Downgrade from Android 9.0 Pie to Oreo? - Samsung Galaxy S8+ Questions & Answers

Hey XDA Community
I've running Android Pie with a custom rom on my Galaxy S8 Plus. Is there a way to downgrade the System back to Oreo?
Should I flash a old Oreo bootloader or would it work with the Pie one? Or is this not a good idea?
What are your Experiences?
Thanks in advance!

Downgrading from Pie 9 to Oreo 8

I have upgraded my Samsung J4 which was running Oreo, to the latest Pie 9 android version! I have already downloaded the stock rom of Oreo version which I intend to flash with Samsung Odin on the computer! Are there any safety precautions that I need to take before downgrading? Thanks

Not really...just make sure its -XXU2 oreo. Otherwise you would get error and it wouldn't even flash anyways. I downgraded too...but back on pie with root now

The bootloader version in that ROM is version 5, "U5". If you can find a nougat or mallow ROM at version 5 or above then yes you can downgrade.

You can grab your official firmware from Sammobile and flash it using a PC with Odin. It's quite simple, just look it up on YouTube. :fingers-crossed:
