No. You cannot load the first gen v3.x or v4.x firmware to the second gen v2.x My Cloud. Doesn’t work like that. Nor can one load the v2.x firmware to a first gen v3.x/v4.x My Cloud. Each generation has slightly different hardware and use different firmware versions.
Try, if you haven’t done so already, downloading and using the initial firmware 2.10.302 (10/7/2015) for the second gen v2.x single bay My Cloud units. Links to most single bay My Cloud units can be found at this link:
Also as a troubleshooting step, after uploading the My Cloud firmware to the unit, try a 40 second reset.
