How to do it exactly...

First Method using ADB/Terminal Emulator​

1) you need to flash stock rom from here N7100 Note 2 4.3 Leak MI6 Download

2) then root it from dr.ketan's thread Here

3) set up google account and download android terminal emulator (totally free) from here :

Android Terminal Emulator

4) write down this without any brackets...

5) now go to setting and see users will be enabled in """more""" tab (((((((( Settings>>more>>users>> ))))))

6) then you'll be switched to that account and start again setting up whole phone as it was when flashed stock..

7) voila you have multi user restricted.

8) no knox on secondary users... happy :D :D

9) Reboot takes you to admin accont.

you can also manage profile with ""TASKER"" or any other app specailly like profile switchers if any not seen you can contribute.. or script

::::::::::::: Update:::::::::::::

::::::::::::: Switch Multi user from lockscreen:::::::::::::​

Es File Explorer and create a new file and name it "users.sh". Edit it with a text editor and type

[SIZE="6"]#!system/bin/sh
setprop fw.max_users 5
[/SIZE]

Save after this of course as "users.sh"

then go to terminal emulator and type

[SIZE="6"]su
chmod 755 /storage/emulated/0/users.sh[/SIZE]

Assuming the path to "users.sh" is " /storage/emulated/0/users.sh"

Next, open Script Manager and click Browse as root.

Navigate to "users.sh" through the Script manager.

Once "users.sh" is found, click on it. Then make sure "is script" is ticked and the icon for superuser and run at boot are lit up.

GO ahead and hit save and you should be done.

All this is assuming you already have at least one more user other than primary already setup.

This will set the Users tab in settings to come up everytime your phone boots up.

REMEMBER TO SWITCH USERS ON 4.2 YOU MUST HAVE Auto-ROTATE ENABLED AND ROTATE YOUR LOCKSCREEN TO LANDSCAPE

or use this app..

4.2 multiple user enabler root

everytime run it after reboot wont take time but you ll get what u want in settings and lockscreen.
