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
and rotating the pry tool so that the flat edge of
the tool moves into a vertical orientation.
3. While lifting up the edge of the antenna cover
adjacent to the battery cavity, slide the cover
towards the top of the phone.
4. Once the antenna cover reaches the point where
it will no longer slide forward, lift the antenna
cover off of the phone.
5. Remove the six screws indicated.

6. Remove the front cover assembly from the back
frame.
NOTE!
The label tends to adhere to the top of
the shield can on the phone board that is
below the battery connector. Be careful
not to damage the label when removing
the phone board in the event that the
needed repair does not require label
replacement.
7. To remove the phone board and avoid damaging
the label, slightly lift the top corner of the phone
board that is near the speaker port.
