I would like to have all firmware updates I do would work as smooth as this one did...

Works like a charme!
Thanks DM!
Thanks Thomas!
Great stuff!
Cheers!

EDIT: Sorry...it was misleading, what I wrote:
With "all firmware" I wanted to refer to firmware updates of OTHER devices like my Arduinos or my Longan Nano, which
offer quite some challenge by times when updated...the DM42 on the other hand has been always updated like a charme.
