP_0002
KSA/EGY, EGY/XSG
baseband version
G960FXXU2CRLI
build number
PPR1.180610.011.G960FXXU2CRLI
and i live in egypt but the phone was sold is KSA if that's matters
any help please ?
thanks in advance

If there are no updated KSA firmwares for your S9, flash any CSC for the G960F, Germany (DBT ) has the latest June update

If you have KSA sim card need to flash KSA firmware with only Home CSC also and if you have EGY sim card and will come OTA downloads
KSA/KSA,KSA/XSG

Well yes you need CSCs to match for OTA, but it is not necessary for normal usage, once my region releases the latest update I will flash back for OTA

so it's normal to flaash any firmware even if the CSC doesn't match? only the phone model number right? flashing on ODIN like thr normal way kust like the s5? nothing else need to be done ? like enabling/disabling stuff on developper options ? OEM unlock? sorry for my noobies questions

Normal if your own region CSC has not updated their firmware yes, but you will not receive OTA updates until the CSCs match and will have to flash manually each update
There is a big thread about it so I'm not going to go into it in detail here, quick search should find what you need
Nothing else needed, boot to download mode and flash with Odin 3.13.1

Thank you

No way to debrand?

I've tried to debrand my phone by flashing open market firmware (XEO, Poland). I downloaded the newest version of Odin, flashed it but now my CSC under settings says OPV/OPV, OPV/EUX/OPV. OPV is my carrier's CSC, I'm wondering what that EUX is. I've looked it up on Google and it seems like I'm not alone, seems like Samsung changed something and older methods no longer work. The question is - will I still receive updates released for my carrier or I'm screwed for good? Phone INFO app says my active CSC is OPV. I'm running S20+ 5G (G986B) Exynos variant.

Same problem here, I've flashed it with XEO POLAND G986BXXU1ATBM firmware using Odin3 v3.14.1_3B_PatcheD, few minutes later it showed "PASS" and nothing changed. Same branded firmware after reboot..

It seems, that many more 'branded' CSCs are now part of Multi-CSC. For me, this is DTM (T-Mobile DE). It osed to not be part of multi-CSC but it is now part of OXM.
This means, that you can not force it anymore, as you already ARE having the exact same firmware with the 'branded' CSC. Just checked, OPV is in deed part of OXM now.
In the Ultra Section is a thread showing the CSCs belonging to OXM: https://forum.xda-developers.com/ga...galaxy-s20-ultra-g988b-firmwares-5g-t4060443/
I have not yet found out / gotten an answer from anybody how to change CSC. Samkey also is not supporting the S20 series ATM - dont know, if this will change.

What I have worked out is that when you flash a multi-CSC firmware file you end running the CSC one letter earlier in the alphabet out of the. Available multi-CSC list
E.g. I had a VOD branded S105G and flashed BTU firmware, and ended up with TEL CSC
I also tried flashing BTU on an H3G branded A70 and ended up with EVF CSC
The original branded product CSC also never changes

Enable Developer mode and set OEM Unlock to ON before trying to change CSC via ODIN Flash

This should not be necessary? Doesn't that trip Knox, despite original Samsung Firmware?

Since now it's part of Multi CSC, does that mean I will receive updates faster? I can see other polish carrier's CSC are listed as single so I assume they are kind of separate firmware, am I right?

Honestly I do not know, if the respective CSC will be getting OTAs at the same time.
However, you can always flash manually with HOME_CSC, that is true.

Enable OEM unlock does not trip Knox. As long as you flash official Samsung firmware files in Odin Knox is never tripped
My own personal experience on S10 and above is you cannot flash a different CSC with OEM Unlock disabled
(Flash completes successfully but CSC doesn't change)

When changing from one e.g. branded csc to multi csc with the S10+, this worked fine without enabling oem unlock. Well, anyway. Flashing OXM multi CSC over OXM multi CSC will not change anything, right?

I found that you have to be on a single CSC before flash to multi-CSC and also you don't always end up on the CSC you expected
e.g. Flash BTU on a VOD product and you end up on TEL CSC (one letter in alphabet below VOD) and not on BTU

did everyone succesed DEBRAND ?
i v got s20 ultra OPV(orange) and need XEO (official)

Noob question: Can Odin change my German branded SM-G988B/DS to Nordic firmware?

Hello,
I am completely new to changing firmware using Odin, and I want to make sure, that I don't brick my phone
I have bought a S20 Ultra 512GB 5GB DS (Exynos), but it seems to be a German firmware, as it comes with Deutche Telekom apps preinstalled, two of which can't be uninstalled, and Samsung Members speak German instead of Danish.
My biggest issue, though, is that the latest OTA security update is May 1st.
Base band version: G988BXXU2ATE3
SAOMC_SM-G988B_OXM_DTM_QQ_0006
I found this: (can't post links on XDA yet):
samfw -> firmware- > SM-G988B -> NEE -> G988BXXU2ATF5
Which is for the scandinavian countries. (Nordic)
Changelist 18862671
Build date Mon, 08 Jun 2020 06:59:35 +0000
Security Patch Level 2020-06-01
Product code NEE
PDA G988BXXU2ATF5
CSC G988BOXM2ATF5
The questions:
Can I apply that to my phone, or will it brick the phone?
Will it get regular OTA updates for the nordic variant afterwards?
How much user data will be retained after firmware update?
Thank you so much for your assistance to a complete newbie

If you want to change it you will need to use Samkey (paid).

Oh, okay
That's another new thing for me to get into...
I will read up on it and get back with more questions
But can I ask already:
Which of these procedures (samkey and Odin), if any, will break warranty?

Hi again,
Sorry to be of bother...
I succesfully switched the CSC of the OXM firmware from DTM to NEE.
Now Service Provider Software Version is: SAOMC_SM-G988B_OXM_NEE_QQ0009
NEE/NEE,NEE/EUX/DTM
I know for sure, that the NEE models (though 128GB version) has received the One UI 3/Android 11 update.
But it is not offered as an OTA update to me.
I have rebooted twice, but still no OTA update.
I'm still stuck at an update from September/October.
Is it because mine is a 512GB version of S20 Ultra, while the rest of the NEE versions are 128GB?
Or is it because it still reads DTM at the end of ...NEE/EUX/DTM?
