Can I downgrade the firmware to 2.1.92 please?

Hello,

I own 3 WD Sharespace - 2x4TB and 1x8TB - and recently  [made the mistake of] upgrading two of them to FW 2.2.93.

Results : inacceptable transfer rates, hangouts during reads (NFS or SMB), abrupt restarts… The boxes have become unsuitable for their purpose - serving video files to a media player - and at this hour I’m not even sure one of them will ever complete start up again.

I have read this forum.

=> Can I, and how, go back to firmware 2.1.92? It worked fine for two years.

=> Or do I have to buy a pair of NAS servers from another company asap, and transfer my data before it is too late?

i believe that its not possible. because they dont even allow you to download it to update it, i dont think its actually possible
