Half way through flash firewall stopped it

I just tried to flash my Sirocco to the Vista firmware version and about half way through the windows firewall warning popped up, pausing the transfer. I allowed the transfer to continue but it was too late. I have a bricked Sirocco. The vista driver can't see the device and it has lost the wifi signal. I tried doing the reset to flash it again, but the embedded ip does not work now. What can I do to fix this or is it a doorstop now?
