In modern life, iPhone has become an indispensable electronic device for many people. With frequent use, it is inevitable that the iPhone's back glass will be broken due to dropping or other external factors. Once the iPhone back glass is damaged, many people will choose to replace it by themselves. The following will detail the steps to remove and replace the iPhone back cover glass and the tools required.
I. Preparing Materials
Before carrying out iPhone back cover glass replacement, you first need to prepare the following tools and materials:
- New iPhone back glass: make sure you purchase the original or a high-quality replacement to ensure compatibility and durability.
Pentagonal screwdriver: used to unscrew the two fixing screws on the bottom of the iPhone.
Triangular screwdriver: used to loosen the fixing screws of the battery connector.
Suction cup: Helps to attach and detach the back cover glass.
Cocking piece or plastic card: used to gently pry open the gap between the back cover and the body.
Hair dryer or heat gun (optional): to heat the edges of the back cover to soften the glue for easy removal.
II. Detailed Steps
1. Switch off the device and disconnect the power
Step-by-step instructions: Before performing any repair operations, make sure the iPhone is completely turned off and all cables are unplugged. This is to ensure the safety of the device as well as to avoid short circuits or other accidents during disassembly.
IMPORTANT: Disconnecting the power prevents damage to the circuitry or risk of electric shock during disassembly and safeguards the user and the device.
2. Remove the bottom screws
Step-by-step instructions: Use a pentagonal screwdriver to unscrew the two screws on the bottom of the iPhone. These two screws are usually located on either side of the charging port and are a key part of the back cover that holds it in place.
-Important: These screws are one of the main components that hold the back cover in place and must be carefully unscrewed and stored in a safe place for later reinstallation.
3. Suction and carefully pry off the back cover
Step-by-step instructions: Use a suction cup to attach to the back cover and gently pull up to create a gap. Then, insert a plastic pry bar or credit card and slide it slowly and carefully along the gap to further separate the back cover from the body. It is important to note that the force should be applied gently and evenly to avoid over-exerting yourself and causing the back cover to break.
IMPORTANT: This step is critical as it determines whether the back cover will be removed intact. If not done properly, it may damage the back cover or even the internal structure of the body.
4. Disconnecting the Battery
Step-by-step instructions: Locate the battery connector and use a triangular screwdriver to unscrew the screws holding it in place. Then, carefully disconnect the battery from the motherboard.
IMPORTANT: Disconnecting the battery is to ensure that a short circuit does not occur during disassembly and also to prevent accidental electric shock.
5. Remove the broken back cover glass
Step-by-step instructions: After confirming that all connections have been disconnected, gently remove the broken back cover glass. If you encounter sections that are difficult to remove, you can use tools such as tweezers and a small spatula to assist in cleaning up the broken glass residue.
IMPORTANT: It is very important to thoroughly clean up old back cover glass debris as they may affect the installation of the new back cover and may even scratch other parts.
6. Cleaning up adhesive residue
Step-by-step instructions: Use alcohol or other cleaners to clean up any old glue residue left on the body. Make sure the surface is clean and dust-free so that the new back cover can be firmly affixed.
IMPORTANT: Whether the cleaning is done thoroughly or not directly affects the quality of the new back cover installation. If the residual glue is not removed, it may cause the new back cover not to be properly attached.
7. Installing the new back cover glass
Step-by-step instructions: Align the new back glass with the iPhone body and press it slowly from one side until it fits perfectly. Make sure to align all edges without leaving bubbles or gaps. For new back covers with camera holes, special care also needs to be taken to align the camera position.
IMPORTANT: Properly installing the new back cover is the last and most critical step of the entire restoration process. Only when the new back cover is securely installed on the body can its sealing and aesthetics be guaranteed.
8. Reconnect the battery and tighten the bottom screws
Step-by-step instructions: Reconnect the battery in reverse order and tighten the bottom screws. Ensure that the battery connector is securely inserted into place and that the screws are not overtightened to avoid damaging the threads.
IMPORTANT: Reconnecting the battery is a necessary step to restore the functionality of the device, while tightening the screws ensures the stability and security of the back cover.
9. Testing the device
Step-by-step instructions: After completing all the above steps, switch on your iPhone to check if it is working properly. Test the functions such as screen display, touch response, speakers and microphone to see if they are working properly.
Importance: The final function test is essential to help us confirm whether the replacement device is back to its normal working condition and whether there are any potential problems that need to be resolved.
III. Precautions
During the whole replacement process, there are some key points that need special attention:
When using a hair dryer or heat gun to heat the edge of the back cover, be careful that the temperature should not be too high to avoid damaging the internal components. It is recommended to use a low gear and keep a certain distance to avoid direct high temperature contact.
When separating the back cover from the body, a gentle force should always be used to avoid violent operations that could lead to more breakage or deformation. Caution is needed especially for first-timers.
- Replacing the back cover glass is a delicate job that requires patience and skill. If you are not confident enough in your do-it-yourself ability or are worried about damaging your device, it is best to seek professional help to complete the job.
In a nutshell, with the above detailed steps, I believe you have already mastered how to replace the iPhone back glass on your own. However, considering the many technical details involved and the risks involved, it is recommended that you try DIY repair with enough confidence or choose a professional repair service to ensure safety and quality.
