- Safety first: Before starting any installation process, always make sure to disconnect the battery or power source to avoid any electrical mishaps or damage. This step is crucial for your personal safety and to prevent any potential damage to the device.
- Organize and keep track: When disassembling your device, it’s important to keep all the screws, parts, and accessories in a safe place. Use a magnetic mat or small containers to organize and label the different components. This will help you avoid losing any crucial parts and make the reassembly process much smoother.
- Mind the sharp tools: When replacing a cracked screen or using any sharp repair tools, exercise caution to avoid injury. Wear protective gloves and eyewear if necessary. Take your time and be gentle when handling the tools to prevent accidental cuts or damage to yourself or the device.
- Avoid touching the cameras: During the installation process, it’simportant to avoid touching the cameras located on the main board. Touching or damaging the cameras can disrupt their functionality, especially in devices equipped with Face ID technology. Handle the device carefully and focus on the specific task at hand without interfering with any other components.
- Remember, if you’re uncertain about any step of the installation process, it’s always a good idea to seek professional help or refer to manufacturer-provided guides.
Installation Steps:

If you have a severely cracked screen, you may have trouble mounting the suction cup.
You can combat this by covering the screen with tape and mounting the suction cup to the tape.
NOTE：If you’re struggling to create the gap, it might be due to the phone having cooled down. Heat the phone up and try again, the watertight adhesive holding the screen down is very strong so this may take time to slowly weaken the adhesive enough to create an opening.
