  • First of all remove the back cover (battery cover) of the phone using a safe open pry tool. Carefully insert the pry tool between the edge at the back of the phone as indicated by the arrows in figure 1 and pry the cover off. The battery cover should come off quite easily.

  • Remove the battery and the SD card from the phone as well. To remove the SD card you will need to pop the tab first at the location shown in figure 2 and then take out the SD card. You may use a pair of tweezers if you find it difficult to remove the memory card with your hand.
  • Now in order to remove the back-frame of the phone you will need to unscrew six Torx screws. Using a T5 Torx screwdriver, remove these six screws from the locations shown in the figure 2.

  • Once you have removed the screws you can carefully pry the back-frame off using safe open pry tool. Insert safe open pry tool between the edge that separates the frame and the body of the phone and run it along the sides to unclip the clips. The removed back-frame will look similar to the figure 3.

  • The next step is to remove the mainboard (logic board) from the unit. In order to remove the mainboard you will have to unscrew a Phillips screw first and then detach three ribbon cable connectors.
  • Remove the screw first using a small Phillips screwdriver from the location shown in the figure 4 by a small circle 1.
  • Disconnect the three ribbon cable connectors using safe open pry tool at the locations A, B and C in the figure 4.

  • The mainboard will now be released and you can take it off from the phone assembly and put it aside.
  • Lift out the camera from its location indicated by orange arrow in figure 5 and then carefully pry up the ribbon cable which will be glued at the back of LCD indicated by gray arrow in figure 5. Note that you need to lift up this cable from its colored end (which you have disconnected from the mainboard) and then pry it off from the back of LCD. Do not pull it off completely from the unit because it is a part of glass screen (touch screen digitizer).
  • Using a safe open pry tool, carefully pry up the front glass screen from the unit. Note that the glass screen will be adhered to the unit all along the sides with an adhesive material and you may have to use a hot air gun / hair-dryer before prying up the front glass screen.
  • After you have the glass screen digitizer completely pried off, gently lift it up from the unit because you will have to run the ribbon cable through the gap to completely separate it from the assembly.

The HTC EVO 4G is now disassembled and you can replace the damaged part(s) with new ones. Reverse the instructions above to reassemble your phone.
