Moto360 Root failed, boot-looped

Hi, I'm a newbie. I can't reply the post at there so I post my question here.
I'm using the Super tool for Moto 360 root.

But I stuck at boot looping while I flash the SuperSU zip into Moto360
Just same as Psycho_666 question.

Does anyone has the same experience?
