Finally Solved : CSC and OTA Update

[NeelGangrade]

Background:

I got this S24 Ultra from Thailand with CSC as THX, which i changed in India to INS via samfw tool. It took me 5 mins to do that. 

I was really struggling through a point where i was not able to receive any ota update after changing CSC to INS. 

Reason : samsung wallet, samsung pay, call recording etc 

After searching a lot on internet and watching n number of videos, i came to conclusion that the only way to keep you phone updated is via samfw or pushing update manually via Odin

Which is quite a hussle. 

Yesterday i was exploring this phone and came across one setting under developer options. 

It was called as "force update phone upon restart", i pushed it to "on" 

I restarted my phone and to my surprise, holy cow there was an OTA update. 

I dont know why everyone on internet is going crazy and using various tools after changing CSC. 

Hope this helps everyone looking to change their CSC to India (INS) 

OKAY BYE

Does it really work? Or it's just showing

[NeelGangrade]

It does work, and i personally tried and tested on two phones. One from thx and another from dubai

I bought a S20 5G with DCM CSC which is Japanese docomo variant. It has so many bloats. So I changed CSC to KOO Korean Global.

I just flashed the AP, CP & CSC. BL slot is showing error: secure chec fail abl , etc.

Then I restart the phone, now everything working fine but OTA not working.
