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:

Difference in firmware region

On my G920F I'm on a MM firmware (Netherlands PHN) but I want to flash the latest Nougat bootloader and modem. Now the PHN version of nougat hasn't been released yet on Sammobile. Can I just grab the Netherland (Vodafone) firmware and flash the bootloader and modem? What is actually the difference in the different firmware? I'm on Lineage OS 7.1.2 currently. Thanks!!

The Rom Im using is based on Nougat, so I was thinking to have a nougat bootloader and modem
G920F is international version of S6 and you can flash any region/carrier rom you want, without any problem!
As for the Lineage OS 7.1.2 ...., like you said....! Its based and not Nougat!
Differences can be founded on Changelists of each rom, but you cant see the detailed changes of each rom!

Need a new custom ROM for my device please

Hello everyone, I'm new to the forum but I've been following you for a long time. I have a Samsung Galaxy J3 2017 model SM-J330FN. I was able to install the android oreo update 8.0 although it has not yet been officially released using Odin. My question is: are there other custom ROMs, which maybe include the 8.1 update or are already customized? Unfortunately I could not find any more and I trust you that you are the guru of modding. I hope in your answer guys :fingers-crossed:
no one?

Downgrade from Android 9.0 Pie to Oreo?

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
