S23 not getting update

[xd123]

Hi , I recently bought s23 base model US version although it is US unlocked device but I live in Pakistan and not getting update last update was in August 2024, after doing a little research there is only one option to change csc. I want to know which is safest method to change csc ,odin or samfw? As I live in Pakistan my phone csc is XAA which csc should I select.

Any help would be appreciated.

Is it cpid. That mostly happens with cpid phones. You can use any of them but should have same built number

Yes it's cpid ,through samfw I only need to just enter csc which region should I select to get updates and don't affect performance, battery ,features etc.
