I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQC9 Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates. Every time i try to update it says that its up to date.
My phone is not rooted or anything just a normal phone. I am just trying to update it to the latest Android Version 9.0(Pie) , I just made this thread for the reason of maybe someone can help me on updating my phone.
I also have tried updating through SD card and Smart Switch but none of it works, On Smart Switch it says that my device is up to date :QC9(ATT).
