How to downgrade FW Version "02.11.12-060 : Core F/W"?

How can I downgrade the WD withdrawn FW in my system from “02.11.12-060” back to the latest release “02.11.09-053”?

Or do you know where I can download the withdrawn FW “02.11.12-060”, if anyone still has the file maybe I can copy it from you?

Thanks in advance,


Not possible to do a downgrade.  If the 2.11.12-060 was removed they should have reasons for it.  My advice is to wait until a new version is released.
