Going to cut it as short as I can, and I'll probably sound like a noob and annoying at the same time. Can I root my Galaxy S5 T-Mobile 4.4.2 G900TUVU1CNK2 without triggering knox? I don't want to touch anything (no rom or loader or anything) - I just want it to be rooted so I have some access.
If that can't be done, can I root and yet still send back to T-Mobile as a warranty replacement without them charging me?
If I were to root, can I still use the OTA upgrade from Lollipop once it comes out or does it have to be done a different way?
You can root without tripping Knox. Follow @galaxyuser88 here

If you upgrade, OTA to 5.0, you will lose root privileges and have to re-root

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.

I'm new to rooting devices. If I root my phone and don't flash a custom rom, would that still make the flash counter turn and still void my warranty? I don't want custom roms but there are some apps I need to be rooted to use.
If u will root your phone will lose warranty. ..

can you un-root it and still have warranty or is this not possible?

Ok, first what version of Kikat are you running? If you upgraded to 4.4.4 you are out of luck for now. If you are still on 4.4.2 NC5, you can use Towel root. This will give you root access, and will NOT trip KNOX 0x0 !!! However the minute you install a custom recovery like TWRP or CWM that will trip KNOX and void your warranty. REMEMBER Sprint will warranty your device with the KNOX warranty counter tripped 0x1 as long as you unroot the device before you take it in or sent it back to Sprint !!! If the device is hard bricked, there is no way to tell it was rooted and they automatically replace the phone. With rooted access and no recovery you can Debloat the device and run rooted apps. Enjoy !!!

darn I guess i'm boned then. I have 4.4.2 but I used Odin to root my phone :-/
I guess if something does happen to where I need to replace it, there's always the *nuke* method or *it's lost or stolen + nuke* method as i do have Sprint's TEP plan.

I run a stock rooted 4.4.2 NC5 with Philz custom recovery version 6.12.9 hltespr. The device was rooted and warranty tripped the second day I owned it. I was in a Sprint corporate Store a couple of wks ago. Showed the tech my rooted note 3. He said I can't touch that, I said what if I unrooted the phone. He said no problem, now I can warranty the phone. He didn't care that the KNOX flag was tripped at all 0x1. Just can't be rooted when you bring it in for service. Sprint doesn't care about KNOX only Samsung cares about KNOX. When Samsung paid millions to the NSA to design a security system to track and spy on others than they care !!!
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
Sent from my SM-G900T using XDA Free mobile app
This does not work with lollipop

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?
I have found the root directions that was posted on this site for rooting my s5 with 5.1.1. But I have 2 questions I was hoping someone could help me out with here. Please forgive me if these seem like stupid questions, as I have only rooted one phone before some years ago.
1 There is much discussion about rooting the s5 will "trip Knox". What exactly does this mean if you do root your phone? Will you have constant error messages popping up on device about Knox? Can you simply uninstall Knox after root?
2 I currently do not have the Tmobile hotspot feature activated on my s5, but I do plan on adding it on later. If I root now, will I still be able to add the Tmobile hotspot feature on my s5?
Much gratitude and appreciation ahead of time for any and all info.
Thanks,
Dave
Hi nissandave,
1) Knox, in terms of the s5, has two meanings. One in the Android OS, and one deep in the firmware of the device. You'll find in most roms that the Android Knox application has been removed, which most people prefer. "Tripping Knox" refers to modifying the firmware of the phone, where the counter in download mode goes from 0x0 to 0x1, voiding your "knox warranty." Knox is tripped when you flash when you flash a custom recovery. Root AND know can be achieved though ODIN in some cases, but you'll be stuck on a stock rooted rom (no CM, bliss, etc) Tripping this switch has no serious repercussions in terms of your phone being fully operational, but there have been VERY few reports of Samsung not performing warranty exchanges for devices with a tripped knox counter. The counter is also impossible to reset, and once tripped, will always be tripped, no matter what rom, BL, tar, or md5 you install.
2) Yes, and as a matter of fact, some roms have a workaround version installed to where you don't have to activate it through tmobile. It just works. Twisted v7 in the G900T dev sections is once of these roms.
From what I I have found and read about twisted v7, you must be running 5.0. How do I get my phone back to 5.0?
I need to root my Galaxy Alpha to edit just one system file, and then unroot it so I can still use apps that don't work on rooted phones. It seems like rooting is not a problem, however I couldn't find any information on the internet on how to unroot a phone that has CF-Auto-Root applied. Can it be done?
Or alternatively, is there a way to gain root access only on adb so I can edit the file this way? Temporary custom recovery maybe?
By the way, tripping the knox flag, losing warranty etc. is absolutely fine by me.
