Bennor · January 28, 2016, 2:33pm

UPDATE (4/15/2022): WD has terminating OS3 support as of April 15th of 2022!!! Generally one’s OS3 My Cloud will remain operational and accessible on the local network. WD supported remote access service (MyCloud.com / OS3 mobile apps) has been be terminated. The second generation single bay My Cloud ((P/N: WDBCTLxxxxxxx-10, FW 02.xx.xx)) unit is not affected by the OS3 support termination, the second generation single bay My Cloud can be updated to OS5.

UPDATE: It appears WD is now blocking users from being able to download past versions of the v3.x, v4.x and v2.x firmware.

A listing of firmware versions for the single bay/single drive My Cloud and their WD download link if available. Note that both the v4.x and v2.x firmware are listed below. Make sure to use the correct one for your single bay/single drive My Cloud model. You cannot (at this time) load the v2.x firmware to v4.x My Cloud devices. Directions for downgrading firmware is located below.

Note: Downgrading the firmware will break certain features like remote access using the MyCloud.com site.

Note: These directions and files are for OS3 single bay My Cloud units ONLY!!! If using OS5 firmware on a second gen single bay My Cloud see the OS5 subforum (https://community.wd.com/c/os5/my-cloud-os5/257) for any issues with that firmware!!!

How to downgrade to earlier firmware (v4.x)

https://community.wd.com/t/easy-method-to-downgrade-to-previous-version-of-the-firmware/93489

How to upgrade from firmware file using SSH (v4.x)

Connect to My Cloud using SSH.
Change to the Public folder: cd /DataVolume/shares/Public/
Download the firmware file: wget http://download.wdc.com/nas/<name of firmware file>
Extract the firmware file: unzip <name of firmware file>
Issue the firmware upgrade from file command:
/usr/local/sbin/updateFirmwareFromFile.sh /DataVolume/shares/Public/<name of extracted firmware file>

After My Cloud reboots post firmware upgrade one can remove the firmware upgrade files from the Public folder using Windows File Explorer or Macintosh Finder. Or one can issue the following commands from the Public folder using SSH:

rm -f <name of firmware file>
rm -f <name of extracted firmware file>

How to downgrade to earlier firmware (v2.x)

It has been reported that if one follows the steps below they can downgrade the firmware on a 2nd gen v2.x firmware single bay/single drive My Cloud. Proceed at your own risk!!!

Download the v2.x firmware version that you want to downgrade from the links above.
Open web browser, navigate to My Cloud Dashboard (http://wdmycloud/ or http://wdmycloud.local). If needed, log into the My Cloud Dashboard.
On the Dashboard, select Settings > Firmware Update.
Set “Enable Auto Update” to “OFF”. This will prevent the My Cloud from automatically updating to a newer firmware version post downgrade to earlier firmware.
Under “Manual Update,” click the “Update from File” button/link.
Browse to the directory where where previous single bay/single drive v2.x firmware was downloaded. Select the firmware image file (.bin), then select the “Open” button/link.
Follow the additional onscreen dialog messages (if any) when prompted to install the firmware file.
When the firmware has been installed the My Cloud should reboot with the older firmware version installed and listed on the My Cloud Dashboard.

Note: If there are any problems post firmware downgrade, perform a 40 second reset using the reset button on the back of the My Cloud. Sometimes this can clear up certain issues that occur post firmware install.

Is that possible to install the latest v4 firmware on a v2 one? As I read the v4 hardware is “weaker” and older than the v2… how come? I mean the version number shows me opposite. Unfortunately all the third party apps are available for the v4 firmware… that’s why I’m thinking of changing the firmware. Pro and contra?

Bennor · July 14, 2016, 4:40pm

No.

cpt_paranoia · July 14, 2016, 5:11pm

Because the marketing/product development loons at WD decided that they didn’t need to announce they had launched a completely new product onto the market, with new hardware, and a totally new operating system, and didn’t need to change the name, and they thought it wouldn’t confuse anyone to call their new firmware ‘v2’, even though it’s supposedly newer than the previous v3 and v4 firmware.

You know it’s a crazy thing to do.
I know it’s a crazy thing to do.
The only people who don’t think it’s a crazy thing to do are the fools in WD’s product development department…

Does this process work on a Gen1 or Gen2 MyCloud?

Bennor · April 28, 2017, 10:01am

That might work for 2nd gen v2.x firmware single bay My Clouds. Fox_exe previously posted a method to unbrick a 2nd gen single bay My Cloud using USB: https://drive.google.com/file/d/0B_6OlQ_H0PxVQVhnLVJOdDZISUU/view
