This guide will show you how to perform the downgrade without the aid of a file browser such as WinSCP
- Enable SSH
- login to your WDMyCloud dashboard ( http://wdmycloud/ ) → go to Settings → Network → and change the slider for SSH to ON
- Download Putty, an SSH client
- Open Putty and connect to WDMyCloud via SSH
- Enter the address to your WDMyCloud in the Host Name ( or IP Address ) field.
you can either enter the hostname which is wdmycloud or the IP Address which you can find by looking on
the dashboard; go to Settings->Network-> and it will be listed next to IP Address
-
Click Open on the bottom to initiate the connection
-
If this is your first time using SSH for your device you will need to accept the Host Key by clicking Yes
NOTE: with putty, copy and pasting commands is quite simple, you will select the commands from this screen,
go back to the putty screen, and to paste you will just RT-CLICK your mouse anywhere on the screen.
CTRL+V (paste) by default is not supported in putty.
-
enter the following command and press enter
nano /etc/version
depending on which version of firmware you have, the number you see may vary but for most it will probably
say 04.00.01-623
use the right arrow on the keyboard to scroll right to the end, delete the entire line and paste in the following
03.04.01-219
save the file by doing the following: hit CTRL+X then press y then hit enter.
- Import the version 3 firmware, extract and install (downgrade)
-
enter the following commands. each line is it’s own command. one line at a time then press enter.
cd /DataVolume/
wget http://download.wdc.com/nas/sq-030401-230-20140415.deb.zip
unzip sq-030401-230-20140415.deb.zip
rm -f sq-030401-230-20140415.deb.zip
/usr/local/sbin/updateFirmwareFromFile.sh /DataVolume/sq-030401-230-20140415.deb
-
You will then see a lot of verbose output from the update process. Give it some time, mine took about 8 to 10 minutes.
Here is the output of the upgrade (downgrade) process for those interested
Once the LED on your device is a solid blue (not purple) you can access the GUI. You have successfully downgraded your device.
Few side notes:
- If you plan on using putty (which I am sure you do, otherwise you wouldn’t have downgraded) then secure SSH access
to your device by changing the default root password. Restart the session in putty by rt-clicking the top of the program
and clicking “Restart Session” or just open putty and connect with above instructions. Login with the default root
and welc0me. Once logged in issue the following command passwd and hit enter. You will then have the ability
to change the root password to something more secure.
- If you like keeping things tidy and would like to remove the firmware file issue the following command once back into
shell
rm -f /DataVolume/sq-030401-230-20140415.deb
