You now have to perform this task: boot the Nexus 10 in Bootloader Mode; a good way to do that would be to press + hold Volume Up + Power at the same time, then stop as soon as you see Fastboot Menu along with “Start”.
  3. Now make sure you wait for some guidelines to settle on the display so that you can follow them. When you’re done, we ask that you do this: press, a couple of times, the key called Volume Up.
