flashing rom – Nexus 10 starts in fastboot, but not in anything else

I'm stuck with what looks like a dead Nexus 10 or a stupid problem.

If the device is off – And I hit flight + flight- and pwr – He enters fastboot. After that, no joy. I get a black screen if I try to start (no Google logo, even). I receive a black screen when I try to recover. I just can not go beyond fastboot.

Things I've tried:

  1. Disconnect / Reconnect the battery
  2. Cleared cache
  3. Finally flash-all with Manta Image (successful)

After all this, it goes directly to the black screen. Something is screwed royally, or I miss something flagrant. Suggestions?
