Question Change S21 Ultra 5G CSC "Region Code" (Debranding) - Samsung Galaxy S21 Ultra

Hello there!
I really really need help!
I have one S21 Ultra 5G bought from Spain and I am Portuguese. The CSC region code of my phone is ATL, from Vodafone Spain.
Everytime I power up my phone It installs parasite APPS like "Mi Vodafone" "Vodafone TV" and "Dreamlab".
I fashed several time with Odin. I tried the default spanish ROM, "PHE". I tried the portuguese one as well, "TPH". It flashes sucessfully but when the phone power up it's always in spanish as default and install those apps automatically.
The software build changes everytime I flash a new ROM, but when I go to Software Information, in Service Provider Software Version it always says "ATL" (Vodafone Spain).
I really have to debrand this.
Can anyone help?
Thanks in advance.

It should be a Multi-CSC Device, try this.

Rebrand honor 9 lite from chinese frimware to Asian/Europe

Hi, I have purchased honor 9 lite mobile in China, it contains Chinese firmware (LLD-AL00). Google apps are not working, I am able to install apps from hiapp or through apk however after installation apps are not getting opened, so I want to rebrand to Asian (Indian) version (LLD-AL10). Can any one help me in re-branding phone?
Hi, I did have same probelm as you before, you may install a gms installer to activate google account as well as google play, as I'm a junior user so ca n not post link to you, you can search following keyword " 應用匯 gms 安裝器 " , it 's a 55M apk file, current version is 1.2
I believe final solution would be install a india rom to replace it, awaiting other fan to update if resource is available.

c185 firmwares always support google apps.
For flashing I plan to use the tool in this thread:
https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
Read it carefully, it has been used to flash several Huawei devices.
But so far I didn't get the oeminfo of this firmware so can't flash it because my device is from different region.
If you want to try do it at your own risk.
Thank you.
Hello,
I would like to change my phone from LLD-AL10 to European firmware, so I'm interested is there a way to use zip file from this thread https://forum.xda-developers.com/9-lite/development/honor-9-lite-update-zip-lld-l31-8-0-0-t3767781 and can I simply put this file on my phone and run update or it's not that simple ... I'm new to this and for now I've managed to unlock bootloader following video tutorial from another thread.
Thanks
I'm still searching how to re brand phone to Europe version, so apparently I need something called OEM info, so is it available for honor 9 lite to download from somewhere?
Still the same for me. Buy a LLD-AL10 version, with no B20 band (800mhz). Is it possible to install LLD-L31 rom (stock) ? And does anybody know if it the same hardware (to have B20) ?
Best regards
seb
Hello,
Does anybody knows if I use Firmware Findert and download latest OTA update for european version (there are three files - update.zip, update_data_public.zip and update_LLD-L31A_hw_eu.zip), can I use these filese somehow to rebrand my phone or do I risk to brick my phone if I force these update to install?
Thanks
I’m also want to know how to flash from chineses rom to India or Europe version.
Mind is LLD-AL00 8.0.0.163(C00)
Why not install a generic AOSP instead of using firmware from a different region?. Honor 9 Lite is Project Treble supported. As advertised on XDA Features, AOSP brings out more juice from the device. This is just a recommendation as I haven't tried it yet, but it is on my to do list after the return period for my unit lapses.

Hi there
Thanks for you advice.
I want to use different regions because China version didn’t have google services and so many useless applications that I can’t remove.
Thanks
Paul
PS: I just read some aosp articles around here, seems it still have some unstable issues like camera and battery, so i’m still going after the original rom.
In fact, what kind of international version is he using instead of the China versions rom in this video? https://youtu.be/AyBX1YoHtMc

There seems to be no issue with the camera on AOSP, it's just that battery suffers a bit compared to stock EMUI. Again, this is based on the XDA review, so I cannot really vouch on how the AOSP-GSI performs on Honor 9 Lite. But if you're really looking to flash stock ROM from another location, there's no harm done in trying this one first to see if it is to your liking.
As for flashing firmware from other regions, read here (google translated). It's an alternative site I use to supplement the info I obtain here in XDA.

How to Downgrade to UI 1.0 or Flash Stock Rom

Hello all,
I have Realme X50 5G RMX2051.
Unfortunately I upgraded to UI 2.0 and now I cannot use the Android Auto.
So I want to downgrade, but here is no official file.
Could you please help me with a solution?
How can I return to stock ROM, or change to EU ROM?
Thank you!

Hello, I cannot answer this question. If you tell me where to look I can tell you. Do you know how I can change the ROM to the global one? Or maybe to downgrade manually, because Realme does not have a file for downgrade of this model.
Hi, I got RMX2051 for a while, and still find ways to change the ROM version to EU.
But unfortunetely, Realme locks everything on this phone, I think that's the reason why there's almost no resources here.
By the way, if you just wanna use Android Auto, maybe you'd install it through APK file.

Would you mind to post the screen shot or connect condition here ?
It may help to find out the problem.
Attached is the screen
I found Realme X50 5G (Realme UI 1.0) stock ROM here.
But, it shown in Chinese Simplified...
And here is the tutorial from OPPO ColorOS community. (It's the same Recovery with Realme.)
I'd did a downgrade UI procedure once few months ago, but failed, because the Recovery is going to check the version of Realme UI, whether it was older than installed.
Anyway, if you'd decide to do this, please do a completely backup of your data first.
May this help you, and good luck !

Can't change the CSC for my SE20 FE. It's currently on OXM-O2U. What I've tried so far:
1. code *#272*IMEI number#
2. Flash other firmware with Odin with BL locked
3. Flash other firmware with Odin with BL unlocked
Is there another way?
