Firmware

Update over Wi-Fi.

Your patterns, your Wi-Fi networks and your storage are untouched — an update rewrites the program only.

Latest release…

Your device’s address

Android cannot resolve .local — use the IP from the device’s NETWORK screen (hold K2).

Opens your device’s own update page with this build linked. Press Fetch & flash there — your browser downloads the image and hands it to the board. Keep the device powered; it reboots itself when it lands.

If that does not work

Nothing opens? The device and this computer have to be on the same Wi-Fi. Check the address above against the device’s NETWORK screen.
No /update page on the device? It predates wireless updating. Flash it once over USB and every update after that is wireless.
Prefer a file? … and drop it on patternflow.local/update yourself.
USB: the browser flasher writes a complete board from scratch — the same path as a first install.
