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.

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.

note that the image still displays the speakers that were supposed to be removed in an earlier step

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. :\

Mine no longer responded to touch!!!!! Why did we all have the same problem on reassembly after changing charging port?
