本文介绍了一个用于更新Android设备的启动分区(boot.img)和恢复分区(recovery.img)的shell脚本。该脚本通过参数指定要更新的分区文件，并使用busybox dd命令将指定的映像文件写入到相应的设备节点上。

#!/system/bin/sh

recovery_DIR="recovery.img"
boot_DIR="boot.img"

if [ "$1" == "$boot_DIR" ];then
echo "update boot img start"
        chmod 777 boot.img
if [ ! -x "$boot_DIR" ]; then
  echo " no boot img file "
  echo " update boot img err , shll exit."
  exit 0
   fi

busybox dd if=boot.img of=/dev/block/mmcblk0p1; sync
       sync
echo "update boot img ok "
        exit 0
fi

if [ "$1" == "$recovery_DIR" ];then

echo "update recover img start"
         chmod 777 recovery.img
if [ ! -x "$recovery_DIR" ]; then
  echo " no recovery.img file "
  echo " update recovery img err,shll exit."
  exit 0
fi

busybox dd if=recovery.img of=/dev/block/mmcblk0p2; sync
echo "update recovery img ok "
exit 0
fi

echo "请输入 ./update-img-ok.sh < recovery.img | boot.img >"
exit 0
