Description: Use this guide to replace a worn-out or dead...

Steps:

1. Power off your iPhone before beginning disassembly.
2. Remove the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

3. If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.
4. Measure 3 mm from the tip and mark the opening pick with a permanent marker.
5. You can also mark the other corners of the pick with different measurements.
6. Alternatively, tape a coin to a pick 3 mm from the tip.

7. If your iPhone has a cracked screen, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.
8. Lay overlapping strips of clear packing tape over the iPhone's screen until the whole face is covered.
9. Wear safety glasses to protect your eyes from any glass shaken free during the repair.
10. If you can't get the suction cup to stick in the next few steps, fold a strong piece of tape (such as duct tape) into a handle and lift the screen with that instead.
11. If all else fails, you can superglue the suction cup to the screen.

12. The next three steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down three steps for an alternate method.
13. For complete instructions on how to use the Anti-Clamp, check out this guide.
14. Pull the blue handle backwards to unlock the Anti-Clamp's arms.
15. Slide the arms over either the left or right edge of your iPhone.
16. Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.
17. Squeeze the cups together to apply suction to the desired area.
18. If you find that the surface of your iPhone is too slippery for the Anti-Clamp to hold onto, you can use tape to create a grippier surface.

19. Pull the blue handle forwards to lock the arms.
20. Turn the handle clockwise 360 degrees or until the cups start to stretch.
21. Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

22. Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.
23. Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.
24. For complete instructions on how to use a hair dryer, check out this guide.
25. Wait one minute to give the adhesive a chance to release and present an opening gap.
26. Insert an opening pick under the screen's plastic bezel when the Anti-Clamp creates a large enough gap.
27. If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.
28. Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.
29. Skip the next two steps.

30. If you're using a suction handle, follow the next two steps to loosen the screen.
31. Use a hair dryer or a heat gun to heat the bottom edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.
32. Never leave your hair dryer in one spot for an extended period of time.

33. Apply a suction handle to the bottom edge of the screen, while avoiding the very edge of the glass.
34. Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.
35. Insert an opening pick into the gap under the screen's plastic bezel.
36. The watertight adhesive holding the screen in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

37. Use a hair dryer to heat the right edge of the iPhone (the edge with the power button) for 90 seconds or until the screen is slightly too hot to touch.

38. Slide the opening pick around the bottom right corner of the iPhone to separate its adhesive.
39. Continue sliding up the right edge of the iPhone until you reach the top right corner.
40. Don't insert your pick more than 3 mm, as you may damage internal components.
41. Leave the pick in the top right corner before continuing.

42. Use a hair dryer to heat the top edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

43. Slide the opening pick around the top right corner of the iPhone to separate the top adhesive.
44. Don't insert your pick more than 3 mm, as you may damage the top sensors.
45. Leave the pick in the top left corner before continuing.

46. Use a hair dryer to heat the left edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

47. There are delicate cables along the left edge of your iPhone. Don't insert your pick here, as you may damage the cables.

48. The cables along the left edge are very easy to damage with a pick. Follow this alternate procedure to separate the left adhesive.
49. Insert a second opening pick in the bottom left corner of the iPhone.
50. Twist both picks simultaneously until the left edge clips release.
51. Apply the twisting force gradually.
52. If you're having trouble separating the adhesive, reheat the left edge.

53. Remove your suction handle from the screen.
54. Rotate your iPhone so the right edge faces you.
55. Open your iPhone by swinging the screen up from the right side, like the front cover of a book.
56. Lean the screen against something to keep it propped up while you're working on the phone.
57. If you don't have anything at hand to lean the screen against, your suction handle can do the trick.
58. During reassembly, lay the screen in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the screen down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the screen and make sure they aren't bent.

59. Use a Y000 screwdriver to remove the eight screws securing the battery connector cover:
60. Five 1.3 mm-long screws
61. Two 1.6 mm-long screw
62. One 1.9 mm-long screw
63. Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.
64. During reassembly, this is a good point to power on your iPhone and test all functions before you seal the screen in place. Be sure to power your iPhone back down completely before you continue working.

65. Grasp the connector cover with a pair of tweezers and slide it downwards to clear the flex cables.
66. Remove the connector cover.

67. Use the pointed end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.
68. Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.
69. Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

70. Use the pointed end of a spudger to disconnect the first display cable by prying the connector straight up from its socket.
71. To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

72. Use the pointed end of a spudger to disconnect the second display cable by prying the connector straight up from its socket.

73. Remove the screen.
74. Apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
75. During reassembly, pause here if you wish to replace the screen adhesives.

76. Use a Phillips #000 driver to remove the four 1.5 mm-long screws securing the loudspeaker.

77. Use the flat end of a spudger to pry up and loosen the loudspeaker from the bottom-right corner of the phone.

78. Use a pair of tweezers to grab the loudspeaker.
79. Tilt the loudspeaker to separate it from the adhesive-backed strip that leads to the Taptic Engine.
80. Remove the loudspeaker.
81. When reinstalling the loudspeaker, place it in its recess battery-side first to align it with the adhesive-backed strip.

82. Use a spudger to disconnect the Taptic Engine by prying the connector straight up from its socket.

83. Use a Phillips screwdriver to remove the two screws securing the Taptic Engine:
84. One 1.8 mm-long screw
85. One 2.1 mm-long screw
86. Use a standoff screwdriver to remove the 2.9 mm-long standoff screw securing the Taptic Engine.
87. Standoff screws are best removed using a dedicated standoff driver or driver bit. 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.

88. Use a pair of tweezers or your fingers to remove the Taptic Engine.

89. If your replacement part didn’t come with the plastic strip along the top of the Taptic Engine, you'll need to transfer it to your replacement part.
90. Use your fingers or a pair of tweezers to gently peel the adhesive-backed strip off of the Taptic Engine.

91. Three stretch-release adhesive strips secure the battery to the rear case—two on the bottom edge of the battery, and one on the top edge.
92. Each adhesive strip has a black pull-tab at the end, which is lightly adhered to the edge of the battery.
93. In the following steps, you'll pull each tab to slowly stretch out the adhesive underneath the battery. These "command-strip" style adhesives lose their stick when stretched, so you can remove the battery with ease.
94. If the strips break, don't panic! They don't always work as intended. Keep reading for tips on removing broken strips.

95. Caution: Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.
96. Use a pair of blunt-nosed tweezers to peel down the two battery adhesive pull-tabs along the bottom edge of the battery.

97. Grab the first pull-tab with your fingers or wrap it around a spudger and slowly pull it away from the battery, toward the bottom of the iPhone.
98. Pull hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.
99. Don't press down on the battery. Hold the iPhone firmly by its sides.
100. Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.
101. Pull at a low angle so the strip doesn't snag on the edge of the battery.
102. If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.
103. If any of the adhesive strips break off underneath the battery and can't be retrieved, try to remove the other strips, and then proceed as instructed below.

104. Grab the second pull-tab with your fingers or the center of a spudger and pull it away from the battery, toward the bottom of the iPhone.
105. Follow the same procedure as with the previous strip: don't press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.
106. If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.
107. If the adhesive breaks off underneath the battery and can't be retrieved, continue with the next step.

108. Use a pair of blunt-nosed tweezers and an opening pick to peel up the remaining battery adhesive pull-tab from the top edge of the battery.

109. Using the same procedure as before, slowly pull the top adhesive tab to remove it. Try not to snag the adhesive on anything.
110. Be careful not to fling the battery from the iPhone as the final adhesive strip comes out.
111. If you removed all the adhesive strips successfully, skip the next step.
112. Otherwise, continue with the next step below.

113. If you're still having trouble removing the battery, apply a few drops of high concentration (90% or higher) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).
114. Wait about one minute for the alcohol solution to weaken the adhesive.
115. Use an opening pick or the flat end of a spudger to gently lift the battery.
116. Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

117. Remove the battery.
118. Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard.
119. If there's any alcohol solution remaining in the phone, carefully wipe it off before installing your new battery.
120. If your new battery didn't come with adhesive preinstalled, refer to this guide for help replacing the adhesive strips.
121. Perform a force restart after reassembly. This can prevent several issues and simplify troubleshooting.
