Odin to downgrade Samsung galaxy note 8

[mdxii]

Hi,
I have updated my unrooted note 8 to the android Pie but unfortunately I didn't like the new awful UI also I missed some good features in android Oreo. So, is it possible to use Odin to downgrade unrooted note 8. I'm not interested to root it, just want to downgrade it to official Oreo.

One more question, I even liked Android Nougat than Oreo. So is it possible to downgrade from Pie to Nougat using Odin without rooting?


thanks

You can go back to oreo as long as the bootloader is the same.
You'll have to do a factory reset though.

eg.
Oreo firmware: N950FXXS5CSA2
PIE firmware: N950FXXU5DSA2

Notice the 5 before "DSA2" and the "CSA2" that's the bootloader version. So since the pie and oreo firmware has the same bootloader version you can go back to oreo.

You can NOT go back to Nougat different bootloaders.

eg.

Nougat firmware: N950FXXU3BRA8
PIE firmware : N950FXXS5DSB2

Notice the 3 before "BRA8" and 5 before "DSB2" they don't match!
So the bootloader version 5 will NOT downgrade itself to version 3 therefore Odin will give you a failed error message.

What is your csc?

Spain is PHE in multi-CSC OXM

Vodafone is ATL in OVF Csc firmware.

If you used home-CSC and it fails only option is to use the CSC file (this will delete data so backup first.)

The multi-CSC oxm doesn't have ATL csc inside so you'll lose any carrier specific features (maybe???) So do some research first.

CSC Questions

Hello everybody, I've found myself in the position of needing to downgrade from Pie back to Oreo also.
My question revolves around this "MYSTERIOUS" Samsung "CSC" designation, and the difficulties in verifying what I have vs what I NEED

I have an unlocked SM-N950U1 which is currently running on the Verizon network in the United States

I do NOT have any of the Verizion specific features, ie.... "My Verizon" or even "Verizon Visual VoiceMail"
the phone has also been on the AT&T network previously again with no carrier specific features there either.

Since the "secret code" for the dialer didn't work to reveal my CSC, and there is no carrier software version entry in my about phone software information to reveal the CSC either, I downloaded one of the generic "phone info" apps and it reports VZW as currently active CSC on the CSC tab, but then on the firmware tab in the CSC version location its reporting "N950U1OYM5DSC1" and I have found zero reference to an "OYM" CSC anywhere.

I have downloaded both the PIE and OREO variants of the "XAA" firmware for my Note 8


Does anybody have any idea if this is going to be the correct firmware to accomplish this downgrade without bricking this darn thing, I have no interest in root nowadays because the minuses out weigh the pluses and I really don't want to trigger knox and loose google pay or any of my banking apps, but I really do use and need to use the call recording capabilities that still worked in Oreo, and not anymore in Pie

Thanks in advance
Dan

Hi, i just came to this conclusion! i am currently running N950FXXU7DSJ1 and odin always gives me error when i try to downgrade. no matter newest or older version. so there is no possible way to downgrade?

What if i unlock bootloader(if its possible for currently last version), change to custom recovery and install any custom rom(nougat?) and maybe flash bootloader via custom rom also? will this option be possible at all?
