I have a Korean G960N device that has a lot of KT carrier bloatware, so I decided to flash a KOO unbranded Korean firmware, however even after flashing is successful the device still shows KT logo, bloatware, and several KT-related options in the 'Settings' app, as well as KTC in the "about device" option. how do I get rid of this ****.

flash the CSC not the HOME_CSC. The CSC file will factory reset it and remove any remnants of the previous carrier info including bootanimation, splash screen etc etc

I know, and I did, and still shows KTC bloat including logo. I saw other people posting about the problem in other samsung device forums but didn't find an explanation. I wish there was a unified forum for these general samsung issues, so that they'll get the largest amount of attention possible.

can you grab a multi csc and flash it without the sim card in it?

lel, I've been trying to flash an international firmware for 6 months now without success, it's always some damn PIT error, tried everything Patched Odin, with PIT file, without PIT file, with NAND erase, without NAND erase, EVERYTHING, and none of it works, and no one on the internet confirmed that flashing an international G960F firmware on a Korean G960N device actually succeeds. just check my post history to see all the posts I made about the issue.

doesnt surprise me that the F firmware worked on a N device at all. Both are Exynos chipsets, so there isnt really a reason for it to not work. 6 months you say? @AthieN have any ideas?

Either the firmware being flashed is mislabeled, or it's not truly flashing. I've seen where Odin says it was successful, but not really... That could be a whole different set of reasons why it's not working though.
My suggestion is re-download the firmware, from a trusted source and try again.

often times the phone is being told what carrier youre on by the sim card, then if the phone has that carriers CSC in its internal database (in the case of multi-CSC firmware sets) the phone will recognize the carrier and then install the carrier specific crap. I use the U1 firmware and dont have any of the carrier junk that it originally came with. I got it on a Cricket offer and very quickly got rid of all the Cricket junk by flashing the U1 firmware
I successfully changed CSC to KOO on my G960N after it was SKT to do that i had to
- root the device
- install phone info app
- use the tool to change csc
You will have a choice of 4 CSCs choose KOO and install
PS : backup data as it will be erased

Thanks again for this help bro , i already forgot about the csc code changing , only thing who were annoying to me were the SKC blootware and bootanimation
i succefully uninstalled the blootware after rooting and using root uninstaller pro , then about the bootanimation i couldn't find any way to change (even by changing files into system/media/ ) , so i just left it
but good thing you gave us the steps , maybe it will help one guy who is willing to change his CSC code

Do a backup with twrp when you change csc it will erase data and you will loose magisk all you have to do is go back to recovery and restore the backup ( backup only data )
Twrpcan always be installed with odin with or without magisk
Alright bro , thx again for the help !
Hello everyone. So I have a S20 Ultra SM-G988N. Its a Korean variant with a Snapdragon Chipset. It has the option OEM unlock and all so the device is rooted. I also was able to change my CSC without doing a data wipe...
What I did was go into the root of the phone into /ets/imei/mps_code.dat. I opened that file with text editor. For me it came up empty so I added the text "KOO" with a different text editor because the one provided by my Root Explorer wasn't letting me edit it. Once I added that in I restarted my phone. My phone started up, had the regular Samsung Logo. But if course some of the blostware is there.
My big issue is the phone connects to Korean things as in some apps will say my Region is Korean. For example my Weather widget (Samsung App) would only let me pick location by state, or country. I can't choose the town I live in nor does the app knows my correct location. It would say I'm in Bethpage Korea.
So my question is because the SM-G988N has a Snapdragon Chipset, would I be able to Flash an U1 Variant Home CSC Using Odin? This way I have multiple CSCs which I can then use to debloat and get the phone to be like US Version.

if i want to flash in KOO Flash pack, is it necessary to unlock bootloader and root? Is there any way to be able to root without losing Samsung Knox?
Hello,
So I am in France and it seems I won't get Android 10 update until March.
I have seen a lot of contradictory information regarding flashing firmware with different CSC, changing CSC...etc.
SO, is there a way to update to android 10 if I have the Multi CSC ROM, currently set to XEF?
Hi ondris,
You can use SamFirm tool, try to find it on xda, probably you're familiar with it. I've updated my phone, bought originally in Sweden, and I'm using it in Serbia with SEE CSC, you can use also BTU, phone will automatically detect network operator, and you are good to go. Flash it via Odin, steps are also on xda, and what I can tell you as an advice is that when you use Odin and flash CSC, you have CSC and Home CSC file. Regular CSC delete all the data from the phone, and Home CSC will save everything you installed and kept in you phone. I hope this helps you.
Thank you for the tips.
But the thing is i don't want the rom to change the csc by itslef.
I want to either change my crurent csc to one that has been updated to android 10 or flash an android 10 firmware with csc different of mine.
Can I flash SM-G960U US unlocked firmware on my SM-G960W device to get android 10?
Hello to everybody,
I have a Galaxy S9, model SM-G960N and finally the Korean Update to Android 10 arrived, downloaded it from SamMobile (The unbranded version KOO) Flashed it without problems and the phone works as intended. Only it doesn't have KOO as CSC, it has SKC, which has bloatware and it isn't the one I flashed. What gives? Why does it do that, are there any workarounds? Here's what I've tried until now:
Downloaded, and flash numerous times, no result, I don't live in Korea, I don't have a Korean SIM, phone still reports SKC.
Flashing with or without sim card inserted gives the same result.
Can't flash any other CSC, other than Korean ones, Odin spits out an error and it does not even start the flashing process.
Mix and matching different CSC with different firmware's obviously not successful.
Any idea if something can be done about this?
Thank you in advance.

I guess that's the only remaining way, but do you know why it picks SKC instead of KOO, even if the firmware that I'm downloading is KOO.
Korean CSC is a multiCSC even if you download KOO firmware you phone will use SKC that's included in the CSC so there is no different korean csc there's only one that includes the 4 csc codes
i have rooted device but i need multilanguage. ho i can debrand or add orginal languages?

i've to face the same thing mine is KTC but it shows SKC. idk what to do after did that always my device is getting overheat
Ok
I have a Samsung S20 which is unlocked but originally using THREE Network. I have the Original Firmware downloaded already for either VODAFONE or BTU. I also have installed TWRP and MAGISK. I also have Flashed with Up Parim Tar to get rid of the Bootloader Open etc.
What I want to Know is, I want to change the Boot Logo from THREE to either VODAFONE or BTU. I originally Flashed the BTU in the hope it would remove the THREE details but it has not.
I have read a little but thought Id ask here for some help. I have read to use patched ODIN and HOME CSC to keep all my data and settings and flash with either VODAFONE or BTU and it should change the Carrier and keep my settings so just reboot and it will change the details. Or have I got this wrong? Hopefully someone can assist.
What I am aiming for is to change the THREE boot ups, keep root and change to either VODAFONE or BTU, preferably without having to wipe the data but if I do I will have to. Just not sure which CSC to use and procedure to do this. Thanks in advance. . .
I would appreciate if anyone can point me to the right direction. I have 21FE G990U2 from AT&T, It is unlocked by AT&T.
All I need is working T-Mobile firmware or Samsung (no carrier branding) to flash. I tried multiple versions of U, U1 and U3 firmwares (all matching my current Binary -4) but no success.
I just would like to get rid of ATT bloat. I know I can uninstall it via ADB but I rather have firmware clean of it.
Any suggestion please?
Thanks
So am I right to assume that you are looking for a G990U2 TMB firmware with Binary 4, to flash on a G990U2 AT&T phone?
If so, then you can download it from the below link by clicking on "Download Samfw server" (G990U2OYN4EWC3, April 2023 update):

or if I am assuming wrong, can you please correct my understanding? As I do not have any practical hands-on experience with the USA models.

You are correct - I need T-Mobile (or carrier free) so I can utilize full carrier settings.
Thanks for the link, however above link gives an error when opening the page.
Nevertheless I will look for TMB firmware with CSC: G990U2OYN4EWC3 and post an update here
Flashed that and still has AT&T boot logo and all the apps

Well, I am sure that you have flashed by a Factory reset (Flashed CSC, not Home CSC in ODIN). The boot logo can be changed by rooting your device, also bloatware apps can be deleted via ADB command without rooting.. but you already have mentioned that you prefer not to proceed with those processes. So I am out of suggestions, sorry.
Just for my knowledge, after flashing the TMB firmware, now your settings> About phone> software information> service provider software version: 2nd line shows as TMB/ TMB/ AT&T?
(Also corrected the download link in my previous comment anyway).
Yes, you are correct i did flash CSC, not home CSC. Then I reflashed w home CSC but software still says ATT/ATT/ATT.
Moreover on Bootloader screen says "carrier ATT" - I have never seen that before on any Samsung phone that I had. I have no clue how did they lock up device that well. As for removing software via ADB that is not a problem, but ATT locks network selection mode so you cant choose between 5G, LTE, 3G etc..
TMobile in US still supports EDGE and sometimes it comes handy - whereas ATT has only LTE and 5G as they re-farmed EDGE and 3G/HSPA frequencies

I do not get why the CSC can never be changed, even after flashing the complete firmware... must be an ATT thing!
Anyway, to change the csc only, there is another very quick & easy method. It takes only 2/3 minutes; no flash or factory reset is required. You have to download and install a small software "SamFW Tool" on your pc/laptop (may need to disable the antivirus during the download/install process). Once done, connect the phone and enable USB debugging mode. Open the software, under the ADB tab, click Change CSC, from the dropdown list select TMB and click Change. The phone will restart and CSC "Should" change to TMB/TMB/ATT.
Here is the download link for the software:

That did the trick. I have T-Mobile CSC now
Thanks a lot

Great!
But still, that's only one part of the final solution I think. Your target was to replace the complete firmware from ATT to TMB, right? Since the CSC is now changed to TMB, I think you can give it another try via ODIN to install the TMB firmware now (only if you want). I am not confident that it will work now, but still, one last try should not be much of a hassle.
I think that these multi CSC contain all US carrier customizations....When I changed it to TMB it shows TMB/TMB/ATT and loads bootlogo as well as TMobile apps... I guess it is similar as Blackberry used to be back in the days...Depending which carrier SIM used it loaded proper settings from the firmware...
I have flash my METROPCS G990U2 to G990U3,other sim card work fine,but t mobile sim card does not work ,can someone help me?I already change CSC to xxa,but still no internet,I do have sginal bar
