Help For Dead Mimax 3/64 652 (pro?)

Hi guys, I've just bought a Xiaomi Mimax and, since I'm italian, I've tried to install the international version of the xiaomi rom.

I've installed twrp with no errors.

After that I've tried to install the rom, I've choose this: MIMAX 6.7.28 v8. Probably my choice was wrong. The correct choice should be Mimax pro....

I've used adb sideload to install the rom (I don't know if this could be a problem) but, I've got no error.

I've rebooted the phone but, now it's totally black, no life...
