Hi, i have a stock firmware AUT (switzerland) installed, but if i insert swisscom (SWC) sim, does it automatically change AUT to SWC? Thanks
Using SIM of another country does change CSC, if it didn't, simply go to recovery mode and it shall apply the new CSC code.
However, it's not guaranteed which CSC will it convert to, as there were reports of a different applied CSC code than the country's one.
I found patched Odin 3B.
You can reflash rom for any possible region and 3 fields in CSC will be changed. Last one no.

Well, i dont want to change csc code, but if i insert the sim card of swisscom (still switzerland) does it still change csc code? (Without wiping) Or does it stay in AUT?

It won't wipe anything unless you manually change CSC using dial code or any other way to trigger the change.
Using another country's SIM does change CSC (after a reboot). You sound like you don't want to change CSC .. right?

And.. you said using another countrys sim does change csc (after a reboot), but does it change csc if i insert the sim card of same country (but another carrier)?

The Operating System has a list of every SIM carrier out there. The SIM itself does tell the phone which country it belongs to.
Using different carriers on the se device, in the same country does not trigger CSC change. The trigger only starts when another country is reported to the phone.
If you want to skip CSC change, there may be two ways, either root your device, or disable the system apps responsible for it.

Sorry but one more time..... so if i use the sim of different country, then csc changes, but if i insert the swiss sim card (after changing csc), do i have swiss csc code again?

You receive a brand new phone >> The phone asks you to insert the SIM card and reboot >> You follow >> The phone applies the new CSC code respectively for your country >> You simply use your phone as a normal citizen would in that country.
You return back to your country >> You insert your country's SIM >> Phone asks you to reboot >> Your original CSC is back.
Thank you so much!!!

Hi guys,
I need your help: I get a Galaxy S9 with active CSC set in SMP (it is an unknown version because it's a sample).
I flashed a multi CSC firmware SM-G960F because I need an ITV (Italy) CSC on it (I want OTA and also Samsung Pay Service).
I don't know why, but when I flash the CSC it set automatically on Germany/DE Status with no chance to change it. The Active CSC remains SMP and CSC Status sets into Germany/DE.
I'm sure I've downloaded from Updato the ITV version of the firmware.
In the past years it was very simple because it need only the correct firmware of your country region to solve the problem. But now with this damn Multi CSC it is impossible!
I tried many ways and guides found here but no one solved the problem.
I wanna change it without rooting the device.
Any suggestions?
Thank you so much in advance

Apparently it's impossible to get around it because of this multi CSC no matter what firmware you flash it will not get rid of the carrier firmware on the phone.
qualcomm 9650ds, flashed a multi csc firmware, a window popped up:
SIM card change Restart your phone to configure the functions compatible with your new SIM card. This will reset the phone to its default settings and delete all data, including files and downloaded applications. NOW NO RESTAB. AND RESTART
After restarting, the correct csc has been read. (probably has something to do with the Sim card)
PS: if chosed now no, the 4g signal bar showed LTE; if yes, the bar showed 4g

For the SM-G9650DS, would you mind sharing which multi-csc firmware did you use exactly? which CSC are you on?
Hi, this is my first post. And im new on this teme of the Multi CSC roms.
I have a question, I get a ROM from SamMobile of my carrier Telcel in Mexico (TCE). I understand that the rom is multi csc, but when I flashed it all the bloatware (that in this case i need, VoLTE is only in my carrier) is from Claro (CHL), and I need it from Telcel. I sent a mail to SamMobile explaining this but they only answered me that the room its ok, the rom is multi CSC.
The CSC version that the system shows me is CHL/CHL/TCE, and I need TCE/TCE/TCE.
Anyone knows what I should do?
From my experience changing firmwares to enable volte, to fully restore csc it's flashing the firmware TCE, download from samfirm app on computer then factory reset from the firmware you have, flash TCE firmware with Odin and this it's the trick you need to have another carrier sim(no telcel) before flash the firmware TCE, wait for boot(don't put an account) when you are on the home screen turn off then enter recovery and factory reset and reboot, here when you swap the Sims, put the telcel sim on it and wait to fully boot and when you see the welcome screen you see a message that say the sim card it's different and need to reset, accept and wait for boot go to settings and check csc and now would be TCE\TCE\TCE

In my quest for fully change the csc without flash twrp and root to lose Knox warranty I ended with some smart guy that say the first two can be changed with flashing firmwares and the last one can only changed with root for that reason if you flash a different firmware region the two changed with the default csc on the multi csc and the last one stay same for example in this case MXO/MXO/TCE and the only way to return all the same it's using other carrier sim card temp until you flash the original firmware and then factory reset and when reboots swap sims putting the original carrier sim card in this particular case telcel

Thank you for your answer! But, let me see if I understood.
1- Put a sim from another carrier.
2- Factory Reset.
3- Flash the phone.
4- Turn on, and configure it.
5- Factory reset (again?)
6- Then put the Telcel SIM, before it starts completely
7- And finaly, in the "Welcome" screen, when the phone shows the message of the sim changed, perform another factory reset.
Let me know if I am right,
Right now I don't have another sim, i think that its rare that someone has another carrier But when I have it ill tell you what happenned

In this particular case try to get original CSC TCE/TCE/TCE
He has CH/CH/TCE
If you wanna recover original CSC you need to have another carrier sim on step 1 and when you flash the original firmware go to recovery amd factory reset from there and when you put reboot in the process of boot you swap sims, put the original carrier, firmware sim

Do you know if the phone must be unlocked? I tried to do it but when I put the other sim, asks me for the carrier unlock code. The phone doesn't show me the message of the sim changed.
I've been some research and I found that Claro is Telcel in the rest of America Latina. Maybe its the reason that shows me Claro.
I tried the CSC secret code *#272*IMEI# and nothing happens, how i know if a ROM would let me do this?

For that only flashing another firmware if you are from Mexico could you install MXO firmware it's the generic Mexican clean version and that you get MXO/MXO/TCE
The last one remains TCE this only can be change with root.

Try download from samfirm it's more fastest download the full firmware it's pc exe.
Do you try the step mention above? With other sim factory reset from recovery and swap sims, when phone boots tells you the sim change and need to reset and then you get TCE/TCE/TCE

Wow thank you! Im downloading it right now at 2.2 mb/s, compared with 100 kb/s of sammobile.
I tried anything and nothing works, I think that the unique solution is try with another OWA roms, I don't know if Telcel and Claro SIM's have similar identifiers and thats why returns me to Claro. Don't you know if there are roms with the csc menu activated?

My phone was originally from att but I unlocked it and now use it on telcel and I want to use VoLTE with telcel. I would like to try the att or movistar firmwares but the problem is that (for what I've read) since the last att update was from like March the bootloader is older (v1) compared to telcel or MXO (v2) so you can't downgrade.
What carrier are you using? And what do you want it to be?

As far I know to get VoLTE on telcel you need to buy phone directly with them, because uses the imei to enable that function

Yes, I thought so too, but the thing is I went to Telcel and asked and the told me that my phone SHOULD have VoLTE but I think that may be associated with my phone number, (since I've had that number for a long time), and not with the IMEI
Hey all,
I was given an S9 (Exynos version, unlocked, SM-960F/DS) that had TWRP installed on it, but was stuck in a boot loop. After messing with it for a while, I stuck it in a drawer and forgot about it until recently, when I pulled it out and decided to just restore it to stock. I downloaded a ROM for that specific model from this site ( https://forum.xda-developers.com/galaxy-s9/how-to/official-firmware-thread-regions-t3765015 ) and flashed it using Odin. This got the device to boot fine to the setup, but it defaulted to German, and rejected any SIM I put in it, even though the phone was originally unlocked. So my question is, now how do I remove the SIM lock again? I'm guessing I'll first have to wait the 7 days for the OEM unlock cooldown to elapse again so I can reinstall TWRP?

What I meant by that was that a friend of mine handed it to me to try to fix after he messed with it in TWRP, getting it stuck bootlooping in the process. He had bought it factory unlocked. I checked the IMEI, it's clean. It's demanding PUKs for any SIM I put in it, even though those SIMs work in other phones; I tried a Ting SIM and a Cricket SIM.

Well the only thing I can think is to flash a stock firmware for the region you are in, pick a carrier firmware to force the CSC change, Multi-CSC that contains Germany will default back to that if that is what the phone's original CSC was, but I doubt CSC is causing this
O2U CSC (United Kingdom) for G960F is a single CSC, flash it using CSC and not HOME_CSC along with the other 3 sections
But it seems to me this was not originally a factory unlocked handset, it was unlocked by an unlocking service and sold as one
If that doesn't work, pay for an unlocking service

Is there a way I can find out what carrier the phone thinks it's locked to, or would I just have to get SIM cards from around the world and try them?
Can I do this without enabling OEM Unlock (so without letting the phone run for 7 days)?

Samsung Phone INFO will tell you the current CSC, but if it defaulted to German either you flashed a German firmware or that is the default CSC
OEM unlock is only needed for custom
Flashing a Multi-CSC ROM such as BTU for United Kingdom will have the greatest chance of it defaulting to it's original CSC
I used that app, and it indeed says the phone's CSC is German, Deutsche Telekom from what I could tell. I tried flashing a number of different FW packages (including the UK and Singapore ones) but it still defaulted to German each time.
I tried going to their unlock page and entering the IMEI, but they have no record of it being sold by them.

Like I said, try flashing a carrier branded firmware like O2U, it cannot default to German if that CSC is not included
Flash using CSC and not HOME_CSC
Sim lock is on its own secure enclave chip, so if this was truly Sim unlocked then it isn't even possible to "relock". Either was unlocked in an unreputable way, or is IMEI blocked as mentioned before.
So I just got time to re-visit this project. I flashed O2U firmware, and it defaulted to English and shows the corresponding CSC. The phone is still locked, and I checked a bunch of IMEI blacklist checkers and each one comes back clean. At this point I accept that the phone is actually locked by a carrier, so I need to instead figure out how to get it unlocked, and to do that I need to figure out what carrier it's locked to. Like I said earlier, I tried entering the IMEI into Deutsche Telekom's unlocking page, and they have no record of them having locked that phone. So how would I go about figuring out what carrier it's locked to? If that information is on its own secure enclave chip, is there any way to read it?
Afaik german providers are forbidden by law to simlock phones for several years already. Problem must be somewhere else.
Try entering the PUK of any SIM if that's what's requested. It should be on the full size SIM, else contact your mobile network operator.
1. Launch your phone’s dialer, and type in the following code, and replace the italics text via your phone’s IMEI number. “*#272*Phone’s IMEI Here#”
2. Your phone will automatically pop up a screen, with some fancy codes all over it. Don’t freak out yet.
3. You will notice some codes with a radio button beside each and every one of it. These are the CSC codes that your galaxy device supports.
4. All you need to do is select the one code that fancies you, and head over back to home.
5. Now, your device will automatically restart, and factory reset itself.

Bad idea.
I did dis using the code with s10+ but aftr csc change from INS to BTU i couldn't go bk to original csc using the same *#272*imei# method. None of d known csc changing methods worked 2 go bk 2 original csc. Combination fwrs also dint work due to Samsung restrictions. Samsung service centre also couldn't fix & then Samsung replaced the phone finally. It ws a nightmare.
same on one of my devices A102U or A505U cantbremember which right now and dont have it on me but it only worked when i had a sprint sim in for some reason then i changed it to gcf then the code no longer worked lol.. so its stuck in gcf as i cannot find another way to change csc and both do not allow flashing combo firmware lol
although its not bad.. itssimilar to using xaa firmware and network info is set automatically with new sim..
i believe it only works on certain csc so have a backup plan if you plan on messin with it
Will changing the region make a difference? Which should I change it to? Will this enable e sim
I have a SM-G985f/DS hybrid version and i am doin *#272*IMEI# to change the csc.
Will changing just the network code make a difference?
UPDATE: I fixed it and now i have a hybrid slot and an esim enabled
Changing the CSC to the region you're in is typically the best option however that may limit carrier calling features. To optimize call features acquiring a device from your service provider is ideal. If your service provider offers eSIM it can be enabled on most Exynos devices.

All I had to do was insert a sim of a region where esim is supported and then factory reset. I backed up my data using smart switch. Now the region is UAE and i have a dual sim option and an esim option.

I'm from Malaysia. i bought the phone at taiwan. Taiwan disable esim. But at Malaysia I have esim option for my telco.
So I can just change the region to Malaysia region?

Just one will be enough. Once you select a csc to change to it will ask if you want to change just the network key. I selected this and it didnt work. If you try the other two option it might work. Whatever you do be sure to make a smart switch backup before you proceed.
Heres what I did: What you need to do is remove the taiwan sim and then with malysian sim in the sim1 slot head into settings and factory reset the phone. Itll take about 10 to 15 minutes for it to reset. Once it does that, it might prompt you that your region has changed and you need to reset your phone. If you accept that your phone eill reset for a second time and once thats done you region csc will be changed and esim will be enabled. Now restore your data from smart switch. Your apps and data will be restored.
please update if it works
Thats how I did it. One tip that I do have is to backup your whatsapp chats frrom the app itself. Smart switch dosent backup app data, only the app. So I lost some of my chats.
Other methods I was reccomended was to use samkey or to flash a completely new firmware. The problem with samkey is that you need to purchase credits and flashing a new ROM moght void your warranty. The method I used is the simplest and will work for sure.
