0. Intro

First a legal DISCLAIMER: Instructions and pictures are provided "AS
IS"; this procedure works for me and my particular n10, your model may
vary. If you follow this you do so at your own risk; under no
circumstances will I accept responsibility for any damage you do to
your (or others') property, or any loss of warranty.

But now to the fun stuff. Disassembling the n10 is easiestly viewed as
a two-step procedure. First, get rid of the silvery outer cover (that
gives it the unnecessary cheap touch) and second take off the display
frame that's attached to the PCB. I suggest you look at <> to get an
idea what it looks like when you're half way there.

Overall, it's quite simple, if you know where to push and what to
loosen next. All the tools you need are a small Phillips head
screwdriver and a small, simple flat screwdriver. If you have a
millimeter of fingernails left and are a little skilled in fine
mechanics then you're perfect.

Before you start I suggest you lock the buttons with the "hold" switch
and switch off the main power (bottom right).

1. outer (silvery) cover
    
 case screws

Hidden behind 4 round black rubber pads you find the main case screws.
You can remove the pads with a bent paper clip; clean everything from
the glue if you like.

Now check your Phillips screwdriver, preferably a watch maker's
one. If it fits these screws, it will fit all of them. The screw's
fine thread seems to be metric and rests in a metal hold; not like the
self tapping plastic crap. I really liked it when I first noticed.

 case clamps

Now the case is still clamped shut. The biggest, strongest clamps are
at the bottom, next to the mini USB connector, and none are at the top
(CF / earphones). So start at the top to bend the case open, twisting
and pushing the case carefully. You may use the flat screw driver to
release the side clamps, if you can find them, but be careful not to
damage the case. What comes off from everything else is the rear
cover. The side clamps don't seem to mind being forced open. For the
bottom clamps I wouldn't try !


 battery

Looks like you haven't gained much. 2 visible screws, everything still
fixed in there. Don't loosen those screws yet, it's useless and confusing.

Instead unplug the battery, using finger nails or a screwdriver. You
can then lever the battery with the screwdriver carefully; it's only
glued to its frame with double faced adhesive tape. Be easy with your
force and the screwdriver and loosen it.

 battery frame

The battery frame is simply clamped to the PCB, and fortunately not
very hard. You can easily bend these clamps with the screwdriver and
take of the frame. Now you can see a third screw, but must still leave
them alone.

front cover

If you still have the protecting foil on your display, now is the time
to at least loosen it from the front cover, which is now to be
separated from the display.

 case clamps

Like with the back cover, push or carefully force the clamps that hold
the front cover.

2. side/display frame

 speaker connector

The speaker sits on the display frame. Because on my first try I had
the front cover still on, it took me a while to realise it was the
speaker connector preventing further disassembly -- sheesh ! Unplug it
with finger nails or screwdriver.

 button sheet

Now release the thin metal sheet around the "joystick" and the other 4
main buttons. 2 simple screws.

 display frame screws

Finally. Time to undo the three screws from the back side. The
display, loosely sitting in its frame, will come off. But watch out
for those filigrane...

 connectors

they are thick film connectors, locked into place by sort of
plugs. First pull the plug out of the socket, then the film connector.


I stopped here, didn't take off the main display connector because I
assumed it was too messy putting it back on and everything was
accesible already.

Reassemble in reverse order. If you still have the display foil, watch
it when putting on the front cover.

Lock in the rear cover at the bottom an pivot it shut. Make sure the
bottom clamps snap in first, so you can easily correct misfit.

Good Luck !
