在安卓手机中Fastboot是一种比recovery更底层的刷机模式（俗称引导模式）。就是使用USB数据线连接手机的一种刷机模式。相对于Recovery、Fota等卡刷来说，线刷更可靠，安全。

recovery是一种卡刷，就是将刷机包放在sd卡上，然后在recovery中刷机的模式
fastboot是一种线刷，就是使用USB数据线连接手机的一种刷机模式

使用 Fastboot 刷机必须先解锁BootLoader，否则无法刷机
解锁BootLoader的方法是在开发者模式中开起OEM unlocking开关。
如开发者模式隐藏，请进入Settings--System--About Phone--多次点击build number 即可打开隐藏的开发者模式。

Setting 》 System 》 Advanced（Developer options）》OEM unlocking

目前主流Android手机进入Fastboot的方式为【关机】 【音量-】+【电源键】

ADB 命令为:    adb reboot bootloader

system:系统分区.
userdata:数据分区.
cache:缓存分区
recovery:Recovery分区.
boot:存放内核和ramdisk的分区.
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Log屏幕.
radio:这个是radio所在的分区
