create-user "Error: couldn't create User" I tried creating multiple users on my Android TV dongle (based on RK3188 board). It should work, it's Android 4.4.2, but it returns an error:

root@rk3188:/ # pm create-user username
Error: couldn't create User.


And at the same time:

root@rk3188:/ # getprop fw.max_users
4
root@rk3188:/ # pm get-max-users
Maximum supported users: 1
You should edit your build.prop and add the following lines:

fw.max_users=2 #in case you want a maximum of 2 users

fw.show_multiuserui=1 # to show Users menu in settings

Save and reboot. You will then be able to add users
