Unlock bootloader confusion - Huawei Mate 9 Questions & Answers

Hey Guys,
I have been googling for a while now and I seem to constantly come across conflicting and at times worrying posts which has very much left me stuck right were I am. I just recently purchased a Mate 9 in the hope I would be able to, like all my previous mobiles install a custom rom and tweak it to my specific needs. This however hasn't been the case.
Firmware:
System 8.0.0.046
Dataver MHA-L09 8.0.0.371(C34)
Things that have been tried:
1. No I didn't get a boot unlocker code from the Huawei
2. Yes I have contacted them personally via two different channels and both returned with a we are happy to give it to you, that's not an issue, but this code doesn't exist anymore.
3. DC-Unlock tool didn't detect my mobile in manufacture mode, in which I found another forum post stating to use HCU 3.22 client instead which worked to the point of detecting my mobile, but told me that the current security patch not supported.
4. Contacting DC-Unlock, told me there is no ETA on getting this patch level to work
5. I have read people downgrading to a previous version, unlocking and then installed the custom rom via HiSuite, this doesn't give me that option.
6. I have read people downgrading to a previous version, unlocking and then installed the custom rom via firmware finder.
6.1 Issues with this is that I seen someone claim to upgrade to version 8.0.0.3.75, which is higher then mine, which enabled the rollback feature, is this correct?
6.2 Issues with this is that I have read that gpu turbo has been enabled and many have warned that rolling back to a pre-gpu turbo enabled firmware will brick you mobile and would result in a motherboard needing to be replaced for nearly the cost of the mobile itself.
I am tempted to try another site which I can't remember the name of, which if you pay considerably more then DC-Unlock. at least if they can't get the code, would be refunded. but I think that site is down now as I feel they were playing on people who didn't know how to have done it for free via the Huawei site back in 2018.
So I want to know is there a safe way to unlock my bootloader I think my only option is option 6 but just want more details from others who have done it this way before, or have I pretty much exhausted all my option and just bite the bullet and upgrade to 9.0.1.187 and possibly further through the OTA update process and just enjoy the mobile for what it is and it's limitations?
Thanks again.

You can try the spoofing method here on xda I updated from 8 to 9 with that, as long as firmware finder says your imei is approved

Thanks for that, I can already upgrade to 9, my system updates app is just waiting for me to accept. The issue is that I don't want to go forward. I really want to go backwards, so I can unlock my bootloader first. I'm already at the stage where I have tried most if not all the safe ways to unlocking my bootloader, but with my currently installed android version I can't. The only way forward for me it seems is the firmware finder app and SD force flash back to EMUI 5 aka Android 7 to use DC-Unlocker to unlock it first, then that gives me the freedom of installing the official Android 9 or openkirin.
I just worried as some people have stated that if you attempt a downgrade after a specific point, something about GPU turbo being enabled in later firmwares, which will brick your mobile.
I just want to hear from others who have done this successfully or if it's not possible in my case.

Any UK users got Android Pay to work?

I'm unable to use Android Pay - I'm not rooted, the boot loader is RELOCKED but when I try and add my card I get the dreaded "Google is unable to verify that your device or software running on it is Android compatible" error.
So, I was wondering, is it the fact that I did previous unlock my boot loader or something else stopping me.
BTW, Vendor: hw Country: eu, running C432B170.
Cheers.
No joy either
Same problem here. Imported mine and have done nothing but update to latest version of official roms (tried a couple of different ones today as well) and I get the same error. No rooting, purposely held off doing so so I could try Android Pay. SafetyNet Helper says the "CTS profile match" is false. My wild stab in the dark is that it is something to do it with it being identified as an international handset or handset from a non-Android pay supported country.
Had a web chat with an Android Pay helpdesk monkey and they had me reboot and reinstall a few times. They've also had me send some screenshots but I'm not holding out much hope for a useful reply.

CTS. Just double checked.
Maybe it's the same thing as CSC for Samsung phones.
In case, this might represent the target market for that phone, and that market might not yet be allowed to use Android Pay.
I'm using the single SIM version, NXT-L09, I managed to add my card but when I tried to pay for something in store I got the unable to verify.... message pop up on screen.
It also fails the CTS profile match in Safetynet helper
Android Pay worked for me today
I gave safetynet helper another try and this time it said my device passed. Re added my card to it and then used it on a London bus.
Using a Mate 8 NXT-L09C636B170
I too am able to use Android Pay. It started working for me last Thursday. While I had an open support ticket with the Android Pay help desk I periodically checked to see if it had started working. Eventually it did. I was able to add cards, SafetyNet Helper passed it's check and I was able to make payments. Result.
The same day, Android Pay help desk got back to me regarding my support ticket (there had been some backwards and forwards with logs, screenshots and the like). They concluded that Android Pay would not work because my phone was rooted. It isn't and has never has been. They had me send screenshots of multiple root checkers that displayed that the phone was not rooted *before* they came to this conclusion. I guess they just wanted the ticket closed and that was the most convenient excuse.
I've put it down to enough people reporting handsets not working that the Google added more phones to the "approved list" and help desks don't know what they are talking about.
My build number is NXT-L29C636B180
Hm.. Well this was interesting to read. Thanks for the updates saying that Android Pay does in fact (hopefully) work! I'm going to to get the L29 International dual SIM version soon so I was curious... I'll update when I get it and test it out
Mine still doesn't work - I then tried upgrading to B320 and I can't even add a card now whereas before I did eventually allow me to add a card. I'm cheesed off with it. Bootloader Locked no root and no Android Pay on a L29C432B320

I've downgraded to B170 and now have Android Pay working.
The high level process was:
All done via the help of SRK Tool http://forum.xda-developers.com/mate-8/development/tool-srk-tool-huawei-t3369797
1) Unlock Boot Loader
2) Install Custom Recovery
3) Root Phone
4) Change to oeminfo and custom.bin eu (c432) - Even though I already was
5) Copy Full Update.app for C432B153 to dload folder
6) Flash stock recovery
7) Boot recovery and allow update to install
8) Factory Reset
9) Copy Update.app for C432B170 to dload folder
10) Boot recovery and allow update to install
I'm not sure how but following this process (although I've listed the steps from memory and not in front of my Laptop I did this on) I ended up with a Bootload LOCKED C432B170 and Android Pay works. I've not - nor will I update to and EMUI 4.1 version until they are released as OTA updates that my phone asks me to install
Android Pay was working fine on B103, I've upgraded to B321 via dload and now got pop up info that my device is incompatible with android pay. Any ideas?
Sent from Huawei Mate 8
Just one question
Hi,
Which recovery should I flash? the one for EMUI 4.1 or 4.0?
thanks
I believe Android Pay will not work with EMUI 4.1. I wish we were warned about this before we were allowed to flash to 320 or 321. No warning with the update links. Sucks!

Help with downgrade?

What i have: a brand new carrier unlocked samsung galaxy s7 sm-g930w8 - came with 7.0
What Id love to do: downgrade to 6.0.1 official touchwiz rom but rooted
What im reading: that the security patch is from february of 2018, which means the bootloader is too new, which means downgrading using odin wont work ( https://www.sammobile.com/forum/threads/36282-Does-Region-Matter )
... so what can i do? i bought this phone with the sole intention of downgrading, as ive seen that it is possible for that phone model (s7) in general
i hate the look of the newer OS. They took the touchwiz out of touchwiz which i loved, although mine is a rare opinion. I want the operation and exact feel of 6.0. the menus are simpler, the notifications area isnt completely stripped of features differing from total stock android. i hate having to pull down twice to see everything. I just really want that older look and feel, but all around, not just a theme.
is there anything i can do to either downgrade or fool the bootloader into letting me carry this out? is this a true limitation, or si that info i found false/old? and if I can downgrade, which build version should I use?
ive been looking here for versions
https://samsung-firmware.org/model/SM-G930W8/ but im not sure which region to go with, or if i can technically use any region
sammobile doesnt list that version anymore at all ( https://www.sammobile.com/firmwares/galaxy-s7/SM-G930W8/ )
https://mobiletech360.co/samsung-galaxy-s7-sm-g930w8-stock-firmware-rom-android-6-0-1-marshmallow/ there are a number of options here but unsure of the different numbers/builds. or if since its carrier unlocked, i could pick any?
I know most will think im silly for wanting to downgrade or caring that much about appearance, but silliness aside... is this even possible??
a while ago, i purchased an s5 mini, and downgraded that with no issues at all.... but its honestly been so long and i cant for the life of me remember the steps i took or if i needed to care about region codes or other numbers. but it did sucessfully work.... it was really built unwell/cheap, but it did work.... its also slower than my captivate glide which is still my current phone, until/if i can get this s7 working the way i desire.
any help and guidance is appreciated. If it is needed, ill be using it with a Koodo mobile sim.
well it is too new if its from DRAG or so onwards (those with U2/S2 in the file name) so no dice, you're stuck with 7.0 unless you want to upgrade to oreo. (and 7.0 firmwares prior to DRAG cant be downgraded to either, not that theres much point doing that)
btw this is the wrong forum to post this in

But this is the forum about s7? I'm wanting to modify an s7?
Which part of the file name are you referring to? Which file?
I would have thought all s7's are made at the same time, and so released with the same overall software, but it all seems so complex now. I've seen s7's running 6.0.1 stock so in my mind it seems they should all be able to...
Not sure what you're referring to with drag either? Does that stand for something?
I'm really hoping this can work somehow, its the last flagship before the edge models which was why I got it, and I love Samsung software up until 7 and 8.
My mom has an s7 as well, not rooted or anything that's too complex for her, but she did the upgrade to 8 and it's still got all the same gross appearance factors that I don't like about version 7. I got excited when her phone wanted to upgrade, maybe they had fixed some of the grossness. But, nope. Wish they had included an option even for stock based or touchwiz based appearance and menus.

go into about phone and tell me the last 6 characters of your build number
(i was referring to the PDA file in a stock firmware zip)
(Also i meant this should be in Q&A section)
Hello,
I can understand you and also understand what you want but Samsung installed a downgrade lock in their bootloader in early 2018,
if you installed this version you can't go back to an older version, I think that was in February.
You can go back from a 6.2018 version to a 4.2018 version for example but not to a 1.2018 version!
If you have a version of for example 12.2017, you can also go back to a version of 2016, so you can also go back to Android 6.01,
if not you only have the last versions of Android 7 or update to Oreo.
I hope I could help.

the last of the build number and the last of the baseband version are the same. But i did take a screenshot of it when i was thinking rooting and changing would be no big thing. figured that would be easier. i purposely havent even hooked it up to wifi yet or anything, said no to anything non essential when i was setting it up... on the chance it was starting up in version 6, and i didnt want it upgrading on its own.
also why would they block downgrading? It seems if anything blocking upgrading would be the way to go, to stop people from updating their devices before official software is ready, not just samsung but any manufacturer. in my head it seems silly to even need to root anymore... someone always figures it out, and cell phone manufacturers must know it. it would be nice if it were included, sort of like developer options, where its hidden, but if you know what to look for its there, and if youre not that advanced youll never find it.
if the bootloader is in fact locked and that is the main prevention, has anyone ever successfully unlocked it before?
ETA: Ive done a bit more looking around and there is alot around about frp and making you sign in to a google account in order to reset.... i have *not* needed and havent signed into a google account on that device at all... does that mean a downgrade is still possible though odin? Or, are these 2 things in fact unrelated...
eta #2: Did a bit more searching around, and it seems to be that in order to root your device, in the process it must unlock the bootloader? If that is still the case, would i be able to then flash the marshmallow stock ROM? Thats what i was looking to do all along, sorry maybe i should have been more clear about my planned method initially. Its a bit more nerve wracking as it seems rooting itself has gotten a little more difficult with that dm verity thing... but I definitely want root no matter which version im running. Ive had root on all my devices and theres no way im going back to a locked down OS (cant remove microsoft stuff for example), i need to be able to declutter beyond what factory allows lol.

TL;DR
your bootloader is currently on version 3, and you cant downgrade to marshmallow
see that "U3BRB2"? that "U3" means your bootloader is on version 3. i assume the marshmallow firmwares use bootloaders pre-version 3 so you cant downgrade to firmwares using bootloaders with version 1 or 2. (this is how it works for F/FD models and im pretty sure samsung made it like that too for the W8 models)
eta 1) unrelated
eta 2) F/FD/W8/S/K/L variants (basically all the exynos models) have unlocked bootloaders. only SD variants have locked bootloaders so it's just your misconception
So, it's literally impossible? Has nobody ever figured out a way to downgrade or mod the bootloader itself? It seems to me the rom makers wouldn't stand for this at all and would figure out a way around it...
I can see an old bootloader can't run new software, but it seems much easier for newer bootloader to run older software, isn't it? You can buy a windows 7 pc and install Windows xp on it much easier than you could buy a windows XP PC and install Windows 7 on it... It's just boggling my mind a little

Off course you can downgrade to Marshmallow. To unlock the bootloader, enable OEM unlocking in devlopper options. After flash TWRP 3.1.0 for Herolte and wipe everything from the recovery. Install any 6.0 roms on XDA for G930F then flash Magisk 17.1 to root and you're done. You can't FRP if OEM unlocking in devlopper is enabled.

You'll trip knox (which breaks features like secure folder, private mode, shealth and Sbrowser private mode) and lose the comfort of OTA updates if you do this tho. Not to mention that you can encounter signal reception problems because your flashed ROM is on marshmallow and your bl/cp is on Oreo or nougat. So I wouldn't advise this method as it may break so many things.

My progress: LG V20 H918/7.0+ FRP bypass in 2018?

After putting my FRP-stuck T-Mobile V20 away for a couple months, I was unfortunately surprised to learn that very little public progress has been made on the subject since my last give-up. I dedicated the last day to trying to figure out FRP bypass for my LG V20, and upon re-researching, I have...
1. Managed to downgrade my V20 to H91810j, though this version still has all exploits patched to get through FRP (to my knowledge).
2. Upon further research, I concluded that what I need is to successfully downgrade to H91810d, as it's the only pre-December 2016 update available (pre-December updates have un-patched exploits to be able to get into the phone). Unfortunately, this update was the one released on the phones stock from the factory, which made it next to impossible to find a KDZ file as they were't "pushed" to the general public.
3. Through researching countless other threads, I've come across this link (I can't share as I still haven't posted 10 times, can DM if needed for reference) which appears to be the closest possible file to the needed H91810d, except the download is a .ZIP that contains Boot.img and Modem.img, which I'm not familiar with using, and no .KDZ file.
4. Further research concluded that I could TWRP-push these files to a TWRP unlocked device, but because of the locked FRP, such a thing isn't possible. My last and final method (which I will try tomorrow as it's 8 AM and i've been trying to get this damned phone unlocked for hours and need sleep) will be one recommended on another forum, which is to downgrade, reset the phone, upgrade, reset the phone, and continue on until FRP is no longer on the device.
Researching into other devices proves that it's definitely possible, though the V20 (especially the H918 model at that) seems to have far less information available towards achieving this. After giving a selection of paid services a look as well, the majority didn't have the ability to unlock the V20 either, which makes me question what the V20 is doing differently from other devices. If anybody has any information that could help me or the community in the matter, please let me know!

Well for those trying, I have a phone on H91810q, and the above process (hardreset link) does not work. when getting to the step to allow unsigned binaries it will not toggle. I tried a few other approaches that might get USB enabled (e.g. via LDB in SVC mode, but it also failed to toggle).
Does any know if you can downgrade an FRP locked phone without USB enabled? e.g. using the process described in the thread http://forum.xda-developers.com/v20/how-to/step-step-guide-lg-v20-h918-unlocking-t3808258
Asking before I have to go find a windows box and spend an hour or so trying, in vain, if it is not possible.

Have you tried downgrading to h91810p first? H91810q might be patched as not to allow this method. Both h91810p & q are ARB1 so you CAN roll back before proceeding

WARNING to potential buyers of the Nokia 8

I just got done chatting with Nokia support (both chat and email) about getting the required unlock.key file that you need to unlock the bootloader for the Nokia 8, which they said they would unlock. First, a little background. The process Nokia wants you to go through to get the file is to download an apk of theirs which will analyze your phone a bit and then generate a code which you put into a form on their website to get the file emailed to you. Rather clunky but alright. I do so, but then I get an error when the apk runs. "Error messages: Device not support." Very well. I then talk to support. Chat had no idea how to fix it. Email fared just as well. I will copypaste the entire exchange. (Save for the original email I sent as I forgot to save it. Sorry about that.)

Thank you for getting in touch with Nokia Mobile Care. It's important for us to have you as our customer.
I can see that you are trying to unlock your phone's bootloader, you have already downloaded the app and you are receiving the message saying that "device not supported".
​
HMD Global allows the bootloader on certain Nokia phones to be unlocked, allowing for customizations. This feature is intended for developers only.
​
Once the device is being unlocked, it is no longer covered by the manufacturer's limited warranty provided by HMD Global.
If you have religiously followed the steps my colleague provided to you on the previous e-mail and after it you have received the message "Device not Supported" this mean that your device is not supported to have the bootloader unlocked.
If you are facing some issue with your phone, you can send it to a repair center, out specialists has the information on how to handle it. Note that Nokia only provides the possibilities to unlock bootloader to developers.
We hope that the above information is useful.
Any other question you may have are always welcome. Please feel free to contact us again.

^ This is not correct at all. At least for the Nokia 8. https://twitter.com/sarvikas/status/1045298106818949120
I have followed the prior instructions rigorously, but since the apk does not work, I must ask you for the needed "unlock.key" file. I am very well aware of the consequences of unlocking the bootloader.

Thank you for getting back to us. ​I'm sorry to hear that the previous solutions didn't make any difference.
I can see that you are not happy about the previous answer you have had. I understand that can be frustrating sometimes.
As explained before the allowing will depend on many factors, as market, for example. If you have the app running well, if you have tried all the steps to have your bootloader unlocked and still receiving the message "device not supported" there is no other reason than that the app itself is saying the device you are trying to unlock is not supported.
Did you tried to uninstall and reinstall the app? did you tried to restart the process?
Note that here we are a customer care for technical issues customer may face with their device, we do not produce the rules or the policy we just follow then. There is no other advise to you at this moment.
If you have any other question not related to bootloader, please feel free to get back to us any time.

So basically, to sum up, if you're thinking of unlocking the bootloader at all for any reason, steer WAY CLEAR of this phone. My phone may for whatever reason have fallen through the cracks perhaps, but a lot more people than me are reporting this issue. On top of that, I've checked my phone's IMEI to be sure it wasn't stolen or fake and it was perfectly fine and legit. Honestly, I hate that I have to post this message because the Nokia 8 actually has some features I like that aren't really on other phones, but because of this software travesty, I can't recommend it at all.
Nokia, if you're out there, this is a disgrace in both software and support. Please fix this.
Hi
I have the Nokia 8 TA-1012 but I have not tried to unlock the BL. I am currently on Pie so see no reason for doing so as I am happy with the OS.
As most people do not buy a phone to modify the OS I see no problem not recommending this phone for normal use.

While I didn't unlock through official methods, it might be good to figure out what models of Nokia 8 are affected. Maybe a specific model is affected?

It is not related to models, but instead to the build ID's the phones run. (Nokia software is completely generic) Back when Nokia announced the unlock process and the october security patch dropped, phones on october patch started to
report the same issue the OP has encountered. One or two weeks later (after some public outrage ) the app started working again, likely because Nokia added the build ID of the october patch to their
database of allowed versions.
The only solution that doesn't rely on Nokia might be to tear apart their apk and use a rooted phone or an emulator to fake the properties it reads, so the app thinks it runs on a security patch that is supported.
But this approach requires people to send their IMEI to random people on the internet so there are additional risks.

To downgrade without an unlocked bootloader, you need a full OTA image that is configured accordingly, directly from Nokia. You boot into stock recovery and sideload that image, and in theory you should get an Oreo system.
However: The only full OTA downgrade I have done so far was using the revert-OTA from the Pie Beta Labs build. That gives you Oreo with November / December update and AFAIK those builds are not enabled.
The only other full OTA I know of happened it May, and it might be possible to sideload that one to get a system that you can then update and unlock on September / October patch.
But I never used this zip file so I don't know if stock recovery would accept and flash it if you sideload it.
If anyone here wants to try it out: You can download the file from my nokia cloud folder (https://bit.ly/nokia-nb1 - OTA Updates/NB1-488B-00WW-B01-update.zip).
I would be curious about the results. (Only oreo users should try this.. When you downgrade a Pie install it corrupts your userdata)
(I am intentionally not posting a detailed guide. If you can sideload this, you also know about the risks of messing with your phones software )

I'm your man. With nothing left to lose. o_o Will report back with the results ASAP.
I'm back and with bad news. The update process via the recovery menu seemed to run into an error where it complained about the timestamp on the update zip being too old, but for whatever reason, it proceeded anyway. OK, wiped the data (what data?) and did a factory reset, now it's booting up. I check the system information to be sure and it is 8.1.0. Installed the apk. Ran it. AND THEN...
Device not support.
I'm gonna try this with the zip mentioned in frankoid's post and do another update again, but honestly, it looks like Nokia just wants to be an asshole at this point.
!!!!!!!!!!!!!!! SUCCESS !!!!!!!!!!!!!!!!!!
This update zip is what you need: https://android.googleapis.com/pack.../f9cb380bd9c2bf1b6ddebcab9dcf389843eb2d39.zip
It may be different for the TA-1012, but according to that earlier post, it does not seem to be the case. Nevertheless, just to be safe, here's the zip for the TA-1012: https://android.googleapis.com/pack.../139c94fd08f52fbd3b852ab4ef5c6515fffb784e.zip (I don't have a TA-1012 so I wasn't able to test this particular zip.)
So basically, to make sure there's no problems, make sure in the Developer's options on the phone that OEM unlocking is enabled, then put your SD card into the phone. Plug the phone into your computer. Copy the update zip that you need somewhere onto the SD card. Disconnect the USB cable. Shut down the phone. Then, while holding down the Volume Up button, reconnect the USB cable. You should see a sad android with "No command" displayed. Now release the Volume Up button. Then hold down the power button and then JUST PRESS once on the Volume Up button. You should be at a recovery menu. Using the volume keys, scroll down to the 'Apply update on SD card' option and select it. Select the zip that you copied over to the SD card earlier and then let it install for a while. It will probably pop up with a 'timestamp too old' error, but just ignore this. The update will install anyway. Then once it's done, do a factory reset on the phone and then shut down. MAKE SURE THERE'S NO SIM CARD IN THE PHONE.
Now that's out of the way, just click through the first-time setup screens but DO NOT ENABLE WI-FI or any kind of internet connection. We don't want the phone to update itself back to Android 9. Now plug the phone in again. Copy the bootloaderunlocker apk from Nokia's website onto the phone. Install it. Put in the email address you want the unlock key emailed to. Then voila! You'll get the verification code. Put it into the form on Nokia's website and you'll be emailed an unlock.key file. From there, the site will tell you how to proceed.
Thank you apple boy for this topic.

Great to hear that you got it working! My zip likely not worked because it just throws you back half a year (where official unlock didn't even exist) - you would have to update until you find a security patch that works.
But if November patch worked for you thats great! Since the May OTA worked for you that also means that people could choose to use the unofficial (paid) unlock method so Nokia doesn't know about whether they are locked or unlocked (warranty reasons).
Those OTA zips are model-agnostic btw. Whether they say TA-1004 or TA-1012 doesn't matter, they are the same. Only google makes that distinction on their servers, the software doesn't.

Did you touch the option in the past at all? If you did, it will be greyed out. As long as it's switched on though, it's fine. (I heard it will "ungrey" itself after a week, but there you go.)
No, did not do anything and it is off and greyed. I don't think it will magically ungrey itself. I did however download that unlock.apk and sent out email and pin, now waiting if a reply will come with the unlock code and procedure. Its been a few hours and no reply, so perhaps that's not working either.

I'm assuming you have a brand new TA-1004? And yeah, you should have gotten back a code long ago.
Try some of these options. https://www.theandroidsoul.com/how-to-fix-oem-unlock-greyed-out-or-oem-unlock-disabled-problem/
It could be though that it's just been flat out disabled due to region or whatever. If the solutions in the above link don't work, try downgrading back anyway and then using the apk as explained in an earlier post of mine.
It seems to be a case of "flat out disabled". I did a factory reset already and this setting won't change. I actually bought 2 of those phones and on both is the same.
How do I see or find out what region they are for?
And for the booloader, seems I have to go the old fashion way now...

Mine has same problem and I've also been through similar online-forum attempts to help.
Model: TA-1012
Hardware version: 3.1
Patch level: 1 Jan 2019
Build No: 00WW_5_11A, 00WW_5_110_SP01
Downgrade your phobe and you can unlock, i have the same phone and this is what i did. I downloaded my phone firmware,i place the update file on my external sd card, i reset my phone to factory stock, i shut down my device an while shut down i press vol + and plug in my cable, i wait for the no comand screen and press power while holding vol up and get in recovery where i update from sd card and boom oreo

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.
https://forum.xda-developers.com/at...n950u-stock-n950usqs5crf6-odin-files-t3821222
^^^^^^^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
