Twonky Forum

I have never downgraded my wd mbl firmware or had a need to
not sure if is even a good idea in some scenarios
but the question did come up in another forum
In which the previous version had twonky 5.1 and now he has twonky 5.1.9
he wanted to go back to 5.1

It got me to thinking, about where and how one would do that
WD does not make it easy to get links to the older firmware
not sure if these are also applicable to the wd mbl duo

By reading the current release notes for apnc-021109-053
I was able to do some searching to find links to all the known firmware files
