What to do with a V2 950U1 - Root or Update? - Samsung Galaxy S8 Questions and Answers

Thanks for so much amazing work. I have a Snapdragon 950U1 that still has V2 Bootloader and Nougat/7. From as much searching and reading as I can find here, it looks like the current choices for updating are:
1 - Root and be stuck at Nougat with 80% battery charging
2 - Update to Oreo or Pie, and permanently lose the option for root
Do I have this right? There's no way to get to Oreo and keep root?
If so, which would you recommend? Is Oreo/Pie worth it?

You can update to Oreo or pie and still have safestrap TWRP with Jrkruise mods.

Nougat finally available - Upgrade or not? Downgrade possible?

We finally received the nougat update for S7 Edge in Denmark (this means Exynos version, SM-G935F). But should I upgrade or not? I like my current version, I heard battery time is worse on nougat and so on?
Also, would it be possible for me to try nougat out and then downgrade to marshmallow if needed?
downgrade should be possible but only with custom ROM i guess Battery was good at start 7-8 hours but now I'am back to 5-6 h sot with my normal usage, and started to get some google play stops... Will try to do a factory reset because I see a lot of junk from MM like people edge, that should be removed with Nougat?
You can flash any stock rom with Odin and thus you can downgrade to Marshmallow if you like.
The battery usage is much improved in Nougat.

Which OS is best to use for Rooting G930V Galaxy S7?

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

Oreo Root?

Hey there devs and V20 users alike.
As if there wasn't already hesitation enough to root this headache of a phone, and just when I was about ready to take the dive, I received the Oreo OTA update about three weeks ago.
Since updating, I've been enjoying the phone thoroughly.
If I'm going to be honest, this is the first phone I've owned (out of MANY since the Galaxy Captivate S days) that I have been satisfied using without root. It's an absolute multimedia powerhouse. However, little things like the inability to utilize ad blockers, tweak kernels, access root storage, etc. Does bother me now and then, although infrequently.
I'm looking through the forum here, and I'm beginning to think that due to LG's unbelievably long release of oereo, and the difficulty of root, devs have long left this device in the dust.
Unless I'm missing something, is there any rooted Oreo ROM available ATM? I absolutely will not revert to 7.1 again.
Thanks in advance!

I can confirm the ls997 has oreo. and i've seen a few other people talking about their oreo updates here on XDA on different models.. Idk how many models there are of the v20 though..... Still waiting for ls997 root I'd love to OC this phone for even better performance Or at least manage its cpu to avoid overheating 24/7

root please
please dev, find a way to root my LG V20 F800S Korean version, Oreo. :crying:
In order to get root with Oreo on any model besides the H918, a custom kernel will be needed -- and I don't mean just compiling up the sources from LG.
I am going to try and migrate from my H910 over to one of my H918s .. but that is going to take a bit. Then I will have a phone that can use the eng. bootloader, and can actually start to work on it.

Hey Brian, glad to see you still around these parts lol
Edit
I thought the key to root on oreo with eng bootloader was the 996 oreo release or has that changed?
Sent from my LG-H910 using XDA Labs
Yea, I am definitely still around -- just nothing I can do right now.
I am pretty sure I can get it working with a modified kernel, but I need to be able to see logs -- so that means I need my H910

Recently they have found out that to get eng aboot to work with oreo firmware, it was just a simple zip making modifying 2 files.
1. stock aboot changed to common dirtysanta eng aboot
2. stock v20 variant oreo boot changed to magisk patched stock oreo v20 variant boot
We have to keep the recovery as stock recovery so letting the previous twrp get flashed over.
The key is letting the oreo firmware boot up first time with stock recovery and then data will work like normal
Then we boot it up first time and it will get to system and then do quick setup and then go into fastboot (thanks to the eng aboot intact) to push the twrp recovery back to working order again.
So it was just simply doing that instead of using patchd lg up to partition dl to ignore the 3 things : aboot, boot, recovery.
That means eng aboot is still good to be able to use on oreo for all dirtysanta v20s .
I am personally running h910 oreo root with very early build of mk2000 beta 2 oreo kernel. My phone gets full lte data like normal. The battery drain is much improved from nougat while still having the same kind of performance I was used to on rooted nougat.
Asked this on other threads but no answers yet, let me see if I get my answers here
I have a f800l lg v20 not Rooted
Android 7.0
Updated security patch 1st september 2016
Kernel 3.18.31
Build no Nrd90m
Software version F800L 10g
My question is that can I update my Android to Oreo 8.0 which is available via Software update and then gain root access? If no, what is the last update limit for me to not lose rooting possibility. Or is it possible to downgrade to a previous update state after updating it to either Oreo 8.0 or other updated security patch levels? What would you suggest? I've heard Oreo is good with little battery drainage percentage as compared to Nougat which is my primary interest. I don't want to make a move to lose my rooting ability. Are there any other means available to upgrade to oreo without using lg software update in order to achieve both Oreo and root? And if it is not possible to achieve both Oreo and root are there any custom roms or kernels available with good battery drainage percentage? What would suit me the best. Sorry in advance for asking so many questions and not knowing if these questions have already been discussed and answered.
Thank you
Your phone is still ARB 0, so you can do whatever you want.
As for rooting Oreo, now that I know that it expects stock recovery on first boot, I will be posting zips for every model that has a KDZ.
You will need to root your phone first. Since you are on September 2016 patch, use DirtySanta.

by the way, no point in making the zip for h915 oreo.
I have tried with the same new method zip that was made with the 2 modified files + stock recovery.
The h915 modem just doesn't want to work with eng aboot whatsoever just like how it was on h915 nougat rooted.
please post oreo zip file for F800L, i can't wait to have oreo rooted on my F800L

Perhaps this is something that can be circumvented in the kernel, like runningnak3d was talking about earlier, and like emdroidle did for H990.
I don't know how it works, but I could try enabling the same fix that's used for h990, for h915 oreo.
thank you runningnak3d
Ok I'll llet you know once I root my F800 L
Update: I managed to flash twrp via DirtySanta method. I can get into recovery twrp and use it but i haven't flashed SuperSu yet. I can't get comfort view working and the battery is draining relatively fast, So by flashing super su will I get Comfort view and old battery drainage rate back or do I have to do something else? Shall I flash supersu? I get a red triangle mark every time I restart my phone which takes longer than it used to in order to boot, which means I have Bootloader unlocked, can unlocking bootloader ignite problems like long booting duration, inability to use comfort view and fast battery drainage? What do you suggest I do? flash supersu? or relock the boot loader without getting Supersu? Will doing so even fix these problems becasue I planned on rooting to get better battery drainage percentage, instead I get more battery drainage, please help @[runningnak3d]
Hello!
I have a rooted LG V20 H990DS running nougat. Can I upgrade to Oreo without loosing root?
If yes, could you please tell me what is the best way to do so?
Phone: LG V20 H990DS

ROM: stock
Build Number: NRD90M

Downgrade from Oreo stock(8.1) to Nougat(7.0)

Hello,
1.Can we downgrade to 7.0 from 8.1? If yes,how?
2.Problems which may arise during downgrade?
3.If no why?
I'am fedup with the performance of 8.1,bootloops sometimes, network problems,and majorly battery backup and low volume issue.
#TIA

Did you installed the twrp version of an Oreo rom or which rom do you have. Did you have an unlocked bootloader? How did you update to oreo?
Upgraded to 8.1 (stock)through adb,i have bootloader unlocked and also have twrp.(no custom rom installed)

You cannot downgrade the bootloader if you flash the stock nougat rom by fastboot, otherwise it's hard bricked.
But I don't know if stock nougat rom will work with stock oreo bootloader @echo92, you know it maybe?

If stock Oreo is downgraded to Nougat, the bootloader may work with either firmware, I don't know for certain. However, OTA updates must be avoided if there's been a downgrade to Nougat or earlier (unless you're using the Oreo OTA); attempts to use old OTA updates on downgraded firmware is a great way to hard brick (and currently without recourse - we do not currently have a working Oreo blankflash).
However, if you downgrade your firmware, I am concerned you may lose SIM access/IMEI, given your baseband is on .77R (Oreo), whereas downgrading to Nougat would result in a baseband of .62.02R due to changes between the 2 basebands. You may have to consult this thread if you do lose your SIM/IMEI https://forum.xda-developers.com/moto-g4-plus/how-to/guide-moto-g4-plus-imei0-issue-t3859068
@anhoxhrs Have you considered replacing your battery, or at least ruled out battery issues like a failing battery? I'm just wondering if the bootloops and poor battery life may be due to the battery. Also, when you updated to Oreo, did you clean flash or factory reset your device?
The SOT has reduced by 30%,and most of the battery is consumed by mobile standby(weird).Its a clean flash. being my primary phone, 8.1 is troublesome.Yeah the battery was pretty good before the update.Chargeing time also has increased.for eg- 95 to 100 about 1/2 hr to 45 mins.

Flashing S8 (Exynos) From official PIE back to Nougat?

Hello everyone. Long time since i post.
I have serious problem. For some reason im not satisfied with a video performance and batterylife on Pie, and i wanna move back to Nougat (not Oreo). Yet Odin seems dosent alow me to do that. Please i wanna know if its possible, wich i presume it is, and what version of Odin should i use ? I do have downloaded 5 files official rom wich i already flashed last year from Oreo to Nougat, but i have problem flashing it from PIE to Nougat. What version of Odin do i need and what setting?

I have bootloader version 4 right now . Is it possible to use Oreo Rom with the same version 4 of bootloader and then i can flash from that too bootloader 1 oreo, and then to bootloader 1 Nougat? ? ?

You can not downgrade bootloader versions. So if your on pie with version 4 bootloader the lowest you can go is the earliest version of Oreo with bootloader version 4. Anything with 3,2 or 1 bootloader can't be flashed.
My god. So there is no Odin way or any other way to bypass bootloader restriction?

As far as I know no you can't downgrade bootloader versions.
Thanks for the reply. I just flashed the earliest Oreo firmware with bootloader binary 4 wich is actually last big change in stable releases of Oreo. NExt 3 releases were only security updates. I cant get lower then that since two more Oreo firmwares before that had BL number 3 and 2 - Nougat starts with 1 unfortunately. I really hoped maybe guys on XDa figured this thing out too downgrade to lower BL numbers, but i guess its not possible. .If i knew that before, i would never upgrade this shi..t to PIe. Hopefully Oreo will do fine now.
