Questions about root on Exynos - Samsung Galaxy S8+ Questions & Answers

Hi guys, I'm thinking about rooting my Exynos S8+ G955F but there's a few things I wanted to confirm first.
First of all I know rooting will break Knox so no Samsung Pay/Health/etc. That's fine, but will it affect Sidesync? I use this daily and don't want to lose it.
Secondly all the info I've read suggests that rooting will break OTAs which doesn't line up with what I know about Magisk. Is there no systemless root available, or is it because rooting breaks Knox and no Knox means no OTAs? If I can't do OTAs can I still sideload updates?
Finally, should I consider any custom roms? I don't really want to be flashing an update every other week and I don't want to lose Android Pay so I'd rather stay on stock unless there's a good custom rom I should try.

You will need to flash back stock recovery in order to get ota updates.
Why do you need to trip knox??
you can root the S5 without tripping Knox!!

Even with the latest os 5.0?
I used to have an s4 and back then no one has found out a way to root it without tripping Knox and I'm not going to flash any custom rom. I just want the xposed framework and lucky patcher

You can flash back to kitkat and then upgrade with flashfire to stock rooted lollipop.

Really, and how is that done. I have an S5 on AT&T running 5.0, phone was replaced through warranty for a newer version of the S5.
Towelroot didn't even work on my phone when it was on 4.4.2 through 4.4.4
So if there is any that you know how to root my phone, please let me know because I've been looking for a working root since I obtained the phone.

Root 5.1.1 - Dont care about tripping KNOX

I'm on the newest OTA of 5.1.1, and I want to root and don't really care about KNOX anymore. I just want to do so without wiping my phone or losing any data; custom ROMs are out of the question.
PignPong and Chainfire don't work for 5.1.1, the non-KNOX tripping solution breaks vital features, so I'm wondering if there is another way.
If you want root and not worried about knox flash this http://forum.xda-developers.com/gal...d-development/kernel-stockmod-kernel-t3100395 kernel to gain root.
I'm afraid there is still no method that will meet your needs.
Does this break anything? All features intact, no need to reset the phone?

To Root or Not to Root

Hello Community!!
I have owned many androids over the years, and have recently got an S6, hoping to dive back into the game of rooting, modding and messing around until my phones works the way i want it to. There are MANY things that really Piss me off about my T-MObile variant of the S6, including the horrible battery life, bloatware, and lack of personality. I Really would love to root my device, but KNOX. OMG what is this?! If i Root, no Samsung pay? What other downsides are there to rooting? But recently, my phone installed "ANdroid Pay" SO I am thinking, I should just root, forget Samsung pay and just use Google pay or whatever they call it.
As you guys can tell from my sig, I have been very inactive on these forums. I am hoping someone can give me some advice here---
Thanks So much

There are pros and cons to root.
The first pro is limitless customizations and personalizations.
The first con is OTA updates get disabled.
Another pro is you are able to dramatically improve battery and overall performance using various apps.
Another con is your warranty will be void, assuming you tripped KNOX.
If you trip KNOX, Samsung Pay no longer works; if you have root (even without touching KNOX) Android Pay does not work.
I obtained root just to prove to myself it could be done.
Since then there have been dramatic improvements with speed and battery life.
Package Disabler Pro can freeze a lot of the bloatware without root: https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en
Hi,
It's a highly personal decision. I myself for the first time am holding on rooting - I was the one who made the most famous Xoom rooting tool and also S4 Linux Root Script, so that tells a lot. The thing is, meanwhile my device is satisfying my needs, and I'm really curious about Samsung Pay, as it has a way wider support than Android Pay and other systems.
The best thing about rooting in my opinion was the endless system customization - specially after Xposed was released. The way better data management I had, better system control and some exclusive apps that require root or works better with root. If you are really pissed about Samsung TouchWiz apps and system "features", rooting would be a nice idea. Just keep in mind that after rooting Knox will be tripped and there's no turning back with Knox. Depending on your country, Knox trip also means warranty void, because once rooted you can unroot and make it looks like nothing happened.
Just adding what was already said, but Android Pay doesn't work with root.
All the best,
~Lord

Rooting doesn't allways mean tripped knox. I have my G920F rooted and knox intact. This can be done even after updrade to 5.1.1 stok firmware.
An android phone for me is worthless without root permissions. I need it for:
adaway adds
iptables (firewall)
better battery life (debloat)
titanium backup

I was only aware of root that can be applied before upgrade to 5.1.1.
Can you advise how you applied root after 5.1.1? Thanks.

Just install de 5.0.2 engineering bootloader via ODIN. Then instal TRWP via ODIN.
After this two steps you can flash whatever you want via TRWP.
Edit: with the 5.0.2 bootloader you will loose fingerprint scanner, the rest works great, at least with the custom rom I am using.

Keep in mind this engineering bootloader does not work with all variants. For example there is no Eng Bootloader for the Canadian phones.
Thank you both. I have the international SM-G920F (technically it's the dual Sim version, SM-G920FD, (from United Arab Emirates)).
So, to confirm, would the eng boot loader still work on my device variant, and allow root without tripping KNOX?

I have the single sim version of the G920F, so I don't know if it will work with the dual sim.
I don't think that it will strip you knox...
... and I think that if your phone doesn't work with this bootloader, you can just flash the correct one and make it work again.
But these are just guesses... you decide if you want to take the risk.
Good luck.

Thanks. I did some additional research, thanks to your advice about eng boot loader, and seems like it will work ☺

Hi,
I wouldn't risk that "you can just flash the correct one and make it work again". If you know how a bootloader work, if it gets broken there is no way to get to Download Mode and flash a new firmware/bootloader.
For information sake, a bootloader is a piece of software that is the first thing loaded when you boot your device, it comes before anything, be it kernel, be it recovery or anything else, that means, if you have a broken bootloader, the moment you try to boot your device up, it will try loading BL and it will fail, so it will shut down back again. I've had a broken BL once before on S4, the only way to recover was a direct flash of software in system chip using a tool called JTAG.
So, all I can say to users who still didn't get it: beware with this. It seems that many people are getting successful results, but it's an extremely risk procedure, make sure you read every single instruction and follow it, the possibility of a hard brick is high.
Even still, it's a great find, thanks for sharing with me, I didn't know of this until early today .
All the best,
~Lord
I wonder whether Samsung pay will work again after reflash stock rom after root? Is it like knox, once rooted you will never have it no mater what you do including going back to pure stock?

Did you mean, once rooted we can unroot and install the stock firmware and hence tripped Knox will be restored as well?
Or the unrooting will only help to restore the stock but the knox will continue to remain tripped. I would like to know this as I am considering purchasing S6. The last samsung phone I owned was S2 and used that for 3 full years with out any problems.
Thanks.

Once Knox is tripped its tripped but, yes you can flash original firmware and as long as you factory reset it, it will be unrooted and ready for official updates.

Thanks. But can you be a bit more specific of if the unrooting, flashing stock, and factory resting will finally untrip the tripped Knox as well? My question in the event I need to take this back to a service center to claim warranty for whatever reason, is there any way for them to know that I have voided warranty if I unroot, flash back the stock and factory reset?

Once tripped there is no going back. Voided warranty depends on laws of your country and your retailers policy.

YOU CAN NOT UNTRIP KNOX, you can reflash your firmware from Sammobile, http://www.sammobile.com/firmwares/database/SM-G920F/
use odin and then after you flash, go into recovery or use system settings and conduct a factory reset. It will say Official in the status but, since they will reflash your rom anyways, they will see the knox trip.
It depends on where you purschased your device whether or not they will warranty it with Knox tripped.
Honestly, anyone who roots should understand this information before hand. You should always know how to return to stock unroot.

After rooting my 5.1.1 without tripping Knox, with the 5.0.2 engineering bootloader (as as described a few posts ago) I have flashed a stok rom with odin and then everything went back as it was before the rooting procedure.
1. I was on stok oficial rom with oficial bootloader.
2. I lost root.
3. Knox was still intact: 0.
4. Fingerprint scanner and MyKnox worked again.
So: after upgrade to 5.1.1, rooting with the 5.0.2 engineering bootloader seems to be safe and also easy to bo back to stock... at least for my model (G920F)

Newb Question re: Rooting

Hi All,
Apologies for the dumb question.
Just got a brand new unlocked Exynos s7 edge. My main concern is bloatware.
Is there any way to root the device to clear out bloatware without tripping Knox counter?
After rooting, do I need to install a custom ROM or can i leave the stock image. If i left it as is (only rooted) would i still get updates as per normal?
thank you

Root disadvantages/drawbacks

Hi all,
I'm considering rooting my g955FD (s8 plus duo), can you list disadvantages of doing it?
I heard you lose private folder with root, is it true?
What are other issues, apart losing OTAs?
Thx

Once any custom binary is flashed, the knox couner goes 0x1. Therefore a Knox container cannot be made.
Once it's tripped, the following functions are lost forever: Samsung Pay, Secure Folder, and whatever else depends on Knox.
You still can probably use Android Pay, and be careful with how you store information on your device, but yes, there are features lost if you do it. If you use them, or plan to use them, don't root/flash.
If you're fine with the tradeoff, read carefully the threads (follow ALL steps when flashing TWRP, including the zip that disables dm-verity!!!), and start flashing.
I think you should not root the phone
This involves a lot of risk
