If your iPhone 13 screen is cracked, not responding to touch, or not showing a picture when your phone is powered on, use this repair guide to restore your iPhone to working order with a new screen

 

Important information before replacing the display

 

1. Drain the iPhone to below 25% as a fully charged Li-ion battery can catch fire or explode if its protective layers are accidentally breached.

 

2. The combined earpiece speaker + sensor assembly attached to the back of the display is factory paired with your individual iPhone, so you must transfer it from the old display to the new one during any display replacement. It includes a flood illuminator, which is part of the biometric security feature Face ID.

 

3. If Face ID is damaged or replaced, it will stop working, so be careful not to damage any of these components during this procedure. In case of damage, only Apple or an Apple authorized technician can restore the Apple ID function.

 

4. Opening your iPhone will breach its water-resistant seal, so have a replacement seal ready before starting this repair. Without a new seal, your iPhone will not be water-resistant, and there's a higher likelihood of dust or moisture ingress.

 

5. Wear protective glasses to prevent eye injury during the repair.

 

6. Organize screws during the repair to prevent mixing them up, which could lead to damage to the iPhone by using the wrong screw in a thread.

 

7. The True Tone feature is disabled after a screen replacement, even when using an original Apple screen. Additionally, your iPhone may temporarily display a warning about the "authenticity" of the display.

 

8. After replacing the display, a message "Important Message" will be displayed on the screen.

 

    • The message simply informs that the original display has been replaced with a new one.

 

    • The message has no impact on the device's performance.

 

    • It appears on the lock screen for 4 days, then in the settings.

 

This is caused by the display replacement not being authorized by Apple's official software, and the part was not paired with the motherboard.

 

Apple trying to achieve to ensure that users have their devices repaired at authorized service centers, which use original Apple parts, accessories, and software.

 

Tips for Getting Started

 

Highlight 3 mm on the pick or card.

 

Do not insert the pick or card more than 3 mm, as you could damage internal components.

 

If your iPhone's display is cracked, cover it with adhesive tape to prevent injuries during the repair.

 

If you are unable to attach the suction cup in the following steps, use a strong piece of tape (such as duct tape) and lift the screen.

 

Do not put your iPhone in the microwave!!

 

Required Tools

 

New display for iPhone 13

LCD Adhesive

Heat pad

ESD gloves

Tool kit

Pentalobe screwdriver

Protective glasses

Heat gun

Suction cups / securing tool

Pick

Card

Spudger

Tweezers

Isopropyl alcohol

Cleaning cloth

Dust blower

Step 1
Unscrewing the bottom pentalobe screws

Before starting, it is necessary to discharge the iPhone below 25% because a charged Li-ion battery can ignite or explode if accidentally cut.

 

 

Opening iPhone will break its waterproof seal, so have a replacement seal ready before beginning this step. Without a new seal, your iPhone will not be waterproof.

Step 2
Display Disassembly

A) Heating the phone

 

1It is recommended to wear protective ESD gloves.

 

2Using a hair dryer or heat gun, heat the entire perimeter of the display for about 3 minutes to reach a temperature of approximately 80°C (176°F), or until it becomes difficult to keep your hand on the phone due to the high temperature.

 

Heating the phone helps to soften the adhesive between the display and the phone frame, making it easier to open.

Along the left edge of the iPhone are flex cables. Do not insert the pick or card into this side!

 

B) Opening the display

 

The display can be opened in two different ways: The first method is using a suction cup, and the second method is using a securing tool, which is safer.

In this guide, we will proceed using a suction cup.

 

Placement of the suction cup

 

  • Place the suction cups near the bottom edge of the iPhone, one on the front and the other on the back, and gently press down on the spot.
  • If using a single cup, attach it to the bottom edge of the phone, stay away from the edge of the glass.
  • Securely hold your iPhone and with firm, steady pressure, pull on the suction cup to create a gap between the frame and the display.
  •  

After separating the display about 3 mm from the frame, insert a pick or card into the gap.

The adhesive holding the display in place is very strong. Therefore, creating this initial gap requires considerable force. If you encounter difficulty, reheat the bottom edge and gently slide the display up and down repeatedly to weaken the adhesive until you create a gap large enough to insert the card.

 

C) Heating the right edge

 

  • Utilize a hair dryer or heat gun to warm up the right edge of the iPhone (the side with the power button) for approximately 90 seconds, or until the screen reaches a temperature too hot to touch

 

D) Separating the adhesive (right side of the iPhone)

 

  • Put the pick or card from the bottom right corner and slide it upwards to the top right corner, gently separating the adhesive as you go.

 

Exercise caution and avoid inserting the pick or card more than 3 mm to prevent any potential damage to internal components.

 

  • Before proceeding, leave the pick or card in the top right corner.

 

E) Top edge

 

  • Apply heat with the hair dryer or heat gun to the top edge of the iPhone for approximately 90 seconds, or until the screen reaches a temperature that is too hot to touch.
  • Use the pick or card to separate the adhesive around the top right corner of the iPhone

Before proceeding, leave the pick or card in this corner.

 

F) Heating the left edge

 

  • Apply heat the left edge of the iPhone with a hair dryer or heat gun for 90 seconds or until the screen becomes too hot to touch.

 

G) Separating the adhesive (left side of the iPhone)

 

  • Insert the pick or card into the bottom left corner of the iPhone.
  • Slide the pick or card along the entire edge until the clips holding the display release. Be careful of the flex cables located on this side of the display.

If you have difficulty separating the adhesive, reheat the left edge.

Step 3
Opening the iPhone

  • After successfully releasing the adhesive from the edges, remove the suction cup/s.
  • Open the iPhone by flipping the display to the left side (like a book).

It is recommended to support the display to avoid tearing the flat flex cable that connects the display to the motherboard.

Do not try to completely detach the display at this point, as there are several delicate flat flex cables still connecting it to the iPhone's motherboard.

Warning: If the battery is damaged stop the repair.

During the reassembly process, position the display correctly and align the clips along the top edge. Press the top edge carefully into place before firmly securing the rest of the display. If you encounter difficulty in securing it, examine the condition of the clips around the display perimeter to ensure they are not bent or damaged.

Step 4
Removing the battery and display connector cover

Step 5
Disconnecting the battery

  • Use the tip of a spudger tool to pry the battery connector off the motherboard.
  • Gently bend the battery connector with the flex cable away from the motherboard to prevent accidental contact with the motherboard connector and thus avoid potential short circuits.

Try not to damage the black silicone seal, which provides additional protection against water and dust ingress.

Step 6
Disconnecting the display

  • Disconnect the cable connector and digitizer using a spudger tool or your fingernail.

When assembling the iPhone back.

For reconnection, press down on the flex cable connector.

Follow these steps:

  • Carefully align and press down on one side of the flex cable connector until it snaps into place.
  • Then repeat this process on the other side of the flex cable connector.

 

Avoid pressing on the middle part of the flex cable connector. If the flex cable connector is improperly aligned, the pins on the flex cable connector or on the motherboard connector may bend and cause permanent damage.

Step 7
Dismounting the front sensor connector cover

Unscrew the three screws securing the front sensor connector cover:

One 1.7 mm Phillips screw

One 1.3 mm Phillips screw

One 1.8 mm Y000 screw

 

Carefully remove the cover because there is a small clip by the edge that is under the flex cable

Step 8
Disconnecting the front sensor connector

  • Disconnect the front sensor flex cable connector using a spudger tool or your fingernail.

Step 9
Disassembling the display

  • Remove the display assembly.

After removing the display, place it on a clean, straight surface.

Warning: Do not touch the TrueDepth camera, grounding springs or near parts.

Step 10
Unfasten adnd remove the front sensor bracket

With a Y000 screwdriver to unfasten three 1.4 mm screws holding the front sensor bracket.

 

  • With tweezers or fingernails remove the front sensor cover bracket.

Step 11
Heat the front sensor assembly

  • Use a heat gun or a hair dryer and apply it to the top edge of the screen.

Be careful not to overheat the display. It is vulnerable to heat damage.

Step 12
Disconnect the ambient light sensor

  • Insert an opening pick between the ambient light sensor and its recess in the screen. Pry up with the pick to separate the ambient light sensor from the screen.

Step 13
Disconnect the proximity sensor

  • Place an opening pick between the proximity sensor and its designated area on the screen. Apply gentle pressure to lift and separate the proximity sensor from the screen using the tool.

Step 14
Reposition the proximity sensor

  • Utilize tweezers or your fingertips to carefully reposition the proximity sensor cable, moving it away from the screen.

Step 15
Disconnect the microphone

  • Position an opening pick beneath the microphone cable, near the microphone itself (the metal rectangle).
  • Gently maneuver the opening tool around the edges of the microphone to loosen the adhesive and separate it from its position.

Step 16
Remove the front sensor assembly

  • If the adhesive has cooled, warm up the assembly with a heat gun or hair dryer for about one minute before proceeding.
  • Next, insert an opening pick under the left side of the front sensor assembly. Carefully slide the tool beneath the assembly to detach it from the frame.

Step 17
Transferring the assembly to a new screen

  • Connect the sensors to their designated slots in the frame to assist in aligning the main section of the assembly.
  • Then, use double sided tape to re-affix any parts of the assembly that have lost their adhesive properties.

Step 18
Removing old adhesive around the edges of the iPhone

  • Remove the old adhesive around the edges of the iPhone using the spudger tool.

  • Little bit of isopropyl alcohol can help you unstick the adhesive.

Step 19
Applying new adhesive around the edges of the display frame

  • Apply new adhesive around the edges of the iPhone. Reconnect the battery through the reverse process.

The new adhesive will ensure the iPhone's resistance to water and dust.

Before placing the new display on the iPhone make sure to remove the protective foil.

Opening your iPhone will breach its water-resistant seal, so have a replacement seal ready before starting this step. Without a new seal, your iPhone will not be water-resistant, and there's a higher likelihood of dust or moisture ingress.

Step 20
Reassembling the iPhone

  • Check the phone for excess screws and small parts that may be stuck in the body of phone and remove them.
  • Install the new display on your phone.

When reassembling the iPhone back to its original state, follow these instructions in reverse order.

After reassembly, perform a forced restart. This may help prevent some issues.
