  1. 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.
    • 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.

  2. 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.
    • 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.

  3. When there is enough room to grab the bottom edge of the front panel, lift it away from the body of the Touch to peel up the adhesive along its left and right edges.
    • When there is enough room to grab the bottom edge of the front panel, lift it away from the body of the Touch to peel up the adhesive along its left and right edges.

    • If the adhesive is too difficult to separate, use a heat gun to soften it before proceeding.

  4. 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.

    • 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.

  29. At this point, the cable should be free from the logic board.
    • At this point, the cable should be free from the logic board.

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

  30. 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.

  31. 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.
