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.
Any work around to use 5G in India ?

Hi,
c
You have to use the same model to flash in Odin. 976B is not 976N.
You can flash the KOO firmware for 976N which is the unbranded version (I bought it myself at a Samsung shop in Seoul).
I tried to flash with 976B and got errors. I flashed with KOO 976N but srill i have brand of KT when i start the phone also some settings of KT.
No idea why KT still stays after flashing

Right, because 976B is not the phone you have. You can't use a different model firmware.
Sounds like you need to change the CSC to KOO after boot up.
I used CSC for KOO byr still no lick
Let me know which CSC maybe i am doing something wrong

You said you flashed KOO firmware. That is not the same thing as switching CSC after booting up.
There is a phone menu to change the CSC. You need to do this, which will change the CSC setting on the EFS partition which is what you need to do.
Woow thank you for that. Now this is new and i didn't know it. Can you help me and let me know where to change CSC.
Thanks

The SM-N976N has 4 CSC options built-in. KOO is the unbranded Samsung code. There are 3 for the 3 major carriers in Korea: SK Telecom, kt Olleh, and LG U+
No I did not change my CSC because I bought my phone in a Samsung store in Seoul.
I have KT one , when i switch one says 5G and under screen KT.
also in setting. I am trying to find the way to change the CSC from KTC to KOO
Active KTC
Edit
Ohhh no way that bad
For me only Samsung pay ,5G, start up the phone, phone can't recognize my number rather than that everything else is perfect.
I am trying to find way to change CSC to KOO, hopefully will work

Do you mean your N10+ doesn't connect to the 5G network even if it's present and working in your zone?
Yes i don't see 5G at all even covered in my country. Always LTE+
Weird.. where are you from?
Our model is 5G, I suppose SM-976B only is suitable for 5G networks over asian countries, hope someone could tell me I'm wrong...

I don't know the specs of the B variant, but my N variant 5g worked in Korea just fine. Haven't been able to test it in the USA yet because T-Mobile doesn't have any 5g towers in my state yet.
In my country, UAE according to bands only N976N working since the are on same 5G band.
N976B isn't working with UAE network (5G). I bought and sold N976B.
Also now N976N is not working coz of carrier, KT from Korea.
Hey everyone,
I realize that posts regarding CSC are a dime a dozen, I've searched through a lot but this stuff is somehow really tough to piece together. I rarely post because I normally find everything I need but here goes.
I bought my note 10+ in Slovakia from Orange. The phone's CSC is ORS/ORS,ORS/ORS, which I think is part of the OGC multi CSC. I'm guessing ORS stands for Orange Slovakia. However, I'm using a Telekom SIM card. I'm still waiting for my android 10 update, but I've noticed that Android 10 has already come out for the Telekom Note 10+. The CSC in that rom is TMS (which I think stands for Telekom Slovakia), which is a part of the ODX multi CSC . In the past I would just flash an update from another country, but from what I gather, this is somehow... riskier? nowadays.
So my question is, could I lose warranty if I were to flash that TMS rom? Or is there a possibility that it would mess something up? I figure that that's the rom that is as close to mine as possible ? but I'm not sure. Any advice would be much appreciated.
Hi, i have same Note10+ buyed from Orange Slovakia. I flashed Multi-CSC FW ROM (ORX) from samfirm, but CSC is set to default AUT. For change CSC you must buy 2 credits from samkey.
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!
save all your data

@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:
Hello,
I seem to have a phone brought with wrong csc.

Can you guys advice ?
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.
