Kindle Fire HD 8.9" Battery Replacement

Insert a large plastic opening tool next to the Kindle's headphone jack.

Move the plastic opening tool evenly around the Kindle, separating the two halves.

Set the Kindle down on the rear case.

Holding the display assembly near the camera, carefully open the display assembly up to about 90 degrees from the rear case.

Lift the retaining flap on the ZIF connector of the upper flex cable.

Gently pull the cable out of its socket.

Separate the display assembly from the rest of the device.

Remove the following sixteen screws from the metal midframe on the rear of the device:

Four 3 mm Phillips screw (located in each corner of the device - noted in red in the diagram)

Four 3 mm Phillips screws (surrounding the ports - noted in orange in the diagram)

Eight 3 mm Phillips screws (located around the body of the midframe - noted in yellow in the diagram)

Carefully remove the metal midframe.

Lift up on the silver ends of the black flex cable that lays across the battery.

Gently pull the black flex cable from the battery.

Disconnect the orange button cable from its socket on the motherboard.

Starting at the outside edge of the battery, use the flat edge of a spudger to separate the battery from the rear of the device.

Move the spudger along each side of the battery, prying upwards with even pressure.

As the adhesive releases, push the spudger further underneath the battery.

Once half of the battery is detached, pry the other half in the same manner.

Remove the battery assembly from the Kindle.
