LG Optimus G Pro
Once
you have access to the phone, there is a small indent on the bottom left side.
Use your fingernail or a plastic opening tool to pry from here and pull off the
back casing.
Once
you have properly removed the outer casing, the back should look as so. To
remove the battery, pull up from the red mark using your finger. The battery
should come up at an angle, and easily be able to be removed. Once the battery
is removed you may safely proceed to the next step.
Make
sure you remove the battery first. You will see that there are 14 screws on the
back of the inner case. Use the Phillips head screwdriver to remove each of the
screws, make sure to put the screws in a safe place where they will not get
lost.
Once
you have removed all the screws, you can begin removing the inside cover.
Insert the opening tool using a sliding motion into one of the corners and move
it along the edges of the inside cover. This will loosen the edges and the
inside cover will pry apart from the shell.
The
inner cover is now removed, you now have access to the many parts on the inside
of the phone.
Using
a plastic opening tool, pry the connection between the cable and the phone.
With even pressure the cable should disconnect from the logic board easily.
After
removing the the Ribbon Cable, the Rear-Facing Camera should be able to be
removed easily with your fingers.
Using
your plastic opening tool, disconnect the connection between the phone and the
ribbon cable. Make sure to use even pressure as you apply it to the cable.
In
this next step it is easy to pry the wrong piece. Make sure to pry at the metal
platform that the sister board sits on, not the orange printed circuit board
itself. Using your prying tool, pry at the right red marked corner, making sure
to pull at the metal platform under the circuit board. Once it is raised
slightly, pull along the underside until the left red mark. This should loosen
the board and allow it to be removed. If it's still unable to be removed, try
to pry at the orange mark, making sure to pull at the same metal platform.
You
can now raise and remove the sisterboard with your plastic opening tool or your
fingers.
Use
the plastic opening tool to disconnect the 4 ribbon cable connections and the
antenna attached to the logic board.
The
logic board is connected to the under side of the phone with a bit of adhesive.
Using a spudger, place it under the logic board from the top right corner and
gently slide it toward the center orange mark where the adhesive is. Apply
a little bit of pressure parallel to the logic board and the Logic board should
loosen from the phone.
