1 General
When handling this product take care to keep all surfaces clean of dirt, dust, debris, and hand
grease. Use appropriate ESD precautions when working on this product. The use of finger cots or
gloves, an ESD mat, and an ESD wrist strap are required at minimum.
2 Disassembly
Tools:
• Torque screwdriver • Orange stick
• JCIS No. 0 bit • Nylon pointer
• Style 2A ESD-safe tweezers (Blunt Tip) • Front opening tool
NOTE! Whenever the phrase “pry tool” is used, a nylon pointer, an orange stick, or a front
opening tool may be used, depending on the user’s preference.
Step-by-Step Instructions
1. Locate the grip location on the battery cover that
is just below the camera window.
2. Remove the battery cover by pressing down on
grip location and simultaneously sliding battery
door towards the bottom of the phone (away
from the camera) until a 4 to 5 MM gap forms
between the bottom of camera window and top
of the battery cover. The battery cover can then
be lifted away from the phone.
3. Remove the battery by placing your hand over
the battery cavity and orienting the phone so that
the battery cavity is in a downward position.
The battery should drop into your hand.
NOTE! Do not tap the phone against a hard
surface in an attempt to get the battery
out. Damage to the phone may result!

Step-by-Step Instructions
NOTE! Be careful not to scratch or scar the
phone or the flip hinge cover when
removing the flip hinge cover.
4. With the flip in the closed position, slide the flat
end of a pry tool under one of the accessible
corners of the flip hinge cover and rotate the pry
tool away from the system connector. The hinge
cover should start to separate from the phone
along the edge adjacent to the system connector.
5. Once you have got the separation of the flip
hinge cover started, work the pry tool along the
flip hinge cover’s separating edge to finish
releasing it from the phone.
6. Once the edge of the flip hinge cover is released
from the phone, lift the hinge cover’s free edge
up and out away from the phone as shown. The
flip hinge cover should easily slide out from
between the flip and the front cover when lifted
in the manner shown.
7. Using a torque driver with a JCIS No. 0 bit,
remove the two M1.4 x 3.5MM screws holding
the flip assembly.
NOTE! Do not reuse the screws that hold the
flip assembly in place.

8. Support the hinge joint by placing your finger on
the black portion of the hinge.
9. Then rotate the flip so that it forms a 90º angle
with the rest of the phone.
10. Remove your finger from the black portion of
the hinge and rotate the flip away from the
phone. While rotating the flip, it should come
free from the phone.
11. Orient the phone so that the side of the phone
with the camera is towards you and the end of
the phone with the system connector is the
bottom of the phone.
12. Insert the pointed end of the nylon pointer into
small hole in the RF port cover and rotate the
nylon pointer down towards the outer edge of the
phone. The RF port cover should lift from it
cavity.
13. Using a pair of tweezers, press inward on side of
the left side screw cover that is accessible from
the RF port opening. While applying inward
pressure on the left side screw cover, pry the
cover upward way from the phone.
14. Once the left side screw cover is loose, remove it
from the phone.

15. Using the pair of tweezers, press the tip of one of
the tweezers’ arms down into the notch in the
right side screw cover and pry the cover up out
of its cavity.
16. Once the sides of the right side screw cover are
accessible, lift it from the phone using the
tweezers.
NOTE! If the disassembly procedure is only
being preformed for the purpose of
removing the front cover, the following
two steps can be skipped. Otherwise the
following two steps need to be
preformed before removing the front
cover.
17. If present, remove the memory stick.
18. If present, remove the SIM card.
19. Remove the four screws from the back cover
using a torque driver with a JCIS No. 0 bit.
NOTE! The two screws near the system
connector cannot be reused. The two
screws near the camera window are self-
tapping screws and can be reused.

Step-by-Step Instructions
20. Starting at the end of the phone that contains the
system connector, work a pry tool in the seam
between the front and back covers and gently
twist the pry tool to separate the covers.
21. Once the separation of the front and back covers
is started at the bottom of the phone, move to
one of the seams that run along each side of the
phone where the front and back covers come
together. Using the flat end of a pry tool, gently
twist the pry tool to separate the front and back
covers. As the seam opens up, switch from side
to side working the seam open by sliding the pry
tool down the seam and twisting. Continue
doing this back and forth along each side until
the seams are opened up on each side just passed
where the top of the display is located.
22. Remove the front cover by lifting up and rotating
it away from the end of the phone with the
system connector.

NOTE! The display is connected to the non-
accessible side of the circuit board.
Therefore the circuit board has to be
removed from the back cover before the
display can be disconnected from the
circuit board.
NOTE! Be careful not to damage the display or
its flex film while trying the remove
the circuit board from the back cover.
23. Lay a scrap front cover, external side up,
adjacent to the side of the back cover that the
camera key is located on and rotate the display
so that it is laying on top of the scrap front cover.
24. Remove the two screws from the shielding can
using a torque driver with a JCIS No. 0 bit.
25. Then lift the shield can away from the circuit
board.

26. There are 5 latches that hold the circuit board in
the back cover. To release the circuit board,
gently pry between the circuit board and the
back cover in the 4 locations indicated in the
order specified.
NOTE! Only pry as much as is needed to
release the latches!
NOTE! When prying in location 2 make not to
pry over the portion of the antenna that
is visible.
NOTE! Be careful not to damage the RF port
when prying to release the latches at
location 2.
27. Once the latches holding the circuit board are
released, slightly lift up the side of the circuit
board the display is adjacent to and using a pry
tool, carefully disconnect the flex connection of
the display from the circuit board. Then set the
display aside.
28. Once the display is removed, increase the size of
the opening between the circuit board and the
back cover and locate the jog dial flex film
connection.
29. Using a pry tool, carefully disconnect the flex
connection of the jog dial from the circuit board.
