Change CSC? - Samsung Galaxy S10 Questions & Answers

Is it safe to change the CSC so we can use a Samsung image that's less bloated? My version has O2 apps installed and I'd rather reclaim that space for something else, or at least not have to look at it.
Change CSC on Samsung Devices | Guide | iHax
Looking for a way to change CSC/Country Specific Code on your Samsung Galaxy device? Here's a quick guide on how to do it easily.
ihax.io

I don't know about other regions, but in the USA region, I beleive the SIM card will set the CSC for you, and not allow it to change. In some cases, even that doesn't work properly (I had to return a phone because it wouldn't switch). Maybe you have more control in other regions or with Exynos phones...

Just tried the key combo and no dice, got a message that said 'that function is not supported' or something like that. I asked a question elsewhere here - what would happen if I were to just flash a different Android 12 firmware version on this phone? Right now, the phone is O2U, would I brick if I used XAA (US)?

I don't know what key combo you're talking about. As I mentioned, in the USA region, the SIM determines the CSC. What type of phone do you have (Exynos vs Snapdragon) as this could affect things as well?
If you flash a snapdragon ROM onto an Exynos phone, I imagine you're going to have problems. I don't know if that bricks it, but I wouldn't be surprised if it does.

Yoooooo I'm going through same issue. Look you can flash any firmware Purdy much as long as the binaries are the same im trying to root a galaxy a13 5g from MetroPCS that only has two months activation in and its beating my ass. I was able to do some kinda unlock on it coz now it says device is corrupted dm-verity can't be trusted but I still don't have oem unlock displayed in developer options I've flashed t-mobile,Verizon,MetroPCS, and now I'm on Canadian firmware which is supposed to be unbranded but because MetroPCS has the network lock on it it hasn't mattered what I've flashed because I even had it XAA by flashing the a5150 csc tar file trying to root this funding piece of suit phone but to no avail.unless I get the network unlock icant get the bootloader unlock option,tried vbmeta image no verity no force encrypt every Magisk version boot image patched even tried different device with same chip and set up... impossible broski if you phone is network unlocked and you are able to unlock bootloader so you can bypass vaultkeeper/avb/secureboot/vbmeta/dmverity/prism.img....etc etc etc and with root access only then can you change and/or modify any part of a samsung device as far as my knowledge and experience goes

CSC Change

Hi everyone,
I've purchased a Korean Galaxy Note 8 (SM-N950N) and rooted it with TWRP and SuperSu. Now I want to change CSC to Vietnam.
I already download 2 stock firmwares (Korean and Vietnamese).
Can you please guide me for next steps with Odin?
just go grab the S8 CSC changer and use that. All we have to do is add 1 line in one of it's scripts so that it will run on a device with 'greatlte' in the name.

It seems that this CSC Selection file did not work for me even I already updated the script file META-INF/com/google/android/updater-script with this code:
getprop("ro.product.device") == "greatlte" || getprop("ro.build.product") == "greatlte" || getprop("ro.product.name") == "greatlte" ||
When I flashed zip file I got error no digest file found
I have this problem could not find any specific answer so far. I'm from UK with an international Note 8 (N950F) unlocked and want to use it with THREE, especially from the wi-fi calling. So, downloaded THREE firmware and after extraction, I got CSC and HOME_CSC among others. First, through ODIN installed HOME_CSC after reboot could not notice any difference at all, the mobile seems the same so decided to install the CSC which obviously wipe the Note. The same, nothing different on the phone. Lastly, I installed everything (AP, BL, CP, CSC) only that way I got Wi-FI calling but also many apps from THREE ( Deezer, Three, Three likes, Ebay, Amazon Underground, Prime video, Amazon MDIP, Operator Settings) and a horrible start-up boot logo and so on. Despite I got Wi-Fi calling I got more stuff and I am not happy at all. Thinking seriously to go back to the international version I had. Does anyone know why after changing the CSC was not any difference in my Note?
Find attached two pictures, first one shows the wi-fi calling option under Contacts-Settings using THREE firmware, and the other one is from the UK international firmware where wi-fi calling option is not there.
Khoanb1, Kett_Traveler modified the S8 CSC Changer zip to work for the Note 8 but only added the USA CSC to it because that's what he needed. I've since took his zip and added the Canadian Multi-CSC (XAC) for myself and the European Multi-CSC (DBT) for you. The European Multi-CSC (DBT) contains the Vietnam CSC (XXV). Download the zip from MEGA here and install it with TWRP. When it asks you which CSC to install, choose DBT, then choose XXV in the next screen to select your Vietnam CSC. Make sure to select XXV and not keep it at the default of DBT at the 2nd menu.
I've successfully used this zip to change my CSC to the Canadian one. Note that after the CSC change, your phone will factory reset itself and wipe all your data (if I remember correctly). So make sure to backup externally first if needed. After a restart, your phone will boot up with the proper boot animation for your CSC and you'll have all your carrier-specific features. For me, changing my CSC allowed me to connect to LTE networks which was not possible before (I was limited to 4G speeds instead). Also, the Korean apps that came with the phone are preloaded onto our system partition, so you have to delete them from /system/apps or through Titanium Backup. You can also freeze them if you prefer.
Note: I haven't tested the install with the XXV CSC so test it and tell me if it works.

Hi peacey8,
Thank you very much for your effort and your thorough guidance. Your zipped file worked very well for my device and now I could have XXV CSC code in my Galaxy Note 8.
I can see some big changes:
1. boot logo is the same with Note 8 devices distributed in Vietnam
2. some apps were installed by default like these devices
3. Samsung Pay can recognise Vietnamese network providers (but I could not still use it because my device was rooted). If you have any idea about it, please let me know.
Great! I'm glad it worked. Unfortunately, Samsung Pay will not work because Knox was tripped. Android Pay still works though if you use Magisk root with Magisk Hide.
Right now there is no solution to Samsung Pay with root. In the future there could be some solution. I'm sure some creative person will come up with something eventually.

Hi peacey8,
Thank you for your explaination. I have another question:
What will happen if I flash all tar files in the Vietnamese stock firmware to my Korean Note 8?
Will I get the CSC code like devices distributed in Vietnam? And will Odin allow me to do this?

Honestly I'm not sure if it's impossible. I'll let someone more knowledgeable than me answer that question. However the Korean Note 8 and the Vietnamese Note 8 are both running on the Exynos SoC, so it might be possible to switch firmwares with a lot of hard work and many problems. For one, the devices have different storage capacities and so will have different PIT files (the file that determines which tar image file goes where and how big it should be). Another issue is the bootloader (the most basic, low-level software of the phone that talks to the hardware to start your phone up) is different for the Korean and European models, so you can't flash the Vietnamese BL file on the Korean model. It would brick the phone if you did.
So in short, no you can't flash a different firmware. But, why do you need to? What's wrong with the current solution of switching CSCs that you just did? Is there still a feature you are missing?

i've used a similar file for the S8+ and my phone rebooted with a new CSC and the message "Android is updgrading"... but it did not wipe my phone.

It's only a question because I'm so confused if I can totally convert my Korean device to Vietnamese one.
You are right, so dangerous to replace bootloader even I already created backup for all partitions.

Hi Khoanb1,
Luckily i found your thread up here, i'm a clueless Vietnamese when it come to rooting phone and other related things. I also bought an KR Galaxy Note 8 lately and have been wondered since then. Is there any other feature that missing on an KR note 8 to a distributed VN note 8?
Would you be so kind to instruct me install them just like you did? im a total noob here.
If you dont mind i can ask for your social media account so we can discuss further.

Hi lluvias91,
I already sent you a private message including my fb account, let's start our converstion about this topic
do you know guys if a packed Note 8 Eng Boot for Exynos variant (SM-N950F) is available ?
tengo el inconveniente con el n950F Exynos sin interruptor de desbloqueo OEM Ayuda
I have the N950F Exynos phone and want to flash the US Mobile CSC to get Wi-Fi calling. I don't have root and am in jail with the no oem unlock issue. I was wondering if I could just flash the CSC from the complete N950U firmware using ODIN. Or can you not mix the F firmware files with the U versions?
I saw the zip file to do the same but it requires root and TWRP to flash.
Not sure I like this phone being locked down. Very frustrating not being able to just root and install a working ROM without having to wait 7 days!
Thanks
In download mode. My carrier id is blank. How do i add the id back?
Hi guys
I buy mine in Morocco N950F Dual Sim (Exact version : SM-N950FZDDMWD).
My phone are not rooted and i dont want to do it for the moment. dont want to increment the knox
I need the french CSC. If i downlaod a french stock firmware N950F and install it with Odin.
It will work without loosing my garante and continue to use samsung Pay ?
Sorry for my bad english
thanks in advance

S20 FE 5G csc change

I am pretty new to Samsung's and their csc system.
I have an Australian SN-G781B with OPS csc (Australian carrier)
Just wondering if its possible to change csc to XSA (generic Australian region) to ensure I get more timely updates that won't require carrier testing bs.

flashing a CSC is super easy. put your phone in DL mode, fire up Odin, load the file and flash the HOME_CSC, not the CSC. HOME_CSC will allow you to flash firmware without factory resetting it. sammobile.com/firmwares to get the FW you need and be sure to use either SamFirm or.... god dangit... i cant ever remember the other programs name. Anyways, SamFirm allows you download the several GB file literally 5x faster and its a 100% trusted .exe. Anyways, get the U1 version of the firmware and flash it, boom... unlocked phone. Might need patched Odin to get around the phones security that usually blocks firmware flashes like these
The question would be if samkey software supports changing of S20 FE 5G's CSC to other regions (e.g. THL for call recording)
If someone finds a CSC setting, flash-able to the US unlocked S20 FE, which enables eSIM and call recording, yet doesn't impact the available 3G/4G/5G bands, please share the info. Thanks.
I just did a successful CSC change on my USA Unlocked S20 FE 5G without wiping the phone, maybe the info can help you. See my new thread: https://forum.xda-developers.com/galaxy-s20-fe/help/successfully-forced-october-update-t4183325
However, you may need to do your own research on the proper CSC to use in your region. I simply wanted to swap my CSC to XAA so I could force an update is all.
Dont bother as I have xsa and have not received any updates yet.

I don't have the device (yet?), sill trying to decide if i want to pull the trigger on it, or get Pixel 5 instead. The eSIM is one heck of a convenience feature when traveling, and i'd really want to know if i can get it working BEFORE actually paying for the device. Right now, sadly, i assume a "no" as an answer on that

Correct, I have the US unlocked version and trying to activate an eSIM from US Mobile for a trip to Asia soon. So far, no luck. For whatever reason, Samsung is disabling this feature in the US for now....

Google it on the original S20 series, and you'll see the same story. For example, here - US Unlocked Version ESIM Update? - Samsung Community - 1147639. Guess we can spell the "for now" in the quote above as "for good".

How To Guide [GUIDE] How To Flash Official Samsung Unlocked BloatFree Firmware

Did you just get your shiny new S21 Ultra? And the first thing you noticed is tons of preloaded carrier apps that can't be deleted? This is how to fix that.
Convert your phone into the one that would come from Samsung directly with a simple firmware flash!
BACK UP YOUR PHONE! ALL DATA WILL LIKELY BE WIPED!
You will need an SM-G998U/U1/W
Computer running Windows
USB-C Cable for your PC to Phone
This is only for SM-G998U/U1/W
Step 1:
Download the ROM of your choice. The firmware number does NOT need to match your phone, as long as you have an SM-G998U/U1/W
From each link, click the latest firmware in the list (what ever the top one is) and on the page that loads, click the blue button that says "Download from website"
(You can only download one in a 24 hour period so choose U1 or W wisely)
SM-G998U1 (U1 is unlocked, no carrier bloat, US radio bands)
SM-G998W (W is unlocked, no carrier bloat, Canadian radio bands)
The only main difference between the two is the Canadian W Firmware supports all radio bands aside from (n260, n261), the file size is a little bigger and will take up a fractionally larger amount of space on your phone as a result of also including all CSC's, but will allow your device to connect to any tower frequency with the correct SIM.
The U1 Firmware supports all US bands and works across all Canadian carriers, but does not have any Carrier CSC's as a result of the smaller file size.
Thanks to @milan03 for the info
Best measure is to use the W Firmware as it will be supported, but if you are positive of your carrier will work and bands are the same as US carriers, use the U1 to save some space.
Step 2:
Download Odin 3.14.4 and Samsung USB Drivers
Step 3:
Extract all of the .zip files that you have downloaded, and install the Samsung USB Driver
Step 4:
On your S21 Ultra, enter download mode by turning the phone completely off.
Once the phone is off, hold the volume up AND down at the same time, and without letting go of those buttons, plug a USB cable in from the computer to the phone
Do not let go of the volume buttons until the Download Mode screen is displayed.
Step 5:
Open Odin and make sure the S21 Ultra comes up as one of the COM ports
If it doesn't try rebooting your computer, and then connect your phone again
Step 6:
Click the BL Button, and select the BL file you extracted from the Firmware .zip
Click the AP Button, and select the AP file (This will take awhile, do not touch anything, don't even click your mouse or try to do anything else on your computer, it can crash, just wait, make a coffee or something, because depending on your computer specs, it can take up to 5 minutes to load that file
Click CP and add the CP file
Now this last part here, you have a choice, however I strongly recommend you do not choose the second option at this time, however you CAN, but you might face stability issues.
When clicking CSC, you can EITHER add the CSC file, which is what I recommend, OR you can add the HOME_CSC file.
The differences between these files is that the CSC file will wipe your phone, but this is recommended, because when you are switching firmware's from a different carrier build, which we are right now, you want to delete anything left over that could conflict with the new firmware being flashed, however, you CAN flash HOME_CSC which will keep all of your user data on the phone, but this could leave old firmware files behind that could cause stability issues with your phone, crashes, force close apps, or even boot loops.
It's recommended to ONLY use HOME_CSC when you are UPGRADING on the same build (eg, if you are on SM-G998W and UPGRADING to another SM-G998W firmware)
So if you are going from U/U1 to W, it's recommended to use CSC, if you are going from W to W, Home_CSC should be fine, if you are going from W to U1, you should use CSC.
Step 7:
Once you have made your choice of either CSC or HOME_CSC, you can now click Start and it will start flashing the new firmware.
This process will take a fair amount of time, go relax and enjoy that coffee you made while the AP file was loading.
Once the flash is done, it will say Pass in green, and your phone will reboot automatically into your new official carrier bloat free firmware.
If you picked CSC, you can now setup your phone just like a new phone and restore your backup, if you picked HOME_CSC, you should be at your lock screen, and the phone is ready to use.
Congratulation, you are now on the Official Samsung Firmware with no carrier bloat as if you bought the phone directly from Samsung.
Troubleshooting:
If you used CSC and the phone did not pass and says FAIL, try the flash again with HOME_CSC, once the flash passes, you should be back at the lock screen, go to settings, search for reset, and do a factory reset, wipe all data because something did not flash correctly the first time so you need to wipe the phone after the successful flash to guarantee no stability issues.
If you used HOME_CSC and the phone did not pass, use CSC and the phone will be wiped when it flashes, and you need to set up your phone like new and restore your backup during the setup screen.
If it still fails to flash both CSC and HOME_CSC, Download Mode probably timed out from your computer taking too long, at which point, you can try doing Step 6 BEFORE Step 5.
Turn your phone off completely, load all of the files into Odin, THEN enter Download Mode and immediately click Start to start the flash. This will give you a little more time for your computer to make the flash and hopefully download mode will not timeout, if it still fails, try a faster computer or a different/shorter USB cable.
If you are with Bell in Canada and you did not get the pre-order bundle promo E-voucher prompt from Samsung Members App, flashing the SM-G998W firmware linked above will fix this and you can redeem your e-voucher and get your headphones and smart tag.
This is a video I made on the S20 Ultra for flashing One UI 3.0 Beta/Stable, however the process is identical, just use the files from here instead of the ones linked in the video description
I will be replacing this video with a dedicated S21 tutorial once I have have finishing editing the new video, but for now this will give you an idea of how it works until 5:30 in the video, after that it's mostly related to One UI 3.0 Beta/Stable for the S20 so there's no need to watch further than that as the S21 would be done by that point in the video.
Thank you sir.
So will this trip KNOX? My phone should get here next week (AT&T), and one of the first things I always want to do is get rid of the bloat.

No problem with KNOX.
But majority of bloatwares are issued of CSC carrier brand and it is impossible to change csc without root or using samkey...
So this firmware will be like other versions with same samsung apps unless I'm wrong.
Thanks for the guide.
If I may, I'd like to post a correction on the state of the supported frequency bands on Canadian and the US firmware:
- The U1 firmware doesn't only support T-Mobile bands, it also fully supports AT&T and Verizon frequency bands, which includes their unique LTE carrier aggregation combinations as well as the 5G non-standalone combinations with n5 and mmWave. That's in addition to T-Mobile's combos with n71 and n41, in both non-standalone and standalone environment.
- At the same time the Canadian W firmware doesn't support all 5G bands, it completely disables mmWave (n260, n261), which means the US devices with this firmware won't be able to access this super-fast flavor of 5G on any US network. It also doesn't fully support all US 5G non-standalone combinations in FR1 (Sub-6 GHz) range.
Thanks again.

If you're running a multi csc firmware (the one's linked above) you can change your csc by opening the phone app and dialing *#272*YOUR IMEI NUMBER# and from there you can pick the firmware CSC and carrier CSC to be whatever preinstalled apps you want. The W firmware has all of the preinstalled which is why the file size is larger.
As for the Samsung bloat, they all come with it, but a lot of these should be able to be removed using ADB without root.
There are some ADB scripts around that some skilled people wrote for removing bloat apps in bulk through ADB without root.

I have a B/DS version, this manipulation unfortunately does not work on mine
Hello!
Thank for you posting this @bANONYMOUS. Question if I buy the the U1 model can I flash the W firmware? My father is in Canada and I'm getting an early Bday present for him. Making sure when he gets it, that it will have the correct bands for Rogers!
Is there any qualcomm firmware that has an FM radio app?
I purchased from the US and flashed the XAC firmware. The final result was XAC/XAC/XAA is that correct? I thought all blocs would be XAC.
Also, I wasn't sure if repartition should be checked or not so I unchecked it.
No VOLTE or WIFI calling on koodo.
I bricked my device today so I'm trying to flash stock OS.
I started flashing it in odin, but it seems it gets stuck on "<ID:0/010> vbmeta.img" for few minutes.
Not sure what is causing it, does anyone have any ideas?
Just tried this with u1. Failed each time
I'm trying to flash u1 onto TMB device. Keep getting failing with sha256 is invalid. Is there a modified odin 3.14.4 yet?

I got a VZW S21 ultra and was thinking of doing this. Do all of the Verizon features work, like wifi calling, hd voice, rcs? and unlocked features like caller id, samsung cloud, call and text on other devices?

Wi-Fi calling in volte work. Samsung caller id it there and I was able to configure it. Cloud was as well. Call and text is and I configured it but my tablet does not support it yet.

Well, based on what my unlocked note 9 has:
Under the phone app settings there should be a setting for caller id and spam protection
Under system settings in the accounts and backup section there is should be samsung cloud,
Under system settings in the connections section there should be call and messages continuity.
These are all options I have on my unlocked note 9, but not on VZW FW S21 Ultra

Samsung SM-925A Updates and/or Custom ROM

I received a free Samsung S6 Edge from some friends. The phone had a busted battery which I fixed. The phone is still on the original 5.1.1 that the phone was released with.
When I try to do updates it says DM initialization not ready. Check network or SIM card. When I received the phone I was told it doesn't work with cell service. I checked to make sure and it definitely doesn't. There are no options for cell service in settings or the drop-down menu. This phone is missing IMEI numbers, IMEISV numbers, and baseband versions too. The only way I found out the IMEI number was it was printed on the back of the phone.
I am fairly certain the problems are software-based and not the motherboard but I don't know enough about phones to be sure. Do you guys know? I also want to remove AT&T from the phone to install a custom ROM on the device. (There is no OEM unlock in the developer options) Can I flash SM-925F firmware on the device to make it factory unlocked or will this brick the device? Will flashing the original SM-925A firmware fix the problems with the device? Please let me know if you need any more information to answer my question.
I found this: //G925A\\ Nougat 7.0.1 Latest Stock ATT Odin files G925AUCS7ERC1 | XDA Developers Forums (xda-developers.com) Should I flash this on my device? Will it fix any of the problems I had on it?
Can I flash the SM-925F firmware? Is the hardware of the factory unlocked phone and AT&T versions the same or will it brick this phone if I flash it?
Since the phone is AT&T you'll have to go through AT&T for the unlock codes before you can flash anything other than an AT&T ROM. To my knowledge there are no custom ROMS for the S6 Edge, but I could be mistaken.

I know this phone is old news however, I actually have the S6 and S7 edge lying around and so i got bored lol...here is my dilemma; Evidently the phone (S6 Edge G925A) had an abnormal factory reset, which is a load of BS, and now I can not get that security detail, which you know calling Samsung always ends to NO AVAIL!! I have flashed with Odin the firmware that my device is on the ERC1 firmware and still I get stuck @abnormal reset. I've searched numerous sites, different forums and still to no avail. Something told me inside that you was the man to drop a line to, any leads or info will be more than appreciated brother...Thanks for your time....
PSSS....
I got my unlock code from AT&T some time ago but the code is 16 digits long and code only takes 8 digits, and of course to hear AT&T tell it, " I simply must not putting the code in correctly"...lmao

SM973u update ?

Hello,
Forgive these noob questions.
I live in France and I bought a galaxy S10.
It happens to be a US model: G973u
I installed android 12 by flashing G973USQU6HULD, G973UOYN6HULD carrier unknow (DSH)
It stays with the T-mobile overlay
1 Can I flash it with firmware for G973F?
2 Otherwise, if I flash with USA carrier (USC) will this overlay disappear?
3 In this case should I flash everything or just the CEC file?
Thank you
No, you cannot flash with 973F, as that phone has different hardware (Exynos CPU versus Snapdragon).
You can try a different USA carrier, but I don't know if it will be very different. I don't know what "overlay" you're talking about, but many carriers do various things to brand the device, and I'm not sure which ones do what.
You may consider flashing with U1 firmware, which is the "unlocked" version. In the US, this then identifies which carrier you are on, and then activates features specific to that carrier when it sees the correct SIM card. Since you're not going to have a US carrier SIM, it should stay in "unknown" mode (XAA). I just helped another user in Europe with an update for his phone, that happens to be stuck in a similar state. He used an ATT U-ROM, because that's what he already had... I don't know if he had this "overlay" you're talking about.
You could even see if there is a carrier that does match what you have in France, and see if you can find a ROM for that. There is a decent list of CSC codes here: https://www.droidviews.com/how-to-change-csc-in-samsung-galaxy-phones/
I'm not sure what "CEC" file you are talking about on your #3 question.
Hi Schwinn
Thank you for your answer
I wanted to write CSC not CEC
In overlays, I was talking about T-mobile's splash screen and non-uninstallable apps.
Pardon my English
Hi
I am the other european guy with the G973U ATT. I dont have any overlays or ATT Bloatware installed, even though I dont have a U1 software. How is the flashed software Version running on your device? How is the battery life? Did it change after the flashing? Im curious cause I also have the Snapdragon model of the s10 and the battery life is not bad but i expected more for Snapdragon.
Hi Lessy,
It's a new equipment bought at professional seller in Rakuten.com I flashed it via ott to obtain android 12 and changed the firmware with 'unknow carrier' but it didn't made any difference. I will try with 'USA' carrier
@Fast_Lessy You made a good point on your other thread... that maybe the ATT version is causing you the issue. The theory is that if the carrier isn't recognized, it could be working harder to maintain a connection or something. Unfortunately, for you in Switzerland, the S10 is normally the Exynos, so the ROMs that support you officially are going to be for that CPU (G973F variant of the hardware). So, you can't use those ROMs on the USA version (Snapdragon CPU).
I think you may consider trying the XAA version of the ROM, as this may be more flexible to work with your carrier. In the USA, this version will "adapt" to the SIM as needed. In your case, it can't adapt to your carrier, because it doesn't know how to do that, but maybe it would remain more "world compatible"? I'm just guessing...
Assuming you want to try that, you'd change to the U1 version (G973U1) and get the XAA ROM. For example, these: https://samfw.com/firmware/SM-G973U1/XAA
I'd suggest sticking to A11, but you can certainly try A12 if you want. However, note that you might want to wipe the phone before doing this, because it may be different from the "U" version you have now.
Note, the U1 is what I have on my phone now. This shows up as Provider Version SAOMC_SM-G975U1_OYM_TFN_RR_0009 (I'm on an S10+, and I'm on CSC TFN/TFN/SPR. The OYM means it's the "XAA"... not sure why this happens, but that's what I have heard. OYN means it's the multi-CSC ROM for USA, but on the "U" version, instead of U1.
As before, the risk is yours... please don't blame me if things don't work out, but I will help as much as I can! And always backup anything important to you before doing anything.
I tried to flash G973U1 without success (SHA error) so I flashed android 12 with "USC " CSC for G973U after a total wipe.

The phone works but I still have the red T-mobile start image and the T-mobile application.
It seems that all firmware are like this. I stop searching
If you did an upgrade install with ODIN, yes that will likely happen since upgrade won't "remove" the previous settings and setup. You would have to try a clean "refurbish" install, and that might clean that out.
Of course, I assume you don't have a TMO SIM card either, correct?
Yes I installed with odin after wipe user and cache in recovery mode. I have a SFR (french provider) card.
