Hello
I bought a used s9 a few months back. It had dual sim. In "about phone" it said G960F and was on android 9. A few days ago, I wanted to flash android 10 so I downloaded firmware for G960F, booted my phone in download mode and SURPRISE. The whole thing was in Korean and of course it was a G960N model. So I downloaded firmware for G960N this time and flashed it. Everything went perfect but when the phone booted up, It had no sim service.
I've tried everything I've found on the forums so far related to emergency calls only or no sim service.
Any kind of help would be appreciated. I have no sim service for 5 days now.
Things I've tried so far:
Flashing my phone again with android 9 stock firmware, which I can't do anymore as I've updated the bootloader lol.
Flashing custom roms
Changing csc from SKC to KOO
Flashing OXM CSC as I live in Pakistan
Flashing different modems and basebands
Nothing worked
Anyone??

Alright. I'll try to be as straightforward as possible.
I used to be on Marshmallow, unmodified, stock XEF (Orange) firmware.
Back in September I switched to a PHE (spain) 7.0 firmware because I needed Nougat and it wasn't available for me.
It worked perfectly, no region problem or anything as I had selected Re-Partition in Odin.
Here comes the problem.
Yesterday I decided I wanted to get Lineage OS. What I didn't see is that it was running under 8.1...
I got tired of this version of Android very quickly so I decided to go back to my spanish, 7.0 firmware.
EXCEPT I was getting the sw. rev. check device 2 binary 1 error, which I found out by Googling is some sort of lock that prevents you from downgrading...
So I tried flashing all (AP, CP, CSC) EXCEPT the BL. Surprisingly, it worked.
Except...
Now my phone doesn't recognise my SIM card anymore. I've rebooted it, taken the SIM out, wiped cache, FACTORY RESET... Everything.
What can I do?! Would downloading a FRENCH (XEF) firmware make it work? Please! I need a working data plan...
You have to flash BL else radio wont work .

So, I'm in a bit of a pickle. I bought a T-Mobile S9 while I was in the US, and it was unlocked, so I proceeded and flashed the G960U1 XAA firmware on it. All was well and good, until a few days ago I just got a message that temporary unlock has expired and I need to restart the device. BAM! Phone is SIM locked again. Now, I'd like to unlock the phone permanently, but to do that I need a T-Mobile 'Device Unlock' app. So I went and downloaded a TMB firmware from http://www.imei.info/download-firmware/samsung/samsung-galaxy-s9/SM-G960U/TMB/?pda=G960USQU2ARF7 (it was a 4097MB download and SamFirm is giving me the same file size).
I flashed everything - BL, AP, CP, CSC (not HOME_CSC), USERDATA. Everything went fine, however, after the phone restarted, there was no T-Mobile splash screen, and no T-Mobile apps preloaded. Looking at Software Information, under Service Provider SW ver. I see 'XAA/XAA/TMB'. I also have a T-Mobile US SIM card in the phone (although I am currently in Europe if it makes a difference).
What gives? Is it a bootlader v2 issue? If so, what are my options? I tried installing an old version of T-Mobile Device Unlock app, but it said my device was not compatible with it.
Edit: I did the process once again following the steps in this post - https://forum.xda-developers.com/showpost.php?p=75899735&postcount=24 - and removing the Google account so there is no FRP lock. Result is still the same :/
Hi first post, please be gentle
I've got an s9 which is on EE UK, I flashed the phone with stock firmware, I did run into a couple of issues where when flashing the phone it got stuck on odm.img so I had to start again but using CSC and not home CSC so I lost everything
When the phone rebooted, it started up in German, so as I had my sim card in, it restarted in English
I'm using the following
G960FXXU2CSA2/G960FOXM2CSA2/G960FXXS2BRK3
Service provider SW SAOMC_SM-G960F_OXM_DBT_PP_0009
DBT/XEU/EVR
When I check for updates I get the following
Your current software version isn't supported. Visit a service centre
Can anyone help on how to put this right, I want to stay on stock firmware, not EE firmware
Thanks in advance
Good morning, I have a problem with my S9 model G9600 which came from the factory with the firmware of Hong Kong, however I tried to change the firmware for the one in Colombia because some voice services of the operators only work with the software of the country. But when trying to flash the part of CSC I mark the error and obviously the installation fails as in a kind of A brick because the logo of Galaxy S9 does not pass and is only solved by reinstalling the firmware with which it came from the factory; I have already made sure that the binary is the same, however I can not find a solution. I attach photos of the error.

are you having an identical issue? i ask that because resolutions are very specific. Flashing firmware from www.sammobile.com/firmwares is very commonly the fix for a great many issues, but id hate to have you go thru the trouble of doing so if its not necessary
I tried flashing using odin but didnt work. btw, im using SM-965U and currently residing in Thailand. I dont know if this is the reason why I cant update at all.
S9 message
I am in the U.S. and am getting the message that software isn't supported also. Is there any resolution to this problem?
In case it helps, I was having this same issue with my unlocked Galaxy Note 10+. I found this thread after searching. I had gotten into this situation by flashing CP/AP/BL from TMO firmware without also flashing TMO's CSC or USERDATA. I avoided CSC/USERDATA (I was using the home CSC) because I wanted to avoid wiping the phone.
When I finally gave up and flashed CSC and USERDATA, everything was back to normal.

what is the issue after you flash in Odin?
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?

I Have an Unlocked S20 Ultra 5G from samsung. a while back flashed the t-Mo firmware to have 5G SA access. flahsed the lastest update BTIE. I also have a line with AT&T and decided to try that in my phone and test out their 5G. so i put my sim in and changed my CSC to ATT using the dialer *#272*IMEI# and all was well. went to switch back and didnt think and i selected XAA. now my phone is stuck on XAA, and the csc dialer code no longer works and neither does the *#BAND# dialer code. I have even tried to do a clean flash in odin with the csc file not home-csc and neither one works and im still stuck in the XAA/XAA/XAA.
anyone have any idea how i can get it back to how it was?
