Zeus flash device

Hi all just a question . HTC m7ul s-on tried to restore device to stock with a help of xda guide ...but now I get to bootloader and can move with volume up-dowm button but power button won't select anything ...power button works to power on device but just sits on a white htc screen for a minute then screen goes off ....when connect to laptop the laptop see the phone as a ZEUS FLASH DEVICE

Is my phone dead or can I revive it

Thanks
