Default ROOT lenovo ideatab A21071A-H

hello friends, I ve tried to root my tablet, but I can't do it. the MTK tools doesn't recognize it.
I do activate the USB debugging and installed the MTK tools but it doesn't recognize it. Could you help me please.
Even when I use the "root.bat" file I just get a message which says: "Error Device not found"
Do I have to install CWM first???

did you swich the device in to "media device" insted of "usb storage" ? Device need to be powered on not switched off. And ofcourse you didn't forgot to install "preloader usb driver"?
