How can I go back to my previous firmware version?

My WdMyCloud device has become very slow and the dashboard takes for ever to show up. All user interactions take for ever. All this happened after I updated the firmware to the new version 4.00… yesterday. Can anybody help me in going back to the previous firmware version? Everything was working flawlessly in that version.

Thanks.

something we’d all like to know

you’d think it would be straightforward wouldnt you

The inertia from WD is deafening.

Can we have a fix today please?
