Downgrading and Rooting Samsung S9 SM-960U - Samsung Galaxy S9 Questions & Answers

Hello XDA
hello XDA I am Wondering if there any methods out there to downgrade and root Samsung SM-960U I was originally on Sm-G960W if that helps and I am currently on android 9.0 [and would like to downgrade back to 8.0 if that's possible if searched around and really haven't found anything to my exact phone model to do these things but don't wanna risk my phone since I already bricked it 1 time

Seems like a LOT of S9/S9+ users hate the taste of Pie and want to go back to the Cookie (Oreo); where I am curious is *why*. (As to why I am curious is because I'm at the opposite end - I'm an S7 Snapdragon owner that has no Pie as an option (unavailable for the platform) and I wonder where all the Haterade is coming from.)

G928A firmware downgrade?

I'd firstly like to state I am new to the forums, and give my thanks to brilliant people who give guys like me somewhere to turn. Now, my question is, is it possible to downgrade from MM PJ1 to OGG or OJ1 or lollipop in general. I've seen a similiar thread about a UAE version or somethung that said it was possible. I have successfully downgraded a Note 3 from lollipop to kitkat, which has locked bootloader too if I'm correct..?, but I would like to have any input before I do this as it is my main phone. Thanks!
yes it is possible.

So in theory, i could downgrade to Lollipop and use the kernal auto-root to possibly get rotot? I just got an HTC 10 so I'm really itching to mess around with that s6 Edge Plus. Lol.

Rooting Galaxy Note 8 wifi N5110 and updating to Nougat or Android 7.0?

Hello everyone. Please forgive me but I am a super newbie in regards to rooting and terminologies. I have a Galaxy Note 8 N5100, wifi version. It has the original firmware 4.4.2 and I would like to upgrade it to Nougat 7.0. My son is having trouble playing new games on it so I theorized that it could be due to its age. Before I buy a brand new tablet I figured I would try to see if updating the N5100 would help.
I have googled and saw this link and it seems fairly easy.

Is that the correct thing to go through the process? And to update to Nougat I saw this:
http://www.android-nougat.tech/2017/03/samsung-galaxy-note-8-0-wi-fi-5253.html
Or if there is a better/easier way I would appreciate it. Thanks.
Wish I could help. I'm just getting back into this tablet myself.I'm sure someone will show up with info.

Hi! I was planning to do exactly the same thing -- upgrade my trusty Samsung Galaxy Note 8.0 to Android Nougat -- and from scouring the XDA forums re this device, it seems to me that we have two popular options (based on the comments and thanks-ratings).
Here's the link to the more popular one, it's been renamed LineageOS 14.1 by the developer(s) but is based on Nougat 7.x:
https://forum.xda-developers.com/ga...m-unofficial-lineageos-14-1-gt-n51xx-t3533329
And if for some reason you don't like the name of that one (or for any other reason, just to have an alternative), there's another popular one called RR (short for Resurrection Remix OS). It is based on Nougat 7.1.1_r25 and nightlies of LineageOS 14.1:
https://forum.xda-developers.com/ga...t/rom-resurrection-remix-5-8-2-rel-1-t3571116
I'm about to upgrade to LineageOS now (wish me luck). The reason I'm choosing LineageOS is 'coz it seems to be more popular and is ported to more devices.
Hi I own the same device as you and I flashed the RR rom to my tablet it was really easy, you need to root your device first and then install TWRP (Team win recovery project) after that follow the instructions on the rom
do you lose touchwiz and spen?
Hi,
Do any custom roms offer touchwiz or spen?
Thx

If you are looking to use a more current rom with Marshmallow or Nougat, then yes you will lose touchwiz and probably most or all s-pen features. AOSP roms like Lineage and Resurrection Remix are based on stock android, but sometimes they're the only way to keep an old device current. Touchwiz roms are usually adapted from original firmware or ports from similar devices. Since this device stopped receiving updates at Kitkat, the most up-to-date touchwiz roms you'll find for the Galaxy Note 8.0 will be Kitkat.

Porting ROM without Root

Dear Experts,
I have a strange situation I am facing at work. I need Blackberry Work on my phone. My company doesn't allow rooted devices and it came up with a new rule that Work needs Android 6 or higher as per company policy going forward.
I have T mobile variant of Note 3 and the last stock rom was lollipop. I would need to somehow get an unrooted stock rom with android 6 or higher on note 3. Is that possible?
since samsung has not released Android6 for note3, Now it is only possible to get unrooted Custom rom for our device. However I think Blackberry Work will not work on unrooted Custom rom. Because Blackberry Work verify so many things before activation. ..

Downgrading from Oreo back to 7.0 Nougat

So, I currently have a samsung s7 active that I purchased used, unlocked but was using AT&T with the AT&T firmware on itat the time. I upgraded it to Oreo universal firmware
It's currnet running info is
Baseband: G891AUCS5CSB1
Android Version: 8.0.0
Samsung Experience version: 9.0
Android security patch level: February 1, 2019
How would I go about downgrading back to Nougat but the Universal firmware?
I'm quite new to the android system, and all the guides seem to have different steps to use and there seems to be a million firmwares for each version.
I was looking at the thread linked here, and there seems to be 3 of the same firmware that are all different somehow???
What would be the best, easiest, and quickest firmware to use and guide to follow? I want to go back to Nougat with the universal firmware and my phone to remain unlocked of course
any help is greatly appreciated. thanks!
the problem with this dam phone is the locked bootloader! snapdragon samsung sucks... PLUS it was exlusive to ATT
such a shame. a phone with an AMAZING camera even today and the BEST design for its time... only to be locked to AT&T, LOCKED snapdragon and really ****ty stock software super lame
because of this I'm not sure the thing can be downgraded
Hello, is that the case then? That the S7 Active can't be downgraded back to android v.7 Nougat ? I'm hoping that it can, as AT&T just forced the v.8 Oreo into my S7 this morning, and now I no longer have the very useful 'Usage Manager' app. =( I used it more than any other app, to enable/disable mobile data on the fly, and kill all running apps in background, etc etc.
Please let it be..... downgradable !=(

The first step to rooting a device is unlocking the bootloader to allow modified or custom images. Unfortunately, Samsung Snapdragon devices are generally NOT able to be unlocked.
See this guide. If the OEM Unlocking toggle does not appear, your device cannot be unlocked.
