MyCloud Home as Sonos NAS stopped working

[NoPlex]

@NoPlex

Yes but not officially supported, one could clone a disk image from an earlier version such as 7.16.0-220 to the MCH but 99% of the home users are not going to do that when the new firmware is a lot more secured, disk transfer speed a lot faster and operable without internet access than the old.

For completeness of discussion, one could back up the first 23 partitions of a MCH from an earlier firmware and use that as recovery. For example, the instruction can be found here (but again 99% of MCH home owners are never going to do this)

Install Debian on WD My Cloud home

If possible, reset to factory/default settings, make a backup of the firmware (sections 1-23), according to this instruction
