issue with KNOX on my S3 - Galaxy S III Q&A, Help & Troubleshooting

Hi, I had a phone which had a corrupted EFS. I followed the procedure here -> http://zidroid.com/how-to-fix-failed-to-mount-efs-for-galaxy-s3-gt-i9300/ and the unit is now booting fine. but it is factory mode. I saw the follow up post regarding how to remove the factory mode, but that requires root access. I flashed CWM recovery on my phone, and also SuperSU. However, after I had flashed superSU, KNOX came into the picture. I cant run SuperSU because of KNOX. So I searched how to remove KNOX. Since I still hadnt had ROOT, I tried to remove it using the steps outlined by samsung. However, when I open the KNOX app in the appdrawer, it says It hasnt been installed yet and I need to install it... so I try to install it, but after downloading it cant install it due to it being in factory mode!! (!!!)
So now I am stuck. I need to exit factory mode, and I need root. I cant root because of KNOX. I cant disable KNOX because I need root (or need to install KNOX to remove it??)
I also found a zip file Degrated_Shadow's_KNOX_removerV2.1 but it didn't work..
any help would be appreciated!

The i9300 doesn't have knox.

It does on 4.3.. I get a "An application attempted to access system on your device without authorization" it has the shield logo..

No. The i9300 does not have knox on 4.3 or any other version.
Either you don't have an i9300 or have some other software installed.

[Q] Connect device to Odin - previously f. reseted

Sorry if this has asked before a thousand time, but I'm not sure if what I've done before changed anything from standard operation.
I once did factory reset the phone - its already rooted at the time. It was since that time both Heimdall and Odin can't get access or permission to load things into the phone.
The device was rooted using CF-Auto Root, currently have SuperSU, Titanium Backup, Root Browser Lite, Rom Manager and TriangleAway installed. No CWM and such. Just to note what happened to the phone after factory reset, the device status switch to "Normal" and in download mode, it shows "Custom Binary Download" to No, "Current Binary: Samsung official", and "System Status" to Official ; Everything except binary was before factory reset shown the otherwise (no to yes, official to modified).
Once again, I say sorry if this thing had asked before.
Thank you !

[Q] Problems with rooting

Hey there. I want to install CM11 to my I9205 but I can't seem to root it. I've read most of the threads about it, but nothing works for me. It just shows me a security warning from KNOX and SuperSU says that there is no binary installed.

You probabely have OTA update recently... now you have ROM with Samsung KNOX security system and with new bootloader. If you want to root your Mega and you are willing to accept irreversible tripping Knox counter (= warranty void) you can find many tutorials how to root ypour phone and disable Knox. Basically it needs essentially to instal custom recovery using Odin and then installing Super user from recovery. But ask yourself the troble to find exact procedure.
Note: now you can not downgrade your firmware to version without Knox. Any attempt will end in bricking your phone.
So if you want CM11 you have to root (with tripping flash counter = warranty void), installing custom recovery CWM or TWRP and then installing CM11 ROM nad choosen version of gapps (ROMs AOKP or CN type are lacked all Google apps so if you wnat it you have to flash it separately)

Thanks for the reply. I've managed to install a custom recovery, but I can't seem to make the root work. I have tried both CWM and TWRP, and still can't get SuperSU to work properly.

try to use this information.
As I said in other place - in such situation the best way is to start completely anew:
- Download firmware (e.g from Sammobile)
- Install it by Odin
- Install custom recovery
- Root phone
In provided links you should find detailed description how to do it. Bear in mind so for successfull installing custom rom's you HAVE TO disable KNOX e.g as is decribed there

My phone is giving me problems for root

I have a Samsung Galaxy S3 T99L with 4.3 version.. I recently decided to try to root it (I rooted my old phone, but since this one was new i dint root it before) and its giving me headaches!
I rooted it with CF Auto Root for the same model, I followed instructions (using Odin to root), and when my phone resets, I think its KNOX or the system itself blocks SuperSU. This is another problem, I open SuperSU and the first thing it appears is ''There is no SU binary installed and SuperSU cannot install it'' and then it closes and theres a notification that SuperSU got blocked by the security thing. PLEASE HELP!
Btw: I cant find stock for t99l

Samsung Galaxy S II (GT-19100) Gingerbread | Rooted, but superuser not working

Hello peeps, evilbeef here!
So yea, I have rooted my phone a while a go I have used Odin v185
and I used Speed Kernel S2 K-2 -21 as the PDA file. I have found this on GalaxyS2 Root webpage
I have successfully rooted it, basically I have rooted so many phones using Odin. :laugh:But this one is different. I already have Superuser app (from google store) before I started rooting it. After I rooted it, my phone rebooted automatically. In the Startup, The phone has yellow triangle. My Phone works normally.
BUT THE PROBLEM IS, THERE IS NO REQUEST OF PERMISSION SHOWING, I ALSO USED ROOT CHECKER, IT IS NOT WORKING, IT SAYS ROOT ACCESS IS NOT PROPERLY INSTALLED. ALL OF THE APPS I DOWNLOADED THAT NEEDS ROOT PERMISSION ALSO DOESN'T WORK.
BUT ONE THING I AM WANDERING ABOUT IS THAT MY KERNEL VERSION CHANGED.
IT SAYS THAT: 2.6.35.7 [email protected] #k2-21
But also when I go to recovery mode, I can flash CWM recovery automatically.
The only thing that doesnt work I think is the Superuser.
I also tried checking su binary vlegacy. I also try to check for updates but superuser keeps me forcing it to close.
I think I am only having issues with Superuser I think. How Can I fix this? Please Help
Uninstall supersu from you phone.
Download supersu from this link- https://download.chainfire.eu/696/SuperSU/ Copy paste it into your SD card.
Boot into cwm recovery and install the supersu zip file you downloaded.
Thanks for the fast respond bro! I was thinking about the same thing tho, I just want to have confirmation from others if this thing would work! HAHAHAHAH thanks mate! :--------)

Can't fix root. Do I need to flash recovery again?

So I just successfully installed CM13 on my i9300. Everything works fine, but I just found out I lost root rights.
I went and downloaded the Super SU app from the PlayStore, launched it and that gave an error that there's no SU binary installed and I need to manually root again.
So I downloaded UPDATE-SuperSU-v2.65-20151226141550.zip, put it on the sdcard, rebooted into CWM Recovery, installed the zip and booted back into the system (when prompted to fix boot I selected no as recommended), but now I STILL HAVE NO ROOT RIGHTS and the Super SU app still gives the same error.
Is there a specific SuperSU.zip I should be installing in recovery to make it work?
Or is something wrong with the recovery and do I need to flash that through Odin? (I don't think this is the case though, as flashing CM13 and gapps went completely fine)
Thanks for any isnight and tips

In Developer Options I have set Root Access to Apps and ADB it didn't give any error, but doesn't seem to be doing anything either... In file manager I can't reach root, Root Checker app fails, Super SU gives than binary error, and another app that requires Root Access says I don't have it as well..

Flash rom again and dont flash SuperSu its better now without using SuperSU
I got the same problem. I tried to root with odin again but it didnt work...
Flash cm13, wipe data and cache and flash cm13 again. Cm13 should be pre rooted.

Hi Guys, I have the same problem too after CM13. Unfortunately rooting again with ODIN flashed stock recovery back and am stuck on CM13 now with no root and stock recovery. Can someone help please? Below is the detailed description of what happened.
----------------------------
1. My Samsung Galaxy SIII International (I9300) was rooted and I had CM11 stable/snapshot version there since last 2-3 weeks.
2. Yesterday, I tried upgrading the latest CM13 nightly for my device.
3. While doing so, and rebooting, it asked me the normal message "root possibly lost, fix, yes or no". I accidentally pressed no.
4. Then I noticed after CM13 was flashed, that I do not have root access anymore. Please note that at this point in time, I was not aware that it has to be explicitly enabled in developer options.
5. I came to know that I lost root when I tried to boot in to recovery (CWM) to install gapps.
6. Now, under the impression that I do not have root anymore, I tried to root again with Odin as I had been doing all these days.
- By doing that, ODIN removed my custom recovery (CWM) and flashed it with stock recovery.
- Though ODIN said PASS after reboot, I still do not have root access.
7. Removed cache, wipe data, and factory reset, multiple times but no help.
8. Enabled root for both apps and adb in Developer options, but no use.
9. I also tried KINGO root ( a very popular tool for SGS3 these days) but in vain.
10. Now, am stuck with CM13 and stock recovery and unable to do anything with ROM manager or anything else as I do not have root anymore.
11. Am able to install few apks for whatsapp and facebook for now and living with it, but it wouldn't let me install playstore apk too anymore.
Highly appreciate any quick feedback.
same here after rooting once cm13 by developer option, for some reason i had to use hide my root app, now unable to get root back
Its a problem with the s3, it forgets root. The most reliable is chainfire and sticking with a stock rom.
You must:
Wipe to factory,
flash an original rom via odin,
Boot straight to recovery and wipe to factory again,
Flash original rom again,
Boot straight to recovery and wipe to factory,
Allow the phone to boot.
You must flash at least twice and reset to factory at least twice, even tho I sad it thrice, to kill all remnants of the old rooted rom.
Then you can flash chainfire via odin and go from there.
