Step-by-Step Power Button Flex Replacement
Step 1. Opening the Device
Turn off your OnePlus Nord N200 5G completely. Heat the edges of the back cover gently using a heating pad or hair dryer to soften the adhesive. Use a suction cup to create a gap and a plastic card to carefully lift the back cover.
Step 2. Removing the Midframe
Remove the SIM tray first. Unscrew all screws securing the midframe. Carefully pry up the midframe using a plastic tool to release all clips without damaging internal components.
Step 3. Disconnecting Battery and Fingerprint Plug
Before proceeding, disconnect the battery and fingerprint sensor connectors. This ensures safety and prevents short circuits during the repair.
Step 4. Removing the Battery
Loosen the adhesive securing the battery and lift it out gently. Take care not to bend or damage the battery during removal.
Step 5. Removing the Logic Board
Carefully remove the logic board to access the power button flex. Set it aside in a safe location to avoid bending or damaging connectors.
Step 6. Removing the Faulty Power Flex
Locate the defective power button flex cable and disconnect it from the logic board. Remove it carefully, taking care to avoid damage to surrounding components.
Step 7. Installing the New Power Flex
Place the new power button flex cable in the same position as the old one. Reconnect all connectors securely, ensuring proper alignment to restore full power button functionality.
Step 8. Reassembling the Device
Reinstall the logic board and verify all connectors are seated correctly. Place the battery back and reconnect the battery and fingerprint sensor plugs. Secure the midframe by pressing all clips into place and tightening all screws. Reinsert the SIM tray.
Step 9. Closing the Device
Check if the back cover adhesive is sufficient. Apply B7000 glue or a new double-sided adhesive if needed. Align the back cover carefully, press firmly, and secure it using binding clips or rubber bands. Leave to cure for proper adhesion.
