X88 pro x5m with S905X5M how to load LibreElec/CoreElec?

Got it off Aliexpress pretty cheap, I thought given that Amlogic and other S905X versions were supported, that I could get it to work? Turns out I was trying to buy the S905X5 but they keep adding letters to it. Anyway just some advice on how to run a kodi-based OS, I would also preferably flash it onto my device rather than run it off an SD card?

Thanks (:
