How do i revert my Samsung S8+ firmware to the correct version? - Samsung Galaxy S8+ Questions & Answers

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

No OTA Updates

I just took delivery on a SM_P905V, what a beautiful piece of equipment.
It was used in is loaded with Android 4.2.2. When I go to update software, it says its unavailable.
How do I get an OTA update?
Edit: Samsung site had the OT1 Lollypop 5.0.1. Now I wonder if they will update to Marshmellow?
Running great; and I couldn''t be much happier.
I suggest you use 'odin method' because its really fast but if you are not experienced with that method then I suggest you use samsung kies3 software on windows to update it. As for ota method, It varies region to region if new software isn't released in your region then use these alternative methods. Thank you , hope it helps
Hm, latest version for the P905V is P905VVRUBOH1/P905VVZWBOH1
Was it a new device or used?
You can use ODIN to flash the latest firmware manually. You can grab the newest firmware version to flash off Sammobile.

How can I get nougat on my NXT-L09C636B191? Firmware finder app doesn't work.

Just trying to somehow get nougat without rooting or anything. Firmware finder shows an OTA available for L09C636B593 but I can't get it to go into updater.
This is a good question because I'm in the same boat
same to you

About the only way I've seen so far, is to load twrp, screw around with other files, load a custom rom.
Until the rom shows up via the stock updater, or, the firmware finder app shows something that says
FULL and not OTA or FullOTA, you and the rest of us are stuck until Huawei officially releases it.
It's not that bad of a deal though, 6 for me anyway is VERY stable.
I agree it's stable but one of the reasons I bought a huawei phone was they are supposed to be the first to update to new versions and here I am still waiting. I thought Samsung was bad but guess what the s7 is already on android 7 and I'm not.
I think I'll be going back to Samsung soon as the note 8 comes out.

from L09C636b210 you can update via Firmware Finder to L09C636b521. Then go to System Update and you will see L09C636b563 update available. I recommend DOWNLOAD LATEST FULL PACKAGE from the pull down menu.
The update came for me, but not through firmware finder. Mine came through the built in update program
in the phone.
Mine was L29C185B180, then I got 321 through firmware finder, but it never would update. When I saw someone
post that 560 came through, I tried firmware finder, never had anything, but when I checked the Huawei update
app and it showed up.
I uninstalled the firmware finder app. Nice idea, but didn't work for me.

Manually updating to Oreo

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?

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.

Thanks for responding!
I managed to flash an older firmware from 4 months ago and I was able to OTA update to the recent one. https://forum.xda-developers.com/at...lternative-t3844887/post77673505#post77673505

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.
