Installation farmware got stuck, farmbot unaccessible

Our farmbot at school got stuck in an update and is since then no longer accessible. When the installation of the farmware started the webapp no longer connects to farmbot so even a reset is not possible. What can I do?

If the bot won’t connect to the WebApp and also does not open up its configuration WiFi, you should try to flash the SD-card and set it up with the configurator again.

Sometimes it comes up again if you reset the bot by unplugging, waiting a minute and plugging it back in. But as this does not work every time, flashing the SD-card is needed sometimes to get it running again.
