Question Change CSC S21 Ultra 5G Exynos - Samsung Galaxy S21 Ultra

Just wondering if anyone has recently changed their CSC to allow them quickest access to updates and the Beta program?
My CSC is for O2 UK and I'd rather it was generic.
Being from the UK mine is an Exynos model.

Did you try and downgrade to an older build? I'm sure I read somewhere that worked. I just was hoping someone had a definite answer for me.

I only tried the September and October updates as far as I know u cannot downgrade due to the latest Bootloader

Someone on XDA confirmed that
G998BXXU3AUE1 can be used to downgrade and change the CSC I am about to try it ill keep you posted that's the lowest I can go due to the binary

Yep just flashed G998BXXU3AUE1 went through setup and turned on adb, downloaded samkey logged in, and changed my CSC from VOD VOD VOD VOD VOD to BTU

Thanks I may try it myself. How do you buy credits for Samkey? Do I really have to buy 45 dollars worth? That's the lowest I could see.

Does the XID CSC change affects the phone ? I mean the phone still remains a dual SIM phone?
Also, volte and WiFi calling are still there to XID CSC?

Grab your region's version, then flash via Odin.
I find it easier to not flash the latest version, but to an older version (4.1.1) just to make it feel "Stock-ier".

Record calls with Note 8 recently updated with last firmware (android 9)

We need to record calls without rooting our devices (mine is a Samsung Note 8 updated to Android PIE).
All third party apps are not working anymore because Google (shame on you) blocked them with android 9.
We need a quick solution from XDA because the most of the Producers brands don't want to provide for that (only Xiaomi provide a native function in his smartphones, from what i know). Samsung seems not interested to this request of the users.
Please develpers focus on this...million of users waiting a quick solution!!!!
Thanks in advance.

Actually You can. I changed mine from NZC to INS. Download the particular countries firmware and flash it with Odin.
I did it like 1 year back but just google it. There are steps. Knox will be still intact.

Hi, i have taiwanese firmware BRI (in Sammobile i can see that Taiwan and India have same the same CSC N950FOXM5DSB2).
I have not record call native function with this firmware. Are u sure that in Indian software that function is present? I mean in Note 8 (SM-N950F DS) dual sim.
By the way, if i decide to flash indian firmware .....to change CSC what file is the one to use? home_CSC or CSC? I've read that someone flashed the other country firmware but then CSC didn't changed ....
Can u link me a video to do this? or a forum with a clear instructions to use a firmware of another country?
Thanks in advance

Hey Try this. *#272*Device IMEI# if it shows list of CSC select the one you desired.
Caution: It will factory reset the phone. When booting don't insert sim card as it will try to change back CSC to your sim country. Let me know if it working.
I had to flash through ODIN coz in NZ phones are network dependent. but asian and european version have multiple CSC so it should work fine without root.
HIT LIKE IF WORKED
---------- Post added at 12:07 PM ---------- Previous post was at 12:05 PM ----------
If it didn't work let me know. Got few idea in my mind.
You should be presented with this pop up once you enter the code in dialer.
maybe it's enough that i only change my CSC (now BRI) to INDIA (INS)..to enable record calls native function.
then hard reset and let update the smartphone.
I have Taiwan official last firmware with PIE now (received OTA) and i've read on Sammobile that Taiwan and India have same firmware numbers.
So maybe i don't need to flash indian firmware with ODIN....what do u think? Should it work this way?
I will test when i have time (i need the phone and i dont have time to waste reinstalling and configuring everything again)....
Before this test i wait other suggestions please...thanks in advance

Changing csc for N960N - Android 10

Update: 1
I was able to change csc in Q for our n960n and this is how i did:
I flashed Superstable Q rom and the Dev included the option during installation in aroma to chose a different csc, i keept using the rom for 2-3 days and didn't have any issues, but before returning to Pie i did tested Dr.ketan's Q rom rom and Alexndr's-devbase Q rom and in both cases i still had my csc.
Click to expand...

Im opening this thread to find a solution on how to change the csc on note9 n960n in android 10.
Doing so in Android Pie was easy ( of course with help from this great community ).
there is a tool provided here called - Csc selector - which i used and it worked great ( for note8/note9/note10), some roms offer the option to chose during installation.
when i updated to android 10 it changes the csc i had, probably because Samsung made some changes so i guess we will have to wait until more csc are released with updating process still in the way.
i will post any news/tutorial i find here and hopefully you too.
Almighty bump for this frustrating problem. I too am on the incorrect CSC on Q...everything works so I just ignore it but I can't help but think I am not getting the reception I would otherwise be getting if all available bands were utilised. I am on n960 FDS and should be on XSA CSC but I'm on XSG.
I'm not sure there are even Android 10 roms available for XSA region code yet.

We might be near because Samsung keeps releasing android Q to more regions for n9 and s9 now started to get its update.
I'm not sure how they've done it but there is a fix if you are prepared to flash a non-stock rom or already have.
You can flash either Alexandr's Devbase or Zeus Rom beta from the zeus telegram group, and before flashing rename the rom zip to include your appropriate csc followed by _. Read first post of devbase for details, it worked a treat for me and I didn't even think XSA was available for Q roms yet.

that doesnt work for my device i have an n960n and the only supported csc are KOO, KTC, LG, SKC, i can change to one of those in alexandr's rom ( by the way i love that rom and i came back from it to pie because of this problem) but no to n960f csc's so i guess i will have to wait until there is a mod to change csc in android q.
thanks for your reply.
Maybe you can try with Samkey software, but it's not free.
Even I am in this boat, I downloaded an n960f rom and tried to flash the csc on my n960n.
And yeah it failed.
Wish it were an easier process.
I just want the random reboots to go away on q.

they offer only sim unlock, i didnt see in their web page that they can change phone model, your reply made me think if we could change the bootloader/model completely with a tool ( my friend has some of those he uses them to unlock/repair/flash phones).

No need to reset device to change csc if you already have a multi csc firmware for example OXM. Use phone info or something similar from play store to check.
I used samkey (purchased 2 credits from ebay for $5) and in a minute changed csc to THL
Click to expand...
Click to collapse
Buy samkey credits from ebay (you need 2 to change csc) you get them in a form of a username and password
Download samkey from theit website
Connect N10+ to your pc with the cable you got with your phone
Open samkey, input username and password, input THL in the csc field and execute. (my first attempt failed with a server error the second one suceeded)

thanks for your input but this model of note 9 - n960n is made for Korea and i has only 4 csc - KOO/LG/KTC/SKC , these csc have limitations when used outside South Korea which is the case for me, because of this i have network issues so i want to change it to a n960f model or multi csc so i dont have those network limitations.
i changed my phones csc to multi csc with a flashable tool "csc selector" and i works great but this works only in PIE, samsung made some changes in Q and it doesnt work.
Oh, ok, didn't know the story about n960n.
I need to change too!

Can i change n9600n firmware to n960f ?
Please advice me, I am new to this kind of works, thanks in advance

If you mean N960N, Yes you can as i mentioned couple post ago.
You need to root your phone by following the instructions in note 9 guides forum, then go to note 9 rom development forum and choose the one you prefer.

Question CSC still has the 5th one as "TNL" after succesfull change?

I bought a used S21+ and it was a T-Mobile branded model (Dutch). It had TNL/TNL/TNL/EUX/TNL. I use a Vodafone SIM so it would not do VoLTE and VoWiFi and such.
So, I downgraded it to May 2021 AUE1 so I could use SamKEY which worked fine with eBay credits.
I wanted to have it full unlocked unbranded as it will probably get faster One UI 4.0 for unbranded. So I went for PHN which is Netherlands Unbranded.
It worked fine in SamKEY with eBay credits and it passed and rebooted with no errors and instantly gave me the My VOdafone app install prompt so I knew it worked.
VoLTE and VoWiFi are working fine now, however, upon checking my CSC in Software Info I noticed it now shows PHN/PHN/PHN/EUX/TNL. Why is that last TNL still there?
Can I somehow make it FULL PHN? Or does this last 5th TNL not affect anything?
Back when I had my Note 9 and also changed CSC on that one (Vodafone branded to PHN unbranded) it fully changed all of them so I kinda expected this one to do so as well..
