[Question] W716S 4.4.2 - Root and Flash a Recovery

[naced]

Hi everybody,

I have a W716S (It's exactly the same specs that the W716 but with a flash Led) base on a MT6572 (MTK6572M)
I flashed it to have KitKat, with an official rom : Haier_W716S_W727D_FR_M00_S001_140910 , by SP Flash Tool by using the scatter file find in the rom.
Now I'm on 4.4.2 with the Kernel 3.4.67 and I want to install a custom recovery and root it

About the root:
Framaroot worked when I was in 4.2.2 but not now.
I tried Framaroot, towelroot, vroot/iroot, KingRoot, rootmaster... etc etc Nothing Work

So I had think to Flash a recovery and after install SuperSu by a Zip.
But I don't understand how to find and custom the boot.img and recovery.img to have CWM or TWRP

Any one can help me ?
Thanks a lot ! in advance
(sorry for my english i'm french)
