This is a fairly simple task but requires that you be a registered user at www.hautespot.net in order to download the latest firmware to your computer. Once you are a registered user, you can access Hautespot’s download page. Once there, click your devices category then click software to get to the firmware version you would like to update to or back rev to. Download the file to your desktop or your preferred directory, then open up your web browser type in your devices IP Address and log in to your HR-WINDi . Now click Firmware, from there and under Firmware settings click the browse button and direct yourself to the directory your downloaded firmware update is saved too. Click ok  then depending on what firmware update your doing place a check mark in the box to the right of “Reset Factory Settings,”  if you are doing the 1911 update DO NOT check this box! Now click update and DO NOT interrupt the device while it is doing the update. Once it is done the device will reboot and will then be ready for you to use.
