Just purchased the WD MyCloud Ex2. In every review, they have that cool and awesome dark skin, which is one of the reasons why I bought this NAS. And when I open my interface, it’s all white and eye tearing.
Please advise on how to switch the skin from white, to black,
I’m afraid to tell you it has probably been shipped with v1.xx.xxx firmware, which has the nice (at least I prefered it) dark web interface, but has auto upgraded to v.2.10.310 firmware (the current release). The horrible (in my view) white interface came with v2.xx.xxx firmware (also known as OS3) and there is nothing you can do about it.
Some “fixes” were introduced with v2.xx.xxx, but also a fair number of new bugs. For instance the LED behaviour in sleep (powersave) has been changed from all LEDs off in sleep to the utterly incomprehensible all LEDs ON!!!
You could try donwloading the last version prior to v2.xx.xxx which is v1.05.36 from the link below and doing a manual update. You might need to do some digging on here if it refuses to downgrade to find out how to force:
