  1. If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass. Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered. This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

  2. Before you proceed, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you proceed, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.8 mm P2 Pentalobe screws on either side of the Lightning connector.

    • The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 5c that we recommend for anyone doing more than one repair on an iPhone 5, 5s, or 5c. If you aren't using the iSclack, skip to Step 5.

    • Close the handle on the iSclack, opening the suction-cup jaws.

    • Place the bottom of your iPhone in between the suction cups, against the plastic depth gauge.

      • The top suction cup should rest just above the home button.

    • Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.

  3. Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case. The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage any cables.

    • Peel the two suction cups off your iPhone.

    • Skip the next three steps and continue on to Step 8.

  4. Press a suction cup onto the screen, just above the home button.
    • Press a suction cup onto the screen, just above the home button.

    • Be sure the cup is completely on the screen to get a tight seal.

  5. Make sure the suction cup is firmly attached to the front panel assembly. While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.
    • Make sure the suction cup is firmly attached to the front panel assembly.

    • While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

    • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

    • With a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while you pull up with the suction cup.

    • There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

  6. Pull the plastic nub to release the vacuum seal on the suction cup.
    • Pull the plastic nub to release the vacuum seal on the suction cup.

    • Remove the suction cup from the display assembly.

  7. Lift the home button end of the front panel up to gain access to the connectors near the top of the phone. Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.

    • Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.

      • In a pinch, you can use an unopened canned beverage to hold the display.

    • Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

  8. Remove the two 1.6 mm Phillips #000 screws securing the metal battery connector bracket to the logic board.

    • Use a spudger or a clean fingernail to gently pry the battery connector up from its socket on the logic board.

    • Be very careful to only pry up on the battery connector itself and not the socket on the logic board. If you pry up on the logic board socket or the board itself, you may destroy the socket or damage nearby components on the board.

  12. Remove the following  Phillips #000 screws securing the front panel assembly cable bracket to the logic board:
    • Remove the following Phillips #000 screws securing the front panel assembly cable bracket to the logic board:

      • Two 1.3 mm screws

      • One 1.7 mm screw

      • One 3.25 mm screw

    • It is especially important to keep track of your screws in this step for reassembly. Accidentally using the 3.25 mm screw or the 1.7 mm screw in the bottom right hole will result in significant damage to the logic board causing the phone to no longer boot properly.

    • Be careful not to over-tighten the screws. If they don't fit easily when you are securing them, they may be the wrong size—don't force them.

  13. Remove the front panel assembly cable bracket from the logic board.
    • Remove the front panel assembly cable bracket from the logic board.

    • Be sure to only pry up on the connector, and not on the socket on the logic board.

  15. Make sure the battery is disconnected before you disconnect or reconnect the cables in this step. Use a plastic opening tool or a fingernail to disconnect the LCD cable connector. The LCD and Digitizer connectors are on the same cable assembly, so prying the LCD connector up should disconnect both connectors. Double check that the two cables are fully disconnected before removing the display.

    • When reassembling your phone, the LCD cable may pop off its connector. A blank screen, or white lines on the display could be caused by a loose connection. Should this happen, reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery.

    • Remove the following screws securing the logic board to the rear case:

      • Two 2.3 mm Phillips screws

      • Three 2.7 mm standoff screws

        • Standoff screws are best removed with a standoff screwdriver or standoff driver bit. A small flathead screwdriver can also do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.

Would a logic board swap be easier than a battery swap between 2 iPhone 5C's? ?

Dylan Tran - 답글

A battery swap would be significantly easier! Here's the battery replacement guide. =)

Sam Lionheart -

While I was repairing my phone, I guess the part where I didn't go around was taking out the battery because it felt like it was the more fragile part. This was because I did not have the proper equipment to take it away. This guide was pretty helpful for me in reconnecting cables.

Anyway, I am bothered that as I took out the logic board, there was this golden thing that just slid out of place. It slid from the top portion of the phone, but I do not know where it was originally and I do not know how it was supposed to be placed. It looked like an open box of sorts (but only had 3 sides bent up) and had a hole in the middle. It would be great if anyone would know where it could be placed so I could put back my phone.
