Jrman thank you very much to to take your time to reply and excuse me if my questions seems stupid but my Linux knowledge is pretty basic, i use it mainly to repair windows boot problems and data recover.
Linus Torvald has nothing to worry about my Linux skills!
I knew that boot image was in the firm and how to use (g)parted.
I understand that partition sizes for a 3 TB disk are the same as you write for a 2 TB disk in but the ext4 being larger.
How can i use the scripts you said without SSH?
I was able to run the script “updateFirmwareFromFile.sh” in /usr/local/sbin to perform the de-brick.
I downloaded the firmware zip and extracted the .deb file and planted it on the MyCloud in /CacheVolume
Then did… /usr/local/sbin/updateFIrmwareFromFile.sh /CacheVolume/sq-030104-139-20131028.deb
Worked like a charm to undo my “soft brick”. I say soft brick since the UI was non-functional but ssh was fine.
I don’t understand the presence of 8(?) partitions in your partition layout of My Cloud 2TB.
What’s the purpose of partitions 5,6,7 and 8?.
- Must i simply dd the 2 GB rootfs.img to both raid partition, repartition the other partition and reconnect the disk to My Cloud booting it in a normal way?
What make me though about OS partition image is that the guide to recover bricked MBL 3 TB when there is no dashboard or SSH access use it instead of the raw boot image from his firmware.
The unzipped 203 mb file is a 4,31 GB disk image of 4 partition s:
[GUIDE] Debrick MyBookLive v2.0
Guide 2 (3TB MBL)
1) Download the virgin disk image (02.41.05-034) (203MB) from
2) Extract with 7-zip and you should have a file called mybook3tb.img
3) Format an 8GB+ thumbdrive or external usb hard drive to NTFS and copy mybook3tb.img to it
4) Download SystemRescueCd and burn it to a CD
5) Shut down your computer and remove the cable from your computers hard drive so we don't erase it by mistake
6) Hook up your MyBookLive to a SATA port on your motherboard or buy an eSATA to SATA cable or dock and hook up the drive that way. You can try a USB to SATA cable but success rates vary
7) Turn on your computer and tell it to boot from the CD drive
8) When the system rescue cd menu comes up, select to "directly start the graphical environment"
9) Open gparted and check to see where your MyBookLive shows under. In my case it shows up under /dev/sda
The drive should contain several EXT3 partitions and a rather large EXT4 partition
If your drive shows up under sdb, sdc, sdd etc. just substitute the proper name for the drive when getting to
dd if=/mnt/usb/mybook3tb.img of=/dev/sda bs=1M (DON'T ENTER THIS COMMAND YET)
Now in gparted check to see where your thumbdrive shows up. In my case it shows up under /dev/sdb1
If it shows up under sdc1, sdd1, sde1, etc. just substitute the proper name for the drive when getting to
mount -t ntfs /dev/sdb1 /mnt/usb (DONT ENTER THIS COMMAND YET)
10) In terminal type the commands below (Make sure you change sdb1 (For the thumbdrive or usb hard drive) and sda (for the MBL hard drive) to whatever they show up as in GPARTED)
mount -t ntfs /dev/sdb1 /mnt/usb
dd if=/mnt/usb/mybook3tb.img of=/dev/sda bs=1M
11) Look for any errors in the terminal window (output should look similar to below)
4420+0 records in
4420+0 records out
12) Logout of the SystemRescue CD and shut down the computer
13) Hook up the pcb to the MyBookLive hard drive and screw it down with 2 screws for now and then hook up the ethernet and power cord and try booting the drive again without putting it back in the case
14) Now from the dashboard do a Quick Factory restore to format the data partition
15) When the quick factory restore is complete power down the MyBookLive
16) Put the drive back together as you are done!
I disassembled it today and received a 3 TB drive to try to backup my data.
Tomorrow i will have time to attach the drive to sata and look what the drive has inside.
