I had long been using a rooted phone before I got the S5, but things seem a little different now. I held off on rooting the S5 because I wanted to be sure that I was going to keep it long term before I did. So yesterday I did some research on here and elsewhere and ended up rooting via towelroot and getting SuperSU installed without flashing. Now I just need to figure out a few things and was hoping to get some help understanding what comes next.
I've been reading about concerns over tripping "Knox" holding folks back from flashing custom recover and ROMs. I'm not a touchwiz fan but I can tolerate it. If there were no cost, I'd probably just install Xposed or something like that but is this Knox thing important? What am I giving up if I flash a custom recovery?
SuperSU "disabled" Knox when I started it. What functions of Knox are disabled? Can I flash recovery and roms without incident now that it is disabled?
Almost as soon as I got done rooting and installing SuperSU last night, I got a notification from samsung saying that "an update is required to access samsung services". Was that triggered by the rooting of the phone? Can I install that update without loosing root access?
Last question: Now that I have root, what do I need to do to keep it? Will it be rolled back by any OTA update, and if so, what must I do to prevent that?
Any help would be greatly appreciated.

You wouldn't have had to search or read very far in the forum to find answers to all of your questions. These get asked over and over, pretty much every day.
If you are contemplating a custom recovery, then read a thread about e.g. TWRP to learn about it's advantages. As just one of many advantages, it's the only way that you can make a proper, 100% backup.
Installing a custom recovery will increment Knox because Knox has not been removed from the bootloader. However most people don't obsess about the Knox flag. The only significant downside to the flag is that it might invalidate a minority of warranty claims.
Block e.g. rename or freeze the OTA updater to avoid losing root. An update will generally break it and there is no assurance that you will always be able to reroot. SuperSU Pro has a feature that attempts to restore root after an update.

Edited this original post here, it was 3:30am when I typed the original.. Anyway - anyone know if rooting can cause any type of instability on it's own? Without installing custom mods, roms, etc - does the act of rooting potentially cause things to not work as intended from the carrier? (my friend had an S3, rooted, and allshare stopped working - he was only rooted). I know there is some type of exploit involved in gaining root access, so that's why I ask. It's not a critique on rooting, I want to do it myself.

Anyone? I know it says "at your own risk", but i am curious - are there inherent known issues that can crop up just from rooting alone, maybe from just the method of gaining root through the system?

There may be a few things that don't function properly as a result from rooting. But it's 99.99999% of the time not an actual issue with the files on the phone. Nothing should be modified except for root access.
One of the ones for sure would be ota updates. I read someone else was having issues with one of the Samsung apps for streaming video to devices. These issues and others like them were caused by the system status being changed to custom and can be solved quite easily by setting the system status back to official with wanam xposed. With root and the status set to official your phone should preform exactly as stock in every way except you'll have root.
But be aware if you accept the ota while rooted you may lose root. Would have to re root or use supersu pro to maintain root during the ota.

Rooting will give you many benefits. Some of these include unauthorized apk installation, developer mode, custom firmware/modem improvements and fixes for some less functional stock features. This list could go on and on...
Most carriers frown upon customers rooting their devices for a few reasons; liability, damage control and profit above all.
When your device is rooted, custum, unofficial, and/or the Samsung KNOX binary counter has been tripped, Sprint/Samsung will consider your warranty void. Basically you will need to return the device to official stock and unrooted if you need to have your phone serviced.

Fully agree.
However just to say it again because I see the question everywhere.
YOU CAN NOT RESET KNOX TO 0X0 AFTER IT HAS BEEN TRIPPED TO 0X1.
There is a root method that doesn't flip the knox flag though if that is a concern.

I've never had issues when just rooting a device granted I've only had the s3 and note 2 and now the note 3. But with the note 3 if you use the auto root method it will trip knox and that can't be undone and will void the warranty. The root de la vega method will give you just root access if it's what your looking for with out messing up knox.
Thanks guys. Yeah, like I said my buddy's allshare cast stopped when he rooted, so now he's reluctant to do that again. I know about not accepting OTAs. I think I am going to wait to see what other root methods may crop up, and also see if anyone finds away to reverse any accidental knox trips. Right now, i'm just enjoying the damn thing lol! Thanks all.

If your knox is already flipped no need to wait for a new method. Just cm auto root. Use xposed to set system status official. And optionally get supersu pro and select the keep root ota option or don't update to any ota .the files will be in the development section to flash after its released. Like this and you should be 100% functional and stock/rooted.
I'm currently rooted with the vega root .status official. And everything appears to work for me including allshare.
There is always a risk with changing anything. But in my opinion the benefits out way the risks. And all of this is easily undone by just flashing back to a stock system.

Hi all, thanks in advance for any help on this. I have a few general s5 rooting questions. I'm an experienced 'rooter' having rooted and installed custom ROMs on many previous devices.
- I've ready that the s5 has an 'e-fuse' that gets 'blown' when the device is rooted. this then voids the warranty and prevents things like Fort Knox from running. I get that, and understand the risks. But, I've also read that the lollipop update will remove root. These two things seem to contradict themselves.
- on other devices I've rooted, I've then installed a custom ROM. I don't plan to do this with my s5. I haven't been able to find much written on the experience of a rooted s5 running the samsung stock ROM/firmware. I'd like to use something like xposed to change parts of the ROM (like the white background that's so pervasive in the s5 flavor of lollipop). I'm curious if anyone is running lollipop on an s5 that is rooted but running stock samsung firmware and xposed.
thanks!
Rooting won't trip Knox. Installing a custom recovery will. If you have insurance on your device tripping Knox doesn't matter, your covered anyway.
thanks!

very interesting, thanks! can I run xposed/titanium backup pro/other root things without a custom recovery? all I'm really interested in is modifying Samsung-dictated things (like apps that can't be frozen and colors/elements that can't be changed) + making complete backups to the SD card. If I recall from my previous experiences, a custom recovery was the way to create a nandroid backup...but I think perhaps titanium backup pro can do that from the android front-end (with root).
I assume that I should wait to root until the tmobile s5 gets lollipop? i.e. that update will kill root?

Right now there are threads that show you how to get rooted lollipop on your phone without tripping Knox which basically involves downgrading the kernel so you can root with towelroot, then using mobile Odin to flash lollipop and inject root in the process. It seems people are able to do this without issues. To this point, I do not think that anyone has found an exploit for lollipop.
The problem you will run into is that Xposed still does not run on lollipop so you cannot do much in the way of customization. Most of the G900F ROMs can run on the G900T so you might poke around in those threads to pick up more info.
Hope this helps a little.

System runtime is different. Art for lollipop compared to dalvik.. So it's not compatible as of now

are you sure ? I have been able to downgrade. towelroot and flash lollipop and it boots but supersu does not work properly. root apps ask permission and supersu grants permission but the apps dont actually work

I don;t know where you heard that rooting won;'t trip Knox but I beleive you are wrong about that At least I know that Flashing cf auto root - flashing recovery or flashing custom roms all trip knox. If your phone can use Towel Root - that rooting process does not trip knox - but I am not sure if Towel Root works on Lollipop or on the S5 for that matter. (I may be wrong about Towel Root - I have never used that process so I can't say for sure)
Flashing a new rom via ODIN does not trip knox. It is just like getting an UPDATE from the carrier OTA.
BUT, If you are already rooted - you already have tripped knox - flashing Lollipop will remove root - but it will not do anything to change the fact that you tripped knox on your phone already.
As far as I know everything I have said is correct - based on what I have learned thru reading - flashing and using several different samsung phones -
finally, I see a lot of people paranoid as hell about tripping knox - and I can tell you without any hesitation that I have never had a problem getting service or replacements after rooting a phone - there have been a few times back when I first started flashing roms that I had issues with my phone and I took it in and got a replacement without any issue - once I broke my screen and got a replacement then too - both times I was rooted, running custom recovery - etc.
I hope this helps you
I used towel root on NE6. You can downgrade to that via Odin and not trip knox. As far as flashing 5.0 and losing root. I came from Alliance flash Twisted lollipop and kept root. Then used Odin to flash the bootloader and modem for OB1.
Do you still have Knox 0?
How did you flash lollipop?
So I have been looking and reading I remember back on 4.2.2 kingo was able to root without tripping knox I am now finding it that king root is the only option as of 4.4.2 my question is will this trip knox and if so will it lock down my phone. I saw some other users report that king root tripped knox and they were totally locked out I am not trying to brick or flash the rom I had some of my own tricks but from what I have found they have been patched and trip knox now so my question is does anyone know if its safe to use king root on i527ucubnj1 thanks for anyones reply.
Edit: Should mention this is the ATT version.
Does anyone have any idea I see people are viewing the thread but no replies. Trying to avoid bricking the phone and I dont want to jump on this without knowing more because its a hit and miss on all the other posts.
Well I couldnt get an answer from anyone so i took the leep. Don't let the phone screen timeout just keep it awake and working you can change the settings or just keep tapping an area of the app while its rooting. It does say on the program its not rootable but if you root it the root will work as for tripping knox after installing a status checker because im to lazy to check it by rebooting my counter is still 0x0 so we are still good. As for rebooting it I did a reboot right after rooting it I did not get a custom lock as I use to before so I am not sure about that however I did get an "android updating" message could just be random. This was running the 4.4.2 version with all and most current samsung policy apps installed updated all the apps last night.
So with that all being said seems the root held through a reboot and seems to be running fine. I will post and update if any changes happen.
Update: While i dont know if its related I opened kinguser which informed me about knox being active rather than answering cancel or deny I just held home and closed out all apps then I did a second reboot. After the second reboot I now have a custom unlock icon at boot. After a third reboot it seems to be holding root with a custom unlock icon. Shall keep people posted with more updates as I go on if anything else changes as I said above.
I'm looking for some help/advice. I did search and didn't find anything on this although I would think it would have been covered before so my apologies if I missed it and it's already been answered.
I'm currently running Stang5Litre 5.0 OC1 V2 which I installed with Flashfire and I'm having a lot of issues with Good For Enterprise and it's root check. I can get it to work with Xposed as long as I stay on an old version of Good, but I've had two accidental upgrades that triggered a compliance failure and it's a long process with my work to get a new pin to get it going again. Using the detach from market in Titanium doesn't stick. I'm also interested in using Android Pay and can't get that to work at all. So I'm now considering getting rid of root. There isn't that much I do anymore that truly requires a rooted phone other than I really like being able to get rid of all the bloat and being able to freeze and unfreeze in Titanimum.
So my question is what options do I have? Can i fully unroot a debloated ROM or would I need to flash a stock unrooted OC1 ROM? Also, is the fact that my Samsung boot screen shows as unlocked an issue? I know that simply removing SuperSU isn't enough. I don't want to do anything that is going to prevent me from changing my mind down the road and going back to a rooted ROM which I know means not installing anything after OC1.
Any help would be appreciated.
Thanks
After doing a little more research on Good, I think I have no choice but to flash a completely stock unrooted ROM. Apparently it checks too many things to simply remove Root. So what are my options for going back to stock and still keeping the ability to root down the road if I choose?
Thanks
I started to think about rooting my g960f, it is a week year old device and the ads in apps annoys me so much. I will be using root to disable bixby through root uninstaller, if you have any other suggestions please tell. also I will be using mother of adblock, if you have any other suggestions please tell. I still have some questions.
- Is there any way to root the phone without custom recovery?
- will I be able to install system updates if I root the phone? if not how am I supposed to install them when the device is rooted?
- will it lose any of its features? if yes, which features?
- will I be able to go full stock again and gain all the lost features back?
I wont be installing custom rom as I already liked the stock rom but it needs some modification. I am sure that most of the people has the same questions in their minds so your answers would help many.

As long as all you did was root the phone and did not change the OS to a custom one you should be able to get OTA updates. You should be able to install OTA updates normally, but you will loose the root install and have to do it again. Since OTA updates may patch any exploits a root install tool may use you might not be able to root the phone again (at least not until the root utility is updated to use a different method) after an update, so keep that in mind.

Once you root you might very well trip Knox. If Knox is tripped Samsung Pay, Secure folders is what I can find Google Searching and searching the forum here as what wouldn't work Samsung app wise. S-Health would also stop working, but I've read about potential ways to make S-health work again. I am not sure if those ways still work or not.
Other apps (financial, etc) may not work if the phone is rooted..

Sort of... Knox secure apps like S-health, Secure Folders, Samsung Pay will not work. Once you trip knox they will not work on the device ever again. This is because once knox is tripped it is tripped, it's a hardware e-fuse. You can not fix it nor reset it.
Other apps that just detected whether root is installed (or being used) should return to normal
thank you so much for the reply, lastly do you any suggestion for rooting? like the best way of doing it or use this guide and such.
Why root the device? You can use Adhell3 and block all the ads using knox itself

Personally I don't have a suggestion on a root method for your phone, but I do suggest you do some research on the subject. You can also look in the Galaxy S9 topic on XDA as that is the model you said you were using (G960F). In all honesty your gonna want to read up on what the process entails, what issues you might encounter and the risks involved... This is kind of a one way trip (metaphorically and essentially literally speaking) because if you trip knox (which you most likely will) you will void any warranty as well as permanently loose rather useful functionality on the phone (Samsung pay does come in handy IMHO). Not to mention root weakens the security of the phone and if your not careful you could (not saying you will, but could) run into a lot of problems.
Granted I am not saying you shouldn't root your phone but I am suggesting that in your case there is a more simpler method of doing what you want to do. Adhell3 was suggested and it's an app I use as well. Adhell3 will allow you to configure knox to do what you are seeking.. Knox can be configured to serve as a system wide ad blocking and it can be used as a way to disable apps on the phone (including bixby). There is more it can do, but I would suggest reading up on it (I can't give you all the answers, your gonna have to discover them also). Since your not trying to install an custom OS or changing cpu governors, cpu frequencies or anything Xposed related I would suggest looking into Adhell3 since that will do what you want without messing with Knox (or any potential issues with your phone from rooting). Also Adhell3 is not a permanent change to the phone, it can be fully removed, it doesn't weaken the security of the phone by allowing root access to the Android OS and file system on the phone and it will survive OTA updates.
Also if your looking to cut down on advertisements in applications I would suggest not installing as many.. Adblocking whether by hosts file or Adhell3 works by blocking the dns lookup of an advertisement. Both methods are not 100% perfect because if an advertisement comes from the same domain as where you are accessing (like facebook or Youtube sometimes do) then the advertisement will still be shown. Still to cut down on advertisements I would suggest going with Adhell3 over root.
- Is there any way to root the phone without custom recovery?
Nope, that means also that once you decice to flash custom recovery your knox will be triggered 0x1 in bootloader and it cant be reversed by flashing stock.
- will I be able to install system updates if I root the phone? if not how am I supposed to install them when the device is rooted?
Most devs here release latest build of their ROMs based on the latest security patches from official stock ROMs. You can just dirty flash the latest build over the previous one.
- will it lose any of its features? if yes, which features?
Samsung pay and secure folder. However you can try google pay as an alternative and you can use MagiskHide to make apps work even if the phone is rooted.
- will I be able to go full stock again and gain all the lost features back?
You can go back to stock, but you wont be able to use the features mentioned above. It's a one way irreversible process.
