Hi, does anyone know if it is possible to downgrade S8 oreo to Nougat without a PC?
sorry, doubt it, not unless you did a full image backup with TWRP...
The easiest way is using smart switch, but un-register yourself from the beta program and ensure all your data is backed up as it will wipe the phone.

Hi all,
Im using an S7 Edge on Nougat.
I used odin and cf room (https://download.chainfire.eu/930/CF-Root/CF-Auto-Root/CF-Auto-Root-hero2lte-hero2ltexx-smg935f.zip) to root my device.
After the process finished, my phone rebooted but stays on the animated samsung logo.
I've done a search, and im a little lost - please help - any help is useful.
Thank you
I never used Auto Root but if you look at the chainfire page, and see the S7 Edge it is just for 6.01 and not nougat. I think that's the problem

I think that you need to flash the stock firmware for your country with ODIN. Maybe someone else can verify this?
Trying this and im getting Secure check failed (bootloader).
I'm scared and need help.. Anything?
Hi,
You have to flash a Nougat stock firmware if you wish to flash using Odin. Samsung bootloader (Knox) doesn't allow an official firmware downgrade, and IIRC that message you are getting happens when you're trying to flash an older version of Android.
Get a newer stock firmware and try again, or if you prefer you can just flash a custom recovery and flash a custom ROM (which may be faster and already comes rooted). Also next time search for a rooting method for your Android version, rooting uses of the system partition, that means if you try using an old method, there's a risk of something not working fine.
All the best,
~Lord

Hi Lord,
Just did what you mentioned, you were spot on - the older bootloader caused issues with the data partition so i lost all apps/data and had to start from a scratch nougat install.
All is working now - appreciate your help, both of you - i will research more in future.
My phone is unlocked and rooted. It wants to download the OTA but I know that Motorola says on their site you will have problems with the OTA. Should I download it or Should I flash a ROM.

You must be PURE stock to take an OTA update, or it will fail and bootloop... Flash a rom if you wish.
What i did was make a back up of everything just incase and then look up the ota version on your phone and get it in the rom section and look up twrp flashable OTAs and just flash it. you might lose root but its easy to get back if you flash magisk again.
You can found the right guide here:

does anyone have fastboot stock rom?

Of the current version? lol, no, we wish... we are averaging 3-6 months behind OTA releases for full ROM images, if we get them at all. Moto does not officially provide them, so they have to be leaked somehow, and sources are completely dried up yet, but it's getting there. :/
Hi. Can I get Oreo Ota for mi xt1670 with rooted device but locked BL? I'm on stock everything. Thanks.

You can't be rooted with a locked bootloader so your question is obsolete.
You can apply to OTA with an unlocked bootloader.
You can't if you're rooted or changed anything else in /system or /vendor.

Thanks for the reply. Very clear! Please I need more help. The thing is...I don't want the oreo ota right now. This is my mother's phone so I don't want any problem. Nougat is just fine for now. So I need to stop the upgrade notification spam. I believe I must unlock BL, then root, then freeze the upgrader app. Is that correct? I can't force stop the app. That's for now.
I've read bad reviews about oreo battery drain and other stuff. That's why I'm trying to avoid it.
If someday I want it, maybe will install some rom.
Thanks bro.
EDIT. Does this make sense? Or should I stay stock everything and take the ota/ignore the spam everyday?
EDIT 2. Another question. What happen if I take the oreo ota, and i don't like it. Can I unlock BL, root, install some nougat rom, as a pseudo downgrade?

Oreo ist absolutely fine, no problems with it.
I haven't heard of any issues like increased battery drain, for me nothing changed at all regarding battery and the rest is also working flawlessly.
It would be a lot of action to unlock and root the device just to stop the updater service.
If you don't have any other plans that need root privileges I recommend just taking the OTA (s).
If you want to run another ROM later you can always unlock the bootloader, install TWRP, root the device and install any kind of custom ROM, Nougat, Oreo or Pie. There are also TWRP flashable stock firmwares which make it easy to move between different stock versions.

That's good. A pseudo downgrade is possible. Thanks man. I'll think about it. And yes, the root privileges is just for stopping the updater.
Cheers
EDIT. Man, are you sure about this? Taking the Oreo Ota, and in the future unlock BL, root and install whatever rom?

Yes I am.
Just check some of the custom ROM threads, there are some that need stock Nougat as base but the most of them need Oreo. For custom ROMs there are no up/downgrading problems, that's only the case for stock firmwares.
And as said above, there are TWRP flashable stock builds that doesn't have these problems too and will bring you to whatever stock firmware you want, not just pseudo. (Here:
https://forum.xda-developers.com/g5...o-twrp-flashable-stock-builds-coming-t3830482 )
So if you're on stock Oreo after unlocking the bootloader and flashing TWRP all options are open for you. Just don't forget to make a full nandroid backup incl. EFS and persist before you flash anything.

If Oreo OTA update is installed. Any chance of a rooting option similar to the now successful PartCyborg procedure for Nougat?

Not until there is a factory rom for Oreo. There isn't one yet
I'm on 8.0 binary 3, its a nightmare for battery drain. Is there anyway to get back to 7.0 whether than be officially or a custom rom? Don't really care as long as I'm away from 8.0

Well it's possible to revert to Nougat via custom rom,but there is a chance you will loose IMEI,But before trying take a backup first just to be in safe side

Even using latest bl?
LineageOS 14.1 (7.1.2) works with binary 3 (tested by me), surely other roms work. Before making a backup in case you lose the mobile network (sorry for the english).
Could I go back to this

Why not ? We booted oreo using nougat bl. There is a chance it will stuck on splash screen or bootloop,but worth a shot.
Hi. I used a stock pie for a while and trying to get the root and twrp again. But as I see on this link There are no mention about data partition fix on pie. Does it just unnecessary anymore? or included in Kernel Patch?
Yes I do believe you need the fix if you are on Pie. When I flashed Pie I kept Oreo bootloader to ensure I could flash back to Oreo
