Change CSC on a rooted G960F? possible?

Hi All,
I have tried searching for a solution to change CSC Code on a rooted G960F BRI model but all threads are about changing it without root (and that doesn't work).
Can someone point me to a thread maybe, that provides the steps to change CSC on a rooted phone?

You should be able to change it without root as long as the new CSC you are flashing does not contain the phones original CSC
For example BTU is Multi_CSC and contains XEU, so if your phone was originally XEU and you wanted to try and switch to BTU you cannot because the phone will automatically choose the original CSC from the Multi_CSC
You would need to flash a CSC that is either a single CSC or does not contain BRI
Look on the play store for CSC changer for a root method

if you flash non Indian roms , you will lose native VOLTE calling function.

I wouldn't mind using it, I have the Wi-Fi version so what an effect me. But it probably won't work I have the SM-T830.

Any screenshots?

No

Will I still get OTA updates in the future if I flash this region's firmware and will I lose any data

hey all- any reports on whether something like Swift Installer will work on Pie? it does on my Pie on Note 9 but i know it doesn't on the S10.

Probably not, this should be a multi CSC ROM, so unless he change his CSC manually, he will stay on INS (India) CSC

Indian CSC (INU or INS) is not available in the French firmware. So when we flash CSC, it'll change the default CSC to French. This hap to me when I flashed French Oreo rom on my tab. I had to revert back to Indian rom to get the VOLTE call feature back.
Please excuse me if I'm wrong.

Can someone please share the boot image for this ROM? I'd like to root it using this method here: https://forum.xda-developers.com/android/software-hacking/root-recovery-root-device-magisk-t3779454 (rooting without recovery) because trying to flash the TWRP recovery that we currently have failed.

I am not sure if the French ROM is multi CSC, if it is, it should include the INS CSC, I flashed my Note 9 with Indian firmware but it was multi CSC, and my phone still have the MID CSC not changed
I didn't have the time to flash my tab yet, I'll do it soon and report if my CSC changed

Flashed my tab, CSC have been changed to XEF but I am using it without a Sim card, I used the home CSC so my data stayed intact without wipe (for testing because I factory reset it manually to avoid bugs)

If you've upgrade can someone see if you are able to downgrade back to Oreo? I am happy with the Oreo rom and hate when they make it so you can flash a lower build incase the new one is not up to par. Its odd that the French version is up before the Korean international version.

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 ?

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:
