ADB USB debugging not working with NVIDIA Shield TV (2017) firmware 6.0

So I’m not sure if it’s related to the new firmware, but USB ADB debugging used to work just fine with this Shield and the same USB cable and same Windows PC, back on 4.0 firmware I think.

Here is what I’ve tried:

  1. Enable developer options
  2. Enable USB debugging (and revoke authorizations)
  3. Plugged USB cable into slot furthest from the HDMI port
  4. Tried to update the drivers with

These are the errors I’m seeing in Windows 10:

  1. “USB device not recognized”
  2. “The last USB device you connected to this computer malfunctioned and Windows does not recognize it”
  3. In the Device Manager I see a “USB composite device” with a yellow triangle but I can’t update the driver with the one I downloaded above. These are the detailed errors:

This device cannot start. (Code 10)

OREO Problems…

updated firmware using fastboot via a usb cable…

worked fine and i kept my apps but lost root and the mod that made my Mele remote work.

flashed the dev version of the same ROM

it failed during the system.img flash…

Now the box is bricked and it is not recognised as a USB device so i can’t unbrick.

The recovery and boot .img’s flashed fine but i can’t get in to recovery by pressing A+B.

So i’m basically i’m fu**ed.
(all for a poxy home screen revamp)
