Question KTC To KOO for Korean Variant - Samsung Galaxy S22 Ultra

hey guys , i tried samkey , to change from KTC to KOO , S908N variant
but it did not work , i followed all the steps which is :
Open SamKEY and log in using your shiny new password
enable USB debugging through the developers menu (tap build number in software 7 times)
remove all lock screen security (pin, pattern, fingerprint and face)
Remove your simcard(s) from your phone and connect the USB cable
type your desired CSC in the 'CSC' box
click 'change CSC'
tried 3 times , but no luck , anyone know why ?

Try using SamFw_FRP_Tool_v3.1. It can be downloaded from samfw. com

I already tried samfw before samkey but still not working

KOO, KTC, LUC and SKC are all under the same Multi-CSC and firmware.
Maybe try doing a clean flash without a SIM inserted and use CSC instead of home_csc
Once booted. try changing your CSC to KOO without a sim inserted still.

Any updates?

well there is no way to do that unforuantely unless rooting

[Q] Firmware change unsuccessful

I bought my S6 in Colombia although I live in Panama. It is the SM-G920I.
I found that a Panama app I wanted to install would not install because it said the country was wrong. I guess that may be something to do with the CSC. I had naively assumed the phones in Colombia would be the same as the phones available in Panama. I now see from Sammobile that there are different firmwares for Colombia and Panama. So I downloaded the Panama firmware and installed it with Odin. Odin did its stuff and said that the installation was successful. Both firmwares are 5.0.2.
However, when the phone rebooted it was exactly the same as before and PhoneInfo still shows it as having the Colombian firmware. The only change was that I lost my Pingpong root.
Sorry for the long explanation but what have I done wrong? How can I get the Panama firmware on the phone?
TIA

You Need to download another firmware, i recommend to you to download the Trinidad And Tobago firmware, i tell you because latin america has csc codes for many countries but if your country does not have csc code it sets to latin american firmware because of your EFS Folder, if it doesnt work to you please download a firmware from France or Spain. if you doesnt want to lose pingpong root do not upgrade to a kernel made after 15 May 2015
Please do not upgrate to 5.1.1 Firmware it Sucks

Thanks. I will give that a try. Would it be the CSC that is stopping the app I want from installing, saying it is the wrong country?
If so, is there an easier why just to change the CSC? I have done some searching but everything I've found seems to be quite old and probably not working for Lollipop.

Try this to change your csc code:
1. type in the dialer *#06#, copy ur IMEI
2. type in the dialer *#272*IMEI HERE and add a #

Thanks but that doesn't work. I get Unknown Application. I think that doesn't work on the S6. I also tried using Phone Info to change the CSC but that also doesn't seem to be compatible with the S6 even though it shows my firmware is multi-CSC.

Sorry but what do you mean do not let to install csc files? I did stop Odin auto-rebooting and went to recovery but that didn't seem to help. How do I stop it installing the wrong CSC files?
If I was willing to lose warranty now, would installing TWRP and maybe a custom ROM make it easier to change the CSC?
Thanks.

I am stuck in BNG csc code and i cant change it because i need to Trip KNOX, but i changed my csc code From ING to BNG.
- When odin finish flashing if Auto-Reboot option is ticked, your samsung will reboot and it shows a Android robot instaling something and later says Erasing... you cant let this happen, untick auto reboot and you need to reboot your galaxy in recovery mode and it will show CSC Check Failed and you have to wipe data and shutdown your device and enter in download mode and reflash the firmware.It worked for me.
if you trip knox and you install twrp it will be easier because you can install a custom rom and change your csc code rooted.

Change Galaxy S7 CSC

Hello, i'm trying to change my DBT(germany) CSC with UK one but even if i flash with odin last uk firmware with repartition, every time phone restarted main language and CSC doesn't change. How can i align product code, CSC and firmware?
Thanks
I had the same problem. After 8 unsuccessful attempts I was able to change CSC. But I had to flash ETL ROM and after that I was able to flash BTU. DBT and VDC/VD2 are nasty multi CSC.

This means you have to root the phone right? Can it be done without rooting?
I did not root me phone. CSC can be changed, but it's challange for VDF/DBT firmwares.
As I said, after 8-9 attempt I achieve to change CSC (also had custom status v DN mode).

Hi XDA community,
I have a stock S7 Edge, which now has the XSG CSC (UAE). I want the XFA CSC (unbranded South Africa).
Problem is XSG and XFA are part of a multi CSC (OJV). Everything I've read says this can't be done unless I root my phone which I'm unwilling to do for now.
I'm sure there's a smart someone out there that has figured out how to do this!

Any way to get VoLTE working with international phone?

Hello
I bought an s8+ from HK which is the dual SIM Snapdragon version (G9550). Using it here in Australia, everything works as expected as it supports all of our bands, however VoLTE does not work. I've read this is because the CSC does not match a local CSC.
Unfortunately there are no Snapdragon versions sold here, hence no firmware with the Aus CSC (XSA) that will support VoLTE (as I read you can't flash the Exynos ROM onto the Snapdragon).
Is there any way I can enable VoLTE? Can I somehow change the CSC without an official ROM? Like go into the G9550 ROM and replace the CSC with the Aus CSC?
The only other region with the Snapdragon is the US from what I can tell, which probably wouldn't enable VoLTE either.
Any advice is appreciated
Thanks.

You may root and then flash your csc zip (or simply replace the CSC files in the custom rom with your CSC files). You should get VoLTE. Download Multi CSC file from here and extract your csc.
I do the same but with India CSC on USA snapdragon models.

Thanks nimms. This is pretty much exactly what I was after, except I cannot root the phone (work required Knox so I can't trip it ). I was hoping I could do somthing like the above, only via Odin, but it sounds like you can't change the CSC without rooting the phone due to making system changes.
Try this code in dialer *#272*imei# and change your csc from there

Hi
As far as I'm concerned, this is not possible without tripping the Knox counter. And if you try flashing the XSA CSC (via Odin), you will definitely soft brick your phone
ims setting. maybe can fix your issue ,just download a hidden app display. then you can open ins setting

Interesting.
Another question...the only difference I've noticed between the 9550 (HK) and 955U (US) is that the US version does not have Band 28 but the HK version does, which we do use here in Aus.
If I flashed a US firmware (which has the same S835 SoC), would I lose Band28, or would the modem still be able to use it?
EDIT: what if I only flashed the CP file (modem), is this interchangeable between the different SoCs? Could I flash the XSA CP (modem) onto another ROM, or will this soft-brick?

My IMS is saying "Not registered" in the about phone. I can't seem to do anything about it, and the hidden menu doesn't give me the option to change it.
IMS setting is located explicitly on "Settings -> Mobile Networks -> Access Point Names"
The best bet you may try is to find a Samsung phone thats currently in VoLTE then copy IMS apn settings onto you phone (you manually input the settings).

MY Galaxy S8+ SM-G9550, SW - G9550ZHU2AQL2
Just download an official ROM (A variant from a country that supports VoLTE) for ur model from sammobile or u might even find it on the xda forum and flash it via odin with Home CSC.
It works well... No need to root n KNOX counter wont be tripped...
PS: Backup data.. They will be lost in the process.
Now we're talking about ADB, not ODIN or TWRP.
Flash via ADB Sideload - not possible. You understand me. Smartphones snapdragon not flash Exynos SW. You can only edit an existing profile CSC or add new CSC.
Example:
my smartphone TGY (snapdragon model SW)
but I live in the region of SER (EXYNOS MODEL SW)

Then CSC change with SamFW works.

It was not a bug that samsung needed to fix. It is intended to enroll indian users only as update targeted for India
If you read discussion here, you can find, simply changing CSC didn't worked to enroll for beta programme.
Myself from India only so i haven't personally needed to change CSC though.

To change CSC - no SIM needed.
To switch to beta program - SIM is needed. Maybe eSIM will be enough to do the trick? $5 https://www.airalo.com/india-esim

PS : Indian doesn't only mean person from india, It is relating to India, or its people, customs, or languages.
This is what i'm trying to do but in UK. I'm currently on EE on my s22 ultra and I have tried a way to enroll to beta program.
If i change csc to BTU it will change automatically to EUX but not a full change because i still have the operator coding EVR. All i get after reflashing csc is EUX/-/EUX/EVR and no ota updates. From what i have reed Samsung has changed BTU with EUX for faster updates at least for S22 Ultra.

KTC and KOO are in N model, so you can try.
The firwares are original.
If your device is network locked to sim cards of your oprator - it may not work, but you can flash back to KTC.

no the phone is not locked to a sim.
right now I'm outside of Korea and I'm using the phone with a non Korean provider and it is working fine.
I'm just trying to change csc to be able to remove the ktc bloatware and settings from the device.
Anyways so i will need to use Odin to flash these files : BL, AP, CP and HOME_CSC (not CSC_) files.

Anyone has SamKey credits? I'm trying to change my CSC from ZTO to INS to get access to the Indian Beta program, but Samfw didn't work for me. I would be very glad if someone could help me

ZTO here too (Brazil of course). Why don't you install INS firmware under ZTO (using the update from 01/08 that is the same here and HOME_CSC to keep your data unmodified)?
After that, install the beta update through ADB or Alliance. I did that and worked like a charm.

no the phone is not locked to a sim.
right now I'm outside of Korea and I'm using the phone with a non Korean provider and it is working fine.
I'm just trying to change csc to be able to remove the ktc bloatware and settings from the device.
Anyways so i will need to use Odin to flash these files : BL, AP, CP and HOME_CSC (not CSC_) files.
then after that the phone will restart then I change csc with samfw?

P.S.
Another friend with A13 (SM-A137F) EUX could not change at beginning.
Flash with EGY and then changed successfully to EGY with call recording.

I just checked Samfirm and for A13, EUX and EGY belong to different multiCSC (OXM and OJM)
So it makes sense that u need to flash EGY firmware first to change from OXM to OJM
In his case, all Korean CSCs, including unlocked KOO, belong to OKR multiCSC, and I heard that Samsung specifically blocked CSC changes with Samfw and Samkey in newer phones (S21/S22 etc) for Korea (N model).

It is not possible to change CSC without tripping Knox. You must unlock the bootloader to change the CSC.

Unlock the bootloader and use Odin to flash OXM firmware. OXM is multi-CSC, so you should be able to change region to India.
Don't forget you can use the Search function to look for solutions to questions that have been asked many, many times before.

If you unlock your bootloader, you can install any CSC you want, so you'd just download INS firmware and flash it using Odin.
Or, you can flash the OXM firmware and simply change the region to India, as I stated in my first reply.
Ok i got that now second major issue is that i cannot unlock my bootloader as my developers option is not showing oem unlocking
no need to unlock your bootloader to change the CSC, just use this application to do so

Can you suggest best US based csc with regular ota updates as i am not getting ota update on gcf....stuck on may security patch update....
Can GCF based devices get ota updates i read it in someone's post that they can be only updated via odin or sideloading
GCF gives more LTE and 5G bands support so maybe that's why your phone has it set on that. You can change it to XAA as it's bloatware free and gets regular updates.

Wanted to ask it just out of curiosity....there is no way to change my csc from USA version to Indain version....by any means?
I don't think this is possible... and that's why Samsung has different variants for different countries ...
Okkk....
But by any chance u get to know that it can be changed to Indian csc please do let me know it will be very helpful
Thinking of flashing this firmware update via odin....device model number : SM-S908UZKEVZW
Region:VZW
OP, Are you sure it is an "unlocked" version? Based on he last three charactors of the model# you provided says it is a Verizon branded phone. Yes, technically it was unlocked after 60 days, but since you are not connected to Verizon's network, that may be the reason you are not getting OTA updates.

As for unlocking the bootloader, none of the US variants' bootloaders are unlockable.
I changed my csc code from GCF to USC and now in sim card manager settings it is showing only sim1 option and esim no sim2 option is available
