'Secure reflash' is a mechanism for restoring an OLPC with unmodified firmware to factory defaults.

To perform a secure reflash, prepare a large USB key (>=512 MB recommended) by

  1. Formatting it with the FAT file system.
  2. Downloading two files - 'fs.zip' and 'osNNN.img' from the official images site
  3. Storing these two files, e.g. 'fs.zip' and 'os653.img' in the root (top-level directory) of the USB key
  4. Unmounting the USB key and, when safe, detaching it from your main computer and reattaching it to the XO
  5. Rebooting the XO and, as it begins to boot up, holding down all four right-hand-side game-pad keys
