Galaxy s9 firmware issue

Hi i have a branded galaxy s9 on vodafone uk which i installed btu firmware on then relised i couldnt use wifi or 4g calling so reinstalled vod firmware now my question is how do i get back the firmware csc as this is missing in phone info app and i dont have 4g calling my product code and active csc are both as they should be many thanks

I have s9 bought from carphonewarehouse, XEU csc and it has WiFi calling in the settings after I rang Vodafone, they just updated my apn settings, im on the Vodafone network too. Only thing is 4g calling won't work without Vodafone branded phone.

My phone was brought from vodafone so is a branded phone until i played with it lol

Lol, was thinking of flashing the Vodafone firmware just to try out volte but judging by what you've just said sounds like it's not as easy as that [emoji848]

I've also had an unlocked phone from Samsung direct but on Vodafone. To get wifi calling just give them a call. No settings are sent to accept it's all done OTA. To get Volte or 4g calling whichever it is you do have to have the VOD csc. But I think it has to be the same version as your original firmware. I've just stuck the ARD4 official Vodafone firmware from Sammobile via Odin and it all works out the box. However when I was on the BTU firmware ARD4 all I did was put the ARD equivalent csc from Vodafone firmware via Odin. Used the home_csc file so no data deleted. However Everytime I restarted I got an annoying message saying some network features not available until I factory reset the phone. But Volte etc working so I was happy. Just waiting for Vodafone UK to update their firmware to BRE5 now.
Hope that helps.
P.s when installing the csc from Sammobile even though I selected the UK one the initial screen came up in German. But after restarting and clearing cache it came back to English.

n920a change csc

hi, when i bought my n920a it had firmware 6.0.1 but with cs XSG of the arab emirates but now i can not flash this csc anymore. How should I do? also when I downloaded samsung flow did not make me use fingerprints because it said that I had done the root previously but I had already bought it so. Is there a way to root?

Are you sure your device was originally an N920A? And have you ever flashed the stock AT&T Firmware to your device yourself manually?
I ask it like that because, if you went and bought a Rooted N920A from an older firmware and then flashed a newer stock firmware to the device, you definitely removed the carrier unlocked modem and reinstalled the AT&T CSC. The firmware does try to prevent all other firmwares from being used.
You may end up needing to flash the modem from the combination firmware in order to regain your carrier unlock status, that may allow you to flash another region's CSC. But you would want to use a Home CSC version if you can. One that doesn't include the PIT file with it. The Home CSC version typically does not contain a PIT file but has a meta data folder that accompanies the cache image. The Home CSC also doesn't require a device wipe.
But if you accidentally locked your unlocked phone, I hope you didn't flash an unrootable bootloader over a rooted bootloader. But using the Combination Firmware's Modem/CP should allow you to change carriers and manually adjust APN or Cellular Settings. Although it may mess up your wifi defaults until you mess with wpasupplicant.

Thanks, I installed the latest firmware available NRD90M. N920AUCS6ERH1. Is it no longer possible to downgrade?

Different region firmware please read

I bought a A50 from ebay it was a SM-A505F/DS unlocked etc its a 4GB 128GB model
now i downloaded the xeu firmware for the UK and flashed via oden and everything flashed and it worked but when I try to check for updates it says processing failed when checking for updates
IT DOES NOT EVEN REGISTER TO THE UPDATE SERVER.
I TRIED WITH THE VODAFONE UK FIRMWARE O2 FIRMWARE BTU FIRMWARE AND XEU FIRMWARE ALL HAVE THE SAME ISSUE
this phone is an XSG model the firmware i used was from the SM-A505FN phone
why does everything work but updates anyone know how to resolve this.

Well if it does not work then you should keep your eye on the samsung's official galaxy a50 development page, and if update is available download the firmware and flash it with odin... Dont worry none of your data will be gone.. and btw if your bootloader is unlocked you wont get updates..

How do you expect it to work by flashing the wrong firmware? You’re flashing a NFC model firmware on a Non-NFC model. Download the desired region firmware for A505F, Remove your sim and flash the firm via Odin.

Best way to get Android 10 without waiting?

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?

SM-G960N Unbranded firmware.

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.

You need to root it and change CSC with phone info app to KOO

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?
