Default Can't Find version number on bricked HTC Flyer

So I recently bricked my HTC Flyer and the few forums that I could find on how to un-brick the device call for an RUU. After searching I just can't seem to figure out which RUU to obtain, and when I try to find the version number on the flyer by using:
fastboot getvar version-main
I get nothing. Is there any way to get the version number or where I could find an RUU for my device?
