Samsung Galaxy S23 - EUX CSC - No firmware updates since May 2023

Hi all

I changed my CSC over to EUX and downloaded the latest firmware from sammobile in May. They oddly have the outdated May update as their last update available on their website. Since then there have been 3 updates released by Samsung (https://doc.samsungmobile.com/SM-S911B/EUX/doc.html) and every time I manually check for updates on my phone it says my software is up to date. I've tried safe mode and using the samsung windows desktop application - both which say my software is up to date.

Anyone come across this issue/behaviour before? How do I go about getting the latest August update to roll through to my phone? Stuck on May and bit concerned with not receiving the latest security these patches they provide in the update.

My CSC has already been changed to EUX despite the EVR showing. That isn't the actual CSC that's being used - that shows who the first network was that issued the phone.

I hear you, I'll give you an example, my s23 ultra has 3x EUX & my first sim i used was & is EE but it still shows as EUX/-/EUX/EUX without the EVR, that's why i suggested to change it back to the original then to the EUX without a sim, that way it won't recognise a specific network but would show the firmware without EVR attached.
Maybe I'm reaching.

That last bit will never change to an EUX, it's unchangeable. It will be whatever it is based on who provided the phone. In my case it was EE so it will always stick to EVR. But that doesn't matter as I can still change the active CSC to EUX and the actual CSC will change despite having the EVR bit. The EVR at the end doesn't count for anything/do anything.

OK, thanks for the clarification.

Are you able to confirm the build number on your phone, please?

Here you go.

That was quick! 

Thank you

[Pugs1957]

Seems like your phone hasn't updated, either. Hmmm

[Pugs1957]

Yes, EUX is not supported with that build number. See SM-S911B Firmware List | SamFrew

and look for the EUX country code.

I looked at one of the tools that tried to obtain the latest EUX firmware from the samsung FUS but it keeps returning back a 401. I'm guessing the same is happening on my phone when I check manually for updates. But I've got S911BXXS1AWD1 and that's listed on this page: https://doc.samsungmobile.com/SM-S911B/EUX/doc.html
(for May). Don't know why I can't upgrade to the latest August firmware?
