The Firmware update on my Multiplus compact 12/1600/70 via VEFlash and MK3 USB Interface from Version 1906132 to 1906159 started fine. Following the described procedure I could connect and start the update without problems.
The "Busy Programming Firmware" window appeared and the counter run from 1% to 9%, when the update stopped suddenly. Now the Multiplus doesn't do anything except flashing the green charger LED fast.
I can't connect again or do anything else with the unit, so I hope for a suggestion for a solution here.
Thanks a lot for your help.
