Last night I tried to flash the Cyanogenmod Installer without success. I tried multiple times and each time I kept on getting this Security Information message on my phone: "An application attempted to access system on your device without authorization. This attempt has been blocked...."
I did delete the antivirus app on my phone and so I know that it isn't that. Could this possibly be Knox? We had been told that the CM team had a workaround for those I747 on Android 4.3, like mine.

If you're rooted, download SuperSU from the Play store (I rooted, but the version of SuperSU that was installed was an old version and needed to be updated by manually downloading from the store). When you run it, it will detect that Knox is running and offer to disable it for you.

I wasn't able to find any way to get around Knox without rooting, but I may not have looked hard enough.
If you're willing to root first, CF Auto Root was super easy to do:

Thanks for the reply. I have never rooted not flashed a rom and so I thought that the CM Installer would be an easy way to get started. However, basically like everyone else, they ran into issues with phones that had been upgraded to JB 4.3. They recently posted that they had found a way around it but I started to wonder if in fact they had when I got the message:
"An application attempted to access system on your device without authorization. This attempt has been blocked...."
I was trying to ascertain whether the message was due to Knox or another program?

That *is* a Knox message, for sure.
So it looks like the Cyanogenmod team were not able to circumvent Knox for their CM installer. It's probably just a matter of time. Here is the full Knox notification:
"An application attempted to access system on your device without authorization. This attempt has been blocked. Updating your security policy may solve this problem. Deleting applications obtained from unauthorized sources may improve security."
There are three options at the bottom of the screen: Cancel, Update, and View Apps.
Update: I was able two days ago to use the Cyanogenmod Installer and I am now running CM!! First time for me to ever root and flash a Rom (I was an iPhone guy).
The phone is faster and smoother. I never liked the Touchwiz lag and most of the Touchwiz features worked inconsistently. The only thing that I miss is the camera. I have not found any bugs yet and so am very happy thus far.

OK, so I did something stupid.
I was running 4.1.2, Rooted with a Perseus Kernel until I got "ambitious" and downloaded 4.3.
Everything went really well and the device rebooted fine and is working really nice and fast.
But, of course, I lost root, and the binary counter indicated "1" which didn't worry me.
So anyway, a couple of hours I decided to try rooting again with the same process that I used before since I still have the Windows Partition on my Mac and that went well too. Took all of five minutes. Now, the Binary Counter reads '2'.
BUT comma... None of my rooted apps will work. I keep on getting the dialogue... "Sorry, I could not acquire root privileges. This application will *not* work! Please verify that your ROM is rooted, and try again.
This attempt was made using the "/system/xbin/su" command.
After downloading 4.3, I didn't enroll in "The School Of Hard KNOX" and didn't install it, or whatever it is that you have to do to activate it... the window came up, but I didn't go for it. I just bypassed it, and it's not running (At least it's not under the running apps column).
This might be connected, but I also got this message after rebooting earlier, having to do with Google Play Store.
"Samsung is continuously working to improve the security policy on your device. Make sure you update the Security Policy on yur device.
Make sure your device is protected by updating the Security Policy to the latest version from Samsung.
And then I got a message having to do with the "XPrivacy App".
I just uninstalled Titanium Backup and The Titanium Backup Pro key, and reinstalled from the Play store, but it still gives me the same no access message.
Custom Binary Download: Yes (2counts)
Current Binary: Custom
System Status: Custom.
This just happened when I booted.
SuoerSU
"There is no SU binary installed and SuperSU cannot install it. This is a problem.
If you just upgraded to Android 4.3, you need to manually re-root - consult the relevant forums for your device."
Kinda stumped.
How to root Samsung galaxy Note-2 N7100 < Android 4.3 >
Hello bro ..
i have solution for you ..
Contact me . [email protected]
So, I just got am SGH-T747 S3 yesterday, and was poking around in all the new settings, when I came across "Software Update". I wasn't sure if this meant firmware or what, but I went ahead and let it download what turned out to be 4.3 (whereas I was on 4.1.2 or thereabouts).
Then I tried to root it today, with a couple of methods but most recently CF-Autoroot. I haven't flashed any ROMs or done anything else beyond this yet, I just wanted my Ad Blocker. And then I start getting this business about "SuperSU has stopped", and the "An application attempted to access system" nonsense. So of course I Googled it, and came across a number of different articles/posts about this problem, including some on XDA, none of which seem to offer any solutions.
I'm not really sure at this point how or even if this problem can be fixed or not. I've read that you can't downgrade to a lesser ROM version (?). Also, I'm not sure if flashing CyanogenMod (which is what I eventually want to do) would solve the problem, and I'm not about to try it for fear of what other surprises I might encounter.
But if for some reason I can't have root, I'd at least like to be rid of this incessant notification that the program has been blocked. TIA.
Well, if you want adblock, there is a VPN called Spotflux that doesn't slow your speeds down, has adblock, and is free.
About the root issue....I wouldn't know as my i747 is in a coma of the QHSUSB - DLOAD disease.
You might wanna try the cyanogenmod installer in google play to see if your device is supported ( proceed with caution)

Thanks, that is an interesting alternative in the interim. As with everything ad-related, it doesn't work everywhere (I guess they are pulling ads from custom servers or whatever), but it does seem to work with some programs. I've had the same issue with AdBlocker too.

if i remember correctly, in settings>security you can disable the notification of supersu being blocked and now you can access root. happened to me when i first updated
I used cf autoroot and then installed supersu from the play store. When I opened supersu it asked me if I wanted to disable knox and I pressed yes. Then I installed titanium backup and froze knox.

Hello to all,
I recently rooted my sgs3 sph-L710 v4.3 and am experiencing some problems. Whenever I try to open superusers it automatically closes, and I receive a notification saying, "security notice an attempt to access a secure area on your phone without authorization has been blocked." After doing some research online I discovered that the 4.3 version is protected by KNOX. Online sources state that in order to defeat the KNOX system you must update supersu, but I am not sure how to do that. Whenever I download supersu from the Google play store there is no option to update it. I would really appreciate any help thanks.

Have you checked to make sure you haven't lost root? When you install an app from Google play, you get the latest version.
sent from my GS3
Also, have you actually opened up the SuperSU app? You need to open it up (not just download it) so that it will prompt you about disabling Knox, and it might also prompt you to update the binaries. And which custom recovery are you using? If need be, you can flash the SuperSU zip from recovery, and if you are using Philz Touch (HIGHLY recommended) there is an option to have it check for root before booting back into system.
I did it!!!

Yes I finally got it to work I just re rooted the device and superuser was gone. However, i downloaded supersu and it prompted me to update, i did and I was able to bypass knox! I think it was a problem with the method I used to get my phone rooted the first time. The video tutorial I watched the first time told me to uncheck the 2 boxes that come prechecked on odin i believe one of them was auto reboot i cant recall the other one. Then I took out the battery of the phone and selected the root file through mod recovery mode and that was it. The second time around I left the boxes checked and my phone auto restarted. I then downloaded supersu updated,rebooted, and Visalia!!!
Thanks guys I appreciate the help.
[Q] Root "disabled" itself!? (Rooted phone that is no longer allowing root access)
Anyone here with this phone (or any) - that is rooted - have it just seemingly act as if it is no longer rooted? or unjustly denying root access for no apparent reason....
Have been rooted since purchase and have never seen or had any issue with this..have flashed custom recovery and rom's hundreds of times...no problems...currently using Task's latest KK 4.4.4 rom and had no issues from beginning...
It comes with SuperUser...i do usually install SuperSU instead but hadn't tried yet...it was fine and apps that needed root appeared ok..even SuperUser has three or four listed apps in the "allow" section...but all of a sudden I can't seem to give root access to anything else now..
First noticed the other day when trying to sideload an apk..couldn't...tried to do it manually by just copying it to system/apps folder and that's when the first message came up saying "it appears your device may not be rooted"...quite odd I thought.. i then tried to install SuperSU and it when SuperUser popped up to give it allowable root access it would only timeout and say denied...i then tried a bunch of other apps that require root and they would all just get denied by SuperUser...
Anyone seen this before or know what causes this and/or how to fix?
THanks for any help or suggestions
ps.. i'm no noob and have been doing this a long time and have rooted/modded dozens of phones, hundreds of times...but this issue is a new one for me.. IF i have to completely wipe and even go back to stock image and then start over to re-root and re-mod... I will and can do so easily..but that would be last resort if necessary...thanks!
In SuperSU, try the clean-up for reinstallation option.

when launching SuperSU it needs root access to begin with and SuperUser wont allow..this clean up for reinstall is still doable?
Get the recovery flashable SuperSU then. It'll get rid of the other one in the process. You can get it from my sig, but it'll need to be updated after.
I'm brand new to this website, and have only signed up because I cannot find a solution for this problem. I have always used the forum to get answers, but never though to join! My Galaxy Tab S 8.4 4G T705Y was put through the CF-Auto-Root method, and no a glitch at all. Very smooth. By the way I checked the ChainFire website to make sure I was using the latest. When my device started up I noticed, as I have done before with my Nexus phones, that SuperSU has been added. Good Sign!
But when I open SuperSU I was prompted to update the Binary. Then I pressed 'continue', used the 'normal' method, and waited. It then asked me if I would like to Disable Knox. Yes I would! FAILED TO DISABLE KNOX. Shut down SuperSU. Unhappy Face. As you can see at this point, I am not very up to speed with my rooting knowledge.
So then I decided to select the 'never' option to updating SuperSU, and still it failed to update the binary, I'd say due to Knox stopping it from gaining access.
So my pickle is this: I can't update SuperSU because Knox will not allow me to use SuperSU. I cannot simply hit yes to disabling Knox in SuperSU, as that didn't work for me. I also tried finding something called Knox on my tablet and it seems to be very elusive. I tried updating SuperSU on Play Store also, but to no avail!
I am also unable to use any third party app to do so as I need to grant them access in SuperSU before they can begin! And around I go...
There is a guide here http://forum.xda-developers.com/showthread.php?t=2540761 but it's not for my device so I'm a bit hesitant to start trying random things, as my device is working great atm!
Any info or help would be greatly appreciated!
Look in the android development section for my updated builds of cf_autoroot and flash that.
If you still get issues flash supersu v2.49 with twrp.

That seemed to at least do something, now it's saying there is no SU Binary installed. So I googled how to do that, then saw you needed TWRP to do so. And in order to get that, I needed the SDK and JDK, so I got them, but then in then couldn't find any of the right files in the SDK folder when trying to install through command prompt. There is a cool program called TWRP Manager that claims to do it, but you need root access. Lets not go there. So method 2: you needed to use a program like GooManager. But even then root access seems to be the order of the day. Ive tried Terminal Emulator and Package disabler also.

Then you flash this with twrp http://download.chainfire.eu/743/SuperSU/BETA-SuperSU-v2.52.zip

So this is what I do.
Power off device.
Restart in Download Mode.
Use Odin to install the cf-autoroot-twrp-t705.tar from the development section.
When device restarts I put supersu version 2.52 (beta) on the devices memory, then turn off device.
Restart in TWRP Recovery mode, hit install, choose the zip file, install, reboot device.
When device reboots, open superuser and get this message: "There is no SU binary installed, and SuperSU cannot install it. This is a problem! If you just upgraded to Android 4.3, you need to manually re-root - consult the relevant forums for your device".
I swear i'm not blonde. :good:

This doesn't make sense. Something is amiss if you can't root with cf_autoroot or twrp. You are the only one as far as I'm aware that has experienced this.
