Oreo downgrade to nougat - Samsung Galaxy S8+ Questions & Answers

Probably already answered but if I install the Oreo OTA once it comes to my device will I be able to downgrade to a previous nougat build later? I heard somewhere that Oreo has a different bootloader so we wouldn't be able to downgrade to nougat if I wanted to.

Help for update for news roms Oreo

I was in Nougat and always updated my Mate 9 downloading firmware by FF and used the tutorial here script and HWOTA folder,
I installed Oreo using the script but now when trying to install another newer Oreo firmware, it is not possible because TWRP does not install anymore.
I do not want to downgrade. I want to be able to upgrade to the newer Oreo firmware. How do I do it now? Am I stuck on this beta rom forever?

Still confused about the new firmware you are talking about, what is meant by day 18 and 27, are the firmware versions are different? I am also on oreo MHA-L29BC636 321-logs

Downgrade oreo to nougat without loosing root?

Hi!
I have a rooted galaxy s7 g930f running stock oreo (that I updated from nougat using Odin).
I'm getting fed up with all the bugs on oreo and would like to go back to nougat.
Is there any way to do that without loosing root and my data?
Thanks in advance!
Technically it's possible, but downgrading from Oreo to Nougat without wiping is going to cause more bugs than you probably have right now.
Your best bet is to backup everything, flash Nougat clean with Odin, and re-apply root.

Hi!, i installled Oreo on my S7 g930f but i now have one problem. The ROM binary from oreo is 3, and Nougat use 2, for this reason i cannot to downgrade to nougat. Recently i installed TWRP and a custom Oreo rom.
Its possible to install a custom Nougat rom through TWRP?
Many Thanks!
You should be able to flash a Nougat ROM via TWRP, but you'll have to make sure to flash the bootloader and modem back to Nougat if the ROM doesn't include it as part of its install.
I've gone between Oreo and Nougat a few times, granted my roll backs were using a TWRP backup and not a nougat flash.

Have you some tutorial teaching how to make this downgrade.
After the update my mobile is Just Call of Emergency, and the patch to solve this just works at Nougat.
