Install with Fox_exe's script
Eng:
1. Download Autoinstall.zip
2. Download dump of any firmware (Backup, OMV, CleanDebian)
3. Unpack and copy all to one folder in NAS (For example - to "Public" share)
4. Go to web-gui, enable SSH. Connect to WD via SSH (Use PuTTY for this)
5. Run:
cd /DataVolume/shares/Public
chmod +x install.sh
./install.sh
6. After ~10min device reboots. All done. Try you new firmware!
* Optional: Run "/run_me_after_reboot.sh" for few tweaks and cleanup.

=======================================================================================
Howto replace or restore original firmware:
* You can use any of *nix system. I use Debian (Ubuntu similar).
* All command runing from root user. Or use Sudo.
* First thing after boot in liveCD - install software: apt-get update && apt-get install mdadm parted
!! For install new HDD - go from p.1. If you repare exist HDD - go to p.8-2
1. Use fdisk -l (or parted -l) for see what name have you WD's HDD.
* For me - its /dev/sdb. Replace it to your hdd name!
2. Run parted utility:
parted /dev/sdb
3. Type "print" for see what partitions exist on disk
4. Remove all: Type "remove 1" (where 1 - number of partition)
5. Crete new table:
mklabel gpt
mkpart primary 528M 2576M
mkpart primary 2576M 4624M
mkpart primary 16M 528M
mkpart primary 4828M -1M
mkpart primary 4624M 4724M
mkpart primary 4724M 4824M
mkpart primary 4824M 4826M
mkpart primary 4826M 4828M
set 1 raid on
set 2 raid on
6. Ok, type "quit"
7. Format data partition:
mkfs -t ext4 /dev/sdb4
7-1. Format the swap partition:
mkswap /dev/sda3
8-1. Prepare main RAID partition (For rootfs): mdadm --create /dev/md0 --level=1 --metadata=0.9 --raid-devices=2 /dev/sdb1 /dev/sdb2
* Type "watch cat /proc/mdstat" and wait 100%. Then - [ctrl] + [c] for close.
8-2. Stop auto-loaded raid: mdadm --stop /dev/md127 (Sometimes you can see another numbers - see in: ls /dev | grep md)
8-3. Start normal raid (/dev/md0 is important!): mdadm -A /dev/md0 /dev/sdb1 /dev/sdb2
9. Use data partition as download folder:
mount -t ext4 /dev/sdb4 /mnt
cd /mnt
10. Download one of arhive's to /mnt folder:
v3.04.01-230: https://drive.google.com/file/d/0B_6OlQ_H0PxVQ2l5MTNvQk1xSUU
v4.01.02-417: https://drive.google.com/file/d/0B_6OlQ_H0PxVcENERjVxVHFzZzg
11. Extract by console:
tar xvfz original_v3.04.01-230.tar.gz
12. Ok. Upload backup images to WD's hdd:
dd if=kernel.img of=/dev/sdb5
dd if=kernel.img of=/dev/sdb6
dd if=config.img of=/dev/sdb7
dd if=config.img of=/dev/sdb8
dd if=rootfs.img of=/dev/md0
13. Shutdown PC. (Or use "Logout" in menu)
shutdown -p -H 0
14. Connect HDD to WD's plate and turn on WDMyCloud. Wait ~5-10 min.
There are guides on how to build the software from source code:
It's better to re-create the kernel from the source code. So here comes the method in Unbricking without opening

Note: The bottle neck is CPU. AVG speed is 10MB/s via Arcfour or 8MB/s with default cipher algorithm
Ref: man sshd
protocol 2, forward security is provided through a Diffie-Hellman key agreement. This key agreement results in a shared session key. The rest of the session is encrypted using a symmetric cipher, currently 128-bit AES, Blowfish, 3DES, CAST128, Arcfour, 192-bit AES, or 256-bit AES. The client selects the encryption algorithm to use from those offered by the server. Additionally, session integrity is provided through a cryptographic message authentication code (hmac-md5, hmac-sha1, umac-64, hmac-ripemd160, hmac-sha2-256 or hmac-sha2-512).
