unlocked bootloader, kingroot says it's rooted, no root apps works

I have used the naked drivers to unlock the bootloader, and then used the newest king root apk to root it, but it says it's already rooted, so i downloaded supersu and foldermount, but supersu says there ain't no su binary installed, and foldermount is stuck on refreshing "checking for root" constantly.

Have i done something wrong here?
