Yoga 920 bricked after BIOS update

Hi, attempted to upgrade my Yoga 920's BIOS using this BIOS version (link to README):

https://us.download.lenovo.com/consumer/mobiles/5ncn41ww.txt

 

After running the executable, Windows 10 restarted but never came back and the Laptop will not boot. The keyboard and power button flash for about 1 second and then it turns off again. The screen remains off and the same thing happens over and over again until I press and hold the power button for about 8 seconds to completely turn off the system.

 

I tried pressing the "recovery" pin-hole button next to the power button with a papaer clip but the same behavior occurs.

 

I guess it's bricked so I'm wondering if anyone knows of a way to force the Yoga 920 to flash a recovery BIOS or something from a USB stick.

 

Thanks.
