I have a Samsung Galaxy S9+ phone, model SM-G965U, that is AT&T branded, but carrier unlocked and being used on the Mint mobile service carrier. I purchased the phone on Amazon.com. The phone has been on Oreo 8 OS, Baseband version G965USQS3ARG8, with Android security patch level dated August 1, 2018 and has never updated and it is now August 14, 2019. When I go to update on the phone, it says..."Current software is up to date" which I know it isn't. I googled this issue and found many others complaining of no updates on the AT&T and Samsung forums as well as elsewhere on the Internet. I called AT&T who said updates were a Samsung issue. I called Samsung who said updates were an AT&T issue. Went to an AT&T store and they said updates were a Samsung issue. Really??? I tried most all suggestions that I read on the Internet for the issue, e.g. soft reset, wipe partition cache, use smart switch on PC, etc. I didn't try factory reset as this is kind of time consuming and others said it did not work for them. The only other option I read about was flashing the phone which Samsung does not want you to do. And if that were a last resort, where would I find the proper ROM to flash the phone (latest, untouched for my model) as Samsung does not seem to provide it. I'd also want to be sure the phone retained its unlocked status so I could continue with Mint mobile as a service carrier. Samsung did also suggest taking the phone to UbreakIfix (their authorized repair shop), but that is a 5 hour minimum ordeal for me that I'd like to avoid if possible and I don't even know if they could help. Does anyone know if UbreakIfix can definately help fix this issue and / or have any other suggestions that you know might work for my issue of my S9+ not updating?
