Emergency calls only. HELP!

[Android Central Question]

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

You sure you seen the correct model number because (SM-G960F/DS) is dual sim and the one you need

Hi, welcome AC !

So just to reconfirm , which model did the phone come with ?

 

[Thepredictor123]

It had G960F installed. Which was of course a custom rom. Flashing stock android 10 fro N model gave me "imited service" or "emergency calls only" error for the sim.

 

[mustang7757]

Where did you download the stock firmware from ?

 

[mustang7757]

Also while you were on the custom firmware everything was working?

Looks like you converted the 960f to 960n Korean version , maybe look at this to help get the Korean bloat off and language thats if you can with your bootloader Andriod 10

Downloaded the stock firmware from sammobile. And yes everything was perfect on custom rom.
No. I didn't convert it to N model. It was an N model comverted to F by a custom rom.

Try flashing the firmware from frija tool which you can download the latest from XDA and see what happens
