Hello, I live in Korea.
The phone you use is Galaxy samsung galaxyS10 5G(SM-G977N)

But there's a problem.
I'd like to change the CSC.

The CSC currently in use is LUC.
I would like to change the CSC to KOO in Korea.

However, the firmware of the KOO model was put in AP,BL,CP,CSC,USERDATA and it does not change.

Is there any way?

Please give me a good answer.

Flash to Odin, but it won't change.

Install firmware with samfirm with countrycode u want then flash

-------------‐--------------------

To change from CSC LUC to CSC KOO, the company received the initial firmware with countrycode KOO in the Sampirm and flashed it to Oddin, but it does not change. Is there any way I can change from CSC LUC to CSC KOO without turning?

Saudi doesn't have 5G yet, of course it won't connect to something that do not exist.

No Sir , we have 5G launched by 2 service providers (STC and Zain) so far and the third coming soon :)

I'm trying to figure out the issue preventing 5G connection, whether it is incompatible band frequency! or phone firmware (Koria oriented) is causing the problem!

firmware versions are :
