Introduction

Use this guide to replace the motherboard 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.

Same here. Ridiculous!

I can confirm that the camera does fit very snugly into back cover.

Start by prying off the cover from the end opposite the camera. When you get near the camera lens, press the lens gently into the body as you continue to release the cover.

Use a spudger to disconnect the front-facing camera ZIF connector.

  • Use a pair of tweezers to gently lift the front-facing camera up from the motherboard.

Use spudger to flip white part of connector forward (towards camera). Then use tweezers to pull camera upwards and towards edge of case. It will slide right out.

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.

On mine, the copper shield is smaller then shown in this picture. It does not cover the battery connector, hence you don't need to remove the copper shield to remove the battery.

Ditto. My theory is that ours were later model Nexus 9s produced after this ifixit featured this product!

Sur certains modèles, la feuille de cuivre est sous la batterie et n'a pas besoin d'être enlevé.

Using the spudger tool, carefully remove the bottom of the battery from it's location below the logic boards.

  • The battery is attached to the motherboard with some adhesive, so you may need an iOpener to loosen up the adhesive. Check out the iOpener guide for info on how to do it.

  • Do not pull the battery from the tablet yet, as it is still connected to the motherboard.

On my tablet, it was not glue, but double stick tape along the both long sides. I used the iOpener, which I laid along the sides. (My iOpener had printed on it, “Wait 10 minutes before reheating again.”) I slowly peeled the tape off of the battery. The copper shielding was below the battery. I carefully peeled the tape up in hopes of reusing it.

On mine, the battery was held by two strips of double stick tape. My iOpener helped. (my iOpener had written on it, “Wait 10 minutes before reheating again. ) As I lifted the battery, I peeled the tape away from it. Then I peeled up the tape in hopes of reusing it.

Now remove the metal clip covering the battery's connector cable located above the top left of the battery with the spudger.
  • Now remove the metal clip covering the battery's connector cable located above the top left of the battery with the spudger.

  • After the metal clip is wiggled free, the battery's connector cable can be easily removed by just gently tugging it free.

Use spudger to apply light pressure to right (as seen in picture above) side of clip near the board. Right side of clip will spring left and up. Use tweezers to lift clip upwards and to the right. It will come right out.

White battery connector lifts straight up to disconnect.

The battery should now lift free of the tablet.

Again, on my Nexus 9, were I trying to actually remove the battery, it is double side taped to the frame. The battery’s casing would be further torn to shreds, should I try to remove it.

Good thing I’m just trying out a XDA repair for the “white/pixellated screen-150 decibel scream issue” that seems to be plaguing N9s nowadays, which involves cleaning the battery contacts. I may just have to replace it now, should it’s performance get any worse.

(It’s almost as if HTC wants the battery to be seriously damaged if replacement is attempted.)

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

Unscrew the three 3 mm Torx T5 screws on the antenna board.

    • 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.

  • Remove the three 3 mm T5 Torx screws.

  • Remove the five 2 mm Phillips #000 screws.

For the Phillips screws, I found Phillips #00 to be a better fit.

In mine, the mother board exended all the way to the right. Two of the phillips screws held the SIM slot daughter board and connected to the motherboard with a ZIF connector. Next the the SIM board was a white antenna cable.

Using your fingers, pull up on ribbon connector to expose another ribbon connector below. Remove the two 2 mm Phillips #000 screws on top of the second ribbon connector.
  • Using your fingers, pull up on ribbon connector to expose another ribbon connector below.

  • Remove the two 2 mm Phillips #000 screws on top of the second ribbon connector.

  • Pull up the ribbon connector with your fingers.

The top ribbon cable goes to the (now) right daughter board and the ZIF connectors were already opened. The bottom ribbon cable is connected kind of underneath the second daughter board. This is a ZIF connector and one would lift the black (on mine) part that would be away from the disassembler.

I also had to remove the volume up/down rocker that was attached to the old motherboard with a connector and an adhesive strip. Remove this and transfer to the new motherboard before beginning to install the new motherboard.

On mine, the copper shielding was still attached. I wish I had left it attached. I slide a spludger from the right to get the board up.

Refer to the rear-facing camera replacement guide to remove the rear-facing camera from the motherboard and transfer it to the new one.

I don't understand by what it means transfer it to the new one? I only want to replace the display and LCD.

It is not necessary to remove the battery, just disconnect it. And you don't need to take all the copper off, just take it back to the battery.
