warning this video is for reference and

education purposes only by undergoing

this repair you assume full liability

for your device neither I rescue nor

that snazzy iphone guy Oh to be held

accountable for any damage that may

occur during the self installation

process you are performing this repair

at your own risk the first step is to

remove the SIM card from the phone

itself by using the sim ejector tool or

a paper clip remove it from the side of

the device you will then want to power

down the device do so by holding the

power switch and powering off if you are

unable to access the LCD screen as I was

you can hold the top button and the home

button simultaneously for about seven to

eight seconds

now on the bottom there are two screws

and those will need to be removed and

set off to the side be sure to keep

track of them we don't want to lose them

you're not going to take the back cover

and simply slide it up it will then be

able to be pulled directly off from the

device now it's time to remove the

battery from the compartment you can do

this by unscrewing the screw which is

attaching the connector to the


once you've unscrewed a place it in a

safe location that differs from the

screws that you just unscrewed try to

keep them staggered and separate so that

it won't be as difficult to put them

back together you will now be able to

remove the connector from the

motherboard you can do so by using a

screw driver or a case opener tool it is

a little bit difficult but don't worry

it's a little bit resilient there's not

a very high chance that you're going to

break it so don't be worried by popping

that off you will now notice that

there's a little bit of a metal wedge

you'll need to pull that out and place

that off with your screws we'll put that

in back later now you're going to need

to remove the battery itself it is glued

in there so it may take several trial

and error attempts don't be worried if

it doesn't come out the first time it

will take a little bit of working and

nagging and you should damage any of the

internals just be a little bit careful

you're now going to need to remove a

plate that is on the side of the device

this plate is covering a connector and

this connector attaches both the dock

connector and the microphone to the

motherboard so you're going to need to

unscrew this there's two screws there's

a larger one on the right and a smaller

one on the left

don't be too worried about keeping them

separate but you will want to note that

when we reassemble it just place them in

their own selective corner on your table

where you're keeping your screws you can

now pull the plate off once both screws

have been removed and place that with

the screws that you have just removed

also once you have removed this plate

you will need to remove another plate

which is on the top of the device there

are five screws that need to be removed

at the very top of the device aka the

teal one you will notice that it is

significantly longer than the other four

screws however there are four different

varieties of screws and only the orange

ones are the same so please put them all

together as we will need to put them

into their correct spots once we've

finished this procedure it is going to

be a little bit tricky to remove once

you've unscrewed it because it is hooked

in via the bottom so if you pull towards

you it will be significantly easier to

remove as pictured here give it a few

shots you can get it now there's five

cables you need to remove from the

motherboard the rightmost three will

pull down towards you and need not be

done in any particular order

now the left is quite the contrary you

will need to do the furthest left cable

first as the one right to the right of

it is below it so do the left one first

and then the one right to the right


now we need to remove the vibrating

motor which is in the top right hand

corner of the device it's held in by two

screws the left one is a lot longer than

the right stick those in the same spot

and then you'll be able to remove the

vibrating motor place that off to the

side with the screws as well now if you

remember the first plate we moved the

one that was held in by oh two screws

there was a cable directly underneath

that all you need to do is pop that up

with a screwdriver or a case opener tool

and then you will need to peel the

ribbon cable up now as you can see right

now underneath that peeled ribbon cable

there was a screw and there's one

directly opposite of the device as well

they're pretty noticeable

the one that is a little bit tricky to

find is the one under the ribbon cable

and you will need to pull the ribbon

cable up to do that feels like you're

going to break it because it is it he's

to the metal but fear not it won't break

you're good to go now wait before you

pull up this speaker if you check out

where my screwdriver is right now you

will see that there is a little diode

you need to remove this because this is

where the speaker gets its power if you

break this or rip this off you have the

potential of damaging the motherboard or

the speaker so be sure to remove that

little stud before you try and pull out

the speaker assembly then you're good to

go the speaker assembly comes out very

easily and place that off to the side

with the two screws you removed now if

you look about midway down the device by

the caution tab where the battery was

you will see that there is a white

looking dot and what's underneath that

is a screw now that white dot is

actually a water sensor so Apple can

tell if your phone has been dropped in

the water when you go to get it replace

oh you will need to peel that off remove

that don't worry you can stick it back

on later by just simply pressing on top

of it but then you will see the screw

that is revealed underneath and you will

just need to reveal that and pull that

out by unscrewing it place that off to

the side and be sure to keep track of it

now before we can pull the motherboard

out there is one more screw that needs

to be removed it's located right near

the vibrate motor and it is a bit of a

weird screw unfortunately it cannot be

removed with a Philips screwdriver and

you will need to go out and low

Gate a standard jeweler's flat-head

screwdriver in order to remove this

screw be careful because the area it's

in is a little bit sensitive and you do

not want to damage any of the components

now that all the screws have been

removed you can pull the motherboard out

just make sure that it doesn't cling to

any of the cables but other than that

it's very easy to remove now there are

ten additional screws that need to be

removed there are six that are along the

side of the device which are in red and

those are held with washers also so

there are two parts to that don't lose

the washers it reduces friction against

the frame and then there are four or the

yellow screws in each of the four

corners they come out pretty easy but

they take a little bit of time now we

need to separate the glass from the

frame so in order to do this grab a case

opener tool a credit card also works and

move it along the side of the device in

between the plastic and the frame itself

once you go around the whole thing

you'll notice that it will come out a

little bit easier it is add he's dat

some point so it may be a little bit

tricky to get off don't worry just take

your time and the frame will come out

very easy the cables on the back are a

little bit finicky so you need to watch

those make sure you don't break anything

else inside the frame but those cables

are good to go out of that slot

take your new digitizer and screen combo

that you ordered from I rescue comm and

pull it out of the packaging that they

give you we're now going to fit it back

into the frame so that we can put it

with the rest of the device so you're

going to feed the cables back the way

you got your original glass out through

that slot right there it's going to be a

little bit tricky and one thing you're

going to want to ensure is that the

cable behind the digitizer cable the one

that's on top is you want to make sure

that it goes through all the way and my

head gets in the way here I apologize

for that but you're going to want to

make sure that the cable goes all the

way through because it is a huge pain in

the butt if you accidentally pinch that

cable you also run the risk of ruining

the digitizer itself so ensure that

before you screw it in that screw is to

where it needs to be now we need to

place the ten screws that we're back on

the six with the washers and the four in

each respective corner

now that our digitizer has been fit we

need to throw the motherboard in there

as well make sure it's in the right

place and not on top of any cables make

sure it's above the three on the right

and below the two on the left now we

need to screw down the motherboard

there's two screws that need to be done

the weird funky one that we remember we

had to do with a Phillips screwdriver

and then the one that has the water

sensor on top once you have screwed the

two of those in we're going to fit the

speaker assembly in if you look at that

notch that's on it that needs to go

below the motherboard but the rest of

the speaker needs to go on top of it

it's a bit of a weird angle but if you

saw I kind of went in with a 45 degree

angle and you can push it down to where

it needs to go from there

once you have it fitted in the correct

spot you are going to need to screw it

in with the two screws it doesn't matter

what screw you put in which hole because

they're both the same length just ensure

that you tighten them enough but not

enough to strip the screws and or ruin

the LCD display below alright now we

need to pin all the ribbon cables down

first take the one on the side of the

device ribbon cables are a little bit

finicky so you just have to try your

best to get them in there they are trial

and error oriented you can try to align

them but honestly there's not a heck of

a lot you can do you either get it or

you don't

so spend a few minutes kind of look at

aligning it up correctly via a side

angle but once you get that shoved down

in there it is pretty easy to get those

dock connectors down so we've done this

one and it's nice and secure and now we

need to do the five on top there's the

three on the right and the two on the

left just as we undid them you can do

the three on the right in any particular

order it doesn't matter I go right to

left however the way you do it doesn't

matter and then we need to put the other

two cables which are on the left side

back down as well remember the most

right one if you're looking at the

device from backwards is the one that

needs to go down first it is the first

and preliminary cable it also is the

bigger one so the larger thicker cable

is the one that gets pinned down first

and then you move on to the second

lighter one now it comes time to place

the camera and put it in its spot and

then safely secure the ribbon cable

which is directly below it this one is a

little bit tougher to get on but don't

worry give it a few minutes and you'll

get it it is now time to put the back

plate on yet again with this back plate

what you're going to need to do is hook

it into the hooks that you probably

remember having to deal with the first

time make sure they're hooked in and

make sure that those three cables on the

right aren't in the way now you'll

notice that there are four different

types of screws there's a yellow screw

which is a lot shorter and a lot smaller

than all the other ones I think it's

blue threaded and that goes in that spot

the orange ones are the next shortest

ones they're both the same size and put

those in the orange one by the camera

and the rightmost screw the red one and

be very careful this is not the

longest one the teal one is the longest

one if you put the teal one in the red

spot you will crack your LCD so put the

next longest one in the red and then

lastly the longest in the teal spot now

we need to fix the side plate there are

two different screw lengths the longest

one goes to the right side so put the

long one and the bigger one on the right

and the smaller one goes on the left

side very simple very easy to do now if

you remember that little bracket dude we

had you're just going to stick him down

in there and he'll stay nice and easy as

long as you hold it if you let go of the

bracket it may move around while you're

trying to fix the battery now as for the

battery cable you're going to want to

make sure that none of it sticks out of

the outer casing insure that it does

stick against the device and stays near

the battery now the batteries which is

actually kind of difficult to get in so

for that ribbon cable you do need to

ensure that it is in the right spot but

once you are sure that it is aligned

correctly you need to add quite a bit of

force in order to get it to stay you're

then going to take your screwdriver with

the screw and screw that back into place

now take your back cover and set it

slightly apart now you're going to press

downward and re and close that take your

screws and screw the bottom of the phone

back up and that's it you've completed

your installation for checking and

troubleshooting always be sure to turn

the phone on make a telephone call go in

a dark room and make sure that the

ambient line sensors the proximity

sensors the speakerphone sensors the LCD

and the digitizer all work correctly
