I read a lot this days, and seems that Android version of Mx4 have the preloader locked. Unlock Bootloader and use SP flash tool is not enough, because we can't acces to the partitions. But the information is from last year, people saying they are so close to do it. But in this year I don't see information yet.
PS: Meizufans.eu doesn't work fine to me, I don't know why, but I see so few topics in the forum, and when I search in a Browser, the links of forum send me to another link.
