1 Disassembly
• Tools: torque screwdriver, T6 Torx® bit, ESD-safe tweezers, orange stick, nylon pointer, 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
NOTE! Keep all contact surfaces clean of dirt
and hand grease! Use finger cots or
gloves, and an ESD wrist strap!
1. Remove the battery cover by sliding it down
towards the bottom of the phone and lifting it
off.
2. Remove the battery by inserting a pry tool
underneath the tab at the bottom of the battery

3.13 Vibrator
• Tools: ESD-safe tweezers, orange stick, nylon pointer, 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.
• Disassembly steps 1- 6
Step-by-Step Instructions
NOTE! Keep all contact surfaces clean of dirt
and hand grease! Use finger cots or
gloves, and an ESD wrist strap!
1. Gently pry underneath the vibrator weight to
remove it from the front cover.
2. Place a new vibrator into the front cover as
shown. Make sure that the weight is toward the

3.14 Label Replacement
• Tools: ESD-safe tweezers, hot air gun
• Disassembly steps 1- 2
Step-by-Step Instructions
NOTE! This instruction should be used when
exchanging an old label or mounting a
new one.
1. Print a new label.
NOTE! The text must be fully readable manually
and mechanically.
NOTE! If one label or less is present on the
phone, proceed to step 3. If two or more
labels are on the phone, proceed to Step
2.
2. Carefully remove the old labels.
NOTE! If difficulty in removing the old labels is
experienced, try heating up the old
label(s) with a hot air gun to loosen the
adhesive bond.
NOTE! Avoid scratching the frame when trying
to peel off of the labels.
NOTE! Make sure that all adhesive residue is
removed. Carefully clean off any
residue in the label area.
NOTE! No more than two labels are allowed
on the battery cavity.
3. Place the new label into the battery cavity.
Center the label so that the notches in the label
are lined up to the center screw openings, the
battery connection at the top of the battery
cavity, and the edges of the SIM card opening.
4. Once the label is correctly positioned, carefully
smooth the label into place.

2. Before installing the antenna assembly onto
the new back frame, check whether the
board connection portion of the antenna has
become detached from the antenna base. If
it has become detached, press that portion of
the antenna back into place so that it adheres
to the antenna base as shown.

3. When placing the antenna assembly, align the
notch in the antenna assembly with the
corresponding alignment features along the top
edge of the new back frame’s battery cavity.
4. Once aligned, rotate the antenna assembly down
into place on the back frame. Make sure that the
board connection portion of the antenna
assembly fits securely into the appropriate
opening at the top right side of the back frame.
5. Apply pressure over the entire surface of the
antenna assembly to ensure a good adhesive
bond to the back frame.
6. Remove the polyphonic speaker/grommet
assembly from the old back frame.
