Introduction

Replace the vibrator daughterboard in your Nexus 9. It connects the motherboard to the lower speaker, vibrator, and a 3-axis compass. The photos in this guide show the battery removed, but it is not necessary to remove the battery to get to the daughterboard.

Parts

No parts required.

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.

Unscrew the two 3mm T5 Torx screws securing the daughterboard to the device. Use a pair of tweezers to disconnect the vibrator cable. It will lift straight up from the daughterboard connector. Use your fingers to lift the daughterboard upward and out of the device.
