Hello. I just got a Korean Z Fold 4 and now I was wondering if I could safely change the firmware to the Indian firmware. Any guidance for the same would be highly appreciated. Thanks.
Model Number- SM-F936N
What are the benefits of doing this?
The only reason why I wanted to do it because I could not use certain apps and certain pre-loaded SKT mobile apps were installed which I could not delete.

Have you tried changing your csc to KOO which is unbranded using the samfw tool? https://samfw.com/blog/samfw-frp-tool-1-0-remove-samsung-frp-one-click
Not sure if you can try and change it to an Indian CSC of your choice. But you can try changing your csc first to KOO first which will remove those bloat and restrictions a carrier csc has.

I heard that flashing another variant csc will lead to hard brick.

flashing another firmware variant could lead to a soft brick. Changing just the CSC wont brick your device

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.
I'm living in europe and I'm using S20 Ultra exynos variant, I'm planning to get S20 Ultra Korean variant to get the snapdragon 865 chip. But my questions are is it possible to debrand it? I read few articles that it has so many bloatwares, also is it possible to unlock BL and root it? My last concern is about the 5G, wonder if 5g work on my country with the Korean variant.
Thanks.
I'm owning a SM-G981N, carrier branded phone. Regarding bloatware, there are plenty of tutorials that can be found here to get rid of the majority of bloatware. The only way to be completely bloatware/carrier info free is to change CSC and flash the unlocked rom for your device. It seems possible to do with some third party software (samkey), but I haven't done so yet.
I have OCD when it comes to bloatware and or carrier info, I can't stand the fact that something is not original samsung. I have to say that after removing bloatware, except for the bootanimations, I really don't notice that I'm on a carrier branded phone anymore. If you dig deep enough, you will always find a handful of settings/options that shows you are on a carrier phone. Besides that, no problem at all.
I can't answer your questions regarding unlocking BL or rooting, but i assume in the near future this would be possible (if not already).
For 5G, you want to check your 5G provider's data protocol. If your phone supports it, then it should work no problem. Data for your phone can be found anywhere, example: http://phonedb.net/index.php?m=devi...ultra_5g_td-lte_kr_256gb__samsung_hubble_2_5g
Good luck!
That's possible my friend. I have successfully debranded over samkey from KTC (KorenTelecom) to KOO (OpenKorea) without loosing any of my data on my phone. I'm also from Europe!
Thanks again to @mishufac

Hi Mate,
After debranded, are you able to use Volte, wifi calling, 5G in Europe on the SD865 version.
Thanks
No 5g here at the moment. I think you need your home csc to use voip and wifi calling there but I'm not sure!

Yesterday I succesfully changed my CSC using Samkey. I've already flashed the KOO firmware of the rom prior to changing the CSC, but according to Samkey support, the firmware for these korean phones is the same. This would mean only changing CSC should debrand your phone. I managed to change CSC without any loss of data, it simply reboots afterwards and it's fully debranded!

yes I have g988n and changed to KOO with samkey if ur 5g band in Europe in n78 5g will work but regarding VOLTE it may not work
Yesterday I debranded my SM-G988N, different logo when booting and lots of Korean bloatwares. First I flashed it via Odin (KOO firmware) then after that I used SamKey to change CSC.. Credit needed is just 1. So now my phone is debranded already, back to Samsung logo when booting and no korean bloatwares.
New firmware available with camera improvements, may security patch and system stability improvements!

Could some one grab a screen shot of your NFC settings, please.
I noticed on a Korean tech YouTube video, they have an extra option in the nfc settings.
I think it's related to nfc door locks etc.
try getting the hong kong version , that has the snapdragon as well and is over 100 cheaper than samsung prices
I just bought the Z Fold3 from korea its unlocked but it has the annoying korean bloatware i would really like to change the CSC from SKC to KOO please help

I downloaded patched ODIN and flashed the latest KOO firmware available for SM-F926N. Nothing changed at all. The phone still has all the bloat and SK Telecom settings menu options.
Not sure where I am going wrong.

This is not possible now AFAIK, I have tried to change the same on s21 ultra nothing worked. I even tried samkey ...money waste.
Only solution is root and change using phone info.
You can change csc to KOO however I am still facing network issues in India. Trying to find if somehow I can get to INU csc without root.

Hello, I currently have an SM-N976N.
I bought refurbished and live in Ireland.
I am looking for a compatible firmware that's not Korean but not having much luck. I can't flash anything in Odin except n976n firmware, and even that didn't seem to get rid of the sky telecom provider bloatware and branding.
I can provide CSC etc if anyone thinks they can help! Looking for something like a global or UK Ireland Unlocked like the B...
tried to flag KOO firmware...I used CSC as opposed to home Csc but I also used userdata file in Odin as well.
The sk splash screen and bloatware is still present.. There was a warning or info message on phone after I flashed, and then it rebooted again. I couldn't read it as it was in Korean.
Also, if there's no way to change to a euro firmware, is there any way to change bootloader/recovery/download language?

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?

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.
