Greetings,

I am a new user here. I just bought Galaxy S10e and I really like the phone, but the problem is that I ordered it from USA (I live in the Republic of Georgia). Originally the phone was from AT&T, but the seller had it unlocked for any GSM carriers and it works fine with my Georgian sim card. The only problem is that I do not receive any software updates. It is stuck on Android 9 and One UI 1.0. When I try to check for updates, it says that my software is up to date. The same happens with Smart Switch.

I tried Frija and Odin. My CSC is G970UOYN1ASD9 and PDA is G970USQS1ASD9. There is no way to download firmware for my own country's CSC, because there is no firmware for SM-G970U (Snapdragon chipset), in Georgia they only sell Exynos ones officially. So, I tried to find updates with CSC ATT in Frija and it does not give me anything. I tried XAA and XAS (which is for unlocked phones) and still nothing. I tried TMK (I think it is for MetroPCS) and USC (This one is for US Cellular) and also TMB (T-Mobile) and they do have Android 11 firmware. But now I am afraid I will break something if I install above mentioned firmware to my device. Or maybe I will not break anything by changing the CSC, but maybe there is also a chance that if I install the above mentioned ones, the phone will get locked on these carriers and I won't be able to use my sim card. Is logical, or am I just overthinking it?

Any help would be really appreciated.

Thanks in advance.
 
don't flash your nations CSC- that shouldn't matter. Snapdragons LTE bands should be good enough to work internationally

go and reflash a USC or XAA rom with patched ODIN... I had to do this for my phone and OTA started working once it was on the correct CSC


you could even flash it to the latest firmware if you wanted too.

Thank you for your answer.

What do you mean by correct CSC? I believe, my phone is on correct CSC now. I have already pasted it and in about phone > Software information > Service Provider it says ATT/ATT/ATT. But it seems that ATT doesn't receive updates outside US.

I cannot seem to find firmware for XAA/XAS, there is one for USC but I have already downloaded TMK. Is there any difference if I install USC or TMK? (TMK is MetroPCS).

Hi GSamkh... Did you upgraded to 11? Im trying to do the oposite, downgrade from Android 11 to 9. If you didnt the upgrade, can you check if the secure startup (or secure boot) its avaliable? Since in Android 10 and 11 isnt...
Seams that secure startup works on Galaxy S9 with Android 10 upgraded from 9.

Greetings,

I have already updated to Android 11 using U1 XAA firmware and it works great. I used Frija and then Odin if anyone wants do to do this. Weird thing happened though - when I flashed the firmware and when Odin did it's job, the laptop suddenly shut down and I couldn't turn it back on. I had to disassemble it and unplug the integrated battery, plug it back on and fortunately it turned on again.

As far as your question goes, I am sorry but I cannot check it since I am already on Android 11.

Hi GSamkh,

I am experiencing the same issue as you, purchased an AT&T branded SM-G970U for use in Australia. After you flashed to Android 11 using U1 XAA firmware, do you now receive OTA updates? cheers
