User Fox_exe has posted unbricking directions for several My Cloud including gen 2 My Clouds. Here is the link for the gen 2:

# Use Debian/ubuntu or any other linux distro (USB/CD Live image)
# All "/dev/sda" change to your disk! (List disks in system: "parted -l")
# If this is new disk or damaged (formatted) old, recreate partitions first:
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

mkswap /dev/sda1
mkfs.ext4 /dev/sda3
# Download and unpack files from WDMyCloud/WDMyCloud-Gen2/Developing: uImage-wdrecovery and uRamdisk-wdrecovery
# Write it disk:
mkdir /mnt/boot
mount /dev/sda3 /mnt/boot
mkdir /mnt/boot/boot
cp uImage-wdrecovery /mnt/boot/boot/uImage
cp uRamdisk-wdrecovery /mnt/boot/boot/uRamdisk
# Done. Connect disk back to WDMC and turn on.
# After few minutes WDMC boots to "WD Recovery". Go to webgui and upload official firmware.
# Done!
As always its a good idea to do a 40 second reset or do a System Only Factory Restore through the Dashboard after unbricking either a gen 1 or a gen 2 My Cloud.
