OK, now is 100% clear. I made SD cart with win disk imager, but no luck... It just shows M8S+ logo then go back to black screen then back to logo, to screen and so on... I've been holding reset all that time. So I even cannot go to libreelec screen. I will try with 20160906 now.
EDIT: WHen I replace script s805_autoscript with old one from your download then it freezes on M8S+ logo after releasing reset button.
EDIT 2: No luck with 20160906 also. It freezes at the very beginning on M8S+ logo.
