I have created a bootable SD with the tool for a Raspberry Pi 3 but it does not boot.
When powering the RPi it displays the initial color gradient splash screen and nothing happens afterwards.
I have tried creating on Linux (Kubuntu 16.04) and Mac OS X (El Capitan).
Then I tried creating the SD with the Startup Disk Creator and the downloaded 126.96.36.199 image and same result.
Just to be sure that the SD itself is bootable I downloaded the Raspbian Lite image and again using Startup Disk Creator I got a bootable SD.
My conclusion is that the problem must come from the LE image but I am not sure.
