  1. Download the Android 2.2.1 firmware for the Nexus One from here
  2. Rename the file update.zip and copy it to your microSD card via USB. [Note: make sure the file is named update.zip and not update.zip.zip.]
  3. Power down your Nexus One
  4. Hold down the "Volume Down" button as you power the phone back on.
