we're gonna go over replacing the power
and lock button in your iPhone 4 hey

I'm going to walk you through replacing
the power/lock button in your iPhone 4
remember this video is just an overview
so be sure to check out our step-by-step
guides when you do your repair also if
you're gonna work on a verizon phone the
repair is slightly different so be sure
to check out the right guide for the
right phone for this repair you're going
to need an iphone 5-point pentalobe
screwdriver if your iPhone has external
pentalobe screws or a phillips triple 0
screwdriver 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 map 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 powered off but as your
power button is broken you're gonna have
to wait until it dies and then you're
going to get the two screws at the
bottom by the dock connector outs so
that we can open the phone
[Music]
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
contact 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
open 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 gonna 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 stand off screw with our flat
head screwdriver and that is the last
screw now we can get our logic for now
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 going to use our spudger to pry
that off
and there's the bracket and now we can
get to the front-facing camera now we
can turn our attention to the two screws
that are holding on the power and lock
button bracket if your cable is the
problem you can check out the power and
sensor cable guide and pick up at step
25 I'll go over those steps right now
start by pulling the bracket out of the
outer case you can use your tweezers to
pull the headphone jack out then you can
use your plastic opening tool to get the
earpiece speaker out of the case now you
can remove the cable and transfer the
power bracket to the new cable if you're
only replacing the button let's move on
to the last couple of steps now we can
use our fingers to remove the bracket
and then we're going to use our tweezers
to remove the button and there it is now
you can replace this with your new power
and lock button and work backwards on
