well friends, its my first post here on xda.
Eventually I found the easiest way to root D5322 (.472 lollipop 5.0.2 firmware)
and
that is
just run kingroot (I tried english version)
kinguser works like a charm
no need to have superuser or superSU
every app that requires root, works as smooth as butter
like busybox force2SD and all.
I attached the english version of kingroot with this post

those who had rooted their (.470) phone with kingroot and repented later , can also try..
well..
.
.
and if you want to get rid of kinguser that had gotten installed after rooting with kingroot
here is a trick..
I am attaching a zip (thanks to
@edwuard )
download that zip
put it in internal memory
extarct that zip in internal memory
now you will get a folder named mrw in your internal memory
..
..
install terminal emulator from market
write the following commands
su
(now grant superuser access)
$ will change in to #
now write the second command
sh /sdcard/mrw/root.sh
(there is space after sh . You can copy this command from here and paste to terminal emulator)
after some sequences in terminal emulator..it will launch SuperSU
and ofcourse remove kinguser
update the binary of superSU
verify root with root checker
.
.
that's it !!
