You need

Do it!

Prepare

  • be sure your XO is turned off
  • plug your XO to a power source.
  • plug the USB stick into any one of the three USB ports.

Start

  • hold down all four gamepad keys (on the right side of the screen, above the power button).
be sure to get all four.
  • while still holding the four gamepad keys, push the power button to turn the XO on.
You may need your other hand to do this.
  • keep holding down the four gamepad keys until the message "Release the game key to continue" appears on the screen.
This will happen fairly quickly, a couple seconds at most.

Go

  • Release the gamepad keys. If you see a grid of black and other colored boxes on your screen, congratulations! Your XO is reflashing.
  • Just sit back and let it do its thing.
It will take about 10 minutes

Done

  • your XO will automatically reboot when it is done.
Your XO may reboot twice, playing the little XO tune both times.
  • it will reboot automatically and ask you for a name, as if it were brand new.

What can go wrong

The XO does not turn off

  • In extreme cases of software failure you may need to remove the power source and the battery if any light keeps flashing in your XO.

===No "Release the game key" message

possibly you didn't get all the game keys at once
  • power off again
  • go back to Start
possibly the USB flash memory is bad
  • Try again, maybe plugging in the flash memory to another XO port
If after trying several times this doesn't work, suspect the USB flash is bad
  • replace

No grid

If you got the "Release game key" message, but no grid after a couple minutes,
  • try another USB port. If still no go, suspect the USB flash - replace

No reboot

If you got the "Release game key" message, then the grid, but no reboot,
  • remove the flash memory, reboot manually
  • If no result after a couple minutes, try again from the start with another USB port.  ;If still no go, suspect the USB flash
  • replace
