Benefits of changing CSC code?

I live in the UK but my phone is a grey import and has csc AFR. I have the option to change it to a UK csc but it will factory reset my phone.
Are there any benefits for me if I changed my csc code to a UK one? I have just updated my rom to the latest french 4.1.2 but my csc has stayed the same.

if you change the Csc to United Kingdom Unbranded you will not have the 4.1.2 update, the BTU (uk unbranded) Csc is still 4.1.1 in galaxy note 2. As of other benefits you wont even see a change the Rom is the same and everything in it is the same. so stay with that csc.

There is something like HD Voice and this service might not be enabled if your CSC code doesn't agree with the country you live. And I think that thanks to proper CSC your mobile internet settings should be set properly too. I don't know if that has some importance for available services in Play store, but it might have.

Hd voice isn't available on my network (o2) and my Internet settings are set up correctly from when I first put my sim card in my phone. Also the play store has been working fine for me so far.

Install the latest stock rom.
mb2 for france.
Then change csc.
If you wouldn't mind a factory reset then you can do it.
But no major benefits.

hello, I'm trying again in this topic cause maybe nobody saw my previous attemps.
I want to change csc but cant cause I have this error "com.android.Preconfig not found and changed to manual mode"
tried the csc select app and mannualy with the 272 imei thing
little details: came from a branded carrier phone, then unlocked with galaxsim app. I use a XEF rom and I want to have a XEF CSC.

Got the same problem had branded phone with 4.1.1 then install 4.1.1 XEO and change CSC to BTU, after that install the XEO 4.1.2 and now i cant change CSC?

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

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:

SM-G986B is Multi CSC device. Since Switzerland and Italy are in the same region both CSC's should be pre-installed on the device.
Try this - Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press dial, you should see a screen with the list of available CSC codes for your device. Select the CSC that you want and tap the Install option.

I changed mine yesterday from EVR to BTU. Took SIM out then used samkey took less than 5 minutes then when it was done an update was available for me straight away

My current csc is this:SAOMC_SM-G986B_OXM_SWC_QQ_0025
RFCN30KLS0N
SWC/SWC,SWC/EUY/SWC
Is it possible to change this csc to ITV through SAMKEY?

The Samkey method would only work if the security patch on your phone hasn't been updated past July 2020. Otherwise you will get an "unsupported BIT" error.

In this case you're stuck (like myself) with whatever csc you currently have unless you root your device. I haven't rooted any of my samsung phones (my primary handsets) since my S3 days as I had no need to. So I'm not familiar with the process for sammy devices.

Samkey must have updated their program recently then. When I tried that 2 weeks ago, it didn't work. Thanks for the heads up. I'm going to change my S20 to BTU.

Yes, you'll have to follow 2 different tutorials if you have a Non-Samsung phone & if you have a Samsung phone, then just follow the first tutorial below & have fun.
In case of a Non-Samsung phone, make sure to install the bp.tpk app on the 4.0.7 itself, i.e. when you flash the Brazilian firmware & before upgrading from here, so you don't have to downgrade to install it.
Link to Brazilian firmware - https://drive.google.com/folderview?...IGMXFCQUzsBt7q
You need to flash this as the firmware file, instead of the one listed in CSC change OP below, use combination firmware from the tutorial.

Ok so it's because i got the LTE version ):.
You're lucky ! I'm waiting it so much.

While I could jump through these hoops no problem, it's too "Rube Goldberg" for me. I have the LTE GW2, USA, updated to the latest 5.5 release.
I got BP functionality by joining the UCSF Blood Pressure study "My BP Lab".
Don't do this just to get BP reading capability on your watch. There is some serious participation requirements, and it will interrupt your day 3 times to take your BP as scheduled, and then answer a bunch of questions on the phone companion app. However, you can then check your BP any time, so you will have the feature.
For me, the additional data I get as part of the study was more than worth it. The main point of the study is to correlate stress and BP, so there are also optional exercises that can be performed during each check in to see how they affect BP. Participation is 3 weeks from the time you sign up, the study is on-going.

is there anyone have the most new firmware for R825F？？？

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.

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.
