I got the well known troubles with SW upgrade last november.
I opened an RMA and got a new MBL from WD (south american 1.4 version, instead of the european version that I sent them for replacement… doesen’t matter).
Now, the replacement works properly, but the UI suggests an SW upgrade at any access.
As far as I can read in the various posts here, the problems given by the 02.10.09-124 FW (“UI unreachable”, “LED malfunctioning”, “NO Sleep”) are all still reported by MANY people who havING UPGRADED THE fw.
Why WD cannot tell us WHEN there will be a debugged FW upgrade to uplad safely into the MBL?
All efforts of the community didn’t clear any of the FW mis-upgrade issues. WD seems not to be working professionally, customer oriented this time!
