Introduction

If your GameSir Nova 2 Lite controller’s bumpers are unresponsive, sticky, or broken, this guide will help you replace them and restore full functionality. Over time, the bumpers can wear out due to frequent use, accidental drops, or internal component damage.

Before you begin, make sure to power off the controller and disconnect it from any devices to avoid accidental shocks or damage during the repair.

Step 2

Insert an opening tool between the two halves to open the controller's casing.
You will feel several internal latches called “snap-fit connectors.”
Disconnect them by sliding the opening tool along the seam in the casing, applying continuous pressure.
Once you find a connector, apply increased pressure until you hear a snapping sound.
Repeat this process until all of the connectors are disconnected.
Separate the top and bottom of the controller case.

Step 3

Set aside the bottom half of the shell.
Position the controller so that the motherboard is visible.
Use the point of a spudger to push on alternating sides of the battery connector to "walk" it out of its socket.
If that doesn't work, use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.

Remove the battery from the controller.
