Essential Tools:

  • Pentalobe screwdriver (for iPhone bottom screws)
  • Tri-point or Phillips screwdriver (varies by model)
  • Plastic opening picks
  • Suction handle or screen removal suction cup
  • Spudger and tweezers
  • Plastic card or guitar pick (for prying)

Parts Needed:

  • Replacement screen (preferably OEM or Apple-certified)
  • Adhesive strips or sealant for reassembly
  • New waterproof gasket (if your iPhone is IP-rated)

If you’re replacing the screen through Apple’s official Self Service Repair Program, you’ll also receive a calibration tool that ensures your new screen is recognized by the iPhone’s firmware. This is especially helpful for newer models where part authentication is tied to software integrity.

Step-by-Step Guide to Replacing an iPhone Screen

Step 1: Power Down and Prepare

Begin by powering off your iPhone completely. This reduces the risk of shorting the board or damaging internal components. If possible, let the phone’s battery drain below 25% to minimize the chance of combustion during disassembly.

Step 2: Remove the Pentalobe Screws

Locate the two screws flanking the Lightning port at the bottom edge of your phone. Use a pentalobe screwdriver to remove them. These are your first barrier to entry and need to be stored safely.

Step 3: Soften the Adhesive

Use a heat source—preferably a heat pad or hair dryer—to warm the edges of the screen. This loosens the adhesive that seals the display, making the separation process smoother and less risky.

Step 4: Open the Device Carefully

Place a suction cup just above the home button (or center-bottom if your model doesn’t have one). Gently pull while inserting a plastic pick at the corner to wedge open a gap. Work your way around the edges, being cautious not to push in too far and damage internal flex cables.

Step 5: Disconnect the Battery

Before removing the screen entirely, disconnect the battery to prevent any power from flowing while you’re detaching connectors. Remove the metal shields covering the connectors, then carefully disconnect the battery using a spudger.

Step 6: Detach Display Flex Cables

Your screen is connected via multiple ribbon cables—usually for the display, digitizer, and front camera sensors. Disconnect these methodically. Some models have up to five connectors stacked tightly. Once detached, you can remove the screen completely.

Step 7: Transfer Components (If Required)

If your new screen doesn’t come pre-installed with parts like the earpiece speaker, front sensor array, or home button, you’ll need to carefully transfer them from the old screen. This is the trickiest part—especially for Face ID, which won’t function if damaged or misaligned.

Step 8: Reconnect and Reassemble

Connect the new screen’s flex cables to the motherboard, making sure each connector clicks into place. Reinstall the battery connector last. Reattach the protective shields and test the display for functionality before sealing it shut.

Step 9: Reseal the Phone

Apply a new adhesive seal (especially if waterproofing is a concern) and gently press the screen back into place. Secure the pentalobe screws and power the phone on. Check for dead spots, camera alignment, and any error messages.

Software Configuration and Calibration

On newer iPhones running iOS 18 and above, a post-repair calibration process is initiated via a built-in “Repair Assistant.” This tool helps the phone verify the authenticity of the new part and recalibrates the display to restore features like brightness control, Face ID, and color profiles. You’ll be guided through these steps during startup if required.

Skipping this process can result in permanent alerts, non-functional Face ID, or uncalibrated color tones—especially when using third-party screens. Using Apple’s official program or a certified repair shop ensures a smoother integration.

Important Considerations Before You Start

1. Your Warranty May Be Voided

If your iPhone is under warranty or covered by AppleCare+, attempting a DIY screen replacement may void that coverage. Apple can usually detect third-party repairs, even if they use genuine parts.

2. Face ID and Touch ID May Break

Both biometric systems are uniquely tied to the logic board. Damaging the cables or transplanting them incorrectly will disable Face ID or Touch ID permanently. Use extreme caution or avoid replacing the screen if you’re unsure.

3. Water Resistance Is Compromised

Once opened, your iPhone’s factory waterproofing is no longer guaranteed. Even with new adhesive seals, the original IP rating is hard to restore. If you live in a humid or rainy environment, weigh this risk seriously.

4. Tools Matter

Using cheap or incorrect tools can strip screws, puncture the battery, or tear connectors. Investing in a decent kit or renting one from Apple’s repair program (which includes torque-calibrated screwdrivers) can make all the difference.

Should You Replace the Screen Yourself?

If you’re tech-savvy, comfortable with delicate electronics, and understand the risks, replacing your iPhone screen yourself can save time and money. However, it’s not a task for everyone. Small mistakes can lead to expensive consequences—especially with newer models that are packed tighter than ever.

For most users, having the screen replaced by Apple or an authorized repair center remains the safest route. But for those who love to tinker or simply want to extend the life of their device, this guide gives you the most complete, up-to-date roadmap to success.
