好多包都是这样子,从什么时候开始要在棉花糖基础上刷,旧的固件出现这样的。starting from 20160615 nightly build we require MM firmware. If you're running LP firmware it should fail saying that "asus.verify_trustzone" assert has failed. In order to update your firmware to MM one you can either flash ASUS MM rom in stock recovery or flash a package that will update your FW which you can download right here
