[Shield Android TV Q&A, Help & Troubleshooting] macche80:
Hi, I have a shield Tv 2015, 16gb version. Few weeks after the upgrade at 8.2, the shield stopped working with a black screen. I unplugged the power, and from that point on, it's stuck in the 4 rolling circles boot logo (before composing the android word).

I went into fastboot and I tried to flash the image using the instructions here:

https://xdaforums.com/shield-tv/general/guide-how-to-flash-recovery-image-t3321404

I took the NVIDIA SHIELD ANDROID TV 2015 Recovery OS Image (8.2.0).

Everything seems worked fine, at least as far as fastboot was telling me, but after I rebooted, it was same as before, still stuck on the boot logo, like if I have not flashed anything.

Any advice on how to proceed? Is it bricked and there is nothing to do?

Here is the log from the flashing:
