In this tutorial, we learn how to take apart the Google Nexus One. First, take the battery cover off, then remove all the screws along the side and top of the phone on the back. Next, use an opening tool to pry the case off of the back. Then, pry the bottom cover off and then remove the two T5 screws underneath that. After this, take the casing tool off of the back and then remove all the Philips screws. Now, remove the three flex connections and the cable connected and set them aside. Pry the top board off to unclip it, then remove the volume button. Free the assembly, then remove the main board and you'll be finished.
