Firmly holding the Gear, insert the flat side of the spudger at an angle to pry the back casing off of the device. Move the spudger along the sides of the Gear to completely detach the back and front components.
Pry the device open from the other side also if it does not fully disassemble from one side.
Locate the rectangular metal connector that attaches the camera to the Gear.
Use tweezers to gently lift and detach the metal plate of the connector.
When reassembling the Gear, reattach the camera connector by carefully aligning the metal plate and its pins to its original placement. Make sure it snaps in place to avoid improper connections and possible damage.
Using two spudgers, place the pointed tips at each end of the U-shaped snap ring located under where the home button assembly was.
Remove the snap ring by pushing down with both pointed objects on each side of the ring simultaneously, it should pop off.
Be careful not to lose the snap ring because it can be lost easily.
To replace the snap ring, rest it above the home button peg using tweezers so the open side rests on the peg. Then use the flat end of the spudger and push firmly down on the snap ring to snap it back onto the peg as shown in the last picture.
