My Cloud -10 Will Not Boot After OS 5 Update

I updated from OS 3 to OS 5 and now my My Cloud will not boot. There is just a rapidly blinking blue light on the front. I have let it try to boot for over 24hours and it will not. When I go to it wants me to update to OS 5 again, but when I try, it can not detect my My Cloud. I can not access the Dashboard. It can not detect my network. I have tried the reset button, but it does not work either.

I have heard you can install Linux in Windows 10 to get your data off the drive, but I do not know how to do this.


Please refer to this KB article: Blinking White or Blue Power LED on My Cloud

If all other methods fail (on a single bay My Cloud), one can extract the internal hard drive from the My Cloud enclosure. There are a number of videos on YouTube showing how to do so. Once extracted that hard drive can be connected to a computer using a USB to SATA adapter, or a USB to SATA docking port, or a spare SATA adapter on the computer. To read the files off the drive (EXT4 formatted partition on the drive) one can use either a Linux distro (Ubuntu is one popular distro), or a Linux Boot DVD/USB Flash Drive, or third party Windows Linux drivers. There are a number of free and paid programs that will allow Windows access and read a Linux formatted hard drive like the My Cloud’s hard drive.

After extracting/copying off ones data one can try using one of the various “unbrick” methods to restore OS3 to the single bay My Cloud hard drive so it can be used again within the My Cloud enclosure. Note that the OS5 supported second gen single bay My Cloud uses different unbrick directions than the first gen single bay My Cloud which does not support OS5.

There is no way for me to find out what the alert code is with the method you described. This is because I am unable to access the Dashboard. The My Cloud will not connect to my network. Everything else on the network is working as it should. Just not the My Cloud.

Thank you for your reply.

Mine is the second gen single bay My Cloud. It has a 4GB Red NAS Hard Drive in it. You mentioned “if other methods fail”, I can go the Ubuntu route. What should I try out before resorting to one of the Linux fixes?

Various troubleshooting steps and things to try if you cannot access the My Cloud dashboard.

  • Due to the indexing the My Cloud OS5 does at OS5 firmware install it could take days for the indexing to complete on devices like the single bay/single drive My Cloud, so just wait and see if the indexing completes.
  • Try using a new Ethernet cable to connect the My Cloud to the router.
  • Try connecting the My Cloud, using the Ethernet cable, directly to a computer with a networking port.
  • Try using a different networking port on the router.
  • Try a 40 second reset (will not remove user data but will reset My Cloud settings to default) using the reset button on the back of the My Cloud.
  • Use the forum search feature (magnifying glass icon upper right) and search for similar discussions to your issue (if you haven’t done so already). Its possible one of those other discussions could have a suggestion that may work.

For example, a possible fix one person did for their unit that had a blinking blue LED. Use such methods at your own risk.
