WD MyCloud 4TB. I upgraded the firmware to v04.00.00-607 after installing (I didn’t know any better at that point). No, I wasn’t happy with the results, and WD tech support was a waste of time.
I downgraded the firmware as described, w/o any problems. However, after rebooting with the downgraded firmware (v03.04.01-219), Twonky wouldn’t start, and the unit generated the “Media server database internal server error. (400162)” message. (Rescanning or rebuilding didn’t work, because Twonky wouldn’t start.)
I re-applied v04.00.00-607, and after rebooting everything (including Twonky) was back to normal.
I’m told that MyCloud was supplied with Twonky v7.2.6; but I have v7.2.8. So my surmise is that, in my case, the v04.00.00-607 update didn’t just update the firmware; it also updated Twonky to v7.2.8. Downgrading to v03.04.01-219 didn’t change that, and there is some incompatibility between Twonky v7.2.8 and FW v03.04.01-219 which prevents Twonky from starting.
Something to consider before downgrading to v03.04.01-219.
Registered only to say thanks for this post PVS0705, you’ve saved a 40inch samsung TV come huge laptop monitor from having a WD mycloud 4TB paperweight embedded in it… if you catch my drift…
Updating firmware to V 4 caused all sorts of nightmares…
Transfer speed dropped through the floor… before upgrade was avg. 60MB/s write 80MB/s read to/from laptop. dropped to 20/25 respectively.
Kept losing contact with USB external drives through hub (couldn’t navigate to the shares using samba even though web interface showed everything ok) worsened to not being able to access ANY shares !!! (yes i have lots of storage attached, 7 shares and counting)
Web interface was becoming unresponsive resulting in having to do a power cycle (I know, not good and scary each time wondering if it would come back).
Most importantly, me forgetting I had updated the firmware last week and was looking at all sorts of possibilities/poblems with my network/laptop/hard drives etc…
Thank you GOOGLE, you save the day again
Thank you PVS0705 again for doing the hard bit and finding out how to downgrade then post the info here… your a star…
As mentioned earlier in this thread, wonder what WD broke with this update? is it possible they busted some samba stuff? What software is evryone running that finds the update unstable? Windows?
But, at least WD helped us revert back to previous firmware and all is running smoothly again…
Thank you WD for an excellent product… even the best of us mess up sometimes!!!
If I downgrade to v03.04.01-219 will it also eliminate the 64-bit page size that showed in the v04 firmware? I’d like to use Crashplan again but cannot because I’m not tech savy enough to build packages for the 64-bit page size.

Simple answer is yes. This is one of the main reason why people stay at version 3.4.
Add me to the list of satisfied “Downgraders”. Mine was doing OK with the new FW, but I was having some remote access issues and could not email links to pictures from the WD Photos app. Several days ago I tried the long restore process… no improvement
Today I did the downgrade and, while file transfer speed isn’t noticeably faster (maybe a little bit), my remote issues have cleared up. I can send email links to photos and the response of the mobile apps to the MC is noticeable better.
Another big thank you to the OP. I was finally successful at downgrading to the v3 version after a couple of failed, bungled or otherwise disastrous attempts…
After disabling the scanning services and all the media features, I now have a fast NAS for backup.
Excellent post, many thanks. Post the V4 firmware upgrade my 2TB Cloud ran like an absolute dog, running very slow was the least of my problems. Downgrading to the previous version as described in your post has got my Cloud working again, fast etc. I’ve now disabled auto update and won’t be upgrading in a hurry,
i read your post, and is there a way for me to downgrade and set it from mac os ? i am using mac os, and the winscp is windows app.
I am finding my mycloud using firm v4, so sluggish, the speed for transfer , read and write only max 12MBps, and i have no idea what is wrong, i thought the unit is faulty, and but when i read your post, that it make sense might be the firmware screwup, and i was on email with th wd tech support for last few days, and they never said might be firmware problem, just ask me to reset, and try again, and factory reset and **bleep** what if my data lost ? they ask me to back up, yeahh my problem is not i want to back up or transfering my data to another NAS, and so **bleep** slowww, everytime i click copy, they message is preparing… not copying…
