if you're having trouble syncing or
charging your iPhone for the culprit
might be the phone's dock connector
fortunately replacing the dock connector
is not that big of a deal
hi I'm MJ with iFixit and today I'm
going to show you how to replace the
dock connector in an iPhone 4
this video is a great overview of the
process but of course when you're doing
your repair you'll want to follow the
step-by-step instructions and the repair
guide on our site just so you know the
phone that I'm working on is the GSM
version of the iPhone 4 if yours is a
CDMA version the repair is really
similar but there are some subtle
differences but if you're following the
repair guide you shouldn't have any
problems that all being said I'm going
to get started with my repair by getting
all my parts and tools together for this
repair you're going to need one of our
new 54 piece bit driver kits that way
you have all the bits you'll need during
the repair including the coveted
pentalobe driver a plastic opening tool
or a plastic spudger a sim ejection tool
a pair of tweezers which I got from our
precision tweezer set a screw tray to
keep track of all those teeny tiny
screws you're going to be removing from
your phone and anti-static wrist strap
to protect your device from any
electrostatic discharge during your
repair and of course a replacement dock
connector now that I've got all of my
parts and tools together I can get
started and the first thing I'm going to
do is make sure that my phone is powered
off and once I verify that it's off I
can really begin by removing the two
pentalobe screws at the bottom of the
iPhone
once those screws are out the rear panel
slides up really easily and then lifts
right off the phone and the very next
step is to take out that battery and
it's only being held in place by a screw
and a cable so I'll go ahead and take
care of those now
the battery is held in place by some
pretty strong adhesive so you're going
to use your plastic opening tool and
gently begin to pry it up once it's
mostly pried up you can start to use
this pull tab to get it out the rest of
the way now that the battery is out the
next big piece for us to take care of is
the speaker enclosure assembly in order
to remove it we've got to disconnect two
cables that are connected to it
this larger cables held in place by a
lot of adhesive so you want to use your
plastic opening tool just like you did
with the battery to kind of gently pry
it up
now that I've got the speaker assembly
removed I can get to work on the dock
connector first things first I'm going
to disconnect the home button cable and
you want to be kind of careful because
it's really fragile
once I've flipped up the tab on the ZIF
connector I like to use my tweezers to
really gently pull the home button
ribbon cable out of its socket it helps
for me if i anchor both of my hands on
the table the way don't end up pulling
too hard and ripping the cable once that
cable is disconnected you're going to
use your plastic opening tool to really
gently pull the microphone holder out of
its little tube now there's only two
screws and some adhesive holding the
dock connector in place and once those
screws are removed I can begin to pry it
up with my plastic opening tool after
some gentle prying I was able to remove
my old dock connector and now all I have
to do is reinstall my new one of course
