I've been trying to update my 30K firmware without success.
Tried different Windows and Mac PCs but it always stops at 20%.
Contacted Sena several times but they say it's due to a problem in the mesh ship.
I don't this this souldld be the case as we can find several similar cases reported in the web.
BTW, my device's mesh intercom is working perfectly.
Very poor support from Sena...
