USB update to 8.2

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
