How To Guide Knox Disable on Samsung A7 Lite [Emergency Call/Factory Test Mode]

[Abish4i]

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.

Don't try package pro disabler method even​

that doesn't work due to latest patches​

• After ODIN flash USB debugging was there only for a brief moment [ this got Patched in March 2022 Updates and After]
• I tried using wifi debugging on latest updates with patches using quick tiles toggle from developer options but there too security policies doesn't allow adb connection via server connect [ Noticed how if you don't connect to internet then it works fine ]
• Using local shell with LADB one can disable knox using simple old command. As long as wifi debugging is available and doens't work on PC use split screen and 2 disable commands

pWell, on a non-rooted but knox-triggered device, can the Samsung health app be used if knox is disabled?Well, on a non-rooted but knox-triggered device, can the Samsung health app be used if knox is disabled?

I'm sure it won't though you are free to try. If on A11 then check by disabling knox from Android setup screen.

What about patched builds?

Exynos chip is good but not for qcom

Not working

 

[Abish4i]

@emeran check ADB and MTP connection then say [OR you are on latest patch]

MTB is connected but can't enable ADB, When I type *#0*# I think something prevents it from showing up

 

[Abish4i]

from where setup screen or unable to access via developer options. @emeran

 

[emeran]

@Abish4i Definitely you can't access developer options,

from setup screen

1- open the browser

2- open the phone dialer

3- *#0*# not working " when the code is entered, a screen opens and closed at the same time "

 

[Keshav4]

Works for me only after knox security is triggered developer options can be enabled, @emeran I think you are missing adb drivers or permissions.

 

[Abish4i]

..., a screen opens and closed at the same time "

U should enable adb manually and make sure you have drivers since you device is wifi only.

I have a tablet that has been reset, how do you get to the emergency dialer from the initial setup screen?

xD seriously, it is literally the first screen if you have wifi version than you don't have one then just connect and try without code if it doesn't work try from developer options by manually enabling it.

I've got the LTE version, the first screen just says Welcome, select a language, and Start. I can't get to developer settings because I can't get past the setup because of FRP

What is you FW version?
and
there should be emergency call option right below start button at setup screen.

Ah firmware is latest Android 12. Maybe they removed the option.

 

[Abish4i]

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.

Will this work with a Canadian version S20 Plus?
