I purchased a HotDox V2, which has been great:

  • The keyboard has LEDs! if that’s your thing.
  • Left and right sides can be used independently.
  • LCD screen show you the layer you’re in.

But I accidentally flashed it with the HotDox V1 firmware, and needed to flash it back.

The steps are pretty simple:

  1. Get the HotDox V2 firmware. I had to e-mail kono directly at support@kono.store.
  2. press the reset button on the side you’re flashing(different sides different firmwares)
  3. Erase the firmware with dfu-programmer: 
     dfu-programmer atmega32u4 erase
  4. Flash the firmware (example has the right side) 
     dfu-programmer atmega32u4 flash hotdox76v2_rightkb_via.hex

And that’s it!
