Downgrading From Oreo to Nougat for Root? - Samsung Galaxy S8 Questions and Answers

Hi, I'm trying to root my G950U1 (v5BL) running 8.0.0. I understand that Oreo, as it stands is unrootable. However I've seen multiple post explaining how a downgrade to Nougat can be done through Odin. Although, no one every mentions this when someone asks if they can root their Oreo S8.
Wouldn't an easy workaround be to downgrade to Nougat then root using this method?

Am I missing something here?

The nougat kernel we need for rooting from Samsung is only in a nougat form. The Oreo kernels are not permissive. The combination file we use for rooting is for every bootloader version the kernel we use for rooting is in the combination file. Which again is nougat.

Root Sm-G930P on Android 7.0 (N) PLN

Hello,
I am running an SM-G930P with Nougat PLN firmware. I downgraded it to PK1 Marshmallow firmware to root it, and used this root method: https://idoneapps.com/forum/index.php?topic=616.0
It worked perfectly. However, when I tried to use the Nougat update file, it said it was corrupt. When I tried to root it in Nougat, it began bootlooping. Is there any way to root it in Nougat? All I need to really know is how to install TWRP.

There's not a way to root on Nougat yet, especially since it's on a beta firmware. TWRP isn't available on U.S Snapdragon Galaxy S7's as our bootloaders are locked.

What if I downgrade to Android 6.0.1 PL6 firmware, download the firmware file and flash it via FlashFire?

You'd want to downgrade to PL6 and the flash the unlocked PL2 to root, but TWRP still isn't possible.
as many have said. ZERO TWRP UNTIL BOOTLOADER GETS UNLOCKED (which probably won't happen) /thread closed

Planning to buy G935W8, had a few questions

Looking to buy this phone soon but I was just wondering about a few things. Im buying the canadian variant G935W8.
1. Can this device be rooted on nougat as well or only marshmallow? Im buying it brand new so I think it will probably be running the latest firmware.
2. Is there any issues with unlocking the bootloader? Is it neccesary to do so if you want root and custom roms?
the bootloader is not locked on the w8 as its the exynos variant and yes nougat can be rooted its the same as 935f

Thanks. Also another question I had. If the phone comes with marshmallow and I root it will I be able to install nougat roms directly or will I have to update the bootloader and modem? In that case would it be better to update it to nougat first and then root?
Updating your phone would cause you to lose root anyways as the file structure on nougat is completely different then marshmellow.
Rooting also prevents OTA updates, so you would end up having to install nougat manually.
I suggest you upgrade your software then root it. You can use systemless root from magisk. Using TWRP just flash the latest magisk file and you are rooted. The file will automatically root your phone as part of the installation process.

If you get it with MM (highly unlikely) just don't do anything and you should get an OTA notification otherwise you can download Odin, google it as I don't have a link and nougat from here https://www.androidfilehost.com/?fid=457095661767144483 and you can flash it yourself now rooting is a little different then it used to be do a search on the s7 edge for the info on that
the reason is yes you will need to download the BL not sure about modem but you might as well do it too
I just rooted my G935W8 running 7.0 by following the instructions in the first half of this video.

Sprint S7 on Nougat "QAA". Can I downgrade for Xposed?

I'd really like Xposed, which means downgrading to Marshmallow. I just purchased the device and unfortunately it was Android 7.0 out of the box.
So can I downgrade to Marshmallow safely? Looks like I'd need to downgrade to "PE1".
What if I can't get to MM? What's the preferred route for root on Nougat? The "U" firmware?
Thanks all!

Root on marshmallow is a little unstable and I'm not sure it is worth the downgrade. What do you need root/ xposed for? Some modules put the phone in a boot loop because of the root method we have.

What root method are you using? I've been running a rooted MM s7 for about 8 months with very few issues (with occasional flashing of other firmwares in an attempt to root them). It's rock solid, and very few modules are incompatible, and that's due to the nature of our rom, not our root method. (Android N-Ify builds past v 0.2.0 for example).

I have upgraded my phone(sm g935a)to Oreo i want to downgrade it

Kindly guide me someone i want to downgrade to marshmallow on SM G935A .. i have tried the apk1 rom but failed to flash please help...
You'll get used to Oreo, it's pretty good so far.
Assuming it's still on bootloader 4, you can downgrade to any firmware build using BL4. I don't recall off the top of my head if there was ever a MM build that used BL4, but that's the restriction. Anything else will either not flash or brick your device. You will need a modded version of ODIN to do the downgrade.
why do you want to downgrade?

G930V 8.0 Downgrade?

I have seen some discouraging posts regarding rooting the S7 on 8.0, but can It, and it's bootloader, be downgraded by Odin-flashing a 7.0 firmware?
