Rooted Galaxy S8+ - Easy to move to Oreo? - Samsung Galaxy S8+ Questions & Answers

Hello,
I'm a total n00b when it comes to this stuff, but when I bought the new Galaxy S8+ I managed to root it using guides on this forum and it's now running an old version of the software.
Some data:
Phone: SM-G955F
Android version: 7.0
Build number: NRD90M.G955FXXU1AQDD
I know this is kind of old (1 April 2017) but it took me so long to set up root, get Magisk masking the right apps and customize the phone as I want it, that I didn't dare update the software with anything newer in case things go wrong.
Now that Samsung will soon be releasing Alpha Oreo versions, I was thinking of maybe moving the android version forward to something newer.
My question is, how easy is it? Is it just a matter of flashing the new release via Odin?
And will I lose any of my configurations? Will I lose root? Is root even possible in Oreo??
If it's not too hard of a process I might try it, just looking for some enlightenment.
Thanks!

Once the official version releases check for the ROM you're using to update as well, or flash one that's been updated. Unless you take the OTA on stock it's going to require you to full wipe though. Even then I would full wipe, you're upgrading to an entirely new version of Android. Dirty flashing not recommended at all.

Can a root device be upgraded?

Hi all
A week ago a rooted my Samsung Galaxy S6 device following this post: http://forum.xda-developers.com/galaxy-s6/general/root-pingpongroot-s6-root-tool-t3103016
All was OK. At that point my device is using the Android Version: 5.0.2
The question I have is that now the version 5.1.1 (Lillipop) has been released, I would like to know if my rooted device can still be upgrading when the new version is released in my region (Mexico) by the phone provider. (Telcel). In case it cannot be updated automatically, I guess I will need to do it manually or unroot my device. In that scenario, Does someone know a good tutorial how to do that?
Regards!
@LesthadMK, sure you can update rooted devices. But it may not be possible via OTA update. You will have to download the full firmware and install it manually.
Because root makes changes to system partition, OTA fails when you have rooted. If you unroot and flash stock recovery and kernel back, then OTA may work. Otherwise, simply flash the full firmware, in .tar format using Odin software, and you're good.
It's good to have full firmware saved on PC anyway, as if in case you brick your device, you can fix it by installing your device's firmware manually.
If you need help with 5.1.1 firmware installation on your s6, let me know the build no. of your device.. I will guide you to page you need to look at.
Thanks for the help. I have download Odin in case I need to do it manually.
Also, mentioned that yesterday I read an article saying that using the Samsung software "Smart Switch" in an rooted device will upgrade the device to the newest version (which I don't know if it it's true or not) Any way this is the link I found:.... Well seems since I'm newby I cannot post some external links. So just google it as: How to Use Smart Switch to Update Your Galaxy S6—Even It's Rooted.
By other hand, this is the build number for my device: G920IDVU1AOE3, so if you can help me to know how to upgrade that version that would be very helpful
Regards!

What is the process for Android Updates?

Hey guys. I was wondering, what is the process for android firmware updates? By this I mean, when I owned an iPhone (any model) after I updated the firmware there seemed to be remnants of the old firmware version and it would cause issues through the phone, at which point I would have to go on my computer, restore to the newest firmware essentially formatting the phone and re-uploading the new firmware on the phone. After that all was fine. Is this necessary on android in order to get a new, clean version of the firmware on the phone or does the update process do this throughout the installation? I haven't had any issues yet with the newest AT&T Nougat update, but I was just thinking about this and figured I'd ask before anything did happen, if it's like my old iPhones...
BTW, I'm on AT&T Samsung Galaxy S7 with Nougat 7.0

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?
My phone right now:

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.

Question [TB-J606L] Downgrade from Android 11

Hello. Yesterday i installed latest OTA Android version (TB-J606L_S320030_210923_ROW) and noticed that it is really slow and it has even more bloatware that i don't want. I don't need to root it (because of bloatware removal) as i also need to revert it to default state as it was before update.
1. It is possible to find which version i had before this upgrade?
2. How could i downgrade system to previous version (i think it was Android 10 but i'm not sure)
PS: I successfully downgraded/rooted some devices but as every brand has it's specific way to perform downgrade, i'm asking here. Any advice would help and i'm aware of dangers of downgrading/rooting devices (bricking). In any case, it would be awesome to also link unbricking guide for TB-J606L, just in case It's always better to have plan B.
Update: I found source of roms for my device but i can't recognize which versions are old Android 10 and which are the new Android 11.
