Tell me if this worked. Otherwise drop me an email or a private message. I will explain you the way of changing CSC without root and triggering knox. Also suffered with XXV firmware for months. Last week successfully switched to XME and using Samsung pay and Knox services.

Hi All, i manage to change CSC last week, without triggering KNOX.
I can use samsung pay and secure folder.
Method use : Binary Factory ROM
Now also can use *#272*imei#
Thanks a lot

Samsung Galaxy Note 10 Plus 5G Debrand?

Hello, I purchased Samsung Galaxy Note 10 Plus 5G. Everything is ok, no problems etc. But unfortunately it comes with Vodafone apps and widget other bloatware. Is there way to debrand Note 10 Plus 5G? Thanks in advance.

N976B variant? VDF UK?

Yes it is N976B.

Ok. And sim card?

I've the note 10 plus 5G on 3 UK and it's on unbranded BTU.
Are you UK Vodafone?
Came with only Samsung bloat, no 3 apps at all which makes a change for them.
Would flashing the BTU firmware not work?

I'm using EE. I bought from CEX unlocked. But as I wrote come with preinstalled apps. Even after factory reset.
Service provider SW version:
VOD/VOD/VOD

Updating CSC to global (GCF) cleared all carrier bloat for me, BUT IT WILL WIPE YOUR DATA IN THE PROCESS SO BACKUP FIRST.

Can you give BTU OXM firmware link for Note?

Use frija or samfirm :
replace XEU with BTU

then flash with odin AP,BL CP, CSC OMC OXM, not CSC home , sim in. Back up your data first!!!

Ok I flashed firmware BTU but I dunno why it changed to XEF... :/ I have installed now OXM firmware. Vodafone stuff gone.

As you read above, I have same. But anyway better then branded vodafone firmware.
Anyway I think need Samkey tool to change CSC to BTU.

NO! Samkey tool is for unlock the phone. To change CSC you need RealTerm and combination file for your device for access factory binary .
This is how to use RealTerm to change the CSC ...,for note 9 , which i did for note 9.

This Method is not working anymore as from S10 and Note10 Flashing Combination firm is impossible. I managed to change my CSC on my Note 10+ 5G (SM-N976B) using two credits bought from eBay on SamKey.
I had the default OXM XEF France and went to BTU.
Hope this helps

With Samkey I changed to BTU/BTU/VOD. All is good now.

And how much did credit cost to use samkey?

I paid £5.05 for 3 credits.

looks like I have to go down this road, which site did u buy credits from and does 3 credits enough to change csc?

You need only two credits. So 1 credit will left unused. I purchased here:

Info for CSC code: OSW

My device CSC code is OSW. I can't find what means. I run the dial method to know my phone CSC code. Before was OXM.
Any help will be highly appreciated.

Have you asked at Reddit?

That's where I gave my answer.

OSW is a multi CSC, like OXM is.
Based on the sim cards in your phone, on first boot after flash, the appropriate csc is selected.
Based on the information provided by OP on Reddit (CSC settings in phone info: NEE/NEE, DBT/XAA), it looks like he has both a Nordic sim and a German sim in the phone. Probably as AUT is not in OSW, DBT is selected.
Strange to me is listing of XAA (=United States) as last CSC. That last CSC would indicate country code of the country the phone was manufactured for by Samsung... but Samsung does not manufacture N975F for USA... Looks like phone was seriously messed with.

So, it was OXM before? " If the CSC of your Samsung device is OXM it means it has Multi-CSC firmware installed on it. OXM is a group of CSCs that contains multiple sub-CSCs inside it. It means that you can easily change the CSC of your Galaxy phone or Galaxy Tab. "

yes, I try to install another version with *#272*IMEI number# bud this code was not working for my phone.
Anyway, I had managed to flash another updated version (UI2.5 and security 12.2020) also OXM.
With this last firmware if I use *#272*IMEI number# still I don't get any multy-csc.
It is possible to change the IMEI of a phone?

I also found it strange that it was XAA it has an Exynos chip. Now it is NEE/NEE, NEE/XAA.
Can you change the IMEI?

No. Moreover, as tampering with IMEIs is illegal, it will not be discussed on this forum.

Forgive me, I was not aware.

Question Indian firmware with European Z FOLD 4 (SM-F936B)

I just saw online that India Market got the new update (F936BXXU1AVIH) with September security patch.
So my question is, as i have an european model with the same model number (F936B), what is the risk if i flash this firmware ? As i know that it's not gonna change my 4G/5G bands anyway, so i'm guessing maybe an OTA issue after flashing this firmware (like not receiving them as i don't live in India).
Sorry if it's a stupid question :-/

No risk, CSC HOME and all good. I do it.

Ok, thanks for your reply
And what about future OTA updates ? Will it still be working ?

Yes.

Yesterday I installed the Indian version on my European version Fold 4, there is no problem except that it does not pass the Safetypass and I cannot make contactless payments.
No Root, no OEM unloock, just ODIN upgrade (firm from Sammobile).

I confirm that i can no longer make contactless payments as well, but i never used it anyway so not a big deal for me... i hope that there will be no others bad compatibilities like this one.
Will update on a newer European firmware later or just flash the AVIH European firmware when it'll be released

I'm guessing that it's caused by the software itself and not caused by CSC. Maybe in India, Google Pay is not used, i don't know...

It's very strange that the India version does not pass Safetynet's CTS checks. I also used the Home_CSC, I had never had a similar problem. I will wait to try with another region when it comes out.

Same here....Some week ago I bought a Z Fold 4 with EUX CSC and immediately changed CSC to INS using SamFW ver 2.1, Wallet worked like a charm until latest security update installed some days ago...Now, reverting CSC to EUX, does not solve the problem...

So you're saying that you reverted back to the last Eurpoean Firmware and that you can't still use GPay ? Or you just tried to changed the CSC without flashing European firmware ?

Thanks for info. I couldn't resist and downloaded via frija. There's only EUY version at this moment. I flashed via Odin with home csc and I kept INS csc
I don't know changelog but no change on dynamic weather Widget (it's a shame this Widget lol impossible to change size or background color since 3 months)
Camera is updated, will see what's up

Did they fix Material You theming for the volume bar?
EDIT. No update in Poland.

Great Im not at home to download it hope the OTA comes soon

Bifrost has the changelog, Camera/Gallery/Security

Finally Image clipper is now available in this update.

So everyone is getting this update besides the EUX csc

Hoping we in the US get it this week.

U.S. unlocked devices, F936U1, have received a slightly earlier build F936U1UES2CWC9 update with the April patch, 9 days ago. The carrier branded devices, F936U, usually take longer for carrier certification.
