Clover update for Sierra install

[Private]

Hi guys. I have working old version of clover and 10.10.5
Decided to update to Sierra, created USB not to mess with woking boot loader. And instantly I have a problem. Clover (3899) boots till drive selection screen and that is all. after selection - black screen. Does not matter what I've choose or is it clean setup or modified with working config and dsdt and kexts. Searching net didn't help. Maybe anyone have some ideas what can that be? would be grateful
