Introduction

Use this guide to replace the antenna board on your Nexus 9.

With your fingers, carefully pry off the back plastic casing. Starting at the corners is usually the easiest. The rear-facing camera seems to fit a little too snugly in its compartment on the rear case; so make sure that it stays connected to the motherboard.

Just removed the cover. On mine, there is a piece of double sided tape, 2"x1", bottom middle, sticking the back cover to the battery. The battery pack's black skin ripped as I pulled the cover off. I was able to peel the skin from the tape and reposition on the batteries. Don't think this black skin is nothing more then a way to print branding and other texts onto the batteries.

This step is not necessary if you have already removed the battery. Carefully peel up the copper shielding with your fingers.

  • Before fully removing the copper shielding, make sure that the blue antenna cable is out of the way of the copper tab.

    • When reinstalling the antenna, be sure to clean it with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.

  • The antenna board should now lift free of the motherboard.
