Instructions
Opening the GMMK PRO
1. Unplug your keyboard and keep it unplugged throughout this process.
2. Remove all switches, keycaps, and the rotary knob from your keyboard.
3. Turn the board over so the embossed GLORIOUS logo is facing up.
4. Using a manual Phillips #00 screwdriver, gently loosen the 8 exterior case screws by a few rotations in the following order:
• Top left
• Top right
• Bottom right
• Bottom left
• Remaining 4 screws in no specific order
A GMMK PRO with a FlexKit installed will only have 4 bottom screws.
5. Once adequately loosened, fully remove each screw in the same order as step 4.
6. Carefully turn the board back over and lift away the top frame.
Replacing the USB-C PCB
1. Carefully lift the PCB & switchplate (the chassis) from the front of the keyboard, ensuring that the wire connecting the USB-C PCB to the PCB at the back of the keyboard is not damaged.
2. Hold the chassis in place, close to the rest of the keyboard, and unplug the USB-C PCB from the main PCB.
3. Unscrew the single screw securing the daughterboard into the bottom case and remove.
• Some GMMK PROs have a small piece of foam covering the daughter board and screw.
4. Align and insert the replacement USB-C PCB, ensuring it sits correctly in the bottom case.
Reassembling the GMMK PRO
1. Return the foam back to the bottom case, ensuring it is aligned and sits properly.
2. Gently plug the internal daughter cable into the USB-C PCB.
• If replacing the internal daughter cable, plug the other end into the main PCB as well.
Note: Make sure the cable is properly routed through its canal in the bottom casing, and ensure that both ends are connected before closing up your GMMK PRO.
3. Replace the GMMK PRO top frame.
4. Re-install the top frame screws, being sure not to overtighten to avoid stripping.
5. Replace your switches, keycaps, and rotary knob.
6. Plug in your GMMK PRO and ensure it’s functioning properly.
