Will Root format my Phone? - Samsung Galaxy S8 Questions and Answers

Samsung SM-G955U w/ Android 8.0. Really annoyed by all the bloatware that's on this. Can I root this phone without a format? I found a bunch of different guides but not sure which one is best for me.
What do you think?
Thanks!

No format is a must. Look in the s8 plus threads for the latest method

Will it require downgrading my version of Android?

Yes only 7.0 is rootable. Think of it more as a side grade. Downgrade is not possible

Thanks for the quick reply. Can you provide me a link to that thread? I couldn't find it when I previously looked.

[Q] Is the newest firmware rootable?

I'm about due for upgrades on my account and trying to decide which phone to buy for my wife. Deciding between the Galaxy S5, HTC One M8, and LG G3. I prefer the S5 because my wife is more familiar with Samsung phones, but I need to know if it's still rootable or if Verizon has managed to completely lock this thing down.
I apologize for asking a question that's probably answered multiple places, but despite my best searching, I'm unable to determine the newest firmware version available for this phone, nor if there is any root method available for it that doesn't require an unlocked bootloader (presumably impossible with a "new" phone now).
I'd greatly appreciate a quick answer or a nudge in the right direction to look for this information.

You have to downgrade to NGC to root. Then you can upgrade and keep root.
OD5 is the latest firmware. See down in the notes to see how to root.

Thanks for the info. That's encouraging. I found that thread earlier but it says that method is only possible if you are already rooted...?

[Extremely Confused] Rooting the T-Mobile Galaxy S5 and flashing Cyanogenmod 12.1

Hi I recently got a T-Mobile Galaxy S5 and I despise Touchwiz. It looks ugly and more importantly it makes my phone extremely sluggish (it feels like my Moto G when it would run out of RAM). I want to root and put a ROM that's as near stock as possible (I'm assuming CM12.1 is the best option for that) but I haven't rooted since the Galaxy S2 so all the information I'm reading is super overwhelming. All these stickied posts seem rather outdated coming from like 2014 and such. I'm on 5.1.1 and I honestly just want as lagfree of an experience as possible. Can someone here please help me acheive this? I've been researching for 2 weeks now and I'm horribly confused. I keep reading about custom kernels and all that but all I want is my phone to not suck.
You'll get more answers in the correct forum
http://forum.xda-developers.com/galaxy-s5/help
Have you tried a different Launcher first though? TouchWiz Launcher is terrible, Nova Launcher is what a lot of people use, myself too, super fast, smooth with 100x more customisation options

I'm not rooted. I'm confused because when I try to figure out how to root and flash my phone all I see is a bunch of different guides and I'm not sure which is the one I should do.
Not sure if the T-Mobile bootloader is locked, I know the Verizon one is, and another US carrier, if it is locked, it's a PITA
If it's not, flash CF Auto Root for the G900F with ODIN

T-Mobile S5 doesn't come with a locked bootloader which is good. I have the G900T would that work?

If you're sure it's not bootloader locked, just flash this with ODIN

How do I flash something with Odin? And will this work on 5.1.1?
Best do some reading before messing if you don't know how to use ODIN
And no, I don't believe it works with 5.1.1, there is a thread about rooting 5.1.1

Was the same for me when I got mine, I spent 2-3 weeks reading every single thread I could before I decided I knew enough to root and be confident I wasn't going to brick it
And that was after I was already well experienced with Android, just a different device
Don't try taking shortcuts is my advice, asking for help and guides is one thing, but reading absolutely everything you can first is the only sure way to not kill your phone

Sorry for the off topic question but can you or anyone else please link me to your root method (if in fact we can root with Nougat) I cant seem to find a definite answer. Im unlocked G935U, my carrier is AT&T. Currently on G935UUEU4BQF3

This is the only one that I know of that will root the Nougat version of the S7 Edge. It is a very long thread, and there is a lot of information that can help. I know it works as I tried it on my G935U at one time.

Excellent! I wanted some confirmation from someone with the same phone (unlocked AT&T on N.)
Have you remained rooted since? I'm hearing mixed reports about performance and things stop working.) My primary concern though is our locked bootloaders. If we make changes that cause problems can we undo it? Like flashing the stock firmware? Thanks

Yes, I have remained rooted, but I ended up going back to stock G935A and then rooting again with that procedure. Personally, I was not getting the performance I was used to with the G935U as I was with the G935A with the root procedure.
Yes, there are some things that do not work with these eng.imgs that are being used to root the phones. There is NO Xposed for this one, Samsung Pay does not work, but I have been using Android Pay and it works just fine. As for the Bootloader, it is still LOCKED. There has not been any Unlocked bootloaders for the G935 or G930 so far and I don't think we will see it anytime soon.
As for Undoing, yes. There is a very simple way to go back to stock with Odin. In fact, about once a month, I return to stock just so I can get the latest security patch and then re-root my phone back to this way. I know it is somewhat of a pain, but with Titanium Back up I can get my phone back to running normally in a couple of hours.
Hope this helps...
It's not quite as fast, but if you are backing up and restoring to the same device, you can just use ADB. I still have a TiBu license, and use it on my Tab S2, but I have largely adapted to not having root on my S7 by taking advantage of basic ADB features.

Great info. Thanks!
One followup--when you say Xposed doesn't work, do you mean you tried the newest Nougat version that just got released? Or it never worked, not even on M?

What I meant was Xposed doesn't work on the current version of root using the eng.img. I have not tried using the NEW Xposed that is in THIS thread. I have looked at it but have not had a chance to run the zipped file and installing it. I know it works with MM as I had it working GREAT with MM and the eng.img with that version. I love Xposed and wish that was available for Nougat and N's root. I am keeping my fingers crossed that it will be fully implemented soon.

I tried this 4 times and failed. The problem is it just keeps rebooting (about every 45 to 60 seconds) after I flash the eng boot img. Im never able to run adb commands. If I start from a clean slate I can't even make it past the setup screens to enable debugging.
I'm reaching out to you because you succeeded with the same model SM-G935U
So I'm just seeing if you have any insights. My phone should be the same as yours. Only difference is mine came with 7.0 preinstalled. Maybe an earlier firmware? But that doesn't make sense because people are, to my understanding, using the eng boot with recent firmware.
I'll repost in the root thread if I need to but thought I'd see if you have anything to offer. Thanks

I seem to remember the constant rebooting on the U-Firmware also. I too kept trying and it finally took. I think I would take the OTA from the server and try to install the eng.img with Odin. When you do this, does Odin give you any errors? Or does it succeed at the installation?
It has been a few months since I rooted the U-Firmware so not for sure what fixed the rooting process. Sorry I couldn't be more help...

Thanks. No Odin works perfectly whether I flash eng boot or stock.
I looked at the root guide for Sprint and the process is a lot more involved. I believe he boots to recovery twice and wipes cache plus factory reset twice. He also stresses to get the root.bat run quickly to avoid bootloop.
Might be worth a shot but the process of running Odin, getting back to stock and restoring all my data winds up being close to a few hours so It'd be very helpful to find someone with the same issue as me who was able to resolve it.

How to root the samsung galaxy s8 Active?

How to root the samsung galaxy s8 Active?
Is there a guide for it?
And if anyone had tried to make this S8 Active have stereo sound, it would be very useful like other phone that has stereo, it sounds better.
There is no root for the ACTIVE and most likely never will be one the active 5 and 6 never got root.

Well, there's "[Root][G892A/U][V1/V2][SamFail][ROM]PartCyborgRom, Root for the Galaxy S8 Active", but I think the take away from that thread is that only the early firmwares were rootable.
EDIT: Specifically, see this post to perhaps get that rooted custom ROM working if you are on a v4 or v5 bootloader.

You could try a "package disabler" type application on the Google play store, never used one myself but it says it disables bloatware without root.
I know... not exactly what you asked for but somewhat useful.
Kind regards.
