I think that it should be possible with Odin but honestly I never done it before so don't know. By the way, is the black mode feature implemented it this version of Pie in the toggles or in settings ?
Because I read someware that the initial version of this black mode or night mode or however it's called is not fully implemented like the final version should be.

First try clear cache in recovery mode maybe can resolve. also try to update apps with play store or with galaxy apps because some apps must need an update to the pie version.. After that if all is worthless, maybe a factory reset will resolve Sometimes corrupted data may do this after an update specially after a big OS change like this.

Hey let me know if you succeed, as I'm thinking of downgrading as well. ONE UI PIE-9 isn't all it's made out to be Oreo 8.1 rocks!

Downgrading is no problem atm, i downgraded from CSA2 to ARL3 . I flashed the non-home csc though for a factory reset.

I am a complete newbie... with that said, I HATE the new android Pie. Can someone help me downgrade back to Oreo? I'm reading the thread and I have no idea what you people are talking about. :(

You need to download SAMFIRM.EXE ---> Get SamFirm.exe https://forum.xda-developers.com/gal...mware-t2988647. Do you know your old firmware ? Luckily i had a screen shot of my old firmware i'm back on Oreo 8.1 way better :D Or what's your Note-9 Model number ? Or Where did you purchase your Note-9 from Country Supplier Sim Free Etc ?

Im sorry but the page of the link you provided could not be found. Model # is SM-N960F/DS. Im pretty sure I was on Oreo 8.1, I just recently bought this Note 9 in Thailand from the official Samsung Store.

These are all the firmware's i found for your country as there are 2 provider for you country Thailand.. (SEE PIC) i got a feeling you will be on (THL) i could be wrong man I'm not 100% sure.. i hope someone answers you as i am kind of guessing, I don't want to mess up your NOTE-9 for you!

i heard somewhere flashing wrong firmware, can make you lose OEM LOCK!! Why not try this launch SAMFIRM.EXE and input firmware from pic or try this first launch SAMFIRM.EXE and select auto to see if it picks up the firmware you need to download Oero 8.1!!

I have never used ODIN before and wanted to know if I need to be rooted to be able to downgrade from Pie to last Oreo firmware?
Also if doing so will cause a factory reset and will I loose the data.
Thanks.

No root is needed to dowgrade!! You will lose all your data! So make a back up before you proceed!

Will that affect Knox and Secure Folder feature in anyway?
If not, then this seems to be the Samsung approved official method of flashing firmware. Is that so?
Thanks

No Knox will stay 0x0 as your flashing official firmware.. Root and Roms trip Knox and secure folder S,Health etc. So you can flash away regular firmware without any issues!

I'm hoping someone can further clarify the steps needed to downgrade to Oreo. I have the 96OU unlocked US version and I upgraded using the modded Odin method for US Snapdragon versions in the Guides section. I do not like the carrier bloat that was added to my phone and would like to revert back to 8.1. I went to SamMobile and looked up my firmware which I believe is N96OU1UEU1ARL1, my actual model is SMN96OU1ZKFX. I have downloaded Odin3 v3.13.1. I originally used Odin3 v3.13.1 3B patchedD to upgrade. Do I run Odin (non-patched) then input the BL, AP, CP and CSC files from the extracted 1ARL1 file and select Auto reboot and F.Reset Time only, not re-partition? Can I use the patched version of Odin if I want?

I have been looking for a step by step tutorial for this but just can't find one.
