if so, which version or file should I use?
thanks in advance.
@josuemf: Downgrading is easy peasy, no issues at all. You can even go all the way back to Marshmallow if you want. Just flash a stock ROM EDL of your choice.

Hi, newbie question here. I just got my Axon 7. Unlocked the bootloader. Installed TWRP. Made full nandroids of stock and rooted firmwares.
I would like to flash the new Nougat update. What would be the best way to accomplish this without losing TWRP? and what is the correct firmware to use? ota? Also can nougat be rooted? Just dont want to brick my new phone. Thanks
No TWRP flashable file yet.....but I'm sure it'll be soon.
You will need to be on the Nougat bootstack, but you'll have to search for that info.
Hello, will this be possible? I can't upgrade to the stock Nougat firmware because I have unlocked my bootloader which is causing me problems, I can't upgrade with the instructions found here in XDA, and I'm running the latest official Marshmallow build. Thanks!
Same issue here
i think we can install nougat if we have cwm recovery. anyone know if already have this recovery?

I had no issues. I'd prefer an earlier Marshmallow build though. Doze mode in Nougat is so messed up that battery life went down a lot!!
Hi all, kind of a newbie query i want to install s9 rom by sac23 which is oreo rom, I want to confirm if I install this rom and later wants to go back to stock nougat will it be possible, If yes will it be via odin by downloading latest stock firmware from sammobile, or i can restore also from my nandroid backup of my nougat rom. My fone is now at nougat january security patch level build number NRD90M.G935FXXS2DRAA which is latest for my region. I also want to ask can i install sac23 s9 port directly over nougat by fromatting data, cache & system etc. Thanks in advance for the guidance
If i use twrp to flash device back from nougat to lollipop (stock), will be any chance in a future to install original updates (OTA?)
No!
How to do it? I have official Nougat. I've unlocked bootloader and installed twrp.
I've tried twrp, but can not find debloated flash rom. Some of guys are making downgrade with fastboot over youtube, but they downgrade back only previous version of android, for example from nougat to marshmallow, or from marchmallow to lollipop.

What will happen, if i try with fastboot way? Will I brick the phone?
So I really want to install a custom rom and I know I need to unlock the boot loader and flash it with twrp. But I been reading around here and it seems unlocking the bootloader on Oreo is not possible and the only way to do that is to downgrade to nougat... except I don’t really know how to do this on my device since as previously stated, the boot loader is not unlocked and I don’t know where the stock rom for nougat is even available to download from, or any necessary tools to download to be able to do this (I’m a complete noob). Some info of my device: A2017u, Oreo, B20
Help would be appreciated, thank you
I think you may need to go back to Marshmallow to unlock bootloader and install TWRP but I'm not on an A2017U so won't try to advise you.
I did revert my own A2017G from latest Oreo back to Nougat ok. Since gone back to Oreo. It seems to work when stock but once you meddle with it that's when all the problems start.
