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

Hey Thanks for your reply....I am currently on BRI and wanting to move CSC to XSA but XSA being single CSC and BRI multi CSC I think it is not possible yet....
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:
Hi Guys,
I got a F936N which is Korean. I want to change it to OXM since I am in the UAE. 5G is not working on the phone and I got some weird carrier settings for Korea.
I tried using the SamFw_Tool to change it to a CSC and also tried flashing the OXM firmware via patched Odin, it is failing.
One thing to note is that my device has 1 SIM and 1 e-SIM. The devices here in the UAE are 2 physical SIMS. Not sure if that would create a challenge. I just need 1 SIM to work.
Is there anything else I could try?
Thanks.
Bump. I have a OXM CSC tablet that I Want to change to a US CSC
Hi, I have the same issue. I got a F936N which is Korean and I want to change it to OXM as I am in India. Someone please help.

Hi. I have S20 Ultra SM-G988B/DS, it's International model, original CSC is VAU, and I installed OXM CSC Firmware, I use it in United Arab Emirates with XSG CSC, but it also shows XFA CSC, idk why. After updating to OneUI 5.1, i can only see eSim option for 2nd sim but 2nd Physical sim is not working and nothing in the settings. I tried to change the CSC but no luck. Kindly help
