if anyone just need to bypass the lock code screen when it shows (using sftp client) i found that this works for me: dbus-send --system --type=method_call --dest=com.nokia.system_ui /com/nokia/system_ui/request com.nokia.system_ui.request.devlock_close string:"com.nokia.mce" string:"/com/nokia/mce/request" string:"com.nokia.mce.request" string:"devlock_callback" uint32:'0'
