Hello people,

I'm just struggling with updating my Sena 20s to the latest firmware version.

Currently I have version 1.5 on my Sena. When I want to update it to a version higher than 1.5 it gets "unplugged" and "plugged in" while updating at about 93% and then just rushing till 100% but without flashing the new version.

Did a soft and hard reset. Installing previous versions and updating to 1.5 again works fine.

Tried it with Windows 8.1, Mac OS X El Capitan and also with "Device Manager" in Version 2.9 and 3.4.2

Nothing worked....

And now my phone can't recognize the Sena anymore :-(
