You can't, there is no way to do it by stock firmware. you can install tWrp and then load Oreo custom rom and try to flash modem and bootloader for it if that possible.

Install stock recovery back, then flash stock nougat zip.
no wipes needed.
you can download the ota from asus support site.

On which rom you are?
If its some emui just search somewhere in here for firmware finder tutorial i used it to update to 380 (i had root and unlocked bootloader) and if you are on cm you shoud have backups (atleest if you did everything like all tutorials said) and just restore back if you don't know search
If you are on any other rom look up post from which you flashed it... Usually there is written how to get back
go to huaweis support site and find your phone. under downloads they have stock rollback package and stock firmware. download both and you will find a guide inside the downloads. then you're back to stock
Hi,
Right now i am on stock EMUI 5.0. My version is VNS-L21C432B370 but i have battery problems which i think B380 can solve but since i am rooted and with unlocked bootloader i cant OTA update.
I think getting the VNS-L21C432B380 full ROM i can update with 3 buttons method but i cant seem to find that ROM nowhere.
Can someone help?
Thank you
Hey,
I have the VNS-L21C432B380 full rom (stock) with an unlocked bootloader and unrooted. If there is a way to backup it without unlocking b/l and rooting, PM me and I'll get you sorted. Cheers!

AFAIK, it's not possible to downgrade with a locked bootloader.

Unless you have a Chinese variant, you cannot unlocked Snapdragon bootloaders on the S7.
I've went back and forth between Nougat-MM several times. You can't go back earlier than PH1 due to the bootloader being locked, but that gives you the choice of 2 MM firmwares, PH1 and PI3.
Can anyone point me to directions on how to roll back to Marshmallow?

That has the resources you are looking for. Just grab either the PH1 or PI3 firmware and then do a normal Odin flash. You will be downgraded to stock MM.

i just did this in my s7 edge for verizon. Tried to flash the unlocked firmware and it failed. It woudlnt' boot afterwards. (it was first on 6.0.1). I then accidentally flashed a nougat stock rom. After this, I flashed a verizon 6.x.x fimrware and then the tmobile firmware. ALl through ODIN of course. I thikn as long as it works through ODIN, you are fine. It may take a lot of trial and error though

Upgrading to EMUI 5 from a custom EMUI 4 ROM??

Can anybody explain to me or point me in the right direction to upgrade my firmware to EMUI5? I can't figure it out and it's killing me. I'm currently running a melticulus RR install which has recently started playing up so I want to upgrade to a 7.0 ROM and to do that, I apparently need to upgrade my firmware to EMUI5
Thanks
Use firmware finder

Hello,
Yes man you need to do that..
I'm on EliteRom by HassanMirza and as you came from RR MM 6.0.1 whit Meticulus Recovery TWRP-3.0.2.0-hi6250-v4.zip.
So i hope you've done your Dump backup+Nandroid backup as explained as well.
Starting from here u need to follow steps in the Meticulus site in the FAQ section of TWRP download page.
Well done.. now flash the Stock Recovery and let it upgrade..
Enjoy

How can I downgrade from Oreo to Nougat? (Want to unlock boot loader)

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.
