Download this file:
Put on the root of your sdcard (not in a folder)
Rename to update.zip
Power phone off
Boot into recovery (power phone on while holding down x)
When you see the triangle with the exclamation point, press the volume up key and camera button key (only press the camera key down half way)
Navigate to “apply update.zip” and press the gold center button on the keyboard to select it. It will start the update process
If your installation is 'aborted', it's probably because you named the file update.zip in Windows, which results in a file called update.zip.zip. Try renaming it to just 'update'
