No software updates coming in my s23 ultra

[esh_k]

I bought S23 ultra from Singapore and got July patch there. After coming to India, changed my csc to ins but till now I didn't get August security patch and also I registered in one UI 6 beta but I am not able to get any update in my phone.

Any ideas how to get regular updates?

What's the model number of your device?? How did you change your CSC?? DM me if you need a solution

SM-S918B
I changed csc using *272*imei# (not working now to change back again)

This method doesn't work to change your CSC on S23 Ultra...

It actually worked for me seriously.
But now this is not working

I did the same thing to change my CSC using *272*imei# . 

May i ask , if there are any other options to rollback to it's orginal state without flashing.

You can use a tool called SamFW to change your CSC and return to your original CSC without flashing your device

This is the current version of my software after changing the CSC. Despite multiple attempts to revert back, I have been unsuccessful. Based on your suggestions, I will attempt to use samFW to revert back to the Singapore CSC.

I also have an eSIM currently active on my phone, and I am wondering if it will be erased if I format my device. Additionally, I would like to know if it is possible to switch to the India CSC completly and continue receiving regular updates as if it were an Indian phone.

Below is my current software version after i changed to IN

Resetting your device won't erase your esim..... if you change your CSC to INS you wont be able to receive OTA updates..... you need to flash the indian firmware on your device in order to avail all indian features as well as receiveOTA updates

Could you please provide me with a reference link to the latest firmware version? Additionally, I would greatly appreciate any links or resources that can guide me through the flashing process. Since I am new to this technique, step-by-step instructions would be extremely helpful. I would like to know if I need a laptop or PC for this process, or if it can be done on a mobile device. Any guidance on where to download the original software and how to execute the necessary actions would be highly appreciated. Thank you in advance for your assistance.
