Bootloader
Enter the bootloader in 3 ways:
- Bootmagic reset: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
- Physical reset button: Briefly press the button on the back of the PCB - some may have pads you must short instead
- Keycode in layout: Press the key mapped to
RESETif it is available
