Question Is it possible to change CSC on S21? - Samsung Galaxy S21 Ultra

Hey,
I know there are lots of thread about this topic but I read pretty much all of the posts but I always gets mixed result. Some people says it's possible and some says its not.
I have G998B/DS (Exynos model) and it's running LYS (united arab emirates) and last update I got was June update! (G998BXXU3AUE1) Today I read some US models got July update!
Is it possible I change my CSC to somewhere else like BTU so I can get updates faster? Does SamKey method works? If yes how many credits do I need for changing my csc?
I know I can download framework and install it manually with odin but I like OTA updates which is pretty safe and easy.
Any help would be appreciated

And you are going to change CSC each time another country get update quicker? It is first time when US received update faster... Also 99% of us are still on June update lol

What? NO!
Have you read my post?
I said LYS is late in updates and I want to change it to other county's CSC like BTU

Leave the CSC and just perform any new updates from the regions that get them through Odin.
Simply choose the home CSC file from the update download and you get the updated firmware but keep your CSC and any network related features that depend on it intact and without touching Knox.
I really don't get the fascination some people seem to have with changing CSC.

Question on firmware

Hi,
I'm not very familiar with flashing Samsung devices so please excuse me if this is a silly question.
For awhile, I was given a Note 9 (SM-N960F) to test for work and I was able to flash the latest firmware almost regardless of the region that received the update. I'd download the 4gb file and use Odin to flash away. Very simple.
Now that I had to give the phone back, I got myself an S10 (SM-G973W) with Telus here in Canada and I'm not sure what I can safely flash. If I look at Samfirm for SM-G973W it seems rather limited, I can find the March update or the April update but that's it.
Is it because those are the only two firmwares available? Are there alternative regions I can keep an eye on for quicker updates? Is it that Canadian carries simply didn't make an update available with April security updates?
Thank you

"F" is the international model with European and Latin American CSCs. "W" is Canada only. No additional regions or countries will be available.

No Update for XSP N960F

This isn't much of a question more is it a vent of frustration towards Samsung. I am still on the July Security Policy despite Samsung claiming Monthly Security Updates. When OEM's refuse to Update their devices on time or out right at all this is when fragmentation becomes a big deal. Monthly should mean Monthly Until the end of life. No exceptions.
Thoughts?

then just update it manualy:
https://www.sammobile.com/samsung/galaxy-note-9/firmware/SM-N960F/BNG/download/N960FXXS3CSH2/286019/
you can also use samfirm tool 0.3.6 or frija app to download it with ure pc since that web site has trash speeds and flash it using odin. but be sure ure pc has samsung android drivers before using odin.
i believe you could also use samsung smart switch software to check for an update and flash it too.
so as you can see you can just update the device yourself instead of waiting. read and search xda for any of the tools and ways to use them aforementioned.

I was hoping to do that however I checked on there for mine. My product code is XSP which is the Singapore Version and the latest one is June 1st which im already on. If I were to flash a different region's firmware could I just use Home CSC to keep XSP? Thanks for the help

you can probably skip it all together. but your csc is the carrier code. if the phone is not carrier tied then you should either use the link i sent which is multi csc and would probably contain your sim CSC or find out the carrier code matching your carrier/sim.
read up on samsung and CSC for more details.

Yes. It won't change your product code and wipe your device. Rest assured.

i have the same model but i believe it's something to do with the region instead of the carrier.
In comparison withe the firmware for both SG and PH, PH received 2 updates from July (CSF9 and CSG3) as compared to SG which only received one (CSF9).

Yeah, I think ill just wait it out because flashing over a security patch seems like a nuclear option. Hopefully in arrives in the coming weeks. Thanks for the help and information though everyone I appreciate it.
You guys are touching a contentious issues with the way Samsung delivers update in Singapore.
Due to the national telcos bottlenecking the process, Samsung phones are getting much lesser updates than the rest of the world.
As an example, Galaxy Note 9 in Europe (UK/DE/FR), version N960F which is identical to the one sold in Singapore received a total of 24 updates, including 4 different built of Android 10/OneUI 2.0 and is up to date with the March 2020 security update.
In Singapore, the Note 9 received 8 updates and the latest is from October 2019 with the October security update.

Changing the CSC

Hi all
I have an A71 which is running one ui 2.1. The phone is on the South African Vodafone CSC which is XFV. My problem is that Vodafone takes forever to release the updates. I want to change my CSC to the normal South African one which is XFE. Can anyone please direct me on how to do this and if possible to do it in a way without losing my data. The model number is A715F if it helps. Any help will be greatly appreciated.
Thanks in advance
There is already a thread on this: https://forum.xda-developers.com/galaxy-a71/how-to/guide-how-to-change-csc-a71-t4156773
The updated firmware for XFV was released today so you will likely get it soon: https://www.sammobile.com/samsung/galaxy-a71/firmware/SM-A715F/XFV/download/A715FXXU3ATI8/464667/

Question So I flashed Android13 on my S8 But

hello, I have a Tab S8 with csc of ILO/ILO. I couldnt wait for my country to do OTA, they are slow, so I flashed myself android 13 with the EUX rom which belongs to same OXM. It did upgrade to Android13, but the CSC stayed ILO/ILO instead of becoming EUX/ILO. wtf?
will I get OTA in the future?
i have the same question, im from Brazil, ZTO version, and i want update, but i have this question, if i do the update, im recive the future updates via ota? for exemple i think to use the israel firmware, in my ZTO((BRAZIL)...
Of your and other CSC's belong to the same Group (OXM), it will always use your CSC.
Will you receive updates? That depends. If per say you flashed EUX that may be XXX1, and they release XXX2 for ILO, then no, you wont.

Question Need advice for the G998U/DS and living in France

Hi guys,
I need advice for the s21 Ultra that i bought on Rakuten. In the description the seller said it was an international/US version and at this time I didn't know that it could cause problems knowing that I live in France. I have the G998U/DS version
For now the phone is working perfectly. I don't have all the problem i can see in other thread like the broken GPS, a poor network, wallet broken etc. Everithing is ok.
But i need advice for the last update with Android 13. Actually i get the Android 12. And of course the phone does not offer me any updates. I know this is because i have a US version and i live in France.
So question 1 : Do you think I will eventually get the update in the future ?
Question 2 : If I install the update by flashing the phone, won't I have all the problems that others have with this us version and living in France ?
Thanks for your support fox.

Hi,
If everything is working out of the box, then you shouldn't worry much. It's always better to install the update via OTA. It doesn't matter where you live/use the device, as long as there's an update for your device (Snapdragron chipset and CSC), it should automatically show up. If you want to install the update manually, then it's better to download the official update via Frija and install the update via Odin.
Hi,
Thanks a lot for your answer. It help me a lot.
About the update, i read everywhere that where we live/use the device is impact the update. For now i don't have any update that show up. I am in Android 12 and i should have the android 13 update.
Lot of people said that i probably never had the update because it's an import us version and live in France.
What about that ? Do you thinks i will get the update in the future ?
Thanks again
It seems you are on a March update. I have a feeling your device's was a locked device which was then unlocked...I could be wrong through...https://samfrew.com/model/SM-G998U/ Here's what I could pull up regarding your device's update. You need to careful on which file you download as I don't see any OXM ROMs for US devices...they are provided by carriers.
Ok,
I think in my case, update will not be possible. I'll stay in Andoird 12 until next phone. Never buy again in Rakuten ahah.
Thanks for all your help.

Just try and not working but that was a good idea
When i chek on Frija, he give me this :
What do you think about this update ?
Edit : this firmware contains these files
If you are sure of the CSC, go ahead. The reason is yours is not OXM rom so you have to be extremely careful when choosing the files.

Ok, thanks, i think i'll do the update.
To be sure, you mention a OXM ROM but i can see that i have o OYN rom like you see in this screen :
I really can't place the device's region. There's no region called GCF in Samfrew. I feel it's a subset of another region. Dunno
Finally I did not dare to flash my phone, I am too afraid that I can not use it anymore
Anyway, thank you very much for your help
