ubiquiti Rocket R5ac lite firmware

I have been trying to flash the firmware to a R5 ac lite. I was using the tftpD64 with the downloaded firmware for the Rocket R5ac   lite. It sat that it loaded but when I go to the browser in dhcp I cant get the aredn page to load. I went in to the default ubuquiti page to see the firmware that was on the router to begin with and it was 7.03 do I have to get it to another version before changing to aredn?
