I just got my leviathan v2 pro.

It came with an older Firmware and I am trying to update to the latest one to be able to adjust the Bass.

Unfortunately when trying to install the firmware it gets stuck at 0% without any progress and then I receive a message there was a problem updating the firmware.

Any suggestions or thoughts please? 

Help is much appreciated.

P.S. My laptop has only USB-C ports so I connected with multiple USB-C to USB-C cables (all high quality) and USB-C to USB-A + Adapter to USB-C
