How to change firmware from csc SKC to KOO of same region (Korea)?

I tried to flash the firmware for KOO csc version on my S9, it says passed ang turned green, but on my phone, it restarts to recovery when the installing system update just began to happen.
Can anybody help me how will I be able to flash this firmware properly? I've been using ODIN for my previous samsung phones , flashing and modding, but I can't pass this one.
thank you very much in advance!
Model is SM-G960N
CSC version and PDA version are same for SKC and KOO
PDA version = G960NKSU1ARJ2
CSC version = G960NOKR1ARJ2

You can use combination firmware to change the CSC to KOO. Below is the reference,

I have a Spanish 976B, (Vodafone Spain, CSC ATL), so firmwares specifically for my CSC are way behind the latest ones.
So far I've been flashing the latest files from CSCs such as the ones from UK, do you recommend to flash all BL + AP + CSC + CP ? Is the CP (modem) the same ? Is it only the CSC partition that changes from country to country?

Recommended Firmware for Unbranding a Samsung Galaxy S20+ (SM-G985F)

Hello community!
I recently bought a Samsung Galaxy S20+ (SM-G985F) which is carrier branded and sim locked. I am looking to remove the carrier branding by using a unbranded firmware. I am trying to find an unbranded firmware that will not affect the functionalities of the phone ( VoLTE, VoWiFi etc..) . Would this be done by finding a firmware with same PDA but different CSC?
Current Branded Firmware:
Version G985FXXU3ATG4 / G985FOWA3ATG4 / G985FXXU3ATG4
Product Code: PGU
Would this firmware work?
Product code LUX
PDA G985FXXU3ATG4
CSC G985FOXM3ATG9
Thanks in advance for your help!

@servenaya
if you have a sim card of Guatemala and you want to keep VoLTE, VoWiFi etc.. for this country
install Version PDA G985FXXU3ATG4-CSC G985FOXM3ATG9
and change your CSC to GTO ( with préconfiguration for TIGO_CGU , PCW_PA and Claro_DR )
LUX have only préconfiguration for Luxemburg ( Proximus , POST , Tango , Telenet , Orange B and LUX )
regards

@yakapa40, thank you! This information is very helpful. I do have a Claro Guatemalan sim and even though the carrier does not support VoLTE, or VoWifi, I would like to keep this features in case they implement them in the future. I did find a firmware with the recommended PDA and CSC (Country South East Europe, Product code: SEE, PDA: G985FXXU3ATG4, CSS: G985FOXM3ATG9). Would this firmware work? From what understand, I would have to first flash this firmware, then change de CSC with Samkey to GTO and lastly, factory restore the phone. Is this correct?
Also, would you recommend using Samkey to perform a carrier unlock before changing the CSC or could I do it later on? I read that Samkey only works for phones that dont ask for unlock code. Mine does ask for a code when I insert another carrier's sim.
Thanks in advance for your help!

@yakapa40 Thank you for your help. You are extremely knowledgeable on this topic! To be honest, I just realize how little I know about flashing even though I've been doing it since 2012. I feel like I understand firmware flashing less than I did before.
I just have a last question. If I flash the firmware with a CSC NEE, and than do the CSC change to GTO, which CSC will be used for future OTA updates? What I mean is, if there is a new NEE firmware will I get it, or will I have to wait for a new GTO update? Sorry, I am little confused with all of this.

G985F OXM is a multi CSC so if you flash the firmware with a CSC NEE , you will get XEF CSC by default
, and when you change to GTO you will get GTO OTA updates

@yakapa40, I was finally able to flash the phone. I followed the steps and got the GTO CSC and the unbranded firmware working! Thank you for helping me throughout the whole process. The only down side was that I still lost the VoLTE and VoWifi options. When I look at the Sim Card Status menu, the IMS registration Status is "not registered". :crying:

SM-G781B - CSC: XSA (Generic Australia), OPS (Optus), VAU (Vodafone), or TEL (Telstra)

Hi Everyone,
I'm from Australia and recently bought a SM-G781B off eBay...
Turns out it was a UAE variant and Samsung Pay is all messed up.
I've flashed the phone a few times now using ODIN, trying to get the right CSC correct for Australia (G781BXXU2CUB5) for either of the following CSC's;
XSA (Generic Australia), OPS (Optus), VAU (Vodafone), or TEL (Telstra).
The issue I have is all the Stock Firmware's I've download and flashed keeps registering my CSC as XME (Malaysia)...
Phone INFO app doesn't even detect any other CSC's in the package
I've tried downloading the correct Firmware packs from the following and none gives me the correct CSC for Australia;
https://samfrew.com/
https://www.sammobile.com/
https://samfw.com/
App: Frija Firmware
Does anyone know why this is happening, or can upload/direct me to correct firmware either XSA, OPS (Optus), VAU (Vodafone), or TEL (Telstra)?
I'm totally at a loss now...
Any help would be much appreciated, thanks heaps in advance.

from what I've read recently Samsung has stopped people being able to switch as of android 11.
maybe... I stress MAYBE according to your countryman Hugh Jefferys, if there's a lower version of firmware on the same binary number you might be able to downgrade and then that might mean you can switch CSC.
this is someone who's never even tried changing CSC telling you this so your own research is obviously the only thing to put some faith in.
good luck

XSG (UAE) firmware is part of the OJM multi CSC, whereas XSA/OPS/TEL are part of the OLM multi CSC. This means that it is not possible to simply flash XSA in Odin as the multi CSCs are different, you would first have to use the combination ROM to change from OJM to OLM and then you would be able to flash any OLM CSC firmware, whether that be Australia, Singapore, Malaysia, or Thailand. I'm an Aussie myself, I got my phone from JB Hi Fi but switched it to Thailand CSC since XSA updates are horrendously slow (Samsung Pay does still work on Thailand CSC as does VoLTE/VoWiFi). For your case though, I'm afraid you are out of luck in terms of changing the multi CSC with the combination ROM, if you are on One UI 3.1 then the bootloader version is U2 whereas the combination ROM bootloader version is U1, so you would not be able to flash it anyway. Also, I tried to flash the combination ROM while my bootloader was still on U1 because I wanted to change from OLM to OXM (Romania CSC) for fastest updates, but Odin was not allowing the flash first because of "please get the approval to flash factory images (pit)" which I fixed, then "please get the approval to flash factory images (abl)" at which point I gave up. So as I said before, sorry but I don't think there's a lot you can do Unless a U2 bootloader version combination ROM is leaked which may or may not happen and you can get around the Odin not allowing you to flash it issues, the phone will unfortunately be stuck on UAE firmware (unless there are other countries part of OJM which you could switch to for faster updates).
Hopefully this helps you.

I have the same model! I changed my CSC but for some reason chat features in messaging app doesn't work now..other than that, all's good..

Your software version is was originally XSA, so you wouldn’t have any issues flashing it with XSA and defaulting to XSA instead of another region. The CSC will automatically default back to XSA.
Mine unfortunately defaults to Malaysia XME when flashed with XSA firmware.

Thanks for the detailed reply.
From what I’ve tested, I have no issues with flashing from XSG OJM Multi to XSA OLM Multi. You can do this provided the FIrmware security number is the same as your current revision. You can’t however flash to a lower security value. See image attached.
The current firmware security value at the moment is “2” running One UI 3.1, Android 11. We can’t downgrade to any security firmware version “1” types with Android 10. If we could, then you can use multiple methods to manually change the CSC .i.e through Google Dialer or IMEI trick.
All the Firmwares at the moment are still Muti regional, unfortunately there doesn’t seem to be a way to change the CSC manually even though they are Multi regional.
All XSA firmwares I’ve downloaded and flashed will keep defaulting to XME as that’s the default unless my original CSC was XSA to begin with for it to detect.

I think the only option at the moment is to use SAMKEY, unless someone comes with with a new Android 11 method...
The other option is to root the phone and ADB to change the CSC, however this would trigger and break KNOX securities.
I did check Samkeys update log and they state it’s supported now, this method wouldn’t trigger KNOX;
VERSION 3.63.9 (PLANET EARTH'S FIRST)
- Added support for G780F (Galaxy S20 FE) ALL BIT
- Added support for G781B (Galaxy S20 FE 5G) ALL BIT
- Fixed FAIL(16) on Slow PC's
- Fixed FAIL(20) on G780F
They’re actually up to VERSION 3.71.9 now.
Might be worth a try.

I can confirm SamKEY works on One UI 3.1, unfortunately it is paid but it does work. You can get an account for cheap from eBay with 1 credit on it which is all you need to do the CSC change. Using it I was able to change from XSA to THL (with no data wipe at all which really surprised me).

Trust me you wouldn't want XSA firmware anyway, the updates are terribly slow for it for the S20 FE 5G (not sure about 4G), it tends to get security patches a month after they should've came out, for example it got the March security patch in April which is pretty awful imo. I think it's the slowest CSC in general for the G781B, if you're on OLM multi CSC you're much better off switching to THL where the updates are a lot faster.

That's interesting, I didn't think it was possible to change between multi CSCs like this without the combination ROM (how you were able to switch from OJM to OLM). If you try to switch to an OXM multi CSC such as DBT or ROM from OLM multi CSC, what happens? Does it work? I'll be honest I never tried it myself but didn't have the motivation to try it anyway as I heard it wouldn't work.

Hi There,
Yes, im sure it works provided the security firmware version is the same as I mentioned above.
I also changed to BTU to test.
I can't test for you any longer as I've returned the device for a refund. Will go buy an AUS XSA Variant.
Attached are the images of my original and changed firmware for your reference.

That's very interesting, when you get the XSA variant can you try and see if you are able to flash a CSC such as ROM or DBT on the phone successfully using Odin? I would love to know if it was possible for this to work or not, I'm on THL myself after changing from XSA and did not think it was possible to switch to a different multi CSC (from OLM to OXM).

Yeah that's true no 8GB variant sold here as far as I know not even on the Samsung website and we don't even get eSIM support either

Is there an update/workaround on this issue?
are there any methods that work without samKey?
Noticed that the dialer app that was once able to record calls, is now recording only me talking, since the latest OTA updates on the stock firmware (updated to oneUI 3.1 and Android 11).
I'm also on XSG (OJM) firmware and want to change CSC to enable call recording on galaxy S20 FE 5G (model G781B).
Would love to know how can it be done.

thanks!

The SamFW FRP Tool can tell you which CSCs are available on your phone already, and can automatically have the CarrierPreConfig service trigger a CSC update. Only need to enable USB Debugging. No root, no reinstall.
But if your phone doesn't have the CSC you need already, download Frija, or another firmware download tool, you'll be able to download and install an OXM Multi CSC firmware (such as XSA, OPS, TEL or VAU), and install it via ODIN tool.
Be sure to select HOME_CSC to keep your data, and backup first.

Question Install CSC file from different model firmware

Hi All,
I have a Samsung Z fold 4 ‐ SM-F936N model (Korea version). I want to use it in India. Can I flash BL, AP and CP from SM-F936N firmware and CSC and Home CSC from SM-F936B (india compatible version)'s firmware (CSC as OXM, and Home CSC as INS)?
Want to do this primarily for Samsung Pay and removing Korean telecom files which came installed by default.
Also, assuming it is possible, will it impact OTA update?

I Can´t speak without doubs, but, AFIK, you can´t mix firmware files nor use firmwares from different HW versions...

Flashing firmware does not change csc u have to use something like samkey or samfw csc changer

Can you use 5G in India I have the same model and I can’t I want to use 5G

I successfully flashed my fold4 from US Verizon to US AT&T but video call doesn't work. Flashing from completely different region models might be more problematic.
