Buy a used MyCloud with OMV Firmware

Good evening,
i buy from ebay a uset MyCloud but instead of default firmware i found OpenMediaVault.
Is possible in some way to restore the original firmware?

Thank you

Use the forum search feature (magnifying glass icon upper right) and search for “unbrick”. There are many past discussions on restoring the My Cloud operating system to a hard drive. There are a number of methods that can be used to restore the original firmware to a single bay/single drive My Cloud device. The unbrick methods discussed in this subforum generally are for only the single bay/single drive My Cloud device.

If you have a multi bay/multi hard drive My Cloud device or a My Cloud Home then see the dedicated subforum for that device.

The following directions are from user Fox_exe and many have used them to restore the My Cloud OS to a existing or new hard drive. Because there are two different single bay My Cloud versions the unbrick method is different for each. You cannot restore a first gen v3.x/v4.x My Cloud to use the newer second gen v2.x firmware. Check the P/N number on the bottom of the single bay/single drive My Cloud enclosure. P/N that ends with “-10” is a second gen v2.x firmware single bay My Cloud. A P/N that ends with “-00” is a first gen v3.x/v4.x firmware single bay My Cloud.

The main Fox_exe repositories for multiple My Cloud models can be found here:
