I've recently installed a fresh version of LibreELEC (coming over from OpenELEC) and when I try to boot the Pi 2, it displays a solid Red and Yellow LED. If I kill the power, remove and reinsert the Micro SD card and try to boot everything works fine. As soon as I turn it off and try to reboot it, the same error occurs.
The MicroSD with OpenELEC still boots fine every time, it's just the Micro SD with LibreELEC on.
