Install over USB

Works in Chrome and Edge on a desktop. Already running the stock firmware on Wi-Fi? You can install over Wi-Fi instead and keep the stock GIFs.

  1. Plug in the KNOMIHold its button while you plug in a USB-C data cable. The screen shares the USB pins, so the KNOMI only talks USB in flashing mode.
  2. Click InstallPick the KNOMI's serial port when the browser asks.
  3. Set it upJoin the KNOMI-xxxx network shown on its screen and open 192.168.4.1.

This replaces everything on the KNOMI, including the stock GIFs. You can go back to the stock firmware at any time.
