Manually updating to Oreo - AT&T Samsung Galaxy S8+ Questions & Answers

Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
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.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?
Thanks in advance

You can, however there are specific sequences to follow, so you have to update in firmware released order.
I encountered the same problem so I downloaded odin that worked for Nougat and loaded all version to BRB1 I think it is and then went to Oreo. Currently on CRC5.
Another note, when you are about to hit Oreo you will need to download the odin that works for Oreo. It can be found in the CRC5 thread.
Happy Updating

Is this really necessary?
I want to update to Oreo as well but since I'm AT&T unlocked and not currently using AT&T network I'm stuck in the June software update so I'll have to flash like 7-8 firmware updates and each one being about 2-3 GB to download.
Also, is there any stock Samsung firmware I can download so I can avoid having to manually flash every software update? Or am I just stuck with the AT&T firmware?
Thanks in advance.

I'm also having this problem. Need to flash the updates through ODIN but I can't find every single stock file leading up to BR9 on this site. Do I really have flash them all? Or is there another way?

How to downgrade?

I did the biggest mistake of updating my awesome S7 to the April update patch & now the Android System bug has hit my phone & nothing seems to work for me. Even formatting the phone is not working for me. Please can someone guide me on how to revert back to the March Firmware or is that even possible with samsung phones? This is my first samsung phone.
Have you tried flashing the current firmware using Odin? You should do a factory reset and then flash via Odin and snag your firmware from here. Make sure you get YOUR firmware, since there are quite a few different S7's running out in the wild!

Here is also a nice guide how to flash manually

Is it possible to go back to the March update firmware? The link you have given is for Germany, I am from India which is not in the list any help on that? Thanks for the reply.

Trouble Flashing Samsung S7 to Android 7.0

Hey so.. Phone's root bugged out yesterday and I downloaded twrp and decided I should upgrade it to Android 8.0 then root it. After many hours of failures I managed to flash a 8.0 but I couldn't make the CSC to work, since my phone is region locked to another country so I decided to go back to 7.0 and try again.. but now here it gets complicated because I really don't know what to do. I'm not sure how exactly to go back from 8.0 to 7.0.. Can someone give me detailed steps on what should I do.. I'd be very grateful!
PS. I don't know if I'm posting this in the right forum thread.
Here https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
Same site, or sammobile can be used to get the firmware files to flash with Odin
Note: The last version of 7.0 locked the ability to downgrade, I haven't gone to Oreo so can't confirm, but it ability to downgrade may also be removed from Oreo.

I can confirm, downgrading from Oreo 8.0 to Nougat 7.0 is possible, even without tripping knox.
It's just flashing the previous firmware with odin and factory reset the phone before first run and you're fine to go

US Galaxy S8+ OTA software update not working / alternative way. SOLVED

What I want to do: I was trying to OTA update my phone software to the latest, but it seems I am behind on many updates. On the AT&T website, I saw that I need the previous updates installed first, in order to get the latest ones. I have to go in order.
Problem: Everytime I try to do a software update from the settings, it says “Current software is up to date.” It’s been saying that for over a year now. I can’t even get the updates from last year.
So is there a way I can flash one of the stock firmware updates from last year on to my phone with Odin and see if it will fix the ‘over the air’ updates? Or can I just skip to the most recent firmware and flash that one.
By the way, I have never done anything like this to my phone before, so I am a bit nervous, but I want to get this problem fixed so I would love if someone helped me out. I did see some articles online about flashing stock firmwares, that’s how I learned about Odin.
If this is doable, can someone please link me to a thorough tutorial on this process? If it isn’t, can you guys recommend another way of getting to the latest 8.0 stock firmware?

If you are using the AT&T S8+ outside of the USA, you will not get any OTA updates due to AT&T update policy. What you want to do is flash the Unlocked firmware and you will be good. Search for carrier switching thread and follow it.

You can Odin flash CRG3 and the next OTA should be CRHI, so once you go thru settings, check for updates it should want to go to CRHI. And then you should be in the Update path to receive OTA's automatically

Thanks, so is it okay to flash it with the latest version of Odin? Also, do you mind linking me with an up to date / reliable tutorial on this? This is my first time attempting to do something like this.
One more thing, on Sammobile, there is only one firmware available for at&t, and it's the oldest one.

Okay, and is it okay if I flash from a firmware from May 2018? It's about 4 months old. Would I be able to OTA update from there on? Also, what is AT&T userdata? I came across it in this thread and I was wondering. https://forum.xda-developers.com/att-galaxy-s8+/how-to/g955u-att-stock-odin-files-firmware-t3769140

Yes you can use this firmware and start to receive updates, User data I'm not 100% sure but I think its supposed to flash your data so you wont have to reinstall everything but I heard it dosent work for At&t it will still do a complete wipe before install.

How do i revert my Samsung S8+ firmware to the correct version?

A while back i had tried installing the android pie update for my samsung s8+ in canada and of course it did not work. As always samsung takes 100000 years to put out an update and its still not here. Anyways i havent received any updates since and my software version is probably not right. I was wondering if it will automatically update when android pie comes out or if it wont update at all. Also the device security isnt working so thats a bad thing thats why i want to try and revert it. Thanks, sorry for the unclarity if any.

And the software for which version did you flash exactly? I assume you have a G955W variant? If so then it should be as easy as downloading the latest firmware from fw.updato.com or search Google for Samfirm and use it to download the latest firmware for your phone. Flash via Odin and it should be back to normal.

The baseband version I have is G955USQS5CRL1, which is weird cause I downloaded the G955W software... Build number is R16NW.G955USQS5CRL1
