The NVIDIA SHIELD TV is a production Android device, and hence I'm 
pretty sure it has boot security enabled. This security also applies to 
the USB recovery mode protocol, so I don't believe you'll be able to 
communicate with the device unless you know the system's keys, which I 
assume you don't.

There is some support for flashing generic upstream Linux onto the 
NVIDIA SHIELD tablet, but I believe that relies on  making (at least 
some of) the modifications from a running system, so if your system 
isn't booting, I don't expect this will work either. Just in case it's 
useful, see:
