Clean OS (Debian), OpenMediaVault and other "firmwares"


I have another stupid question.
In case of any issue is there a way to restore the original firmware ?


I did a fresh install of clean Debian with update to Stretch on a new MyCloud Gen 2

I changed the hostname according to

That was a bad idea; when i try to log in with ssh i get a “Permission denied, please try again.” when i put in my password.

I searched here but found a dead link, and no idea how to fix it. preferably without opening the case to extract the harddrive.

can anyone help me?

also what would be the right way of changinge the hostname from “wdmc” without loosing ssh ???

Thx in advance for your help :slight_smile:

Forget what i wrote !!!
with the update the ssh config has changed, new rules do not allow for login with user root.
you can log in with another user (if you have one), and then switch to root with: “su root”
or you can edit that configfile to allow root access for root


unbricking with USB as described in
does not work.
tried two different usb 2.0 sticks, i only get a yellow light instead of the blue one when i swticht my cloud gen 2 on, but it seems to boot the system from harddrive. No telnet, still ssh with permission denied.

The USB-stick only works if the OS on HD is not bootable


startet fresh and changed hostname on debian 8 jessie with this manual:

change your hostname in:
nano /etc/hostname

added the line “ whitey” in:
nano /etc/hosts

run this command:
/etc/init.d/ start

change hostname with
hostname newname

check new hostname with:

reboot and see if it works


You are sure its a gen2


Yes, it is a gen2


Noob here - just to be clear, by changing firmware on Gen1 or Gen2 mycloud, I lose ability to remote access it via, right? I am tempted to change the firmware to clean Debian since I need autossh and screen (on gen2 at least) but am willing to know all the “catches” before I proceed :slight_smile:


@cloudmaniac, yes. Using alternative firmware you loose all WD functional, but get access to almost all Linux software (OwnCloud, SyncThing, GSync, OneDriveSync and many other “Cloud” stuff).
But need install and configure all of it manually…


@Fox_exe Yes, was thinking its like that. I am ok with “pure” linux. Currently wd cloud access is cool since not all drives I have are behind public accessible IP - WD does all the relaying :wink: If I switch firmware, relaying is up to me :sweat_smile:


Hello all.
I just get an old WD MyCloud Ex2 for free. I have the newest Firmware.
I wanted to install Debian and OMV but i get the Purple LEDs.

I downloaded the file for My Cloud Mirror Gen1 and Install the “debian-jessie-firmware-test” via the webgui. (via Manual Firmware upload?!?). After Reboot i get the Purple LEDs.

Du i have to push the reset button while reboot? Or do i have to push it anyway?

Thanks for help and Sorry for my english.


@Fox_exe Could you please make the new kernel for the EX2 Ultra with BTRFS Support? I don’t find any kernel that support is…not the 4.14, 4.15, neither the 3.10. That would be really fantastic!


@Fox_exe Hey there!
I have a problem with step 2 (After reboot - device get new IP address, find it and connect via Telnet) on My Cloud EX2 Ultra.

After flashing bin file I have waited few minutes but couldn’t get an IP, so I have turned it off and on.
Right now my device is blinking Blue led, HDD leds are off and fan is working very loudly.
Maybe it’s a problem with subnet? My network is on

Any clues how can I get this to work? as I’m stuck a bit right now, and not really sure what should I do/check.
