Debranding Samsung Galaxy s21 - android 11 - possible? - Samsung Galaxy S21 Questions

Hi
Is there any effective method for debranding Galaxy S21 with android 11?
I have CSC from Play (Polish operator) and I would like to upload XEO. I tried odin and samkey and despite the "positive" completion of the operation (both applications say so), the Play brand is still on the phone.
thanks

if your s21 phone has an unlocked exynos variant, you can download the indonesian version with XID csc using frija and clean install with odin, I tried it on the s20. (did i change csc for call record)

1. How can I check if I have "an unlocked exynos variant"?
2. I don't really care about call recording, but rather about removing operator branding. Is it possible?

Hi
If you have a G991B it should be possible to flash any (exynos) rom , even if the phone is carrier lock .
How did you do it ( the flashing), what files did you use , home_csc or csc?

Hi mate
Is hard to say with the information given , that was during samkey installation? did you installed Samsung drivers? for what phone you downloaded it, it seems old, try a newer version

Method to get Andorid 10 on your Note 10 Exynos now!

Hi,
This is one of my first posts so please bare with me. You will need to download a few programs to get this working.
The first is frija. LINK - https://forum.xda-developers.com/attachment.php?attachmentid=4886005&d=1574653611
Above app is not mine all credit to the dev in the link.
Secondly you will need Odin I'm sure you can all source this yourselves.
After downloading and installing frija, open the programme and search for SM-N970F CSC code DBT
Continue to download the firmware and then flash with odin.
Simple method if you cant wait for it to be rolled out in your country.
I am not responsible for your data or devices, follow the steps at your own risk.
This should work for note 10 plus also, just change the model number and keep the csc as DBT
can i keep home csc ?
Not Sure

I did a clean install, in odin i selected wipe in options so formatted all and it installed perfectly. Perhaps use smart switch to backup all your data and then flash if you still have this option available to you.
Thanks... unfortunelly the download of the file from Server is not working...too slow (

What model phone are you using and what network CSC are you going from and to? I went from UK unlocked direct Samsung handset BTU to Germany DBT model SM-N970F. Worked without issue. If you give more details maybe myself or someone else will have the answer.
Odin files version 3.13

unlocked sprint S9+ to romstock samsung

Hello
I have an unlocked S9 + US from the operator Sprint:
model's number: SM-G965U
Version : G965USQU3ARG2
oeprator soft ver: SAOMC_SM-G95U_OYN_SPR_00_0089
36514b5658543098

It works perfectly with my french SIM but I want to flash it with an official samsung US rom to eliminate all traces of the sprint rom, could I still use my French and Algerian SIM please? Any risk with a standard flash? Where can I find the stock rom?

dont flash a USA carrier firmware set for it (theyre not ROMs when you flash them in Odin, theyre called firmware). Flash the firmware with a multi CSC, preferably one that contains your needed CSC

that error wont cause any issues other than just plain being super annoying. Each USA carrier has something stupid built into their firmware that causes silly headaches like this. If you get a notif in the pulldown area, you should be able to long press on it and tell android to ignore it. If not, you might just need to find the U1 version of android 10 and flash that on your phone so it doesnt know its a sprint phone anymore. Phone amnesia for lack of a better way to describe it LoL
THX very much but I dont where I can find this U1 version of android 10 for s9+? Last question can I install a french firmware version?

you can install a French version if you like, but the U1 version is the unbranded version and you can just pick whatever language you want upon install. Honestly, i would just flash this https://www.sammobile.com/samsung/g...SM-G965U1/XAS/download/G965U1UEU7DTA5/314795/ by using patched Odin which can be found here https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
THX very after installation I insert my simcard. I have a message like my phone import info from sim card and now no message error and the CSC is XAA, no sign about SPR.
it seems good.

Can You Flash T-Mobile Firmware On An AT&T Samsung Galaxy Tab S7 SM-T878U

I bought an unlocked SM-T878U for AT&T and since the tablet for T-Mobil has the same model number for either provider, can I Flash the firmware for the T-Mobile Tab S7 onto my tablet without any problems? Sorry if this has been asked I searched around for over an hour and didn't find the info I wanted.
Edit: this is the 5G version not the LTE but both are 5G
Thanks
Yes... you can flash firmware from the same model.
T-Mobile and AT&T should be using the same firmware (T878USQU1BUAC).
Your SIM card and device CSC determines what carrier specific apps and features to load.
Thanks for the info mine is using a different version then the one you listed I just don't want to brick a tablet I just paid 500 for...

ATK1 is an older version. Just make sure whatever version you flash is for the same model number. T878U.
It will install without issue... make sure to flash HOME_CSC to keep all of your data, apps, and settings.
Thank you for the info and I didn't know that home CSC would keep all my data... Thank you.

You're welcome.
The rule applies to all Samsung firmware.
Flash CSC_OMC to do a clean install.
Flash Home_CSC to keep your stuff.
That did not work I downloaded the firmware and flashed it and now it just goes to recovery mode and won't even boot up anymore figures this would happen, just the way this year has been going, you have a place I could download a good firmware to just completely nuke it and go back to stock? It was stock before I mean I just tried to put the T-Mobile Version on.
From this site, https://galaxyfirmware.com/model/SM-T878U and I used this build number T878USQU1BUAC
Edit: Edit it did end up finally booting up after doing the app repair function in the recovery and also a factory data reset but still says AT&T only thing that has changed is I now have android 11 lol
I just want to get all the att stuff out so I can use the t-mobile texting and whatnot I can't use that now because of the att junk.
It is like a VIRUS infesting it.
Again thank you for all the help.

Looks like you'll have to manually change you CSC.
This post has some advice on how to get this done.
SM-T978U Odin Firmware Flash
Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but...
forum.xda-developers.com
Also make sure you are using a patched version of Odin when flashing packages... I assumed you know that, but in case not, here is a link to download it... https://www.androidfilehost.com/?fid=1322778262903995077
From all the digging I did. It is not possible as you have to unlock the bootloader to change the CSC. And well I spent over 3 days on this crap to no avail. I just sold my ATT model and bought the tmobile version. So ridiculous that Samsung does not just sell an unlocked version to avoid this hassle. Very annoying.

Android 11 Update for SM-T725 - S5e LTE - Firmware download

Hi guys.
DOWNLOAD LINK
MultCloud | Best Free Multiple Cloud Storage Manager
new.multcloud.com
This is the UK Version of the Android 11 ROM
Have successfully flashed to a my Australian one without issue and retained the unlocked bootloader
I paid a months subscription for SamMobile to get the new OneUI 3.1/Android 11 firmware - I'm running lineage 18.1 but I really miss the Atmos DSP, and HD Netflix, so am going back to stock.
It's a real pain getting Samsung firmware so as soon as it's finished downloading, I'll reupload somewhere, so anyone who wants/needs it can get it easily.

Only preference is please help us to keep XDA neat by not duplicating thread, this is against the rules. Thanks
Uploading now
Will see if I can't brick my device reverting to a stock, different region rom.... (I don't use the LTE functionality so I assume less potential issues)
Well, everything seems ok so far (it's nice being able to use the fingerprint scanner again!) and the bootloader remains unlocked
Got about 1GB left to upload
Updated OP with download link
Thanks mate, updating mine today
You can also download with Samsung Firmware Downloader. Github repo zacharee/SamloaderKotlin. It has a little more than Frija and is cross-platform Windows, Linux and Android. Has anyone heard or seen anything about T720 wi-fi version getting update ?

Hi mate
Native call recording is CSC restricted , some countries do not allow it (by law) maybe UK is one of them.
Two options , change your CSC to one of the countries that allow it ..
Or use an app as i did check it here , lots of settings , works great

Hi,
Thanks for helping, I'm already using that app but would much prefer native as I had on my OnePlus 7t. Is it possible to change csc without flashing/wiping my phone ?

Hi
Yes and no , changing the CSC is not quite as easy as it was , check my reply here in how to change CSC.
Now with the no part of the answer , changing to the desire CSC is only possible if the CSC is available in the current rom you have installed if the CSC you wish is not there then you need to flash a new rom .. wiping may not be necessary if you use home-csc instead of CSC file
First step find out what CSC allows native phone recording , second step see if you have tha CSC available in you installed rom....
