Sim Card Changed Error after flashing new rom. - Samsung Galaxy Note 9 Questions & Answers

Hello, recently i've flashed 2 roms on my Note 9 N960F version, everything works fine but when i insert my SIM card in the phone it promotes me with this error " Sim card changed, please restart to start using your new sim card" when i restart, the error pops up again. Iam able to receive calls and everything but cant use the phone since the error doesnt go away. Any help with that ?
The ROM i've flashed is LightRom https://forum.xda-developers.com/galaxy-note-9/development/teamexykings-lightrom-t3890084
Thanks in advance <3
Edit : by 2 ROMS i meant 2 different ones, same error pops up on both

try flashing with the latest odin csc_home.md5 corresponding to your sim cards CSC or region.
csc.md5 can also be flashed but might wipe data.

Do you mind telling me where the csc.md5 ? the phone came from UAE but im living in Egypt, do i flash with the csc being the original place where the phone came from ( UAE ) or to egypt where im living ?
EDIT : I just found my phone's CSC from Sammobile.com if i flashed CSC do i have to flash to stock rom or the custom rom will work with that csc ?

just the csc.md5 or home_csc.md5 should work.
you can also download your firmware with sam firm tool 0.3.6 as well. should be much faster.
regarding csc, your sim card is from a carrier(phone company).
carriers have a 3 letter code that identify them. you can use that 3 letter code to search and install the csc file.

So it is ok to just flash csc on a custom rom, right ? if yes, do i flash the csc via odin ?

as always do a full twrp backup 1st.
flash home_csc.md5 = no data wipe
flash csc.md5 = possible data wioe/phone reset
also id take out the sim 1st, flash and make it boot to home screen. then shut down phone insert sim and then power up again.

N950F/DS - can I use SM-N950F/FD/N roms?

Hi
The N950F/DS as much as I can make out is very similar to SM-N950F/FD/N except for dual sim.
Can you install SM-N950F/FD/N listed roms like say Ironman?
Just pre-planning as will want rom support.
Thanks

As far as I know the N950F/DS is also known as N950FD. This is the same model, just written differently. Now this model is just like the N950F, except it has dual SIM. When I bought the N950FD, I checked the settings menu and it actually says N950F (but again, it has a tray for 2 SIMs, or 1 SIM + 1 SD card). To my knowledge, software for these at least should all be interchangeable. In other words, there is no N950FD or F/DS firmware, just F firmware. The N950N is indeed a different model, so I'll let someone else speak to that one

Ok, two more questions...
Did you use 'csc' or 'home_csc' in Odin?
And have you tried to factory reset since flashing stock again?

I am not 100% sure. I suggest asking in the thread of the rom.
Personally, if you have the DS version I would only flash that rom if it has DS in the title, which I don't think Ironman Rom has. (ALEXNDR Rom for example has)
A guy above it seems had the DS version, flashed a rom, I suspect to be one with does not state DS, which has now made it single sim, which I can't help him with..
Yet again, I could be wrong.
@sefrcoko i use only CSC.
in odin i check nand erase

Ok, so you used CSC along with the BL, CP, and AP files, right? That should have wiped your phone and put everything back to stock, but if still not working maybe try a factory reset at this point (backup first of course ).

I try but not work. some apps says: the displayed model is not correct SM-n950F
well i try repair phone on z3x box

back to stock - no phone signal

i had AMBASADII v4 installed on my n950F/D and all was well.
i sold my phone to a friend who was freaked out by the word root.
so i loaded up ODIN and installed MID_SM-N960F_1_20190211112001_r1d73jpuzn_fac using the CSC (hot home_CSC)
now the sim card manager doesnt work (freezes) and the device doesnt read the network (phone signal)
i am now downloading the latest ROM from https://updato.com/
what did i do wrong? could it be i had to do home_csc and not csc?
or maybe the ambasadii i had a newer CS and BL and the stock had an older modem file?

i know that's why i said note 8 and note 9.
ure probably tring to flash an old firmware on a newer bootlaoder rev. fone.
be sure to flash all files aswell... not just AP or CSC
but all 4 md5's.

ya exactly. i know i am flashing an old firmware ...when i had ambasadii i had updated the BL and CP ....
but still, if you flash a FULL suite of the files it should still work, right? i mean we're wiping fresh and restarting. why is the new one sticking? it should revert to the old one from the old firmware.
anyways -- ive downloaded all the latest and we'll see.

seems CP from ambasadii is still more recent than what ever was dled on updato.
try using samfirm tool 0.3.6 and really get the latest. or try sammobile.com
latest should be august patch.
get BTU region/CSC firmware

no no. you quoted me because i replied about the issues.
i still have not tried the downloaded NEW ROMs...i was just speaking of the ORIGINAL issues. i'll try later and see. the phone is with my friend, the person i sold it to.
on a side note; how do i make sure what the BTU region/CSC is from serial/imei ?

BTU csc is actualy but one of the carrier sales code within the oxm region and should cover what ever sim you put in it. imei is just the phones ID shown to the provider.
I suggested BTU (uk unbranded) as oxm is not a searchable/downloadable firmware persay. i could have just as well said DBT which would also be within oxm and be the same firmware zip file. using those region codes usually yields the most up to date multi csc firmware.

which N960N software version does support the DUOS (2 sim card)

Greeting
I am looking if the N960N NOTE 9 Korean version does support the DUOS, I have a Samsung note 9 which is ( second hand ) definitely support 2 sims, it is written on the back cover DUOS, and the sim card tray is showing sim 1 and sim2 written on it , also the device back shows 2 IEMI but same numbers, when I got the phone I noticed that it is rooted ( which I don't like), so flashed it with oden to original stock firmware, but got problem that the Korean version of the software is not showing nither the sim manager or 2 sims IMEI numbers like before , now I am looking for a software (stock) which may bring the 2nd sim card slot back, any suggestion or numbers or versions ?
the version I used until now:-
1- N960NKSU3CSI2_N960NOKR3CSI2_KOO
2-N960NKSU3CSJ1_N960NOKR3CSJ1_KOO

süre, you go to DR KATAN procedure fır detailed one , but will go quickly with this :-
unlock OEM on developer option ( this is the hardest part as long as it wont just appears when you go developments,
then you go download the patched oden version ,
then you boot download mode and flash the TWRP recovery file , you need to press vol up and baxby and power when pressing start on odin , after that you will be in the recovery mode and able to flash the Dr Katan rom , you will see 2nd sim working in his rom

hello brother i'm having same issue with my note 9 N960N as u mention ealeir can u share the detail and rom with me please
hello there ,
I cannot post link due to reputation, but i will guide you to the right way , in google search for dr ketan rom n960 note 9 , then you there download the rom file and put keep in computer , then go To developers option and unlock OEM , then get The Patched version of oden and follow these steps :-
1- download TERP recovery file from official site for the note 9 latest version
2-open oden and choose the recovery file you downloaded as AP file
3- power off the phone , hardly press power button + volume down and connect the cable from computer to the phone , the phone will boot to download mode.
4-press power + volume up together , and press start , wait until your phone will boot to recovery mode , after that you need to WIPE EVERYTHING OFF FROM YOUR PHONE , i will suggest you keep copy of phone with smart switch.
5- from here you can flash the rom you downloaded before by copy it to phone via cable and flash it as any other rom
NOTE THAT THIS MAY DAMAGE YOUR PHONE AND I AM NOT RESPONSIBLE OF THAT , YOU DO IT ON YOUR OWN RISK....
after phone boots you will be able to use your 2nd sim
Happy flashing

Question Dificulties change CSC !

Hi there!
I'm from Brazil, here we use the ZTO CSC, but this file is ARO/ZTO/ZTA. Every time i flash the files on ODIN i got ARO active on the phone, not the ZTO. I have both sims to be brazilian operators (ZTO) but it still gets ARO active.
Somebody have any solutions for this?
Thank you!
Use SamKey

Are you using the CSC_OYM or whatever it is called in the firmware pack instead of the HOME_CSC at time to flash it through Odin?.
Formatting data via stock recovery prior to go to Odin and then flashing the proper firmware including the proper CSC file to clean all the remanent carrier traces may solve it, I think.
Yes

Yes! I did Just that but without success, I think the code way (*#272...) Will work only with personalized csc, multi csc wont work too

[Guide] How to convert s10-g973N to sm-g973f, change csc from skc to koo or any another, fix emergency calls only. No need of paid apps, boxes etc.

**********This is first time am posting a guide so pardon me. *******
********As usual am not responsible for anything that happens to your phone.*******
*****Am not claiming ownership of the above technique, its what worked for me*****
I saw many posts here about people struggling to change csc from skc to koo or international***
Others had issue with their phone suddenly lost network and just displays emergency calls only****
so I have s10 sm-g973n which had csc as koo then flashed skc my mistake. The phone booted with annoying skc boot logo, and branded junk from the carrier. Then one morning the phone couldn't connect to gsm network!
I tried all manner of things to fix it. Rooted with magisk, flashed custom rom nothing.
Tried samkey to change csc still nothing. modified odin in flashing multi csc rom nothing.
Got some luck in changing csc by editing efs/imei/mps_code.dat using root explorer, text editor and vola the carrier junk disappeared. But still no network.
was told only way is to use z3x box or chimera to patch certificate but didn't give up. I posted question here in xda but no guide or response.
But that gave me an idea of what could be the issue- corrupt efs that needs the certificate to be patched. so got keyword.
After watching many YouTube videos I came across a video about a rom that has certificate patched. Just flash with odin and done!
I downloaded and followed the instructions. The phone booted up fine and after going through initial setup the network was back!
Not only did the network came back but the model changed to F, csc became oxm! You can now use tools like Samfw from too to change csc to your local region.
Later in the day, will be flashing firmware with my region csc.
Here is the link to the rom:

Yes sim 2 will work. And after completing flash stock rom for security reasons. Because the above rom is rooted and modified we don't know how secure it is. after network certificates are patched now flash a stock rom from eg sammobile or samfw etc.

Did you find a fix for that? For me the internal memory become 32Gb. Is there a solution for that?
I bought an S10 that turned out to be a G973N(SKC) flashed to G973F-D/S(XSG). I think they used this method and these files to do it. I can't get the OEM unlock option to come up. I've tried everything. I am starting to think that it's because of the XSG country code. I was going to try to change it XEU (Great Britain) in SamFW but it just stalls and doesn't do anything. Any suggestions on what I can do here to change the country code? I need that OEM unlock option so I can degoogle it.
Hi guys,
I have I big problem with this rom man, each time I restart my phone i lost network and I have to reflash your rom and factory reset the phone to get it back. It's like it's forbidden to restart the phone, otherwise my network get lost and IMEI Status NG again.. Is there a fix for that? Thank you. Is there a for that fix?
Or do you guys have a rom based on android 12 for g973n u7 converted to dual sim that can solve this IMei STATUS NG? I watched on youtube some guys that have it but it's not free or I can't pay that from here in my cluntry the poorest country in the world.
Thank you guys.
