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 connection has issues

• Try 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
