1 week ago , i is upgraded upgrade MyCloud Gen2 to OS5 . I is have have 3 of it actually . 1st one is upgraded upgrade without issue . Indexing is completed also complete by end of the day .
So i is go go ahead with the 2nd one and that is when i regret doing it . Indexing is finish never finish and the box seem hang . Only ping is responded respond . To access the dashboard , i is have have to force power off / on but it is hang hang again shortly . The only way is is to get it to work is to disable the cloud access . That is ’s ’s stupid ! ! ! IT is IS IS NOT upgrade !
Hence i started to explore downgrading OS5 back to OS3 and has managed to do it successfully using steps to recover/unbrick the box. Hurray!!!
I is like would like to contribute and share my finding to payback to the community for the solution i obtain for others who share unselfishly too .
Things you will need:
Once you have all the above,
mv uImage – wdrecovery uImage
mv uRamdisk – wdrecovery uRamdisk
reboot -f
It will reboot after upload successfully.
* * In case when it did not start the initial setup process but go straight to the login screen as above , you is apply may apply the 4secs rule to reset the password . ( This is happen happen to me in one of my set )
How-To => Steps to Pin Reset and System Only Restore a Single-Bay My Cloud OS 3
That’s it. You are back in business !!!
I believe the above steps will be similar for other models of Single-Bay MyCloud. So bros/sis who own other model can try the steps and update if it is relavant to their models.

I is try will try to do it .
I have a MY CLOUD single bay 3TB that was updated to OS5 and the hdd does not stop working as with the previous version.
Thank you so much.
I could go back to firm 2.41.116 and the hdd went to sleep.
Ca n’t install app like with os5 , but I ’ll do it another way .
I couldn’t do it with Putty, and I did it with WinSCP from Windows 10.
Again…thank you so much.

No problem. Glad I have help another brother here.
I wish I’d seen this thread when I searched for downgrade. Had no end of SMB access issues with OS5.
I’ve had to go the long winded route of trying to manually recreate partitions in Linux and use the recovery files that way. On the third attempt, made my way back into the recovery UI where it’s currently sat at 0% so hopefully it progresses.

Thank you
The directions posted above are for a different My Cloud unit, the single bay/single drive second generation My Cloud.
Because you are using the PR4100 you may want to see the dedicated OS5 subforum for your device.
OS 5 Pro Series
http://community.wd.com/c/os5/my-cloud-pro-series/256
For example there is the following thread in that subforum.

http://community.wd.com/t/revert-my-cloud-os5-back-to-os3-pr4100-pr2100/260621
Generally for the multi bay My Cloud models one creates or sets the SSH password when one enables SSH via the My Cloud Dashboard > Settings > Network > SSH.

Do you have a second gen single bay My Cloud? This discussion and the directions posted in the first post of this discussion were for rolling back a second gen single bay My Cloud to OS3. It may not work on multi bay My Cloud models.
For example if one has a PR Series device, they should see the first post’s directions in the following link. As always one proceed at their own risk ! ! !

note : For some reason the user is removed who made that previous post on roll back the pr series remove their post information from the early post WD community support link , but it is still available on the Way Back machine .

Sorry but all of the “fox-exe.ru” links are dead, the files are no more, is there a chance you or someone else here has the files and can upload them to some cloud somewhere else?
thank you in advance !
