Shaky Hands != Fun With Small Connectors
My sister accidentally dropped her Macbook Pro Retina after owning for more than 4 years. The warranty had expired a long time ago and the people at the Mac store gave an estimate of at least $700. When my family told me about this, I told them that was ridiculous and to order a new display from ifixit.com so that I could fix it myself.
The disassembly was a smooth process overall. The little rubber wedges covering the screws that keep the display attached had their adhesiveness stripped in the process of removal so there was no way to put those back on during reassembly.
During reassembly, the most challenging part by far was getting the three antennae cables reconnected. This part alone took me about thirty minutes of constantly trying. My hands slightly shake and when you are dealing with connectors that small it is very frustrating.
The way I was able to get the three antennae cables connected was to bend the wires just enough so that the wire remained flat with both connectors matching up exactly. This makes it much easier to connect as all you have to do is repeatedly press with the spudger until it "clicks".
