To more experienced users,
I accidentally updated to G950U1UEU2AQK2 on the Snapdragon S8. Is there a way to revert to a previous version, so that the phone can be preserved for rooting?
It upgraded the bootloader. You're stuck. Root sucks now anyway
That sucks. At least I can use Samsung Pass. Thanks.
Stay tuned. The U2 n8 has been rooted so there's no reason to believe the s8 can't be too. If you are interested in trying let me know as I will eventually need a tester who is already on u2

So Nougat has been released for AT&T Users. I realize that Root for Nougat has not been achieved yet, but I want to get the ball rolling and start a discussion on the topic.
I'm assuming the engineering kernel root won't work on nougat, so we are once again without root. Has any development begun on root? I know there is pretty much no chance unlocking the bootloaders, but how long do you think it will be before we can get root? A month? maybe two? Do we know who is working on it?

It's doubtful that anyone is working on root. The engineering kernel was a lucky break for us on MM, but for Nougat we most likely won't see root unless someone unlocks the bootloader. Google has been increasing the security of Android with each update, so exploits are getting harder to find. Even if we do get the su binary in place, dm-verity will stop us from booting, and disabling dm-verity seems to require a kernel modification which the locked bootloader doesn't allow. I'm sure people are interested in unlocking the bootloader of our phone, but considering the history of Samsung devices and bootloaders, that chance doesn't look great. Maybe somebody ought to start searching for a new engineering kernel... it'd be a better leak than some blurry device pictures
Or if you got your hand on the international version, it seem that the international version is still rootable.
I really new to the Samsung dev scene so please forgive any ignorance.
Is this what you're looking for? It seems to claim root on the G930A on Nougat.

Don't use it if your chipset is not Snapdragon.
THIS IS NOT FOR THE EXYNOS VERSION OF THE S7! <- this was the big fat warning for anybody not reading it. My phone is currently the Exynos version, so I won't be able to root it.
I would like to downgrade my galaxy s8 (G950U) sprint version from Oreo 8.0 back to Nougat 7.0 but I’ve been having a hard time figuring out if it’s possible.
Looking around I’ve seen people saying that’s it’s not possible due to the bootloader which doesn’t allow you to go down from v2 back to v1.
It’s also my understanding that the fifth number from the right is the bootloader version, in this case I have version two (G950USQU2CRC5). Now, looking at the Nougat releases for the phone, the last three that were released before Oreo show that they have the version two bootloader (G950USQS2BRB1, G950USQS2BQL1, G950USQU2BQK5).
So, would it be possible to downgrade if I used one of these three versions or are there other things preventing this that don’t involve the bootloader?
Thanks.
Yes. As long as the bootloader version of the package and the bootloader version on your phone are the same, you're fine.
Also, don't flash a bootloader 3 package unless you want to completely ditch Nougat or don't want root for a long time.

did you ever get the chance to downgrade? could you please let me know how you did it? please include links to the files that work for you. thanks!
I am getting Galaxy S7.
So it will be totally new phone. This means that I intend to factory reset and no worries about data loss, new phone. This should make the question easier to answer.
I considered:
Keeping Marshmallow
Updating to Nougat
Updating to new Oreo which is just released to S7
Requirements:
Maximum compatibility with permanent root with no issues
Maximum compatibility with xposed
Maximum compatibility with various xposed modules
Ability to have BLACK everything I want absolutely no white menus anywhere.
I am coming from Kitkat. If I had my way I would keep KitKat, unfortunately KitKat 4.4.2 is not available for S7.
One only real benefit I see besides super slowing down my device on the new versions, is that Nougat and up I believe has a blue light filter integrated? It would be super cool because this is an important feature. Currently I use Twilight blue light overlay, but if I could have a native filter (like f.lux for PC) it would hugely improve my user experience.
Maybe I will like newer features, but maybe not. I usually DISABLE tons of stuff including:
Disable fingerprint
Disable updates
Disable face recognize
etc, I don't want any of that invasive junk.
I also don't use Samsung Pay or any other junk.
I like maximum control over my device and I hate white and have to have all menus black. I did learn some newer versions of android OS actually have theming engines included where I can turn everything black, that will be very great for me. White menus physically hurt my eyes especially at night. It's painful to me and causes red eyes. So I must have all black menus.
I don't want any problems especially not audio or gps etc problems and I never want to enable fine location.
So I wondered if you know which is the best OS to use to meet my requirements with best root and xposed compatibility and no problems. Marshmallow, Nougat, or Oreo and what version?
Additionally, I am also open to any recommended custom ROM, if you have any suggestion.
In further reading of threads I am getting worried. About to cancel my order and get refunded and give up on getting an S7 and just keeping my S5.
The reason I'm getting worried is because I am reading that US versions with Snapdragon processor G930V has a locked bootloader. I am unclear if I can root or not.
Advice would be helpful as I only just ordered and I am about to click cancel order.

From what I have read, you can root a G930V on Marshmallow and Nougat but not on the new Oreo build.
This guide is for Marshmallow:
https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039
And I believe this one is for Nougat:
https://forum.xda-developers.com/verizon-galaxy-s7/how-to/how-rooted-s7-nougatand-fixed-lag-t3576393
But no TWRP or typical custom recoveries. Only flashfire and modified stock ROMs. I think I read that Xposed worked on Marshmallow but not Nougat. Not certain on that though.

Well my S5 does have a custom recovery but is on stock rom, got full root when I downgraded to KitKat.
Thanks for letting me know it will probably be the same procedure. I did order it now. Going to try it. Hopefully, it works with full root,
Which OS+root is better, rooted Nougat or rooted Marshmallow (considering potential bugs)?
I think Nougat has a blue light filter built-in, is that right?
It may be a matter of opinion but I am open to hearing your opinions.
I received the phone today. It has this OS version G930VVRS4BRA1 which is 7.0 android I received the phone today. It has this OS version G930VVRS4BRA1
I don't know if I should change the OS or update OS or what or do for sure to be rooted
Right now I am on AT&T firmware CTA2 which is the v2 bootloader. I know if I take the OTA (I have it frozen so it doesn't auto update) to the March security patch it will update my bootloader to v3 and block my ability to revert back to Android 9. I am asking is anyone else in the same boat here and if so what did you? Keep v2 or jump to v3?
Anyone? Guess I am alone here on this one.
I upgraded to 10 before rooting mine, luckily the Binary code was still v3 aka build number G975FXXS"3"ASJG, so reverted to pie and rooted it.
Reason,as samsung are making it harder to root and i wasn't risking upgrading it.
Also no reason too, as custom roms will be made which will be 10, so best of both worlds

So what I am getting here is that you were on v3 bootloader and went back to Pie?
Yes, Look at the binary code, you will see number 3 in my build number.
there is a few more updates in pie, and also i think the first two in 10 that have binary code 3 in build number.
As i did update to 10 BUT only to the last update which contained the number 3 as i show in build number.
Thererfore i was able to revert back.
If i went further to binary code 4, then i'd be screwed
the last v3 you can use which is on android 10 and you can revert back if you wish is:-
2020-01-06 10 G975FXXS3BSL4 G975FOXM3BSKO
the next android 10 update v4 is:- 2020-02-12 10 G975FXXU4BTA8 G975FOXM4BTB1 (Do not update this, if you want to revert back to pie)
these are updates for my BTU G975f

Hey sorry for the real late reply, I just now dug up this thread. I noticed you have G975F phone. Is it rooted? I have a G975U phone. Does this matter? If I update to bootloader v3 (which is the bootloader my carrier is on), I can go back to Pie as long as I don't update to bootloader v4?
Reports in the forum here are saying once you've updated to a newer bootloader version you can't go back for the G975U version of the phone.

I did have the G975f which i did root successfully, sold it on and replaced it with the A71. which is much cheaper, a cracking phone, and has snapdragon chip which are much faster than exynos.
Midrange phones are now coming up to the main flagship phones, and cameras are excellent on it, and its also rooted.
Anyhow.........
Anyway if your s10 has the Exynos chip, you can root, if it has Snapdragon, as far as i know its not possible, you'd need to search.
As i mentioned in post, if the binary code aka 3 remains and it does in the early 10 release, then you can of course go back to pie, as i did.
If you upgrade to binary code 4 aka BL 4, you can not downgrade back to v3.
I'm not sure if it is still rootable at v4, you'd have to check, as like i say, i don't have mine anymore and never got to that stage to investigate.
Hope that helps you bud

So v3 can go back to v2 bootloader? I have a snapdragon G975U phone running AT&T firmware so I can't root it. I just don't wanna brick my phone if I unfreeze the update and update to v3 then wanna go back to v2 bootloader later.
My friends Samsung Galaxy S7 SM-G930A sounds worse on 8.0 than it did on 7.0, he seems to think so we need to downgrade to 7.0 again. Is that possible?
Thanks

afaik that's only possible when they use the same bootloader.
That means if the bootloader was changed while upgrading to 8 it may not be possible.
While using Odin it will tell you if flashing will work or not.
I would download both stocks and compare the BL... files if comparison is not answered somewhere in XDA.
It downgraded without an issue & upgraded again without an issue since my friend cannot make up his mind if he thinks 7.0 is worse or better than 8.0. Anyway it all worked out.
