I coasted by for months not upgrading my note 8 because I heard bad things about pie on note 8. Well this morning I accidentally hit install now instead of backing out of it. Can I downgrade back to the final last version of oreo stock firmware? Here's my software info.
Can I and if so how to downgrade to tmobile note 8 oreo? https://imgur.com/gallery/puzXavA
Thank you very much.

I don't have the "how to" answer for you. However, since you aren't on AT&T's locked bootloader, you can downgrade to any stock ROM you like. In either case, backing up your data, is a must.

You can only downgrade if you use the same bootloader version you're on bootloader version 5 so you cannot try to flash any bootloader version below 5 it must be 5 or above! @Anonymously_Unknown is incorrect when he stated your bootloader isn't locked because your bootloader is locked unless you have the F version which you don't have. You have the American version not the international F version. Also you need to use the newest version of Odin available.
Thanks for the clarification

Hi,
I have Note 4 N-910T with Kitkat baseband version N910TUVU1ANK4 and the phone is fully unlocked i.e. I am using it outside USA and on other network sim not T-Mobile
I want to update it to
EPJ2 6.0.1 Marshmallow BL and Modem (as of October 2016, Latest)
https://drive.google.com/open?id=0B6...WRvVmJWTzItS0E
My question is
1. Should I first flash TWRP on phone and take back up and then flash the Marshmallow firmware ?
2. Will my phone lock to T-mobile network after update ? What If I flash some custom Marshmallow ROM, will it still lock ?
3. If it is locked or something bad happens, can I safely restore the TWRP back up I created ?
Please help me
Thanks
Aiden

You cant flash via twrp
First you have to flash 6.0.1 full stock firmware via odin to get marshmallow bootloader/baseband.
And dont worry it will not sim lock the device
After that you can flash twrp and flash any 6.0.1 custom rom
Keep in mind once you flash lollipop or marshmallow you cannot go back to kitkat. Your bootloader will be locked and impossible to run kitkat again.
And also your twrp backup of kitkat will no longer work.
I suggest you stick with kitkat cuz it's best for note 4 till date.many users are pulling their hair to go back but they can't. Marshmallow is good in performance but kitkat is best in battery life and speed.
can i down grade from marshmallow to lollipop im on epe3

But I was able to downgrade my W8 N4 from MM 6.0.1 to stock Kitkat 4.4.4 by Odin 3.09 without any problems, It doesn't lock the BL, I am not sure for other models but at-least mine BL was not locked.

I recently made an insurance claim for my phone and had to send my unlocked firmware note 8 back. Problem I'm having now is, I cant get the new one on an unlocked firmware. I keep getting errors in all the Odins I have. I dont know much about the v4 bootloader or when it was locked. I was able to gi back to Nougat on my old phone and then upgrade back oreo. That was in August though. Any help would be appreciated. I cant stand this ATT ****!

You can only flash the same bootloader v4 firmwares or higher from now on. No downgrading possible to bootloader v3 or below!
Can't even go back to Nougat (that was on bootloader v3 and below)!
If you are just need the unbranded firmwares look for the ones with the bootloader v4.
Eg N950U(U1)SQS"4"CRH1. The 4 in "" is your bootloader version.
If you want to root or go back to nougat then you'll need to talk to ATT for another phone that's on bootloader v3 or below.

Could you possibly link me the the firmware I do need? I would really appreciate as I'm stuck on this current firmware. I've looked and looked. I'm just unable to find the right firmware. I suppose it's possible I'm not getting the right one. Idk.

The easiest is to use SamFirm to download the firmware. Then use modified ODIN 3.13.1 to flash it.

I figured all out! I managed fo flash the latest unlocked without any issues.
Hello,
Would someone tell me if it was possible to downgrade to Oreo if your phone came with PIE preinstalled? I was told it was a matter of the bootloader staying the same. If true, what would happen if the bootloader changed after I downgraded to Oreo and needed to reinstall? Would I be out of luck?
Thank you!!!!!

The bootloader cannot be downgraded unfortunately. What model device do you have? That's the first thing we will need to know before proceeding further.
I done it before on s9+ but i have read on some sites, that bootloader must be the same, my bootloader has the '7' bootloader but want to run a Oreo rom (exykings oreo light rom) can i just flash after clean flash, or is it not possible?
Thank you

Not possible, you already answered yourself because you know you can't downgrade the bootloader and you can't run Oreo using the Pie bootloader.. If you're on an F version of the phone then you should be able to flash twrp and then flash whatever you want I'm assuming.

If you want to downgrade from Pie - N950FXXS"7"DSG1 to Oreo - N950FXXS"6"DRE2 you CANNOT do it because the bootloader ver "7" won't allow itself to be downgraded to lower versions "6",5,4,3,2, and 1! You're stuck on PIE!
(The Number in Quotes is the bootloader version. )
If you root your phone you can try to see if the custom oreo rom will boot with bootloader version "7" by asking and searching in the custom rom (that you choose to run) thread.
Root does come with a few cons like permanently tripped knox, No Samsung pay, and no knox related apps so read up on it.
(You will lose secure folder and Samsung health if you go back to stock firmware! But if you stay rooted and on a custom rom then you'll have access to Samsung health and secure folder (Devs found a way to get secure folder working! Check the note 8 roms forums for info on it.)

Read @BluePhnx post.. I already told you that you can't downgrade but you can root and flash twrp and then flash whatever roms that the devs have made for bootloader version 7! There's really no going back!
Before trying anything on my phone thought I wanna ask first.
I have an N960F, Exynos obviously; but I want to downgrade from Android 10 Q. I learned that I cannot flash official firmware via Odin that is based on an older bootloader version, say Oreo or Pie.
Would unlocking the bootloader change this case and allow me to flash Oreo again?

Sadly, no. Sorry man, the unlocking of the bootloader only allows for non-official binaries to be installed, such as TWRP, but nothing will let you go backward in bootloader versions. Sorry man
post up your entire firmware version so we can look around for ya and hopefully find a pie firmware for ya
