A free replacement firmware exists.

Get started

One known way to put open firmware or software on this device, easiest first. Each one links to the project's own instructions.

Before you start
  • Back up your data and settings (and the stock firmware, when the guide says how).
  • Check the exact model, hardware revision and firmware version against the guide: a close model may not work.
  • Charge the battery or use a stable power supply; do not unplug during the install.

Put the keyboard in bootloader mode (reset button or key combination, see its README), then flash a QMK build. Many of these keyboards ship with QMK already; a different original firmware may not be restorable.

OpenDeviceDB links to each project's own instructions and tools; nothing is flashed from this site. Flashing is at your own risk and may void the warranty.
