Android刷机脚本updater-script实例讲解
在这里引用的是c8812的深度os刷机脚本

#这个是对于build.prop机型名称进行校验，校验设备是否为c8812或者c8812的一些别名，校验成功的话继续刷机操作，失败的话终止刷机，只要是起到一个保护的作用，一面刷错机器 mount(“ext4″, “EMMC”, “/dev/block/mmcblk0p12″, “/system”); #这个是挂载system分区，方便后面进行读写，用到的参数在命令讲解中都有说，这里需要注意的就是分区不能写错了，挂载出错的话就会导致刷写到错误的分区上，如果是无关紧要的分区可能只是溢出，要是把引导分区刷了，就变砖了 package_extract_file(“system/bin/backuptool.sh”, “/tmp/backuptool.sh”);
