Step 2: Disassembly

⚠ Make sure the batteries are removed before attempting disassembly.

Using your Phillips #1 screwdriver, remove the four visible 12.5mm screws.

Next, either peel up the longer of the two stickers or punch a hole with the tip of your screwdriver to access the fifth 12.5mm screw.

Step 3: Casing Separation

Once all five screws are removed, split the casing apart by applying gentle upwards pressure against the positive terminals in the battery compartment.

Step 5: USB Port Desoldering

Place the motherboard on a clean, flat surface.

Preheat your soldering iron. Each USB port has eight points of connection to the motherboard (pictured above). Using your soldering iron, apply heat to each solder joint in turn while pulling the USB port away from the board.

⚠ Soldering irons can reach temperatures of over 500 degrees. Watch your fingers!
