Easy method to downgrade to previous version of the firmware

Thanks this worked for me!

When performed properly, does this roll-back method result in any loss of data; either on the shares or in the configs (i.e. user accounts, etc), or does it leave everything else there just as it was before?

Hi cagoune. I do not have much technical knowledge. I have listed the steps used by the WD support person.
Did you reboot the device after changing the version? You need to reboot the device before applying the manual firmware upgrade.
Sorry I am not of much help.

Hi iPCMD - as far as i know this roll back won’t result in any data loss or change is settings or shares etc. All my files and settings remained the same.

iPCMD - Just a quick suggestion if you don’t mind. If you are scared of losing your files I would suggest backing up all the files before you go ahead.

Registered just to thank OP.  Latest firmware is rubbish. Downgrading made my device usable again.

Also, FWIW, my tip is to stop using DLNA in favor of Samba.

I tried this today and followed the instructions step by step, but also got the error message “not enough space on this device to update”. Would appreciate any help to complete the downgrade…

Ha! I solved it myself. You need to have the BIOS saved onto the WD Mycloud drive, e.g. on the Public Share folder. I was trying to update the BIOS with the deb file on my laptop. Doh!

My firmware was on the HDD of my PC, so your error was caused by another factor, it would seem.

great, thanks for posting this, it worked but my transfer speed are not super fast i get 6mb writing and 5mb copying from the my cloud, at least now its constant speed…

Thanks this worked also for me!

Yes! Worked for me, too. Firmware was on my PC not on the My Cloud. It is now indexing ALL my media files without getting stuck and is responsive as it was originally.

Of course, this begs the question, why don’t WD “upgrade” back to the old versionuntil they get v4 working? They would have a better reputaion if thei rproducts worked, surely?

Happy to know that it’s working for others.

The issue is when the system is unstable, it will actually show no space in the home screen and thus the system doesn’t see that it has room to update.  Give it a minute or two (or three or four or twenty) to stablize a bit for the UI to show the capacity amount.  When it finally shows that figure, then the system will accept the firmware.

To whom it may concern at Western Digital - this latest firmware *is* unstable.  You need to take action here.  This is unacceptable customer support.

Your method worked flawlessly for me. I downgraded without problems. Only thing missing from fw v4 is LG TV Dlna srt support, but i can live without it :wink:

Worked fine for me. Thank you!!

What a difference, I just installed the MyCloud a week ago and it updated the 4.xx firmware immediatly so I couldn’t see what difference it was with the previous one. Downgraded as per your instructions and the device is A LOT more responsive, faster in access and in it’s interface…

Only must find out how to disable the constant database update for pics because I have 2 webcams attached over FTP so the disk is always updating the database but I will find out. The method as described in another posting here didn’t work for me but the downgrade is working a lot better so MANY thanks for the help!!!

Too bad WD won’t admitt something went bad with the 4.xx firmware upgrade since so many users have problems with it.

They should replace it immediatly with the old version and call it 5.xx :wink:

Regards and thanks again.

Thanks a lot!

Your instructions worked flawlessly (even though I used SSH).

4.00.00-607 was truly a dud (for me, your mileage may vary of course) and now I finally have my nice old NAS back again…

Thanks again!

A word of warning…

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.

Thanks for the tip, in my case I have no problems with the downgrading and the Twonky server…
