From a site which has signed factory roms of YU phones taken from its official site.The official site doesn't have them now.They mirrored the official site roms.

there's only one way to find out the outcome by testing it yourself, that is if you are willing to risk a brick
better you use the other alternatives ie fastboot or twrp install image
