Use this guide to replace the dock connector assembly, which includes the dock connector and lower microphone.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Your phone's rear cover may have two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws. Check which screws you have, and ensure you also have the correct screwdriver in order to remove them.

    • Remove the two 3.6 mm Pentalobe or Phillips #000 screws next to the dock connector.

    • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.

So I attempted once to fix the dock connector and failed. A month later I took the phone apart again. The first thing I noticed when taking off the dock connector from the logic board is that it wasn't seated properly. I attached it properly and now the iPhone charges and home button works perfectly!

What about it was not seated properly? any specific contact point? was it not screwed in well if it wasn't seated properly? I just replaced on a friends 4, but it has not turned on yet, and I can't figure it out. It just stopped charging one day so I figured it was a bad port from corrosion or something and replaced it. The swap was easy enough so I'm confused as to why it isn't turning on yet.

Great instructions. Easy to follow. I found that a JIS000 bit worked better than a phillips #00 bit on my Verizon iPhone 4, model A1349.

New part from IFixit works great. Some tips from my installation:

- PH000 screwdriver works well, but takes some finesse. A little pressure to get the screw going, and don't try to over tighten on the way back in. If you happen to round one out, a 00 or 0 PH screwdriver might get enough bite to get it going.

- Plastic pieces are covering the adhesive on numerous parts of the new dock connector. These are to be removed prior to installation.

- Battery does not have to be removed, so I avoided the risk of breaking something else.

I completed this guide, but unfortunately my phone is in no better shape than it was before the dock replacement. Apparently, this was not the problem. The device won't restore in iTunes. It just sits with the Apple logo and an empty status bar on the screen. Now when I unplug it from the computer, I get a black screen, with just a touch of backlight, but no display otherwise. Before the dock replacement, it always said "Connect to iTunes" but would not restore either. Any thoughts on what else I could try now?
