Just looking for someone to point me in the right direction

So I decided to root my phone ...I used the latest Windroid toolkit ..now I was able to unlock the boot loader and install/flash TWRP. here is my issue when I click on the Flash SuperSU button I get this error "wrong device state ! please ensure that your device is in Android! any help on how to finish flashing it would be appreciated.

Windroid toolkit 3.1.0

Thanks:o
