I am curious if there is a possibility to recover a wrongly flashed NVIDIA SHIELD TV device by flashing u-boot instead of cboot and mounting the emmc in uboot to do some repairs.
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:
