Hey, maybe some can answer this for me?
I have the S21 SM-G991U (snapdragon), purchased from USA, using it in Europe.

There is no OTA update for android 12 and I am not sure why.

So, I wanted to flash it via ODIN, but I am not sure what version of firmware to download.

When I use *#1234# > it shows me this CSC: G991UOYN4AUIN
When I use the "Samsung Phone INFO" app, the "Active CSC code" is GCF (screenshot attached).

Could someone answer this for me and tell me what firmware version I could download? Or why there is no OTA yet?

Thank you!
I have the same problem, mine is G991USQS4AUIN but when i use *#1234# i get CSC: G991UOYN4AUIN
and i dont get any updates
 
1 goto :
setting/about phone/software information/Service provider SW ver
2: download your firmware from :
3: install firmware with ODIN

It's says that for this PDA the android version is R11 ! , so this mean no android 12 for this model ?

You can find that there is already Android 12 released for this model

You can pretty much download any version you want, as long as the model variant matches then you should have no problem.
