Next/Updates/en
In the web interface click "Nach Updates suchen" (check for updates) under "Update"; if a newer version exists "Neue Version verfügbar" (new version available) appears, and one click on "Jetzt installieren" (install now) downloads the firmware (about half a minute, a bar runs on the display) and restarts. Optionally Next checks by itself two minutes after the start and every six hours (checkbox "Automatisch alle 6 Stunden nach Updates suchen"); the default is off, and installing only ever happens on a button press. Do not unplug the device. Alternatively upload firmware.bin from the releases under "Firmware-Datei". A new firmware only counts as valid after a healthy start (rollback). The very first flash of a CYD with foreign software goes through the web installer, which erases the flash first.
