To Upgrade from a USB stick

First you need to create a USB stick with the latest stable build:

1. Go to the jffs2 download page for stable build, http://download.laptop.org/xo-1/os/official/
2. Download two files to your local computer: fs.zip (about 200k), and osXXX.img (about 300M); where XXX is the build number.
3. Put these two files on the USB stick at the root directory. Remove any other files on the USB stick.

Next, upgrade your laptop:

1. Ensure you have both a power adapter and a battery plugged into the laptop.
2. Insert the USB stick into the laptop while it is powered off.
3. Press the Power button and it will start the update process, first by backing up your files.
   • If you wish to remove all data and get a clean install, hold down all four gamekeys right after pushing the power button.

To see the version of code your laptop is running:

1. Boot the laptop; and wait until you get the sugar home screen.
2. Hold down Alt, Ctrl, and 'mesh' (the third key from the left along the top row).
3. Check the version by reading the label just above the login: OLPC Build 649 (match that against expected build number).
4. Hold down Alt, Ctrl, and 'home' (the 5th key from the left on the top row) to get back to Sugar UI.
