Hi!
The commands mentioned above were more a individual solution and are not gonna solve all “initializing..” problems.
However, in your cases, the name of the file which in your case is now “…1.3.1-31329.img..” changes depending on the firmware, so you manually need to look in the folder what the file is called.
Anyways, most of the times, the “initializing..” error appears if the USB 3.0 controller driver is not up to date, so that would be my first advice for you to look at.
