iFixit Home Button Replacement Manual

1. Introduction

This manual provides detailed instructions for replacing the home button on compatible iPhone models. This replacement part restores all home button functions, excluding Touch ID functionality.

For optimal results, it is recommended to have prior experience with small electronics repair or to seek professional assistance.

2. Safety Information

Please read and understand all safety precautions before beginning the repair process.

• Power Off Device: Always ensure your iPhone is completely powered off before starting any repair.
• Disconnect Battery: Disconnect the battery as early as possible in the repair process to prevent accidental short circuits.
• Static Discharge: Use an anti-static wrist strap or work on an anti-static mat to prevent electrostatic discharge (ESD), which can damage sensitive electronic components.
• Handle with Care: Electronic components are fragile. Handle them gently and avoid excessive force.
• Small Parts: Keep track of all screws and small parts. Using a magnetic mat or labeled containers is highly recommended.
• Eye Protection: Consider wearing eye protection to guard against small flying debris.
