HTC display
replacement procedure – How to replace the display of HTC Evo 4G
Gently
insert an iPod opening tool between the rear panel and the inner rear frame
near the headphone jack. Use your iPod opening tool to pry up the rear case
around the perimeter of the Evo.
Lift the
rear panel off of the inner rear frame.
Using the
tip of your finger, lift the battery from the end closest to the camera. Remove
the battery from the rear inner frame.
Use the
flat end of a spudger to pry up the red MicroSD retainer attached o the inner
frame. The retainer will move about 1 mm and stop. Do not attempt to completely
remove the MicroSD card retainer.
Use a pair
of tweezers to carefully pull the MicroSD card out of its slot in the inner
rear frame.
Remove six
T5 Torx screws securing the rear inner frame to the inner case.
Gently
insert an iPod opening tool between the rear inner frame and its plastic
surround near the Micro HDMI port. Carefully pry the top edge of the rear inner
frame away from the front surround of the Evo.
Insert the
iPod opening tool between the rear inner frame and its plastic surround and pry
up at several points along the left edge of the Evo.
Continue
the prying procedure, now focusing on detaching the plastic surround from the
bottom of the Evo. Pry up the rear inner frame along the right edge using the
method described in previous steps. Eventually work around the entire perimeter
of the rear inner frame until it is lifted slightly from the inner case.
Remove the
rear inner frame from the rest of the Evo.
Remove the
single Phillips screw securing the logic board to the inner case near the
headphone jack.
Use the
flat end of a spudger to pry the logic board off the posts securing it to the
metal display tray. Do not try to completely remove the logic board just yet.
It is still attached by three ribbon cables.
Carefully
peel the device information sticker off the left edge of the logic board and
EMI shield to reveal three connectors covered with tape. It is not necessary to
peel the entire device information sticker off the EMI shield.
Fold the
device information sticker up against the top of the logic board to keep it out
of the way while you work. Remove the pieces of tape covering the following
ribbon cables:
Front-facing
camera
Front panel ribbon cable
Display ribbon cable
Front panel ribbon cable
Display ribbon cable
Using the
tip of an iPod opening tool, flip up the front-facing camera ribbon cable
retaining flap. Be very careful and gentle with these flaps. They are very easy
to break or dislodge and equally difficult to reinstall. Use a pair of tweezers
to pull the front-facing camera ribbon cable straight out of its socket.
Using the
tip of an iPod opening tool, flip up the front panel ribbon cable retaining
flap. Use a pair of tweezers to pull the front panel ribbon cable straight out
of its socket.
Using the
tip of an iPod opening tool, flip up the display ribbon cable retaining flap.
Grasp the display ribbon cable with a pair of tweezers and pull it straight out
of its socket.
Carefully
lift the logic board out of the inner case, minding any cables that may get
caught. Be mindful of the top power button and side rocker switch, which may
fall out of the front case when the board is removed. Gently lift the
front-facing camera out of its recess in the inner case and remove it from the
Evo.
In the
following steps, you will use a heat gun to soften the adhesive securing the
outer black border around the underside of the front glass panel to the inner
case.
With the
heat gun set to low, start by heating the outer black border near the upper
left corner of the glass panel. Try not to excessively heat the outer plastic
edge of the Evo. Due to the heat applied, it is normal for a layer of
condensation to develop on the inside of the glass panel and/or the outside of
the LCD. It can be removed with glass cleaner once the glass is separated from
the display.
Gently insert an iPod opening tool between the glass front panel and its plastic surround near the upper top left corner of the Evo. Carefully pry up the glass, being careful not to bend it excessively. The key is to work slowly and gently to avoid breaking internal components.

Use a heat
gun to soften the adhesive along the left side of the front glass panel.
Insert the
iPod opening tool between the front panel and its plastic surround and pry up a
several points along the left edge of the Evo.
Continue
the heating and prying procedure, now focusing on detaching the bottom of the
front panel from the plastic surround. Pry along the bottom edge of the Evo to
further separate the front panel from the rest of the device.
Use a heat
gun to soften the adhesive along the right side of the front glass panel.
Pry up the
front panel along the right edge using the method described in previous steps.
Eventually work around the entire perimeter of the front panel until it is
lifted slightly from the inner case. Don't try to completely remove the front
panel just yet. Its ribbon cable is still attached to the inner case.
Peel the
front panel ribbon cable off the adhesive securing it to the metal underside of
the inner case.
Lift the
front panel out of the inner case, minding the cable still routed through the
bottom of the Evo. Carefully de-route the front panel ribbon cable through the
slot in the inner case. Remove the front panel. Notice the four (4) clear
plastic hooks that are adhered behind the menu buttons. Look closely. Each one
is shaped differently and in a particular orientation. If the replacement front
panel does not have these installed already, carefully remove and transfer them
from the old panel to the replacement.
Peel the
piece of tape connecting the underside of the LCD metal tray to the bottom of
the inner case.
In the
following steps, you will use a heat gun to soften the adhesive securing the
underside of the LCD panel to the inner case. The area the adhesive is applied
to is shown in red in the second picture (with the LCD removed). Use your heat
gun to soften the adhesive under the LCD panel along its left edge.
To gain
enough clearance to insert an iPod opening tool, it is necessary to
simultaneously push the LCD panel outwards while prying along the edges. It is
recommended to push through the opening located near the bottom left corner of
the Evo. Insert an iPod opening tool with the edge angled up toward the
underside of the display between the backlight and the metal shield beneath it.
Gently
insert an iPod opening tool between the LCD panel and its plastic surround near
the top left corner of the Evo. Use the iPod opening tool as a lever to pry the
LCD panel away from its plastic surround.

panel and its plastic surround and pry up at several points along the right
edge of the Evo.
Lift the
