Anleitung

Before you begin
Vorsicht: Caution Allow your iPhone's battery to drain below 25%, as a charged lithium-ion battery is a potential safety hazard.

Unplug any cables from your iPhone.

Hold the power and either volume buttons, and slide to power off your iPhone.
Tape over any cracks
If your screen or back glass is badly cracked, lay overlapping strips of packing tape over the glass to protect yourself and make disassembly easier.

Hinweis: Note Make sure there's a smooth area near the bottom edge that's big enough for a suction cup to stick to.
Remove the pentalobe screws
Use a P2 pentalobe driver to remove the two 7.4 mm-long screws on either side of the charge port.
Mark your opening picks
Hinweis: Note If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.

Measure 3 mm from the tip and mark the opening pick with a permanent marker.

Hinweis: Note You can also mark the other corners of the pick with different measurements.

Hinweis: Note Alternatively, <a href="https://guide-images.cdn.ifixit.com/igi/pQGATIGUbViSB4gB.full" target="_blank">tape a coin to a pick</a> 3 mm from the tip.
Create a gap using a suction handle
Hinweis: Note The next two steps show how to create an initial gap using a suction handle.

Use a hair dryer or heat gun to heat the bottom edge of the back glass until it's hot to the touch.

Hinweis: Note You can also use an <a href="https://www.ifixit.com/en-eu/products/iopener?variant=31962085621841" target="_blank" class="product-link">iOpener</a> to heat the back glass. Follow <a href="https://www.ifixit.com/Guide/iOpener+Instructions/11677" target="_blank">these instructions</a> to heat and apply the iOpener properly.
Step 6
Apply a suction handle to the bottom edge of the back glass.

Pull up on the handle with strong, steady force to create a gap between the back glass and the frame.

Hinweis: Note If a gap doesn't appear, apply more heat to the edge and try again.

Insert the tip of an opening pick into the gap.
Back glass information
Vorsicht: Caution As you slice the adhesive securing the back glass in the following steps, don't insert your pick deeper than 3 mm to avoid damaging the following areas:

Heat the right edge
Use a hair dryer or heat gun to heat the right edge of the back glass until it's hot to the touch.
Separate the right adhesive
Vorsicht: Caution Don't insert your pick deeper than 3 mm to avoid damaging the spring contacts.

Insert a fourth opening pick into the bottom-right corner.

Slide the opening pick around the corner and up the right edge, stopping below the volume down button.

Leave this pick inserted to prevent the adhesive from resealing.
Reposition the back glass
Hinweis: Note At this point, the back glass should be free from the frame. If the back glass feels stuck, go back around the perimeter with your pick to check for missed sections of adhesive or stuck clips.

Swing open the back glass to the right of the iPhone to separate the remaining adhesive.

Support the back glass with a clean, sturdy object.

One 1.3 mm‑long screw

One 2.4 mm‑long screw
Step 49
Use your finger or a spudger to press the assembly cable connector onto the logic board.
Remove the leftover adhesive
Vorsicht: Caution Work around the fragile grounding clips as you're cleaning the frame. If you bend one out of place, gently bend it back with your fingers or tweezers.

Use blunt nose tweezers or your fingers to remove large pieces of adhesive from the frame perimeter.

Use a spudger to scrape the adhesive residue off of the frame.

Hinweis: Note If the adhesive feels stubborn, apply some heat using a <a href="https://www.ifixit.com/Guide/How+to+Use+a+Hair+Dryer+to+Soften+Adhesive/157348" target="_blank">hair dryer</a> or <a href="https://www.ifixit.com/Guide/How+to+Use+a+Heat+Gun+to+Soften+Adhesive/151116" target="_blank">heat gun</a> and try again.
Clean the back glass
If you're reusing your back glass, apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to a microfiber or lint-free cloth and wipe around the perimeter to prepare the surface for new adhesive.
Clean the frame
Wrap a lint-free cloth or a coffee filter over the point of a spudger and apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to it.

Wipe in one direction along the perimeter of the frame to clean the adhesive residue.

Hinweis: Note Take your time doing this. A clean frame allows replacement adhesive to lay evenly, ensuring a better bond.
Apply the replacement adhesive
Lay the adhesive sheet over the frame to determine its proper orientation.

Hinweis: Note Use features such as the camera cutout and notches along the top and bottom edges to visualize how the adhesive will lay in the frame.
Step 54
Grab the tab in the corner of the adhesive sheet and peel the liner to expose a third of the adhesive.

Vorsicht: Caution The exposed adhesive is very sticky. Don't let it touch anything until you're ready to apply it to the frame.

Hinweis: Note If your adhesive has multiple liners, peel the liner that exposes the side that sticks to the frame.
Step 55
Carefully align the exposed edge of the adhesive strip with the corresponding edge of the iPhone's frame.

Vorsicht: Caution Once the adhesive is pressed into place, you can't reposition it—you'll have to remove it and start over with new adhesive.

When it's correctly aligned, gently press the exposed adhesive strip onto the frame.
Step 56
Continue peeling away the liner from the adhesive, gently pressing the adhesive into place.

Hinweis: Note If you've correctly aligned the adhesive, the edges will fall perfectly into place.

Hinweis: Note If your adhesive is slightly misaligned, gently pull the long edges into alignment with the frame.

Hinweis: Note If the adhesive begins to crease or wrinkle, remove it and start over with fresh adhesive.

Hinweis: Note If you don't have another set of adhesive strips handy, it's okay to temporarily put your iPhone back together and use it normally without any adhesive. Just keep in mind that your iPhone's water resistance will be compromised until you replace the adhesive.
Step 57
Use a spudger to press the adhesive around the entire perimeter of your iPhone.

Vorsicht: Caution Work around the fragile grounding clips. If you bend one out of place, gently bend it back with your fingers or tweezers.

Hinweis: Note Don't press too hard, or you'll stretch and deform the adhesive.
Step 58
Use a spudger or your fingers to lift the pull tab connected to the large front liner. The pull tab is often in a corner of the liner.

Use the pull tab to peel off the large front liner from the adhesive.

Hinweis: Note At this point, you may still have a liner covering the perimeter, which prevents the adhesive from accidentally sticking to anything while you're reassembling your iPhone. Don't remove these small release liners just yet.
Connect the back glass
Prop up the back glass along the right edge of your iPhone.
Step 60
Use your finger or the flat end of a spudger to press and connect the back glass connector onto the logic board.
Connect the battery
Use your finger or a spudger to press and connect the battery press connector onto the logic board.

Hinweis: Note This is a good point to test your repair before sealing up your iPhone. Power on your iPhone and make sure it works as expected. Power it back down and continue reassembly.

Hinweis: Note If your iPhone doesn't turn on, connect it to a power source and try again.

Hinweis: Note If you've replaced the logic board and the screen fails to turn on, you'll need to follow the <a href="https://www.ifixit.com/Guide/iPhone+16+Pro+Max+Screen+Replacement/178634" target="_blank">screen guide</a> to manually connect the display connector.
Install the connector covers
Align the back glass connector cover by its screw holes and lay it in place.
Step 63
Use a tri-point Y000 driver to install the four screws securing the back glass connector cover:

Two 1.3 mm‑long screws

Two 1.0 mm‑long screws
Step 64
Align the battery connector cover by its screw holes and lay it in place.
Step 65
Use a tri-point Y000 driver to install the three screws securing the battery connector cover:

Two 1.3 mm‑long screws

One 1.0 mm‑long screw
Remove the final adhesive liners
Use your fingers or a spudger to peel away all perimeter liners, exposing the adhesive.

Hinweis: Note As you remove the liners, make sure nothing touches the exposed adhesive.

Check the frame and back glass for any stray liners and remove them. There should be no liners remaining.
Install the back glass
Lower the back glass onto the frame, beginning with the top edge.

Vorsicht: Caution If you feel resistance, a perimeter clip may have bent out of place and is being crushed by the frame. Look at the point of resistance and gently straighten any bent clips.

Press along the edges of the iPhone until the back glass sits flush against the frame.
Apply heat to the perimeter
Use a hair dryer, heat gun, or an iOpener to heat the back glass perimeter until it's slightly too hot to touch.

Hinweis: Note The heat softens the adhesive and helps create a better bond.
Apply pressure to the perimeter
Use your fingers to firmly squeeze around the perimeter of the iPhone.
Step 70
Place your iPhone screen-side down on a clean, flat work surface.

Lay a strip of tape around the perimeter of the back glass to protect the finish.

Stack coins around the perimeter of the back glass until you create a wall that's as tall as the rear camera protrusions.

Hinweis: Note Alternatively, you can use <a href="https://www.ifixit.com/Guide/How+To+Use+Screen+Vise+Clamps/142291">vise clamps</a> around the perimeter of your device to set the new adhesive.
Step 71
Place 3-4 heavy books squarely on top of your iPhone.

Vorsicht: Caution The coins may leave a slight impression on the bottom book cover, so don't use anything valuable.

Leave the books in place for about 30 minutes.

Hinweis: Note The pressure will help activate the adhesive.
Install the pentalobe screws
Use a P2 pentalobe driver to install the two 7.4 mm-long screws on either side of the charge port.
