USB update to 8.2

Advanced users may want to see the Clean-install_procedure page

What you need

• 

  a USB flash memory stick which has already the Sugar upgrade files
  where to get it

• 

  an XO laptop

• 

  power charger for the XO laptop

Let's do it! in 3 easy steps

Important

re-flashing your XO will erase everything on it!

(which might be exactly what you want if you are donating your XO, for example)

1) Prepare

• 

  be sure your XO is turned off
  _{what if it doesn't turn off}

• 

  plug your XO to a power source.

• 

  plug the USB stick into any one of the three USB ports.

2) Go

• 

  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.
  
  Let go the power button or the XO will turn off again

• 

  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.
  _{what if I don't get that message}

3) Done

• 

  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

• 

  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 if it doesn't reboot}

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

Where to get a USB with a Sugar update

Make your own

You will need a 512 MB or larger USB memory stick. Some people have reported issues with sticks over 4 Gb.

• No-Fail_Upgrade

Usually works. Includes instructions for updating Activities if you have wireless.

• Clean-install_procedure

Making your own can get messy sometimes, like with U3 and such. This page has all the nitty gritty.
