Log on to the master controller app via webbrowser and go to the admin section which I think ha s the firmware update section.
Note upload the firmware to the slave first and then to the master. Note, this will reset everything to factory settings..
Make sure you have the unleashed app installed on your iPhone or iOS device so you can configure it.
note: Saved Settings from 200.7.10 will not work for 200.6.10
