How to change CSC on S23 Ultra

[agrox29]

I bought S23 Ultra in Korea and now I am back in India, How do I change the CSC to INS? I am facing issue with 5G bands as several 5G bands in India cannot be accessed on Korean variant.

You cannot change this.

You won't be able to fix 5g issue on phones bought from outside India.

I know there is no such setting, I mean is it possible to do so using Odin or SamFW on Korean variant S23 Ultra.

the korea variant model no is different than rest of asia, south america etc model no, so you cant flash any frimware apart from korea ones

[john163]

but you can check if the model no has a N in it if not then u can flash, sometimes some countrys sell global version so u could get lucky if you have one, just like i got a south america variant from usa
