and the volume control cable in the
iPhone 4 remember this is just an
overview so be sure to check out our
step-by-step guides when you do your
repair and if you're working on a
verizon phone your repairs can be
slightly different so make sure you're
looking at the right guide for the right
device you're working on for this repair
you're going to need an iphone 5-point
pentalobe screw driver if your iPhone
has external pentalobe screws or a
Philips triple zero screw driver if your
iPhone has external Phillips screws a
sim eject tool or you can use a
paperclip
a Phillips double zero screwdriver
plastic opening tools 2.5 millimeter
flat head screwdriver spudger and
tweezers I have all the parts and tools
I need in my pro tect tool kit and it's
not listed on the repair guide but I
never do a repair without my magnetic
mac again it's magnetic so none of those
little parts will roll away and it keeps
me organized so let's get started first
make sure your phone is turned off
and then you're gonna remove the two
screws at the bottom near the dock
connector okay with those screws out now
we're gonna take off the back panel and
to do that you're just gonna push with
both thumbs up and it should come apart
like that and then we can just take it
off now we can get the battery off and
to do that we're just going to get our
Phillips driver and unscrew the one
screw that's holding on the battery
connector
now we can use our opening tool to pry
off the battery connector and while
you're down there remove the content
clip now we can use this tab to get the
battery out and if you're having a
little trouble you can use your opening
tool now we can take out the SIM card
and to do that we're going to use our
little sim ejector tool and we're gonna
poke that in the hole right here on the
side and it pops right out now we can
remove the two Phillips screws that are
holding on the dock connector bracket
now that we have those screws off we can
take the bracket off with our fingers
and then we can disconnect that cable
from the logic board with your opening
tool with that unstuck we're going to
use the pointy end of our spudger to
disconnect the antenna cable right here
now we can remove six screws that are
holding the logic board to the rear case
there's one at the bottom and there are
five at the top and with those screws
out now we can take off the bracket with
our fingers and get to work on the
rear-facing camera and to do that I'm
just going to use my spudger we're gonna
pry up that cable and set it aside now
that the cameras out we have one screw
in the middle of the logic board that's
near the pull tab for the battery if
there's a sticker covering it go ahead
and take that off first and then get to
work removing the screw now we can use
the flat end of our spudger to
disconnect the five cables at the top of
the board
now that all those cables are
disconnected we can attack the last
standoff screw with our flat-head
screwdriver
and that is the last screw now we can
get our logic board out but be sure that
you're not going to tear any of these
cables that we disconnected earlier and
on reassembly make sure this tiny
antenna at the bottom is not underneath
the logic board now that we have the
logic board out we can take out the
front-facing camera but it is held in
place with a bracket so we're gonna use
our spudger to pry that off and there's
the bracket and now we can get to the
front-facing camera now we have two
screws holding on the vibrator so let's
remove those and take the vibrator out
and now that that's out we can use our
spudger to remove the piece of black
tape that is covering the volume button
bracket and while you're down there
remove the five Phillips screws securing
the silent and volume brackets to the
outer case and now we can use a pair of
tweezers to get the silent switch
bracket off but don't take the silent
switch out of the phone just yet
and now we can move on to the headphone
jack assembly we're gonna use our
tweezers and you're gonna pull gently
but make sure not to pull too hard and
to be careful of all those cables
because you don't want them to tear and
now all you have to do is transfer the
old brackets to your new unit and work
backwards on the step-by-step guide to
