  • Wedge a plastic opening tool into the lower right corner of the Kindle Fire.

  • Pry the case apart and run the plastic opening tool along the perimeter of the Kindle Fire to release the clips securing the case halves to each other.

  • If you are having extreme difficulty inserting the plastic opening tool, carefully use a metal spudger to undo the first clip, then switch back to the opening tool to avoid scratching your case.

    • It is helpful to pry the bottom of the Kindle Fire away (and out from the side) from the top part. Exerting too much force attempting to split the two without pulling away can cause the tabs on the inside to crack.

    • This connector will not be removed until the motherboard is free.

  • Flip open the ambient light sensor ZIF socket with a plastic opening tool.

  • Use a pair of tweezers to pull the blue tab on the ambient light sensor cable to remove it from its socket.

Make sure to mark what ZIF connector goes where, they are not interchangeable even though a first glance the appear to be the same size

It took about 2 hours, but that is, mainly, because reconnecting the ZIF connectors can be overly tedios.

Apparently not all Kindle Fires have the ambient light sensor; This connector is not present on mine.

Stand it up on its end, lining up the holes to the wires. Slide into holes and 'flip'/rotate white plastic piece down into a flat position.

Image 1/3: Lift up on the antenna connector with a plastic opening tool to disconnect it.
  • Use a plastic opening tool to lift up and disconnect the display data cable.

  • Lift up on the antenna connector with a plastic opening tool to disconnect it.

  • De-route the antenna cable.

Be very careful when disconnecting the antenna, and be sure to note how the cable is routed into the little socket on the motherboard. The reconnecting of the antenna cable into its motherboard port can be tricky and will require patience, persistence and perhaps a magnifier and tweezers.

Followed the steps but once reassembled the screen comes on but doesn't respond to touch. It was working fine even with broken glass screen. Any suggestions?

Mine is doing the same thing! What did you do to fix it?

I order a replacement motherboard from ifixit and for some reason it had a plastic increasing around the outer edge of the "display data cable connection port" on the motherboard, which makes it impossible to connect the cable to the motherboard. I called ifixit and they said send a picture and a description. Hopefully the customer who owns the kindle fire will understand that after waiting on the part for a week. :\
