Unless someone knows a better solution guess i need some help to restore back to Factory image
Here you can find the original firmware files. Latest one will be Android 8.1 Oreo. There will be no security patches.

It is... Flash it via TWRP after wiping your device and profit. Think about that´s a factory image with own recovery, lost root etc... And sorry for my ignorance - but as a senior XDA member you should know how to flash original firmware...

Long story short, I got pissed at Moto and decided to unlock my bootloader, flash TWRP, and flash a custom ROM (Alberto97's AOSP 8.1). While the ROM is working fine, eventually, I kind of missed the stock ROM, and decided I want to go back (Oreo). Keep in mind, though, I don't want to relock my bootloader as I will flash TWRP and root my device after going back to stock. How do I do this? I do have the Oreo OTA zip with me (Build no. OPN27.76-12-22), if that matters.
When you never were on stock oreo, you can easily flash stock firmware with February security patch (it's 7.1) and then update with the Oreo update zip you find in the forums. Then you can flash TWRP again.

Bro, you and I are on same page. I also rooted my device when I was on stock Oreo and forgot to make a backup of stock Oreo (cuz I'm stupid). I talked a lot to other members and only option that is available for now to get back to stock with boot unlocked and OTA support is wait for Fastboot flash files for stock Oreo. Stock flash files will return your device to original state. I hope Oreo frimware would be available soon (about couple of months). I also want to get back to stock and guess what? I am also using AOSP by Alberto and it's working just like stock, no problem and bugs (there is some data connection bug but I use wifi all the time so it doesn't bother me) so far. Only problem with this ROM is safety net but I don't even use apps that requires safety net certification so I'm good with that too. Basically, it is a perfect ROM for me.
And don't try to back flash if you want to get back to original state, it is true you can still flash 7.1.1 but no guarantee, I just heard from someone but I never tried because I don't want to take risks and even if you got it running 7.1.1, a single OTA will brick your phone for sure. So wait for Oreo frimware, that's the only way and by the time enjoy AOSP.

You'll get back to stock for sure but bootloader will still be unlocked, the only way to lock bootloader is through fastboot flashing of stock ROM. Moreover, TWRP backup contains personal information so not many want to share it but if someone kind enough to make a backup after doing factory reset so it will not contain any personal information then it will work.

Why would one still want to relock the bootloader? It's to my understanding that unlocking it voids your warranty, and I've also read somewhere that even after relocking it, the warning persists.
By the way, have you checked my PM?
Hi guys, in my case I updated from Android Nougat 7.1.1 to AOSP 8.1. now I want to go back to stock rom 7.11 and after that update to Oreo by OTA. Should I only apply Stock Rom 7.11 by RSD Lite??
Thanks in advance

Link for the topic with the Oreo stock fastboot ROM. https://forum.xda-developers.com/moto-z-play/how-to/guide-relock-oreo-bootloader-to-stock-t3784621
1.67 GB in size.
So I recently got my honor 7x and I got the bootloader unlock code today. I unlocked the bootloader, installed TWRP and downloaded a custom ROM like I would on my other devices. I'm on EMUI5 and I assumed flashing an android 8.1 ROM would be possible so I wiped my internal storage. After that I tried flashing the rom in TWRP, which gave me some error about the zip not being in the right format. Then I flashed the rom in ADB but the device wouldn't boot up. I'm sitting here with a formatted phone with TWRP on it and a huge headache.
Could someone please help me and tell me how to revert back to stock or how to get a rom back on my device? I have the BND-L21 variant and I was on EMUI5. I'd really appreciate it because I'm kind of freaking out rn.

If your still on 5.1 you can't update like that you will have to perform the manual update found here https://forum.xda-developers.com/honor-7x/development/manual-update-to-oreo-beta-emui-8-bnd-t3764509 I think those files can work for your device but try to get the official Oreo update files and proceed

I have been trying to get an answer for quite a while and no one has replied so I'm going to make my own thread.
I have a Samsung Galaxy S9(SM-G960F) 64GB, Running 8.0 Oreo and the current build number I am on is G960FXXU2BRGA_G960FOXM2BRGA_BTU.
My issue is that I cannot flash any custom ROMs onto my phone without it getting stuck on the "S9 secured by knox" splashscreen on boot. It does not bootloop or anything it just stays on that screen.
I have heard many things about the fact that BRE5 vendor is needed to flash custom ROMs but I cannot find anything anywhere on how I get this vendor.
Can somebody please help me?
Thanks

Not sure what your specific issues is....but latest flashable vendor files are on this site. Plus....look for Soldier9312 development Discussions in Cross Device Devolpment here on S9 Forums.

So if I installed BRH4 that would allow me to flash ROMs? At the moment I can only assume its the build that I'm on that is stopping me from doing so

You are not giving much info. Start over. If you updated firmware, then you need to flash a ROM that is also using latest firmware. Just flashing a firmware update is not going to fix anything. Don't know what else to tell you. From your first post, you were on BRGA. I'm guessing latest firmware not compatible with your current ROM.
When my setups for whatever reason are in a really bad state, I do the following:
From TWRP recovery, I use the format tab and answer YES to the Format process. I then go back and under advance wipe, click on all the caches, data, system, and even internal storage. You can try without wiping Internal storage, but if you were coming from total stock, then I would also wipe that. Now flash a ROM and you should be fine. Not here to tout any one ROM. I have used a slew of them and again, not here to promote any single ROM as "the best".

So I'm now back on the stock firmware that I was originally on which is BRGA. Whenever I flash a rom I always format data just to be safe but I tried flashing RR and dotsOS and the BH4 rom that the other member suggested and none of them worked. I downloaded the stock firmware from sammobile it's the UK one

AOSP ROMs IMHO have issues. Use a Samsung based ROM, and generally no issues. Your choice. I do NOT push any one ROM. I currently am on TGP...The Galaxy Project you can look up in Cross Device Development.

Process should be same but i would not recommend, as several people have reported bricked phone while reverting from later pie versions to oreo.
I myself tried it when initial pie was released and did not face any issue.
Another challenge would be to find oreo raw firmware, there is no official link available as per my knowledge so have to be careful before downloading from 3rd party site.

So far as I know, you can't downgrade the Binaries. But still u can manage to find someway to leave A11 and back to whatever A u want since customs ROMs ( based on stock ) are seems enough

Flashing Custom Recovery and/or ROOT on A50 is quite different with few extra steps. Do the searching in our forum, u'll find the information u need.
P/S : Always read carefully ROM's Install Instructions, it cover all the info u may need!
