So @zander21510 bypass FRP then try disabling knox you can find multiple videos on that you just need to get to Dialer App on your device or just Enable USB debugging.
Hi I have the same Situation as him. I don't have the emergency dialer in my setup screen. I tried the MTP open browser button but it fails. I am only able to go to settings when Knox Enrollment Service gets stuck in Updating Device and setting up work policies because it allows me to show the recent apps and access settings from there. I was able to enable debugging mode though and says that disable knox success. However, after the reboot it's still stuck in Updating device, then it factory resetted itself.

Do you know a solution to this?

EDIT: I have the Galaxy A5 SM-A520F from telstra. It has Work Policies in it.

As you said you were able to disable Knox using app after that it is triggered again I think it is highly unlikely, unless you are on A12 I recommend you to keep internet disabled and see FRP bypass then knox disable.

P.S-: I'll update few more steps to disable samsung other apps associated to Knox.

Hi there

Thought I’d update my success here. I was able to defeat knox enrollment through TWRP file manager. I was able to mount the system as writeable and deleted the mdm app which solved the problem. The phone can now be used normally

Nice what you did there though you should know now getting back to work environment is impossible.
And Knox is already tripped so root or non-root doesn't make much difference.

    Samsung A7 Lite[LTE] Knox Disable hassle-free​

    Latest SamFw Bypass Tool v4.2 comes with an old method which allows you to disable knox security without resetting the device.​


    This method works partially when knox is disabled without resetting it.

    Following are the instructions:-​

    • Run app with admin privileges (duh)
    • Connect device with PC/Laptop using MTP mode (make sure you have driver installed or you can install drivers from Misc section of the App)
    • Click Disable Knox in Test Mode
    • After pop-up for Emergency Dialer *#0*# or *#*#88#*#*
    • Even if Factory Test Mode fails to run click OK and continue
    • Also if factory mode allow adb manually from settings if that option is available

    App will do most of the work for you your device restarts without reset and you'll get Knox disabled right away​

    Notes:-​

    • This method works even on latest update provided you have dialer access. [ Edit: If no emergency dialer use SIM card with lock on it that should give you a dialer ]
    • Knox might not be disabled completely but most of the restrictions are temporarily disabled till next factory reset.
    • Also Disable samsung bloatware to avoid reinstalling of knox from Galaxy Store. [ Follow thread 2 - 3 below ]
    • You can try this method from setup screen if mtp access is available, as it is highly unlikely to work on latest patched FW. If you don't have Dialer access use FRP BYPASS to reach Dialer App.
    • Also do not think this device is entirely knox free on some level organization control still exist on the device which is limited to monitoring only.
    • Last but not the least make sure to disable Samsung account & OTA updates from ADB menu options.
