No going back to Nougat - Sprint Samsung Galaxy S8 Questions & Answers

Just an FYI.....
T-Mobile is pushing out in the month of May G950USQU3CRD4.... and Sprint will follow suit soon after...
My Sprint is currently on G950USQU2CRC5 Oreo which allows me to go back to the last Nougat of G950USQS2BRB1 if I want, but this new update has a newer bootloader so once it updates there is no going back.... not even to CRC5 just so ya know...

Stepped OTA's from H81010g to MM

I blocked OTA updates after I was automatically updated to H81010g. I was holding out to see if some bootloader unlock method came and have decided to quit waiting. I'm hesitant to go to MM since there tends to be bugs on the first pass. If I unblock OTA's will it step through the updates in between 10g and MM? I was hoping I could stop it at the last update prior to MM so I can root and wait to see how MM pans out. Is this possible? And what is the last software version prior to MM that I should stop at?
Normally OTAs will step through. 10o is the last update version before MM.
I unblocked the update files so I could update. I went into about phone and checked for updates and it started a download. I noticed it was 971mb which meant it was the Marshmallow update so I immediately blocked the updater files with the debloater to stop the update.
I'm on 10g and really only wanted to go to 10o and stop. Is there any way to get the rest of the KitKat updates through 10o? I'm assuming that if I unblock again and let it do FOTA updates on it's own that it will jump straight to the Marshmallow update again? I'm not ready to take my chances with potential bugs on Marshmallow and also to lose the ability to root.

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:
Galaxy S8 plus (AT&T)
Model#: SM-G955U
Android version: 7.0
Baseband version: G955USQS1AQF7
Android security patch level: June 1, 2017

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.

How to roll back to Oreo from Pie S8

With the new betas coming out there is defetly going to be a few people that are going to soft brick their devices installing them. Just like I did today.
Fortunatly I foundd the right firmware after a few hours of searching.
If you have flashed Firmware: ZSB9 from the Beta 4 and if for what ever reason you are locked out this firmware should do the trick
All you need to do is flash it with Odin and you will be back on the Sweet Oreo

This is for the S8 G950F
So nothing special is needed?
Just install oreo over pie like .... if I wanted to install stock os?

Downgrading my (unrooted) carrier locked At&t Note 8.

My note 8 had OneUI pushed to it about a week ago even though I kept refusing not wanting to while I was sleeping. It says my bootloader is v5. This is actually what it says (N950USQU5DSD3). My problem is that when I search for the firmware I'm wanting to downgrade to (the last oreo update possible for this particular phone) on Sammobile I can't find the one for At&t. I see ones for Verizon, sprint, etc. But nothing for at&t, which one am I supposed to use and where can I get it? This is going to be my very first downgrade/upgrade, really my first time doing anything like it on android. And I CAN do this right? There's nothing I should be aware of that makes what I'm trying to do not able to be done is there? The biggest reason I'm asking is because I have very limited tools to work with, I have a little 12" Acer aspire one (no disk drive) running windows 7 home basic, mobile hotspot from my wife's phone(the last software I tried to download and use came from xda out of a thread I found titled, "Stock Oreo N950USQS5CRF6 Odin*files*for AT&T*NOTE*8" it failed halfway through 2 nights ago during the beginning of storm, and the whole time it would only download around 32kbs so it literally to FOREVER! Only for it to fail halfway through. Was I wasting my time or was this in fact the firmware I'm looking for? If not, as I asked before, where could I find it?? Thanks a bunch for any help.

^^^^^^^Is this all I need? Do I need to follow this tutorial or a different one?? What version of odin, do I need anything else
Sorry for so much all at once, I really hate this update and want Oreo back.

Follow the steps from the above-linked post, and follow them very carefully. I did, and I was able to successfully downgrade from Pie to Oreo on my AT&T NOTE8.
I actually flashed the unlocked firmware, which has zero AT&T bloat. It works just fine for my needs. I don't think AT&T WiFi calling works on this unlocked firmware (I haven't tried - I don't use it).
Caveat emptor: whichever version of Oreo you choose (either the AT&T stock, or the unlocked firmware), we are stuck on the February 2019 Android security patch.
Only Pie gets the latest security patches. As long as you are ok with this, then proceed with the downgrade to Oreo!

A little off topic, but has anyone seen an AT&T security update for May yet? I'm still on April security, and it's basically mid June?
Tha k you I'll check it out when I get off work, I didn't know you could flash the unlocked firmware on a carrier locked phone
Let me get this straight. Can a locked bootloader AT&T SM-N9500U on Android 9, N9500USQU5DSD3 downgrade to Oreo? I thought this bootloader whould not let you go back.
I LOATH Pie and wan to go back to Oreo so bad, please tell me there is a for sure way. This is my first permanently locked bootloader phone and it's killing me not to flash an software I prefer.
I dont know I wish someone could tell me forsure whether it will work or not because now my phone is getting another software update notification so it's getting ready to force another update on me and I doubt after that I will still have bootloader v5. Can someone please verify whether my current bootloader (N9500USQU5DSD3) will downgrade successfully to back to oreo or not? I have the oreo firmware I want to use downloaded and ready to go which is (SM-N950USQU5CRL1). Can I downgrade to this without messing anything up?? Please I need a fast reply I dont want this new update forced to my phone and updating my bootloader to v5 where I can ever go back to oreo.

Yes you CAN downgrade back to Oreo. BUT you MUST go to a bootloader 5 firmware.

Yes you can go to that firmware. You will want to back up and allow it to factory reset. Be sure to use the modified version of Odin. Go HERE, post #2

Will a phone update with no sim and just on wifi?

I took off my custom rom and put a stock c432 european rom. The site said it was android 8.0 but when I checked it's 7.0 =/. When I check updates it says none but does it take time to get updates or do I need to put Oreo in order to get any updates? I'm hoping it get it to update to PIE eventually. Maybe I can put c432 Oreo, then flash the PIE files? Maye these are dumb questions.
