Exactly how do you update the DM42 Firmware?

I think it would help if you, zeno, write a list of steps that you followed and where you got a problem.

Picking out this or that step in a flood of replies is confusing.

Something like.

- I did A
- then I did B
- then I did C
- ..
- ...
- at M I got stuck, with this error: error_description .

It can be also useful for other people that may end up in your same situation.
