LCD / Digitizer Screen Installation


Test the LCD / Digitizer Screen BEFORE installing/closing up device

Steps to follow:
    IMPORTANT: Make sure your phone is charged
  • Do not remove protective screen film/ cover
  • Attach the flex cable from the new LCD or digitizer screen to your phone or tablet.
  • Ensure the flex cables are seated correctly with a "clicking sound". Start at one end of the connector and use a gentle rocking motion while you work your way to the other end. (IMPORTANT: DO NOT BEND - CABLE IS VERY FRAGILE)
  • WARNING - Do not press the left and upper corners of the screen, otherwise it may cause lines on the screen.
  • Attach original home button and power on your phone or tablet
  • Test if the image and touch screen (all letters) are working. Run for 10 minutes.
  • If failure - clean connectors with 99% alcohol and repeat steps described above.

Damaged or defective items must be reported within 72 hours of receipt of order. Once installation begins, removing the screen's protective film and/or applying adhesive will void returns, refunds, and exchanges.

Set Up / Preparation


  • Watch a few repair videos and read our Quick Start guide before starting the repair. Repair Videos »

  • Have a PC or another phone to watch video while doing repair

  • Take your time - Allow 1-2 hours for repair and be patient. Most mistakes are caused by rushing through steps.

  • Back up your device via iCloud or iTunes before proceeding

  • IMPORTANT: Confirm the phone is powered off before starting repair AND disconnect your battery after it is open.

  • We recommend discharge your device battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured during repair.

  • Additional household items that will help to have on hand:
    • Scotch tape - helpful to hold together if cracked or shattered glass screen and help the suction cup stick
    • Hair dryer or heat gun - to loosen adhesive that hold screen in case
    • Playing card or credit card/ Razor blade / Exacto knife - to help lift out screen and cut through adhesive



Opening Device

The screen is held in place by strong glue. Apply heat to the edges, using either a hair dryer or a heat gun. The heat must be directed at the edges of the glass until it starts to loosen. Once the adhesive loosens, slide the plastic prying tool (or playing card/razor blade/ exacto knife) between the top of the glass and the frame of the phone. Insert the picks as you go to keep the screen separated. This may take a few attempts so be patient.

After clearing adhesive, DON'T OPEN all the way. To protect the delicate flex cable, make sure the angle between screen and body is less than 90 degrees.




Treat Flex Cables Gently - Very Fragile

  • Use tools instead of your finger during the installation. Otherwise, it will damage the screen!
  • Check for any dust or debris in between the flex cables and motherboard. Clear it with a brush or an alcohol dipped cloth.
  • Make sure the flex cables are properly connected with a “clicking” sound. Start at one end of the connector and use a gentle rocking motion while you work your way to the other end.
  • IMPORTANT: Don't bend the flex cables.
  • WARNING - Don’t force the connectors together until they are properly lined up. If a part doesn't fit quite right, don't force it. Take a step back and see if something's out of place such as a loose screw that's been magnetized to an ear speaker.


Using Repair Tools

  • Review how to use tools in Repair Tool Kit - here. Note there may be a few tools that do the same thing and a video might use a different one.
  • The tool kit includes different screwdriver heads and it is important to use the right one as to not strip the screw heads. NEVER over-torque a screw, it can easily damage something else or get stripped and stuck.


Stay Organized - Tiny Screws

  • Many screws will be removed and then re-installed. Screws are of different size and length. Mark each screw in order that you remove and related assembly with a number so that you can recognize them easily. If you put a screw into the wrong spot, your phone could be damaged.

  • Keep all pieces organized and numbered and work on a well lit WHITE paper base (like a sheet of paper or paper towel) so that you can see any little pieces that might go missing.


Static Free, Clean Environment

  • Make sure you have a nice clean space to work in with minimal distractions. A room that's not carpeted would be ideal. Make sure to be careful and minimize static electricity which can damage your device.
  • Use proper grounding techniques such as wearing an anti-static wrist strap (available in our store) or touch a steel table leg to discharge any static before starting work on anything. Static electricity can cause lines on your screen if not discharged.
  • If possible, use latex gloves or work on rubber mat, one designed for anti-static or just a household table place mat.
Note: If you have to reinstall the LCD more than once, when you connect the flex cable to the motherboard the second time static will be generated. If you get static lines on display, it will take 30 minutes to completely clear the static electricity on the screen after reconnected, since it is a capacitive touchscreen.



Disassembly Tips


Be Careful Transfering the Home Button

  • Don’t apply too much pressure to unglue the home button assembly (home button, home flex cable and home button aperture) from your original screen, for there is a lay of dust-proof tape around the home button. This is one of the most challenging parts of the repair. Be patient.

Disconnect Cables Gently

  • On iPhone, gently separate the LCD flex cable from the body, as it can be glued to the front glass lens.
  • Flex cables are fragile! Be careful when reconnecting to the logic board. Hold the bottom part of the flex cable ribbon with one hand, and then slightly bend the flex with the other hand. Keep holding and supporting the flex cable while reconnecting so it doesn't tear.

    A slight noise shows the LCD display screen flex cable and motherboard connected properly. Rough operation or mishandling may result in series problems such as touch screen and home button no response, static line, digitizer defect, screen shinning etc.

  • Be sure of that there are no dust and dots on the camera lens before installing the front-facing camera.
  • In the end, be sure the LCD display screen assembly is properly aligned with the top edge.
  • Protective Film

  • Most screens come with a protective film to guard against scratches. DON'T remove this until the new part is secured in the phone. The glass screen attracts dust and fingerprints and the protective film will help reduce this.
  • Make sure to remove the red/purple static protection sheet from the metal on the back of the LCD (using small tab sticking out).

  • Check Functions

    Before completing repair and closing up phone, test all functions by powering it on and checking the following:
    • Power button
    • Mute switch
    • Volume up/down
    • Digitizer/ Touch
    • Display and Light
    • Camera - Front and Rear
    • Microphone
    • Charging Port
    • WiFi and Cell signal
