Hi folks,
It seems to me that you didn`t quite catch my problem. But meanwhile I solved it. Here is the solution:
I had to hold the button No 6 and 12 down, that is the both right buttons, while turning the helix on. Then the helix goes to the boot modus and the update can start.
So you see: overbearing artful dodgerness doesn`t help, but knowledge.
Have a nice day and note down
