Step 1: Tools and Supplies
1. The damaged dock in question
2. A leftover wire (I used a cat 5 patch cable)
3. A wire cutter (I used the cutter on my leatherman)
4. An x-acto knife
6. A surface that you can cut and glue on (that isn't your expensive laptop that you just bought three months ago like I nearly started doing)
Step 2: Use the Glue
Place the dock aside and let it cure while you move on to the next step.
Step 3: Prepare the Wire
After cutting it open, remove the contents and save for another project if you like. After that, cut a segment of the wire sheath long enough to cover the crack in the dock and overlap on both sides. Mine was 3/4 of a centimeter, but you could do it longer as well.
Step 4: Paste It On
Apply a dab of superglue to the crack again, over the already dried glue and spread it all the way around the crack.
Now press on the wire sheath/patch over the glue. Hold it in place over the glue for at least a minute. Make sure you press it until you see glue coming out from the sides of the patch. Make sure you don't accidentally glue your fingers to the dock.
After that, put a dab of glue on over the patch, completely covering it, adding a bit more strength to it.
Leave it overnight in a cool, dry place to let the glue cure completely.
Step 5: Enjoy Your Repaired Dock
As such, you shouldn't press on that tab anymore, because that twisting stress on that plastic bar is what caused it to fail in the first place.
From now on you should pop your phone in and out in this fashion
