This guide is for replacing the metal power and lock button cover, not the electronic switch itself.

Video Overview

  1. Before you begin, 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.
    • Before you begin, 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.

    • Your iPhone 4 rear cover may have either two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws (second image). Check which screws you have, and ensure you also have the correct screwdriver in order to remove them.

    • Remove the two 3.6 mm Pentalobe or Phillips #000 screws next to the dock connector.

    • Be sure the driver is well seated when removing Pentalobe screws, they are very easy to strip.

    • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.

  2. Push the rear panel toward the top edge of the iPhone. The panel will move about 2 mm.
    • Push the rear panel toward the top edge of the iPhone.

    • Some devices may have two screws, one of which holds down the contact pad which is located above the screw indicated in red in the photo.

  5. Use a plastic opening tool to gently pry the battery connector up from its socket on the logic board.
    • Use a plastic opening tool to gently pry the battery connector up from its socket on the logic board.

    • Pry from the top and bottom of the connector bracket—there isn't as much of an overhang on the sides, and you may damage the connector.

    • Be very careful to only pry up on the battery connector and not the socket on the logic board. If you pry up on the logic board socket, you may break it entirely.

    • Remove the metal clip covering the antenna connector.

  6. Use the clear plastic pull tab to gently lift the battery out of the iPhone. If the tab breaks before the battery is freed, carefully slide a spudger under the battery tab to release the adhesive. Prying in other places may cause damage. If your replacement battery came in a plastic sleeve, remove it before installation by pulling it away from the the ribbon cable.

    • If your replacement battery came in a plastic sleeve, remove it before installation by pulling it away from the the ribbon cable.

    • Before reconnecting the battery connector, be sure the contact clip (shown in red) is properly positioned next to the battery connector.

    • Before reassembly, clean metal-to-metal contact points with a de-greaser such as windex. The oils from your fingers have the potential to cause wireless interference issues.

    • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

  7. Use a SIM card eject tool or a paperclip to eject the SIM card and its holder. This may require a significant amount of force.

  14. Remove the following five screws securing the Wi-Fi antenna to the logic board:
    • Remove the following five screws securing the Wi-Fi antenna to the logic board:

    • One 2.3 mm Phillips

    • Two 1.6 mm Phillips

    • One 1.4 mm Phillips

    • One 4.8 mm Phillips

    • When re-assembling, start off with replacing the 4.8 mm Philips screw first, then the 2.3 mm. This is to ensure there is no mix-up, and avoid rendering the LCD and digitizer useless.

    • Also make sure to put the long 4.8 mm Philips back in correctly when reassembling. This is the ground for the Wi-Fi antenna and is often the culprit if you are having bad Wi-Fi reception after reassembly.

  15. Use an iPod opening tool to slightly lift the top edge of the Wi-Fi antenna away from the logic board. Use the tip of a spudger to pull the Wi-Fi retaining clips away from the inner frame. Remove the Wi-Fi antenna from the iPhone. Make sure you don't lose the metal clips on the top of the cover where the 4.8mm screw attaches or the 4.8mm screw. That's the primary reason for abnormal Wi-Fi performance after the reassembly.

  19. Remove the 4.8 mm standoff screw near the headphone jack.
    • Remove the 4.8 mm standoff screw near the headphone jack.

    • Standoff screws are best removed using an iPhone Standoff Screwdriver Bit and driver handle.

    • In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.

    • When reassembling the device, this standoff sets the height of the Wi-Fi shield removed in step 13. If not torqued down, the shield will be above the plane of the frame and the back will not slide into place in step 2. The shield should be flush with the headphone jack.

    • When reassembling the motherboard, ensure that its edge sits under the circled standoff, otherwise the screws will not fit.

    • When reassembling ensure that the small rubber spacer attached to the top of the motherboard is in place.

    • Without this part, the motherboard could damage the ribbon cables around it.

  20. Carefully remove the logic board from the iPhone, minding any cables that may get caught.

cant get the button to work it doesnt click when you press it the screws are tight and it just bends the middle of the plastic bit when you press it HELP PLEASE !!!

declan -

for that you need to take a look at the power and sensor cable (guide is on here as well). Either replace it or if you know what you are doing modify it.

Sebastian -

The guide was okay, until now!

Why isn't there shown how to install a new button?
