Step-by-Step Fingerprint Flex Replacement Guide
Step 1. Power Off the Device
Always turn off your phone before starting any repair to avoid electrical damage or accidental short circuits.
Step 2. Heat the Back Cover
The back cover is secured with adhesive, so it must be softened first.
- Place it on a heating pad (back side down)
- Select the mobile heating option
Alternative:
Use a heat gun or hairdryer to warm the edges evenly.
Step 3. Remove the Back Cover
Once the adhesive is softened:
- Use a suction cup to create a small gap
- Insert a plastic pry tool or card
- Slide around the edges to separate the adhesive
Lift off the back cover carefully and place it aside.
Step 4. Remove the Midframe
- Eject and remove the SIM tray
- Unscrew all 17 screws securing the midframe
- Use a plastic tool to release all surrounding clips
- Lift the midframe gently from the device
Step 5. Disconnect the Battery & Fingerprint Plug
For safety and to prevent accidental shorting:
- Disconnect the battery connector
- Disconnect the fingerprint sensor connector
This isolates the components for safe removal.
Step 6. Remove the Faulty Fingerprint Flex Cable
- Locate the fingerprint flex near the midframe area
- Carefully lift the adhesive securing the flex
- Remove the damaged fingerprint flex cable from its slot
Step 7. Install the New Fingerprint Flex
- Place the new fingerprint flex into its correct position
- Apply light pressure so the adhesive bonds properly
- Ensure the cable sits flat, without bends or twists
Step 8. Reconnect Battery & Fingerprint Connectors
Reconnect:
- The fingerprint flex plug
- The battery connector
Check that both are firmly seated.
Step 9. Reinstall the Midframe
- Align the midframe with the device
- Ensure all clips snap securely
- Reinstall all 17 screws
- Insert the SIM tray back in place
Step 10. Close the Back Cover
Check the adhesive:
- If it’s still strong, press the back cover into position
- If weak, apply B7000 glue or new double-sided adhesive
Use binding clips or rubber bands to maintain pressure while the adhesive cures.
