Bricked 4TB MyCloud

Hello,

i have a Problem, i tried to Flash my 4tb My Cloud with the tut from Fox_exe for OpenMediaVault and bricked My Cloud, i see the White LED glows. I put out the WD Red Harddrive from the case and hung she on a sata to usb Case and Read out the Shares Folder´s and Transfer to 2 other Harddrives to saved the Data on the WD Red Hard Drive.

and my Linux understand is bad :cry:

I Follow the steps from the Method one Recover Tut from Fox_exe, i remove all Partions with a Lubunto Live CD in the root mode (Sudo su) …Step 1 to Step 7 works and Step 8.1 i type the line in the command and see a message that mdadm is not installed…

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

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.

is there an easy way for dummies to solved the problem with a image or something, i found a 4tb image for the mycloud ( Image for 2tb 3tb and 4tb)
