S500wi Firmware updates

Hello -  We've been updating the firmware on some of the older machines that are in our system, and I had one go sideways on me.  I was able to complete the first portion of the update using the Dell Flasher, but then when I powered the machine down and powered it back up, the wireless LAN does not restart and I am unable to turn the DHCP on.

It appears that the machine is bricked, but I'm hoping that's not the case.

Anybody else out there with similar problems ?  I've done about 50 of these updates now and this is the only one that has given me a problem. 

Thanks in advance.
