Preparation

Start by adding the battery to the camera and powering it on.
Download the latest app onto your device and connect it to the camera.
Update your camera to the latest available firmware.
Test your camera's functionality before proceeding with disassembly.

Disassembly Steps

Step - Remove the Display

Remove the battery from the camera.
Use a cutter knife to slide along the seam of the back display. Adding heat with a heat gun can make this step easier.
Gently lift the display from the main body of the camera. The flat ribbon cable connecting the back display to the motherboard is still connected.

Step - Remove the Battery Bay

Remove the tape covering the screws in the battery bay. Alternatively, you can poke holes with a screwdriver to access the screws.
Use a PH0 screwdriver to remove the three screws from the battery bay.
Lift and remove the battery bay.

Step - Disconnect Ribbon Cables

Remove all flat ribbon cables from the motherboard. These connectors are secured with hot glue.
Heat the glue with a hot air gun and remove it carefully with a plastic tool.
Gently lift the connectors with a plastic tool to unplug them. Repeat for all five connectors.

Step - Remove USB Port and LED

Use a PH0 screwdriver to remove the two screws from the USB port. Lift the USB port with tweezers.
Remove the two screws from the back LED on top of the lens with a PH0 screwdriver.
Fold up the latch to access the spring and remove it with pliers.

Step - Remove Lens

Remove the single screw in the top left corner with a PH0 screwdriver. Pull up the heatsink with the LED flex cable.
Remove the two screws from the metal cable clip holding the lens cable connector.
Unplug the lens ribbon cable with a plastic tool.
Remove the four screws holding the lens in place with a PH0 screwdriver and lift the lens assembly.

Step - Disassemble Mainboard

Remove the top button cable connector with a plastic tool, heating the parts if necessary.
Remove the two black screws holding the motherboard with a PH0 screwdriver. Pry out the motherboard with a plastic tool.
Remove the three silver screws holding the motherboard holder with a PH0 screwdriver.
Unscrew the lens protector on the front side.

Step - Remove the Motherboard Holder

Pry out the motherboard holder using pliers, heating the case to ease removal.
Break off the two noses from the motherboard holder as they are too long for the naked version.

Step - Front Display

Heat the front display and press it out towards the front using the provided 3D-printed square tool.

Assembly Steps

Step - Install Thread Inserts

Press the thread inserts into the outer side of the naked case using a clean soldering iron set to 220°C.
Use 3x M2*4mm and 1x M2*3mm thread inserts, placing the 3mm insert in the marked position.

Step - Install Front Display

Glue the front display in place with 2K epoxy. Wait for the epoxy to cure.

Step - Attach ND Filter Adapter

Screw the aluminum ND filter adapter to the motherboard holder.

Step - Assemble Main Components

Place the motherboard holder into the naked action 4 front case and secure it with the three silver screws.
Screw an M1.6*6 screw through the top right hole and secure it with an M1.6 nut inside for additional strength.
Install the mainboard with the two black screws.
Install the lens and secure it with four lens screws.
Attach an ND filter to protect the lens during installation.

Step - Connect Cables

Connect the lens cable and front display cable to the mainboard. Ensure correct alignment before applying force.

Step - Install BEC Cable and Cooling Fan

Attach the bracket on top of the lens cable connector with the two screws.
Pry out the Naked Action 4 BEC cable from the foil and connect the three connectors to the motherboard.
Attach the cooling fan to the back case with M2*5 screws using an M2 hex tool.

Step - Final Assembly

Solder the fan's voltage and ground cables to the BEC's pre-tinned 5V and GND pads.
Connect the BEC flex cable to the BEC.
Place the BEC into the back case and screw the front and back cases together using 4x M1.6*8, 1x M1.6*12, and 1x M1.6*16 screws with a PH0 screwdriver. The longest 16mm screw goes in the top left corner, the 12mm screw in the bottom left, and the 8mm screws in the remaining holes.
