iPhone 17 Pro Max Screen Replacement Guide (2025 Model) - Easy DIY for Self-Built Store

About iPhone 17 Pro Max (2025 Model)

Pre-Repair Safety & Preparation (Critical for DIY Success)

• Fully power off your iPhone 17 Pro Max. Hold the power button and volume down button simultaneously, then slide to power off—wait 2 minutes to drain residual power, preventing short circuits that could damage the logic board or new screen.
• Backup your data to iCloud or a computer. While screen replacement won’t erase data, accidental damage to internal components (such as the battery or logic board) could result in data loss. This step is especially important if your screen is unresponsive and you can’t access your device.
• Work in a clean, well-lit, static-free environment. Use an anti-static wrist strap connected to a grounded metal surface to discharge static electricity—static can damage sensitive components like the OLED panel and Face ID module.
• Place your iPhone on a soft, lint-free microfiber cloth or anti-scratch mat to prevent scratches on the aluminum frame (which is prone to scuffing) and the new screen. Avoid using abrasive surfaces that could damage the device’s finish.
• Avoid using metal tools directly on internal components or flex cables. Use plastic tools to pry and lift, as metal can scratch the logic board or cut delicate cables. Also, avoid using high-concentration alcohol (over 70%) on the frame, as it may cause discoloration.
• Do not overheat the device. The iPhone 17 Pro Max’s battery is sensitive to high temperatures; excessive heat can cause swelling or damage. Use low heat settings when softening adhesive.
• Gather all tools and replacement parts (including our store’s compatible iPhone 17 Pro Max screen assembly) before starting—interrupting the repair to find tools increases the risk of mistakes.

Step-by-Step iPhone 17 Pro Max Screen Replacement Instructions

Step 1: Remove the Bottom Edge Screws

1. Place your iPhone 17 Pro Max face up on the anti-scratch mat. Locate the two Pentalobe screws on the bottom edge, on either side of the charging port.
2. Use the Pentalobe P2 screwdriver to remove both screws. Place the screws in the screw organizer and label them “bottom edge” to avoid mixing them up with other screws.

Step 2: Soften Adhesive and Lift the Screen

1. Use a heat gun or hair dryer on the lowest heat setting (50-60°C) to heat the edges of the screen for 30-40 seconds. Move the heat source in a slow, circular motion to soften the adhesive securing the screen to the body. Avoid overheating the top edge (near the Face ID module) to prevent damage to the sensors.
2. Press the plastic suction cup firmly onto the bottom edge of the screen (avoid covering the charging port). Pull upward gently to create a small gap between the screen and the iPhone body.
3. Insert the flat end of a plastic spudger into the gap. Gently slide the spudger around the perimeter of the screen to cut through the adhesive. Take your time—the adhesive is strong, and forcing it can crack the screen or scratch the aluminum frame (which is prone to scuffing).
4. Once all edges are separated, lift the screen upward—do not fully remove it yet. The screen is still connected to the logic board via flex cables at the top (near the Face ID module).
5. Place a soft cloth or folded paper under the screen to prop it up at a 45-degree angle—this prevents tension on the flex cables and protects the Face ID sensors.

Step 3: Disconnect the Battery (Critical Step)

1. Locate the battery connector on the logic board (near the bottom of the device, under a small metal bracket secured by two Phillips screws).
2. Use the Phillips PH000 screwdriver to remove the two screws from the battery connector bracket. Place the screws and bracket in the screw organizer (label them “battery bracket”).
3. Use the pointed end of a plastic spudger to gently lift the battery flex cable connector straight up from the logic board. Do not pull the cable itself—only lift the connector. This step prevents short circuits while working on the screen cables.
4. Confirm the battery is disconnected by pressing the power button—no lights or sounds should occur. If the iPhone turns on, repeat this step to ensure the connector is fully detached.

Step 4: Disconnect Screen Flex Cables

1. Locate the screen flex cable cluster on the logic board (at the top, near the Face ID module). There are four main cables: OLED display cable, touch digitizer cable, Face ID sensor cable, and ambient light sensor cable—unique to the iPhone 17 Pro Max’s upgraded sensor system.
2. Use the Phillips PH000 screwdriver to remove the three screws securing the screen cable bracket. Lift the bracket off to access the cables.
3. Use a plastic spudger to gently lift each flex cable connector straight up, one by one. Start with the largest cable (OLED display), then the touch digitizer cable, Face ID cable, and ambient light sensor cable. Be extra careful with the Face ID cable—damage to this cable will disable Face ID functionality.
4. Avoid bending or twisting the flex cables—they are delicate and can tear easily. If the cables are stuck, use a small amount of 70% isopropyl alcohol to loosen the adhesive holding them in place.

Step 5: Remove the Old Screen Assembly

1. Once all flex cables are disconnected, lift the old screen assembly completely off the iPhone body. Set it aside—you may need to transfer the Face ID module or sensor bracket to the new screen if it’s not included (our store’s replacement screen includes all necessary components for plug-and-play installation).
2. Use a microfiber cloth and 70% isopropyl alcohol to clean the iPhone body’s edge, removing any residual adhesive or dust. Ensure the surface is clean and smooth—this helps the new adhesive bond properly and prevents the screen from lifting later.
3. Inspect the logic board and cable connectors for any damage or debris. If there’s dust, use a soft brush to gently remove it. Also, check for any signs of corrosion (especially if the device was exposed to water), as this can cause the new screen to malfunction.

Step 6: Prepare the New Screen Assembly (Our Store’s Product)

1. Unbox the new iPhone 17 Pro Max screen assembly from our store. Verify compatibility by checking the model number (it should match A2896, A2898, A2899, or A2900) and ensure it includes the OLED panel, touch digitizer, Face ID sensors, and pre-installed adhesive strips.
2. If the new screen does not include the Face ID module or ambient light sensor, carefully transfer these parts from the old screen to the new one using tweezers. Be gentle—these components are fragile and essential for Face ID and auto-brightness functionality.
3. Remove the protective film from the new screen’s surface and edges. Use a microfiber cloth to wipe away any dust or fingerprints—this ensures a clear, smudge-free display.
4. Peel the backing off the pre-cut adhesive strips (included with our store’s screen) and align them along the edge of the new screen. Ensure the adhesive is positioned correctly—misalignment can cause the screen to not seal properly or lift over time.

Step 7: Install the New Screen Assembly

1. Hold the new screen assembly at a 45-degree angle and align the flex cables with their connectors on the logic board. Gently lower the screen onto the iPhone body, ensuring the cables are not pinched or bent.
2. Reconnect the four flex cables to their respective connectors on the logic board. Press each connector firmly until it clicks into place—do not press on the middle of the connector to avoid bending pins, which can cause display issues (such as green tint, a common problem reported by some iPhone 17 Pro Max users).
3. Reinstall the screen cable bracket and tighten the three Phillips screws. Ensure the bracket is secure to protect the cables and prevent them from coming loose.
4. Reconnect the battery flex cable to the logic board. Press the connector straight down until it’s fully seated, then reinstall the battery bracket and tighten the two Phillips screws.

Step 8: Seal the Screen and Reassemble

1. Carefully lower the new screen onto the iPhone body, aligning it evenly with the edges. Press firmly around the perimeter to secure the adhesive—start from the top (near Face ID) and work your way around to ensure a tight seal. Pay extra attention to the bottom edge, as this area is prone to lifting.
2. Use a clean microfiber cloth to press down on the edges for 1-2 minutes, helping the adhesive bond properly. Avoid pressing on the center of the screen, as this can damage the OLED panel or cause pixel distortion.
3. If there’s any excess adhesive, use a plastic spudger and 70% isopropyl alcohol to gently remove it. Do not use metal tools, as they can scratch the screen or aluminum frame.
4. Reinstall the two Pentalobe screws on the bottom edge using the Pentalobe P2 screwdriver. Tighten them evenly to ensure the screen is secure.

Step 9: Test the New Screen and Functions

1. Plug in the power adapter and press the power button to turn on your iPhone 17 Pro Max. Wait for it to boot up—this may take a few minutes, especially if it’s the first time turning on after screen replacement.
2. Once the iPhone is on, test the following functions to ensure the new screen is working properly (all functions should work seamlessly with our store’s replacement screen):
   1. Display brightness (adjust using the control center or Settings > Display & Brightness)
   2. Touch sensitivity (swipe, tap, and pinch to test all areas of the screen—ensure no unresponsive spots)
   3. ProMotion refresh rate (check in Settings > Display & Brightness > Refresh Rate—should support up to 120Hz)
   4. True Tone functionality (toggle on/off to test color accuracy)
   5. Face ID (unlock your iPhone and test Face ID recognition—ensure it works smoothly)
   6. Ambient light sensor (adjust room lighting to see if brightness changes automatically)
   7. Speaker and microphone (play music and record a voice memo to test)
   8. Charging port (plug in the charger to ensure it charges properly—no loose connections)
3. If the screen is unresponsive, flickering, has a green tint, or Face ID doesn’t work, power off the iPhone, disconnect the battery, and double-check all cable connections. Common issues include loose flex cables or misaligned connectors—easily fixed with a quick check.
4. Allow the adhesive to fully cure for 2-4 hours before using the iPhone normally—this ensures a secure seal and prevents the screen from lifting. Avoid putting the iPhone in a case or pressing on the edges during this time.
