Please Note, all Kiwi 3 units purchased after September 2016 will have the most recent Firmware version already. The updater app is only available for iOS. 


To update the firmware, use an iOS device and simply download an app called “Kiwi3 OTA”. Once you open it you will see your Kiwi listed, select it. You will see your current firmware listed at the top and the available update below. Click update, give it a few minutes to download and update. Do not exit out the app or let the phone display close or lock. It will then reboot and then you will be finished.
