I've just changed my s21 ultra csc from EVR(EE) to BTU using the samkey way. flashed over the AUDA firmware- didnt wipe anything and all good now. shows BTU in download mode and under softeare version. I have 2 credits left on my samkey account if anyone wants to do theirs? (at small cost of £3.50 and you can have the login details).

[Samsung Galaxy S21 Ultra] balsaadi:
Hi everyone

My device is SM-G998B (international, exynos, dual sim) -- it is rooted -- original & current CSC is XEH

I want to switch my CSC to RWC (Rogers, Canada) to enable Wifi Calling, VOLTE, 5G, etc..

--> I looked for firmware on sammobile but Canada is not listed (?)

--> I tried to access preconfig menu to change CSC but code does not work (*#24320# and *#243203855#).

--> I tried the link in this forum *#272*(IMEI)# and I get "unknown application" msg

ANY help is much appreciated.

Thank you
[Samsung Galaxy S21 Ultra] Nettwerk:
You can't get RWC CSC on your phone. If even you get it than you will break the phone. For Canada you need with Snapdragon chipset.
[Samsung Galaxy S21 Ultra] ms5678:
I have SM-G998B with CSC code as XSG (UAE version). I tried odin method with July INU version but couldnt change CSC. Any advise
[Samsung Galaxy S21 Ultra] Nettwerk:
To change csc on exynos variant you need Samkey. Which is remote service. On Snapdragon phone you can change csc flash your selected carrier firmware.
[Samsung Galaxy S21 Ultra] balsaadi:
Thanks for the response . What about the Hong Kong SD? Will I be able to flash RWC onto a rooted G9980?
[Samsung Galaxy S21 Ultra] Nettwerk:
I can't find thread but one guy flashed N986U on N9860 or other way. But of corse wasn't easy. And I don't recommend you to do this. You can flash RWC on G998U.
[Samsung Galaxy S21 Ultra] balsaadi:
Thanks again for the info. Why would flashing RWC on G998U be any different than the G9980

The issue I was concerned about is band alignment with my carrier so I dont know what the speeds will be like. Only one 5G band (N41) checks out.

I read through so many threads and did come across people using G9980 in Australia and having features like 5G, Wifi Calling, etc..
[Samsung Galaxy S21 Ultra] Nettwerk:
G9880 is for China region, G988U North America, G988W Canada. (I can say between G988U and G988W no difference except firmware and maybe some extra bands.)

So 5G Bands.

G988U: n2, n5, n41, n66, n71, n260, n261

G988W: n5, n41, n66, n71

G988B: n1, n3. n5, n7, n8, n28, n40, n77, n78

G9880: n1, n78, n79

I was in the same boat when I looked for Note 20 Ultra. Unfortunately US variant doesn't support n78 band. So for me no chance ever get 5G in the europe.
[Samsung Galaxy S21 Ultra] DonJulio999:
i recently purchased a s21 ultra from abroad and live in USA. csc shows its from vietnam(xxv) but i dont get any 5G here in America. does anyone recommend i change the csc to get 5G data or am i out of luck with ever seeing 5G on this device?
[Samsung Galaxy S21 Ultra] ione2380:
Search what bands your carrier require for 5G vs the bands that your phone supports. If it's an Exynos you're out of luck.
[Samsung Galaxy S21 Ultra] ivanox1972:
I have note 20 ultra N9860, but should be same boat- android 11, snapdragon, TGY CSC...

So, I can just flash CSC field in Odin of BRI fw to change csc to BRI? Or whole fw (all 4 files)?

Phone is not rooted, bootloader is not opened.

Thanks
[Samsung Galaxy S21 Ultra] Laucien:
So, I have an S21 that is apparently from Hungary/T-Mobile (TMH/TMH). The phone is unlocked and works great so far in Germany so I never bothered to change it... but now I kinda want to.

I'm kind of at a loss on what I should do. When I got it I downloaded the German unbranded firmware and flashed it with Odin but when I set everything up it was still in TMH and I left it like that.

What's the correct procedure? Flash with Odin? Buy Samkey credits and use their software?. The phone model is SM-G998B/DS.

Answering my own question.

Used Samkey to changed the CSC code and everything went great. Only thing extra I had to do was that my S21 had the latest August firmware which seems to not be compatible with Samkey yet so had to downgrade to `G998BXXU3AUE1` -> Change CSC code -> Upgrade again.

[Samsung Galaxy S21 Ultra] Amr Faried:
Hi there, I'm currently on G998BXXU3AUG4 and I can't change the CSC using Samkey, it says not supported.

My questions here are, Can I downgrade to AUE1?

When I downgrade, I will lose my data or not?

(flashed CSC file or Home_CSC?)

Will it brick my phone?

When I downgrade -> change CSC code -> Upgrade, the new CSC will be the desired one or the old one?

Thanks in advance for your help, much appreciated.
[Samsung Galaxy S21 Ultra] amirage:
I'm not sure if downgrades are possible with the new updates since Samsung clearly mentions it in their update window...If in case you can still downgrade via Odin nothing will happen as long as you flash the correct stock rom without or without wipe.

[Samsung Galaxy S21 Ultra] ser8210:
Hi.

This app does not break the knox.

Maybe it's not in many forums because the csc change still has limitations like some devices don't respond to the *#0*# code and others don't have the right csc, for example to get call recording, which is its most widespread use .

For the change of csc, the program uses an old acquaintance that is none other than the sending of certain AT+ commands that, out of respect for the developers, I will not publish.

There are many AT+ codes and examples on the Internet.

I seem to remember that there is a thread here on xda that talks about it.

Some people say that the commands used by the program come from the Samsung leak published by lapus$, but it is not clear.

I found some references in the leak, but I don't have time to search 200gb for those specific commands.

I didn't find anything strange in the program but since I don't have the source code I didn't search everything it contains, I just focused on the method it uses to change the csc and something else, I used reverse engineering and just out of curiosity.

[Samsung Galaxy S21 Ultra] mpore14:
Hey Salu2,

Thanks so much for your reply. Appreciate it.

Us at G9980 thread wonders why it's impossible to switch between TGY and BRI. Maybe this would help.

Also, it's interesting to know that Samsung had those leaks.

Cheers
[Samsung Galaxy S21 Ultra] ser8210:
Hi.

The problem may be due to these csc being unique.

That is, for example the csc dbt is part of a multi csc firmware so it contains a large number of csc and you can switch between them.

Other regions are of a single csc code and that is why it does not allow to make the change.
