How To Make Your iPhone Look Brand New

Post  kyrilman on Sat 6 Mar 2010 - 16:00

(Just like to thank everyone who posted/shared this link with friends, I am glad this guide has reached several others )

Seen a lot of threads of people wondering how to restore an iPhone so I decided to make a DIY guide

Also pretty helpful if you want to de-brand your iPhone Razz

Background

My previous iPhone was stolen at the gym, low on funds I decided to buy
the cheapest iPhone I could find that worked regardless of condition. I
found an iPhone 3G that had being completely abused and had a dark spot
on the LCD. On the second picture notice the gouge on the right side,
out of of all the blemishes it was the deepest) Still I ended up buying
the phone for a really good price. The replacement parts from eBay only
cost $16 for the glass and $23 for the LCD ( sanding kit $10) making it
a price effective mod.




My first attempt at restoring it was a mild success, since I used mild
sandpapers/rushed. But you can see that even with 800 grit sandpaper
and about an hour I got it looking better, but it still had tons of
deep dents and scratches.




Warning Warning Warning Warning

Do this at your own risk. I am posting this here only to document how I
restored a completely busted iPhone. One thing I should mention first
is that iPhone Rear plastic has a scratch-resistant coating
The iPhone rear plastic is composed of the following

1) The most inside layer is a thin colored plastic ( black or white).
2) Above that is a clear polycarbonate plastic layer.
3) Above that is the apple logo and writing.
4) Above that finally is a pretty good layer of scratch-resistant coating.

If your phone only has a few light scratches, only use the most
aggressive sandpaper you have to, in order to remove the scratches. My
recommendation is that you try to remove 90-95% of scratches without
trying to remove 100%. This way you keep the scratch-resistant coating,
which will protect from future scratches.

Rule of thumb, if you start noticing that you are removing the
apple logo, or that you start seeing a darker plastic, you have gone
too far (either stop, or continue based on what you are going for) (
Look at #1)




On my phone I had to remove all the scratch-resistant
coating because several of the scratches were much much deeper than the
coating. It scratches a lot easier now, so if you can avoid doing so,
please please please leave the scratch-resistant coating on ( no point
in polishing your phone just to see it get marred again)

I can't stress this enough, If you remove the scratch-resistant coating it will scratch a lot easier ( you have been warned Razz )

Restoring the back

This is a complete and comprehensive wetsanding guide. If
you have never wetsanded before, or wonder why you never get good
results this should help. This will let you restore anything that is
plastic, or using harder/ finer grits you can polish
metal/aluminum/painted parts. I apologize for the length of the guide
but I think the tips here will help you get great results.

Tools:
Sandpaper 320(or 500),800,1000,1500,2000,2500,3000 grit
3M Rubbing compound
Machine Polisher ( Power Drill or small buffer)
Microfibers
Sticky tack and or tape

If you want to save time and money I recommend just purchasing a 3M
headlight restoration kit (available at almost all car part stores)

$10 bucks at amazon right now
http://www.amazon.com/3M-Headlight-L.../dp/B001AIZ5HY



It will have almost everything you need, but you still need to buy 1000,1500 and 2000 grit sandpaper + a microfiber on the side

Directions :

Step 1: Decide and Drysand with first grit

(always when sanding keep a thumb/finger above the camera to avoid scratching the glass lens ! )

Dry sand with the least aggressive sandpaper needed to remove
scratches. If you have deep scratches you may have to go down to
320-800, but if you have light scratches, 1000 or 1500 might be enough.
The best way to test this is to run your fingernail around your phone
and try to find a deep scratch. Start at a high grit ( 1500) and see if
that removes the scracthes. If you still see deep scratches, try the
next most aggressive grit, etc. For me I had to go all the way down to
320 grit, due to several 2-3mm deep defects. This first step is really
time intensive, but make sure you don't use water, on the first step
because it tends to hide scratches. When you dry sand you can see all
the fine sanding marks you are making which allows you to see the
scratches you haven't removed. Dry sanding clogs sandpaper, but you can
either buy more sandpaper or wash the sandpaper in water and dry it
before you use it. Before you finish this first step, make sure all
your sanding marks are in one direction; you'll see why later.



Step 2: Wetsand with remaining grits

1) Use very little water when you wetsand ( don't want to kill you iPhone)
2) Make sure the previous sanding marks are completely gone before moving on to the next higher grit

The 2nd point is important, and the reason many people get poor results
when wetsanding. It's a simple technique but it takes practice/patience
to get right. But here are some tips:

a) Before moving on to a higher grit make sure all your sanding lines
are in the same direction. When you first start sanding the part you
can sand in any direction you want, but before you move to a higher
grit make sure to sand the entire part down in one direction
b) When you have moved to your next higher grit you don't have to sand
in a single perpendicular direction (a common myth). Just try to sand
the part down as best you can in any direction. However Before you
move on to a higher grit, make sure you sand perpendicular to the grit
you before. This will let you know where you have to keep sanding
before moving on.

So if your last sanding marks using 800 grit were left to right , the
last sanding marks on 1000 should be top to bottom, then 1500 should be
left to right, etc


c) Before you move on, dry the part a bit, to make sure all the
previous sanding marks are gone ( again water tends to hide scratches )


The most time consuming jumps for me were sanding 800grit lines with
1000 grit , and the 1000 grit lines with 1500 grit. These two are time
consuming steps , but make sure you take your time, because the finer
grit sandpapers will be unable to remove these deep marks (especially
800 grit lines).

When wetsanding the phone it should look like below, not too much water
and a slight white film. I kept all my wetsanding paper in a bowl of
water, and then dried it on a towel on my lap before using it on the
phone. You want the paper to be wet, but not running !


After 1500

After 3000


In all these pictures you will notice a few things
a) All the sanding marks are in one direction, and you can see that there are Zero sanding marks in any other direction.
b) The phone is dry


You may be wondering why all my sanding marks are lengthwise. When I
wetsand I still follow what I said above ( last step is to sand in the
perpendicular direction to make sure all the previous sanding marks are
gone) but then additionally I lightly sand in the longest dimension of
the part, this helps me make sure I haven't left any deep sanding marks
of the similar grit ( ie, I lightly sand 1000 grit sanding line with
1000grit sandpaper so that sanding with 1500 is easier)

Step 3: Cover openings

Before you start polishing make sure you cover up your headphone port,
volume buttons, vibrate button and 30 pin dock with sticky tack (that
blue stuff). You can cover the camera glass, but the polishing
compounds are not abrasiveness enough to scratch it (unlike the
sandpaper). Sticky tack is easy to apply, and come off in one piece.
Tape will probably work too but I found that the tape kept lifting off
when I was buffing. Refer to the #2 in the following picture (the gray
stuff)




Step 4: Polish

I used two kinds of polishes (using one will work, but you will have to repeat it multiple times/results will vary)

I used the Orange 3m pad with 3M rubbing compound on a power drill
You can sanding halo marks


You can then finish with the 3M rubbing compound using a microfiber and you will get almost near perfect results !

(Completely optional)

If you have access detailing products or a friend who details cars
I polished with a blue 3M Pad with Meguair's 205 paint polish ( you can also use Scratch-x since its pretty mild polish).

I then finished with some Meguair's NXT 2.0 wax

Results = completely flawless mirror finish

Restoring the front

Not a comprehensive guide ( sure you can find a video or guide online)
but I posted a few tips that I read from different users online,
especially the ones that make things easier/lower risk of damaging your
iPhone.

The replacement parts for the Phone are dirt cheap ( $16 for the glass, $23 for the LCD)

Tools

Heat gun ( or a blow dryer)
Latex Gloves
Compressed Air ( I'm cheap so i use a small bike pump)
Suction cup ( i used one that was too big but still worked)
Prying tools
E-xacto blade ( or something flat and thin)
Small Phillips screwdriver
Replacement parts ( I replaced the LCD and front glass)



Step 1 Opening iPhone

1) Take out two bottom screws (blue arrows)
2) Use suction cup ( place it around the home button) and flip the glass up
3) You will see connectors and numbers. Use the prying tool and lift
the number one and number two connector. For the number three connector
lift the flap and pull the screen away. ( Red arrows)



Step 2 Remove LCD tray from Frame/Touchscreen

1) Remove the tape on the side of the LCD ( black)
2) Remove the remaining screws ( blue)
3) Use a prying tool on the side of the LCD tray to lift the LCD slightly
4) Once the lcd has been lifter slightly use that small little hole on
the bottom to slide the LCD down. ( safest way to remove LCD)

Step 2 Removing OLD LCD

1) You will have to unstick your old LCD from the aluminum tray ( this
will ruin your OLD LCD, because the rear reflective material of the LCD
will staty stuck to the LCD tray)
2) Remove old LCD reflective material (its like a mirror) and clean off the old adhesive
3) Test fit the new LCD ( it lines up with two small plastic nibs and two holes on the LCD tray
4) Remove the rear plastic from the new LCD, and stick it on the LCD tray ( you have to do this right the first step !)
5) When you are done use the old LCD as you template, and make small
folds in the LCD cable connector ( you need it to be folded
identically)



Step 3 Replacing front glass

I didn't take many pictures because, well its a pretty simple thing
procedure, that is very difficult to do correctly. It's like removing
the aluminum foil from a Hershey's bar. It's easy to do, but in the
process the aluminum foil gets a bit wrinkled

1) Heat up the Glass and Plastic frame ( I can't really say how long
depending on what you use, but a good sign is if you start to smell a
little bit of plastic, that's a good signt

2) Someohow, either using your fingers or a prying tool, remove the
glass/touchscreen from the frame. This will probably crack the lcd, and
actually that makes it a bit easier. I heard from a friend, that if you
already have a cracked glass, removing it is a bit easier than trying
to remove it as an entire piece.



3) Clean off all the old residue, and if you bent your frame alittle, bend it back in to shape.

4) Apply the new adhesive strips ( pretty easy ) make sure that you
when you buy the touchscreen/glass it comes with two new strips

5) Before you apply the touchscreen/glass put on some latex gloves ( from now until you are finish) and peel the inside screen protector away a bit, and tape down the cables



6)Remove the adhesive from the two strips and place the new glass on your plastic frame (take your time )

Step 4 Put New LCD back in

7) Remove the inside screen protector of the Glass/touchscreen and put
it glass side up ( to avoid dust). Then remove the lcd screen protector
and keep it in your hand ( you want to avoid getting any dust on it ).
Before you snap the new LCD into the frame, make sure there in no
dust/lint on either part ( used the compressed air before you put
everything together, DON'T use the microfiber since they have lint)

Step 5 Put everything back together

Just the reverse, pretty easy. Before you put the screws on the LCD
tray, make sure you didn't get any dust, if you did unsnap the lcd,
used the compressed air to get it clean and put it back together. The
only tricky connector is the #3 one, but its not too hard. Then you
when you put the glass back into your iPhone, slide the top part first
( by the headset) and then the bottom part) and you are done !



Optional

I Love how clear the glass is, but I hate how easy it gets scratched.
Right after you take off the front plastic film you can put on a screen
protector without having to clean the glass
