WDMycloud救砖 #

所需文件下载地址：

My_Cloud_GLCR_2.31.204.bin: http://ct.imagemagick.top/f/18418398-858576108-9af5da
usbrecovery.tar.gz: http://ct.imagemagick.top/f/18418398-858574884-213c7e

然后将一张U盘格式化为 FAT 32 格式，将下载好的 usbrecovery.tar.gz 解压缩到U盘根目录，确认盘根存在解压缩后的 boot 目录，目录内包含四个文件。

接着将磁盘插到设备唯一的USB接口上，给系统上电，启动设备即可。重启后进入恢复模式，通过telnet来链接设备进行操作。

/dev/sda为wdmycloud内置硬盘，/dev/sdb1为插入的U盘。

初始化磁盘分区

mkfs.ext4 /dev/sda

建立新分区所有提示都输入yes或y

parted /dev/sda
mklabel gpt
mkpart primary 1049kB 2149MB
mkpart primary 8591MB -1MB
mkpart primary 7517MB 8591MB
mkpart primary 2149MB 3222MB
mkpart primary 3222MB 4296MB
mkpart primary 4296MB 6443MB
mkpart primary 6443MB 7517MB
q

格式化分区

mkswap /dev/sda1
mkfs.ext4 /dev/sda2
mkfs.ext4 /dev/sda3

安装恢复镜像

mkdir -p /mnt/usb /mnt/root
mount /dev/sda3 /mnt/root
mount /dev/sdb1 /mnt/usb
cp -r /mnt/usb/boot /mnt/root/
cd /mnt/root/boot
rm uImage uRamdisk
mv uImage-wdrecovery uImage
mv uRamdisk-wdrecovery uRamdisk
cd /
umount /mnt/root /mnt/usb
sync

以上操作完成后，查看分区信息如下：

/ # fdisk -l

将 U盘拔下来，终端执行最后一个命令reboot -f重启，接着耐心等待设备重启完毕。

重启完成后，通过浏览器浏览ip进入Web 界面刷入固件。如下页面，点击选择文件，选择下载的My_Cloud_GLCR_2.31.204.bin文件，等待恢复完成重启。

重启完成后，通过ip进入mycloud，进行初始化设置即可。
