DISASSEMBLING
PROCEDURE
Flip
your phone over and hold the phone with the back facing you.
Place
the prying tool into the notch at the bottom of the case and pull up to remove.
Use
the plastic prying tool in the upper left-hand corner notch of the battery to
remove.
Remove
the two T5x5mm Screws with the T5 Torx Screw driver. Remove the one Phillips
screw with the Phillips #00 Screwdriver.
Use
the plastic opening tools to remove the back case. There are four T5x5mm
screws. Use the T5 Torx Screwdriver to remove them. Using the plastic opening
tools, remove the Wifi antenna.
There
are three button ribbons on the phone that need to be pulled down off of the
case. With the plastic opening tools, pull the button ribbons down away from
the frame without completely removing them.
After
making sure the button ribbons are away from the frame, insert the plastic
opening tool into the frame and remove it. Remove two Philips screws holding
the Motherboard in place.
Three
ribbon cables and the vibration motor need to be disconnected from the
Motherboard. Using the plastic opening tools, pull up on the power button
ribbon to gently detach it. Remove the vibration motor by gently pulling it off
of the Motherboard.
Remove
the digitizer ribbon cable with the plastic opening tools. Remove the LCD ribon
cable from its connector. It is now safe to release the Motherboard from the
clips holding it in place. Start at the top clip of the phone and move your way
around gently releasing each clip.
Do
not lift the Motherboard off the phone. The LCD Ribbon is still connected to
it. Lift the Motherboard towards the left to expose the LCD clamp connector.
Open the clamp connector of the LCD ribbon by carefully pulling it up with the
plastic opening tools.
The
Motherboard is now removed.
After
removing the motherboard from the phone, the button bar is exposed and easily
replaced. Use the plastic opening tools to remove the button bar and replace it
with the new one.
