Has anyone else found Onefinity instructions on how to revert back to a prior build?
Here is how they do it.
How to reflash the operating system on the Onefinity BB controller (Full SD card image)
i have done it once and it works. Just takes a long time and you have to get inside the controller case.
I will say that I have been runnung 1.4.0 with no problem so I’m thinking you may have something else wrong like a loose connection to the Z drive.
