this is not my own work. I am just mirroring Ivan's ROM published into other chinese forum channels. this is bleeding edge android lollipop 5.1 for Xiaomi Mi2(s) codename aries. don't use this build on other phones. all credit goes to Ivan for this incredible work. buglist: - screen stucks blank for a while at first start [after flashing ROM], but no issue at all on further reboots/boot ups - bluetooth stack is rather fragile - you tell me!
