Restoring tablet, ROOT and KNOX question. - Galaxy Tab S Q&A, Help & Troubleshooting

Hi everybody!
I have a Samsung Galaxy Tab S 8.4 that I have rooted with TWRP and SuperSU.
And now I want to sell this tablet and I want to unroot it so that the buyer could use the warranty of the device if needed.
How do I go about doing that? If I unroot it, can the repairmen see if KNOX has been broken?
Sorry for bad terminology, don't know much about rooting.

Not possible to reverse knox. The warranty us void.

Ok, thanks!
How do I go about making the tablet as stock as possible then?
I've installed TWRP and SuperSu.

The best way to get as stock as possible is to flash a stock firmware via Odin! Just download the stockrom matching your device at sammobile.com/firmwares and flash via Odin

I read on this forum that most of the time they will repair your tab even if the knox has been tripped.
The latest KingRoot now has an uninstall feature if you need to return your tab.

It will still say custom. The only way is to flash stock firmware.

Knox warranty void flag

I'm currently using stock MF6 firmware and there is no indication of the Knox warranty void flag in download mode. Does anyone know which firmware introduced this flag on the S4 mini or is it not implemented, yet? I'm asking because I want root access and need to know which prerooted firmwares I can choose from without this flag.

As far as I can tell, there's no Knox flag known on any S4 mini firmware or variant. Definitely mine has no sign of it either. And from what I read, at least ith the S4 it was never transparent, only when the flag appared could you kill it, in older firmwares no matter what you did the flag was never set until you upgraded and there was something considered wrong then.
4.4 is supposed to bring Knox for the mini so it may bring the flag, which could be easier, harder or the same to avoid as the S4, only time will tell I guess. If it's similar, hopefully enough will have been learnt by the time S4 mini get 4.4 that we can easily get around it.
@Nil Einne
Thank you for your reply. Which firmware version are you using?
(I9195XXUA)MG3 (which is 4.2.2 / JDQ39). It's currently the latest for my CSC. I may root soon perhaps using a prerooted firmware (since mine is so old) but I'm waiting to see if anyone has tried it on a 16GB version. I didn't mention before but I guess it's clear now I have an I9195 but I haven't seen any mention of Knox flag seen for any variant of the S4 mini on current firmwares.
My s4 mini (I9195) came with firmware MF7 and was upgraded OTA to MG8.
After that I flashed with Odin to MH2 (Android 4.2.2).
Thereafter I flashed a custom rom (Slim with 4.3.1).
Where and how can I see whether my Knox warranty void might be 0x1 now.
And what if I flash back with Odin to firmware MF7?
Is that still possible without a later upgrade problem?
Curious about your info.
New Rom XXUBMJ7 whit KNOX bootloader (aboot.mbn) and aplications.
After flash this Rom we have on Download Mode:
KnoxKernelLock: 0x0
KnoxWarrantyVoid: 0x0
Like on Note 3 N9005, if we flash something, customer, root, KnoxWarrantyVoid: go to 0x1 and this is not reversible.
To Root
The Root-Kit-V1 install all superuser, SU and busybox but after reboot the SuperSU can't access to system, KNOX not permit.
To solve this we must flash after, on recovery the UPDATE-SuperSU-v1.65.zip from Chainfire. After we have root alright.
My case like on Note 3:
I not need the KNOX, the phone is only for me, then after root I delete all KNOX apk + odex from system/app.
Good luck

[Q] Kingo root help

So i have a Galaxy s4 mini with sprint as my carrier. I'm currently trying to root it via Kingo root app but the problem is that everytime i try, the end result is NeedRoot. I checked my phone and apparently the problem is that everytime I try to root, i get a little shield on my phone saying "Security notice" once it's clicked it states " An attempt to access a secure area on your phone without authorization has been blocked. Make sure your phone is protected by updating the security policy to the latest version from samsung". So how do I remove this policy problem? I just want to root my S4 Mini. Any help/advice is great help, thank you!

If you took all the updates and are on NA7, no. As far as I know we need ODIN/Kies to root now. Ideally, we wouldn't have have taken the update that made Knox an issue. Someone would have dumped update, broken it apart and gave us a zip to flash everything but the bootloader so we wouldn't have these issues.

Hi i have a s4 mini gti9195i with knox rooted by kingo root apk
how can i change from kingo's superuser to supersu from chainfire? The update of the binary fails.
Not fast but 100% good way:
1. Flash stock firmware with odin (remove kingoroot and all it's trash).
2. Use CF-Auto-root or (if you plan to use custom roms) flash custom recovery.
Notice:
CF-Auto-root probably will trip knox flag when trying to disable knox security.

[Q] Modified Note 3? Won't let me update :(

Hey, everyone! I tried googling this for hours and I still haven't found a solution, so here goes:
A couple days ago, I deleted an important image from my T-Mobile Note 3 and I was freaking out, searching high and low for a solution. I read on Yahoo! answers to download DiskDigger, but the device must be rooted in order to install it. So, I tried to root my device with KINGO Root, which totally failed and then my device just went into bootloop and I thought I messed up my device for good. Luckily, on a different thread someone suggested to use the Youtube video GalaxyNote2Root made to unbrick my Note 3. (Even though it was for Note 2, it was the same concept and I did find the stock firmware on samsung-updates for my Note 3.) It ended up working successfully and then I continued to try root my Note 3 using Odin and the video instructions on xda forum (which I should have just done in the first place) and that worked successfully, too.
Now, my problem is, is when I went to update my Note 3 under settings, it says "Your device has been modified. Software updates are not available." I tried using Triangle Away (I don't know if I did it correctly) and also 1-click unrooting my device in SuperSU. I'm a huge noob at this rooting stuff, but what I gathered from all the research I did on Google, I apparently tripped "Knox". When I go into download mode it reads:
Current Binary: Samsung Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x1
So, a couple questions I have are, how do I "unmodify" my Note 3 so I can get updates? Is there a way to reset my Warranty Void back to 0x0? Will this always happen if I want to root my Note 3? Thanks in advance!
you can not revert knox back to 0x0, no method so far for this....
so you can receive updates, just flash through ODIN, the firmware ... I believe all Samsung phones and tablets will tell you about being modified for updates, if you rooted the phone.

well, you can just reodin a stock unrooted firmware, and then otas will work again, but Knox is basically always tripped.
why even use odin when you have SAMSUNG KIES. put your phone in download mode first, load KIES on your computer, then go to tools>firmware upgrade and intialisation and then follow the step by step direction.
if this helped just press the thanks button!

Can you link me to an unrooted firmware? And when I flash my device with the unrooted firmware, do I uninstall root first or will this just take care of the whole thing?

I tried unrooting the phone and it was still not letting me update because it was still "modified". I thought this was because I tripped Knox, but maybe I didn't unroot correctly??

when u flash the stock firmware in Odin it will overwrite root, so no worries. just follow the first part of this guide. obviously don't flash root, or custom recovery. just follow the first part of this http://forum.xda-developers.com/showthread.php?t=2765014
or, you could also go to a website called sammobile and download the latest ne6 firmware. The link I provided is also the latest ne6 firmware guide, and like I said just follow the guide up to the the root part and you will be good. it will over write root, and whatever else. good to go.

yea, you must of done something incorrect. now, you won't have any updates after following the ne6 guide, as you will be on the latest firmware. but if you continue to stay on it you will indeed be able to grab otas when they come. personally I would just root, stay rooted, and keep up to date with roms, and kernels, and all that crap.

[Q] Rooting Questions

Hi guys,
I am new to the xda forums and I have been researching about rooting my note 10.1 2014 p600 (WIFI). I have three questions about rooting my device.
1. How would I update my tab with root? I heard you can't get OTA updates.
2. What is the best and safest way to root?
3. How do I get TWRP and is it good?
I haven't installed knox on it yet and I am a beginner to linux and have done research so I know what root is.

Ok, First, for the p600 if you root, you will trip Knox which will void your warranty and there is no way around this and this is the only way to root your model (p600), If you don't care about warranty then continue...
1) Download this file https://dl.dropboxusercontent.com/u/11938873/CF-Auto-Root-lt03wifi-lt03wifixx-smp600.zip then unzip, you will see this file CF-Auto-Root-lt03wifi-lt03wifixx-smp600.tar.md5.
2) Turn Off Tablet, Hold Volume Down + Power. Follow the instructions on the screen to get to download mode (Odin mode).
Rooting Instructions
1.Flash the CF-Auto-Root-lt03wifi-lt03wifixx-smp600.tar.md5 file with Odin v3.09 (put in AP slot, don't change any other settings, click start)
2.Let it do its trick! boot up then go to play store download and install supersu in order to update supersu to the latest binary.
3. Boot back into Odin mode and flash TWRP version 2.6.3.3 found here https://goo.im/devs/OpenRecovery/lt03wifiue/
That's all!

Knox is just a shortcut to the install link, Does this mean it's not installed or is the shortcut just extras (I don't know how to post screenshots).

I don't understand what you are saying???
When I said tripped Knox void warranty is that your device detected that you installed unauthorized software which tripped the knox counter. You can see this by boot into download mode (Odin mode) and you should see a line like this:
Warranty bit: 1 (factory is 0x0)
I hope that what you're asking!

Yup.
ok, now i'm getting confused.
my p600 is still on 4.3 jellybean. but from what i read, as long as did not update to kitkat firmware, i can still unroot and reverse the warranty bit bcoz they don't have knox yet. but it'll be too late if i updated to kikat right? btw, i used cf-auto-root.
just weeks ago i rooted my p600 and flashed stock recovery, so now my p600 thinks its stock official firmware, even say so in about device.
i haven't tried unrooting it yet to confirm that i can get warrenty back by flashing back whole stock firmware bcoz i don't want to redo all settings again. but thats the impression i'm geting.
anyhow if i can't really reverse that warranty thing i don't really care anyways. i warranty my stuff better than they do it, and since i think i can still get updates, it bothers me even less if its unreversible. but in the case if i'm right, and i can reverse that warranty bit. maybe one day i'd like to update to kitkat. then what? i'll have to have knox in my system and i can't reverse warranty counter anymore?
is there a way i can update to a custom kikat firmware (one day) and not have knox so i'll still be able to get warranty back?
i kind of realized the dilemma i have here since if i own the device for more than a yr, my warranty wouldn't matter anymore. am i just thinking too much and worrying myself?

Yes you're confused!!. Knox has nothing to do with warranty bit, once this tripped, you can't undo doesn't matter you on 4.3 or 4.4.
I'm a little confused on a few other issues. I have read over 40 pages on another thread here about rooting etc and I couldn't find the answer to a few questions. I've just successfully rooted using the most recent instructions (P600 - CF Auto root) but in earlier instructions (about a year ago) you had to also install the stock recovery file using Odin. Is that a necessary step? Is it needed for OTA updates? Since I've read that OTA updates will unroot and possibly prevent you from rooting at all, is it best to just forget about OTAs and flash up to date files from this site? Is it also prudent to turn off auto updating in the settings.
If I'm not installing custom roms and backed up using Titanium Pro do I really need to install TWRP? Any other benefits other than nandroid? Thanks

Once you rooted you can't use OTA update any more. So the easiest going forward is to flash TWRP and use it to flash pre-rooted rom from this site.
Thanks buhohitr
I guess I'm installing TWRP tonight. There are many versions up to 2.8 I think. Which one do you recommend for P600? I've tried searching for "installing TWRP" but there were no obvious hits like there were for rooting. Which is the key thread?
To my first question, I'm assuming that the later root methods automatically installs or leaves the stock recovery as earlier methods needed to load it. Am I right?

OK found the thread and I just read the last 55 pages (that took a while) and boy is it scary. So many problems. Touch not accurate, inverted screens, certain versions failing eg 2.7, can't access external SD card, continual looping, booting into the old recovery , OTG cables not working, time zones can't be set properly, some say turn off autoboot in odin and some say don't change default settings etc etc. the list goes on and on. I likened it to a bushfire or tornado. Some houses still stand and some don't and you want to know the silly thing here, I am an experienced computer teacher with a degree in computer science and I've upgraded firmware on over a hundred devices over the years and yet all this rooting and recovery stuff is another world. The rooting process, admittedly, was a piece of cake and the instructions for flashing TWRP seems easy too but after that there seems to be so many problems. So hit and miss.
All i want to do is load TWRP on a P600. I will only load custom ROMs when a new firmware version comes out. Can someone alleviate my fears who has successfully loaded TWRP recently on a P600 using ODIN without massive tweaking to get it going. What version TWRP did you use and did you turn off autoboot or not?
PS Have I posted this in the correct section?
Took the plunge and loaded the latest TWRP 2.8.1 and it worked perfectly except I could only back to the main SD storage and not my extSD. I ended up, as a work around, moving the backup files to the extSD drive and PC.
I think I was worried unnecessarily.

Noob needs helps to get back to stock :D

hi guys,
i'm asking for your help, I want to get my tab pro 10.1 Wi-fi back to stock,
I explain my problems, I rooted successfuly with Odin and I must say I didn't get all the informations before doing that, because I ran into porblems like random reboots, freeze of the tablet and it's related to the fact that I froze Knox with SuperSu. (and more of that I didn't knew that it would void warranty tripping that Knox counter to 0x1, and block updates :'( )
So now I want to get completely back to stock, and make that Knox work again and don't want to be rooted anymore.
If someone can tell me how to do it, it would be awesome
thanks to all., and have a nice day.

Download stock rom for your device from Sammobile web site, flash it using Odin then do a factory reset, you will get stock system back but KNOX will alwasy show as tripped you can't reset that to 0x0, it will remain 0x1
