Introduction

This guide demonstrates how to remove and install a headphone input for the Kindle Fire HD 8.9".

Remove the SIM card tray (if present in your model). Insert a large plastic opening tool next to the Kindle's headphone jack. Make sure the notch on the plastic opening tool is facing the back of the Kindle.
  • Remove the SIM card tray (if present in your model).

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

    • Make sure the notch on the plastic opening tool is facing the back of the Kindle.

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

  • Be careful not to completely separate the rear cover. There are two delicate flex cables that connect the display assembly to the motherboard.

Getting the SIM card dummy plug out a real challenge. Broke off one end. Seems this part was never intended to be removed.

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

  • These images show the Kindle laying flat. In order to prevent damage to the flex cables, keep the Kindle open at 90 degrees while disconnecting the display assembly.

Lift the retaining flap on the ZIF connector of the upper flex cable. Gently pull the cable out of its socket. This  flex cable is delicate. Be careful not to crease or bend it while working.

This is very delicate. The flap is very easy to break off. Remove the yellow tape on both these connectors and replace with ordinary plastic tape upon reassembly. If you don't tape them you'll pull them apart working on the other. A helper to hold the assy is a good idea.

Gently grab the metal casing that covers the headphone input, being careful not to force or break anything, and lift upward. This metal casing also holds in the power and volume buttons. Be careful not to lose the buttons while working with the headphone input.

This guide was quite useful - until I came across it I had no idea it was feasible to replace the audio jack! There were a couple of areas where the instructions could be improved, namely:

* Overall - the description of "Easy" must be relative. Once you've done it once it might be easy, but although I've many years of experience tearing apart computers, as a newbie to opening a tablet device I found it quite tricky. Next time it may feel easy, but that is misleading for a newbie.

* Step 1

** On my device it took a LOT of force both to get the tool inserted and at various locations as I slide it along each side. Also, going around each corner to a new side was also tricky.

** Unsure what "Make sure to remove the lock key" meant. What "lock key"?

** Although there is no true hinge, the two ribbon cables imply one should treat the device as if hinged along the conventional "bottom" (where the USB and HDMI ports are).

* Steps 3 & 4 - It would help to mention that each connector has a movable locking mechanism and that the "black" item referred to is the movable part. Also that it is secured with yellowish transparent tape that must be pulled off prior to unlocking. Unlocking consists of flipping the black plastic piece up 90 to 180 degrees and locking is the inverse operation. Lastly you cannot get your finger under the black piece, but your fingernail might work. I was initially very confused, the only black thing I could get my finger under was the ribbon cable. I did in fact manage to pull the cable loose before realizing I should have removed the yellow tape and unlocked the connector.

* Step 7 - I'm not sure why the 3rd screw is mentioned. I did NOT need to unscrew it.

Hope this comment clarifies things for the next person (and thanks to the original author).

This was super easy. Instructions are well written and easy to follow. I purchased a new Kindle before I found the instructions. In the future, I will check here before buying anything new.
