Help needed asap

So guys i got my htc one m9 yesterday. its T mobile variant. But i guess its unlocked. I am using it here in India. The problem was that it was still on android 5.0. so today i tried to update it to marshmallow through RUU.exe since it wasnt showing OTA update. Just after one min of the setup, it failed, and the phone is now stuck here. Please tell how do i get it back. Thanks. ( i am not being able to upload the snap of the screen)
