WD has apparently released Firmware 04.06.00-111 (4/15/2022) for the first generation single bay My Cloud (P/N: WDBCTLxxxxxxx- 00).

Release Notes:

Firmware Version 04.06.00-111 (04/15/2022)
As of April 15, 2022, support for prior generations of My Cloud OS has ended. We’ve made the following changes as part of this release:

  • Disabled Cloud Access support
  • Disabled Notification Email support
  • Added My Cloud OS 3 End of Support message in the My Cloud dashboard

You will continue to have local access to your stored content. Remote access, security updates, and technical support will no longer be provided. Check out our recent My Cloud updates to learn more.

Note: Remote Access using the My Cloud OS3 mobile app and the web portal have both been removed. Local network access using the My Cloud OS3 mobile app (for Android) also appears to no longer work.

Nice writeup!!

I will say one thing: Given the nature of WD support (i.e. it’s over for OS/3); I would not touch this update with a 10’ pole.

One can always roll back or unbrick back to earlier firmware if they don’t like 4.06.00-111. :wink:

Edit to add: What ever one does they should give serious thought and consideration to blocking broadband access to their OS3 My Cloud at the local network edge (at their network firewall/router).


Thanks for the suggestion.
