things are not looking good for your
iPhone it's acting up and shorting out
and it looks like it's time for a new
logic board it's not as scary as it
sounds so today I'm going to walk you
through replacing the logic board in
your iPhone 5s
hi I'm Gwendolyn with iFixit and for
this repair you're going to need an ice
Clack an iphone 5-point pentalobe
screwdriver a phillips double zero
screwdriver a phillips triple zero
screwdriver plastic opening tools a
spudger an iPhone SIM card eject tool a
2.5 millimeter flat head screwdriver and
tweezers I already have the majority of
these tools in my pro tect tool kit so
I'm ready to get started when you do
your repair make sure you follow the
step by step guide on ifixit.com
not only does it walk you through the
complete repair you can also see
comments and notes from other users who
have followed it which can be extremely
helpful first things first I'm going to
make sure that my iPhone is completely
powered off and once I've confirmed that
I'm going to get started by opening the
phone and removing the 2 screws by the
lightning connector with those screws
out I'm going to get started with
opening my phone and to do that I'm
going to use this tool called the ice
black the ice black prize your phone
opened just enough making sure it won't
damage the home button cable that
connects the display assembly to the
lower part of the phone if you don't
have an ice Clack you can use a
combination of a small suction cup in
your spudger to pry the phone open just
be extremely careful not to damage the
home button cable or it's connector
using the ice black is super simple just
position the suction cups right over the
home button open the handles and once
the suction cups are fully engaged
just press the handles together and
you'll have an open phone now we have
the phone open just enough room to
disconnect the home button cable and to
do that we're going to use the pointy
end of our spudger and first pry up the
bracket that's covering the connector
with the bracket cover off we just need
to disconnect the cable but be careful
when you're working with your spudger
that you're only prying the connector up
not prying the entire socket and now
that the home button cable is
disconnected we can open our phone but
keep in mind that the display assembly
is still connected to the logic board to
get it completely off we're going to
need to disconnect all the cables at the
top of the phone but before we can get
to the cables we need to remove the
cable bracket which is screwed in place
by four Phillips screws make sure you
use an organizational tool for keeping
track of your screws they're incredibly
small and can vanish very easily I'm
using one of our magnetic mats which
holds the screws in place and you can
also make notes and keep track of where
the screws come from and there are all
those cables to disconnect them we're
going to use the flat end of our sponger
with the display assembly free we can
move on to our next step disconnecting
the battery even though our phone is
powered down it's a good idea to
completely disconnect any power sources
before continuing any repair the battery
connector is located right below the
battery connector bracket which is held
in place by two Phillips screws
to disconnect the battery we're going to
use the flat end of our spudger to lift
the cable up and out of its socket make
sure you're prying the connector itself
and not the actual socket because you
don't want to break the connector
entirely now we can get to work on
removing the SIM card removing the SIM
card is as simple as inserting the sim
opening tool into the SIM card tray with
the SIM card out we can get to work on
the cables that are connected to the
logic board there are a total of seven
screws holding the logic board in place
and to remove those you're going to need
both a Philips pin and a small flat head
pin using a plastic opening tool gently
pry the logic board up and out of the
phone there is an antenna cable that is
attached to the logic board on the
underside so before you try to pull the
board all the way out roll the board
over and use the flat end of your
spudger to disconnect it
