I'm trying to OTA upgrade a Nexus 9 tablet running 5.0.1 to Nougat. I download the update, verify, and tell it to install. After a little bit, I get the "dead robot" screen that says "Error".

I did a factory reset, downloaded the update again, ran it again, and got the dead robot again.

I've been googling, but I can't find anything offhand that explains what might be happening.

Is there any way I can debug or diagnose the problem?

  • Rooted? System modified? It shouldn't error out if not. – Andy Yan Sep 8 '16 at 3:55
  • @AndyYan: Not that I know of. It's a work tablet that we've done very little to. – abeger Sep 8 '16 at 14:43

Well if you've already done a factory reset then I assume there's no precious data to be backed up on the device - in that case just grab a factory image, install appropriate drivers and flash manually. The one for the WiFi variant is already out.

  • Yeah, that's basically what I ended up doing: Side-loading 7.0 from my laptop. – abeger Sep 9 '16 at 1:50
