分区说明
boot:存放内核和ramdisk的分区.
radio:这个是radio所在的分区，(基带):
recovery:Recovery分区.恢复模式
system:系统分区.
userdata:数据分区.
cache:缓存分区
hboot:这个是SPL所在的分区.很重要哦.也是fastboot所在的分区.刷错就真的变砖了.
splash1:这个就是开机第一屏幕了.
oem分区(运营商配置文件，和运营商配置有关):
vendor
6，刷写motoboot镜像：(这个是bootloader的组合镜像包，简称BL，最好不要乱刷!
这个只能升级不能降级这个必须与gpt版本一致才能刷进去，。并且刷这个容易变砖!)
