    • The iPod Touch 4th Generation front panel is attached to the rear case by adhesive. The use of a heat gun to soften the adhesive is highly recommended.

    • With the heat gun set on "low", begin heating the lower portion of the Touch near the home button.

    • It is suggested to heat the desired portion in a circular motion pattern to evenly dissipate the amount of heat throughout the device.

    • Beware, as the Touch will be very hot. It may be helpful to hold it with a towel while prying.

    • Insert the edge of an iPod opening tool between the front glass panel and the plastic bezel near the home button.

    • Do not try to pry between the plastic bezel and the steel rear case.

    • Pry the bottom edge of the front panel upward, being careful not to bend the glass excessively.

    • If it is too difficult to pry up the front panel assembly, reheat it and try again.

    • Due to the construction of the 4th generation Touch, the digitizer cable cannot be disconnected until the logic board is removed. Use extreme caution when handling the front panel assembly, as it is attached to the rest of the Touch by the very delicate digitizer cable.

    • Also, the display data cable is very short and is connected to the logic board near the top of the front panel assembly. If it does not become disconnected while freeing the top edge of the front panel assembly, be sure to disconnect it with an iPod opening tool before rotating the front panel assembly out of the Touch.

    • Carefully pull the top of the front panel assembly away from the adhesive holding it to the Touch, minding the short digitizer cable connecting the two components.

    • Insert the edge of an opening tool under the steel mid plate near the bottom left corner of the Touch.

    • Slowly pry upward to separate the plate from the adhesive securing it to the plastic inner case.

    • If the plate is still attached to the logic board, re-warm the area to loosen the adhesive, then slowly separate the plate from the logic board using the opening tool.

    • There is a thin, fragile ribbon cable underneath the plate. As you pry the plate up, be very careful not to rip the cable.

    • This cable may stick to the plate and will tear very easily if you're not careful. Work slowly and be careful not to strain the cable.

    • Use an iPod opening tool to slightly lift the edge of the logic board next to the battery enough to grab it with your other hand.

    • Do not excessively bend the logic board, as it is very thin and fragile.

    • Be very careful not to lift too much as the volume control ribbon cable is still connected and will tear very easily.

    • While gently lifting the logic board with one hand, use an iPod opening tool to lift the logic board near the copper tape at the logic board's top edge.

    • The logic board will be lifted adequately when the last display assembly connector has cleared the top edge of the rear case.

    • With a plastic opening tool, gently pry the iPod's speaker out of its recess in the outer case.

    • Do not try to completely remove the speaker. It is still soldered to the underside of the logic board.

    • Allow the speaker to rest above the battery so that you can proceed with battery installation.

    • In the next few steps, you will loosen the adhesive from underneath the battery, the logic board, and the frame under the battery. Do this slowly, carefully, and evenly. Take care not to puncture the battery or bend the logic board.

    • Use a plastic opening tool to pry up the adhesive around the three exposed edges of the battery.

    • Do not try to pry the battery out, just start loosening the adhesive.

  17. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 17, imagen 1 de 2 iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 17, imagen 2 de 2
    • After the edges of the battery are loosened, begin prying up the edge of the logic board. Start at the top and work your way down the side of the board.

    • To prevent bending/breaking the logic board, do not try to remove the logic board, yet. The dock connector is still embedded in the frame. Again, you are only trying to loosen more of the adhesive.

  18. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 18, imagen 1 de 2 iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 18, imagen 2 de 2
    • With a plastic opening tool, carefully push the dock connector out of its outer case recess. Work each corner evenly until the connector comes free.

    • Since the dock connector is attached to the logic board, pushing it out of the case may cause the logic board to begin to flex. Take extra care not to permanently warp the board.

  21. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 21, imagen 1 de 2 iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 21, imagen 2 de 2
    • With the corner of a plastic opening tool, gently move the ribbon cable out of the way so you can get to the screw beneath it.

    • You do not need to bend or rip the cable, just move it enough to access the screw.

  22. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 22, imagen 1 de 1
    • Remove the two 2.0 mm Phillips screws securing the power button assembly to the rear panel assembly.

  23. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 23, imagen 1 de 2 iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 23, imagen 2 de 2
    • Use the edge of a plastic opening tool to peel the piece of copper tape covering the volume/power button assembly.

    • LIft and remove the piece of copper tape out of the Touch.

  24. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 24, imagen 1 de 2 iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 24, imagen 2 de 2
    • Slide the plastic opening tool under the length of the ribbon cable to release it from the rear panel.

  25. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 25, imagen 1 de 1
    • Wedge the plastic opening tool under each volume controller and pry the assembly loose from the case.

  26. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 26, imagen 1 de 1
    • Flip the logic board/battery assembly over to access the ribbon cable solder joints.

    • In the next few steps, you will desolder the four volume/power button ribbon cable solder joints on the logic board.

  27. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 27, imagen 1 de 2 iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 27, imagen 2 de 2
    • The volume/power button cable is attached via solder pads with small holes that go through the cable and attach to flat pads on the face of the logic board. In this step, you will heat each solder pad individually while using a metal spudger to pry it up from the logic board.

    • DO NOT bridge the connection between the solder pads both on the board and on the ribbon cable with your spudger. Shorts have the potential to ruin the logic board.

    • Beware of overheating the board and the cable. Only hold the tip of the iron against the pad long enough to let the solder melt. Excess heat buildup has the potential to ruin the logic board or melt the ribbon cable.

    • Start working from the outside of the ribbon cable. Heat the outermost solder pad while gently prying up from under the ribbon cable to free it from the board. Repeat this process for each of the three remaining pads, working from right to left.

  28. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 28, imagen 1 de 1
    • At this point, the cable should be free from the logic board.

    • Lift the old cable out of the Touch and set it aside.

    • Place the replacement cable in place and align the far right contact with the far right solder point. Use two small strips of electrical tape to hold the cable against the solder pads.

    • Place two strips of tape over the end of the ribbon cable to both cover the two left-most solder pads and hold the contacts down against the logic board.

    • Heat the right-most contact until the solder below melts, then apply a small amount of solder to the contact, allowing it to flow through the two holes in the cable and down to the logic board.

    • Do not apply too much solder. The amount required for a proper bond is miniscule.

    • As soon as the solder has flowed into the joint, remove both the solder and the iron.

    • Repeat this process with the second solder pad.

  30. iPod Touch 4th Generation Volume/Power Button Cable Replacement: paso 30, imagen 1 de 1
    • Remove the old tape, and place a new piece of tape to hold the cable in place, but uncover the remaining two pads. If you are satisfied with the position of the cable relative to the pads on the board, proceed. If not, de-solder the first connection and try again.

    • Solder the two remaining pads to the logic board, being mindful of overheating the cable or board.
