I have a SM-N960U1

And i downloaded smart switch and it says my version of software can be reversed - But when i push the downgrade option it just sits there in perpetuity - is there a process for reverting back?
[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
Can someone please tell me what version of Odin i need and how can i get back to the previous version of One UI that was working with ACR - When new version loaded - ACR stopped working, im not a phone geek perse - but im generally pretty tech savy - but the sheer volume of reading over the last week, along with asking questions to no avail has indeed been a bit overwhelming as everything is so specific to certain things - I bought the Unlocked version from Best Buy in US - Phone is SM-N960U1 - 512gb - thank you in advance for anyone willing to lend a hand.
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
HI i posted this link few post ago https://www.sammobile.com/firmwares/galaxy-note9/SM-N960F/ATO/ that’s fine ATO for you! Also I’m from the UK i was on that gay pie one ui! Now I’m back on Oreo 8.1 happy days..

My Samsung Galaxy Note 9 is dual sim phone! I purchased it direct from Samsung uk! So flashing UK firmware would not be an issue in the (old days) But i have heard flashing different regions firmware’s messes up the oem lock.. So it’s best you flash the original firmware and not some other region firmware just to stay safe!
[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
Nope - Didn't miss it at all - But i have asked multiple times in multiple threads here - and although i would say on average i try to help others - I feel there is a slight different feeling here at XDA - I understand the issue on many levels - However - what i don't understand is how in the hell do i revert back to where i started, which - btw - is exactly all i want to do - I would consider rooting - but the Note 10 Note 11 upgrade with 5g is to big a gap to eat a 1500 crow pie. Please tell me how i can get back to where i started - thanks in advance ..
[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
Unlocked version from Best Buy in US - Phone is SM-N960U1 - 512gb - thank you in advance for anyone willing to lend a hand. Just want to get back to where i started and One UI on beta was working perfect with ACR..
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
Your not making sense ? quote " Just want to get back to where i started and One UI on beta was working perfect with ACR" So are you looking to stick to ONE UI PIE 9 ? Or are you looking to downgrade to Oreo 8.1 ? Witch is it ?
[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
Well, I maybe I am not relaying the information properly. Is the One UI os the reason that the ACR stopped working? Maybe I am mistaken in that it was working prior to the ONE UI update. How can I check that, or how can I see when I went to the ONE UI BETA? I just checked some of my ACR conversations and the last one that had both sides audible was in around mid December.

---------- Post added at 09:59 PM ---------- Previous post was at 09:50 PM ----------

Ok I just checked all the ACR messages and the last time that ACR was working is on December 11, I was on the ONE UI platform at that time, so I know it was working. Can anyone please help me to get back to the OS and ACR version on December 11, on the 14 the it was not working on both sides of the conversation, I can only hear myself speaking, not the other party.
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
Is ACR Call recording ? If yes it's been removed in the one ui pie 9 update! Only way to get it back is root that’s if you want to stick to PIE 9 or downgrade to Oreo 8.1! That's the only two options you have!
[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
How can I check when I went to the One UI BETA? I am fairly certain that it was working fine. But I don't know how to see when I switched to Beta

---------- Post added at 10:20 PM ---------- Previous post was at 10:05 PM ----------

Is there some log files that I can check?
[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
Does anyone know how to check the updates, or log files to determine when i upgraded to One UI Beta?

[Samsung Galaxy Note 9 Questions & Answers] TGAMO:
I can't exactly recall - but i believe that the One UI was updated twice after December 14th. Can anyone confirm how many times the Beta UI updated prior to the official rollout? - I really think that the ACR was working properly with the One UI prior to the security update. It would be greatly appreciated if anyone could help with this issue. Thanks in advance.

Downgrading to Oreo from PIE (Warranty)

Good Morning

Apologies if this has already been highlighted, or in the wrong forum.

My question is, I have a Samsung Galaxy NOTE 9 SM-N960F/DS Factory Unlocked. I was on Oreo has it was great, but kept on getting these notifications to update and when I did it updated to PIE, well didn't want that I thought it was just a patch or security update. Anyway I would like to downgrade back to OREO and like to know the following below.

1. Where can I get original firmware for SM-N960F/DS

2. Will this VOID the warranty if I flash the firmware

3. I don't want ANY custom ROM, or ROOT firmware that it will brick the phone and void.

I already have ODIN and also I have download a firmware from sam frew
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
SAMFIRM.EX For firmware or Sam mobile if you got 10+ hours spare to download firmware and i used Odin3_v3.13.1_3B_PatcheD to flash Oreo 8.1 and it does not void warranty!! Root and Roms void warranty and trip KNOX enjoy

---------- Post added at 04:09 PM ---------- Previous post was at 04:03 PM ----------

You are on the December security patch!! As i said before you only got 2 options, Root or Downgrade to get call recording! And I can see *#123# don’t work on your model Sorry cant be any more help. But if you want to downgrade all the info is in the first 20 post of this thread root just search XDA!

Is there any way to determine when I first downloaded the new ONE UI beta?
[Samsung Galaxy Note 9 Questions & Answers] tmac200913:
When you say do not add the Home_CSC, what do you mean by this exactly? In my Firmware package, I only have one CSC file (shown in Attachment). Are the files in my folder correct, and do I add that CSC file to the CSC slot in Odin, or am I missing a CSC file, or do I just leave the CSC slot in Odin blank? I am on AT&T US (SM-N960U), attempting to flash last Oreo 8.1 update (December) Thanks!
[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
HI that's fine you can put the CSC in the CSC slot and flash away! As you dont need to flash HOME_CSC i just flashed for the fun of it, i just wanted to see what happens, as you know i was stuck in an boot loop!

See flashing HOME_CSC is for keeping your data! For example apps, pics, settings, etc! But since we are downgrading it does not work flashing HOME_CSC! Also i'm on Exynos model 'your fimrwares are slighty different to mine, i.e you dont have HOME_CSC..

You will be fine just put all firmwares in each slots and flash away!

[Samsung Galaxy Note 9 Questions & Answers] N1NJATH3ORY:
Dude use SAMFIRM.EXE it takes under 5 mins to download firmware and the beauty for SAMFIRM.EXE is you input your model number and it downloads the right firmware for your Note 9!!

So you don’t need to ask us, if it’s the right firmware for your smartphone. If you check the few 10 post of this thread there is a link to download SAMFIRM.EXE!!

Eff Sam mobile it sucks for download speeds!! SAMFIRM.EXE is the way to go!!

Update Successful

Good Morning ALL

After looking through the comments to downgrade and searching and help from you guys, I can confirm I done the following to work. I download SAMFIRM as requested but this only pulls the Samsung latest firmware which is not a problem. I did download that for later use and also to test it, I also went to samfrew to search for the model and downloaded December 2018 Stock firmware OREO 2018. After downloaded I used ODIN to import the details but I did not choose HOME_CSC for reasons. Anyway I flashed it successfully to Oreo and did not void the warranty or KNOW at all Everything it working fine now thanks for your help back to Oreo and I was running into all sorts of issues with PIE:good:
[Samsung Galaxy Note 9 Questions & Answers] high_voltage:
The update needs around 10 days before it massively speeds up/smooth out in the UI. Atleast for me it was like that after flashing the update.zip over my oreo. Right now I am again in the same process and it's still not that smooth/fast, after full wipe and the latest update clean install.
[Samsung Galaxy Note 9 Questions & Answers] dkaldenekker:
Hi Guys,

I read through the whole topic and I think I'd go for the downgrade too. Just before that, can you please help me with answering my questions?

1. I'm ok with pie, the only reason for downgrade is that pie doesn't come with the hidden network settings system app. (com.samsung.hiddennetworksetting) I need this app for band selection like lock to B40, B3, B1 etc (no system or technology change). This app is missing from pie and I couldn't install it either

2. I don't want to lose warranty and later OTA upgrade possibility. Can I srill keep both even if downgrading?

Thanks,

Dez

Region is SPR

You'll need to do a factory reset when downgrading or you'll get a bootloop.

Factory reset was already done. when I go to samfirm.exe and type in the model and region I get: the remote server returned for an error:(403) forbidden.

I currently have the first official Pie update for Canadian Snapdragon SM-N960W Note 9 with Carrier ESK which is Eastlink Canada. No need to list all the reasons why I wish to go back to Oreo, but will consider pie again when it is more refined & Further updated. My 2 questions are...

1. Can I use this firmware (photo 1) to downgrade to, I grabbed it off updato & it's the last/most current Oreo I believe. I mean will it work or does it depend on anything in particular?

2. Will this be fine considering the bootloader I have, and which version of odin/modded odin should I be using. I've rooted other phone models, & have used odin before, but don't want to brick this phone as I cannot afford another one of this model. If it's too risky I guess I'm stuck on pie. :( Any help here would be greatly appreciated!

[Samsung Galaxy Note 9 Questions & Answers] gn4life84:
Woke up to a forced Pie update...horrible

Lost my ability to minimize and play YouTube videos from the browser in the background while I multi task. Also lost the fast foward and rewind buttons on the player.

I use these features the most too. . Totally not an upgrade for me.
[Samsung Galaxy Note 9 Questions & Answers] Mr. Orange 645:
Yes that firmware will be fine. You're still on bootloader 1 so you can downgrade. There's no rooting involved. It won't trip Knox. Use patched ODIN. You will have to do a factory reset, so back up your data.

Just click auto and hit search. It will pull the most recent version of the firmware for your device.

Those features are still present on my build of Pie. Maybe check the app settings, clear cache/data, etc.
[Samsung Galaxy Note 9 Questions & Answers] gn4life84:
Thanks for reply....

So you can go to your stock web browser. Go to YouTube's normal website, desktop site version.... play a video in full screen mode....then have the option to minimize and adjust the size of the vid and move it anywhere on your screen at any size.... while you open and use other apps??
[Samsung Galaxy Note 9 Questions & Answers] Mr. Orange 645:
Oh I guess not. I use the YouTube app not their website. I misread your post.
[Samsung Galaxy Note 9 Questions & Answers] gn4life84:
I preferred the site because....

The app use to work to where you could move and adjust the size of the vid in the background. BUT it was limited. You couldn't move it to the corners of the screen and the size scaling options were fixed and limited.

When you did it from the website player you could adjust the screen to any size and put it anywhere on the screen. So no matter what app you were multi tasking with you could always position the vid to where it was not in the way or so that it was in the perfect position and size to still watch and do work. The whole point in having a smart phone.....Simple as dragging it with one finger to move anywhere. Or 2 finger diagonal stretch or contract to maximize or minimize size. Thia was not just for YouTube but most vids in general. Was an Awesome feature!!!!

Here is the kicker.....now with the update you can no longer even adjust the size of the vid in the background while multitasking with the Youtube APP. And it's too small to even watch efficiently. Still doesn't let you move it out of the way into the corners. Can you adjust the size on yours ?????????

Not to mention clicking on an X to close apps is no longer an option... you have to use and learn a swipe gesture. So backwards...

Also looks like less viewable screen while web browsing because the home menu bar doesn't stay translucent while on certain programs.

-Less function

-Less multi tasking

-More complicated non user friendly steps to do simple things

-Less viewable usable screen

Gee what an update.....

And that's only after about 15mins of daily use so far
