Hi,
I've tried to update my DM42 firmware. So I copied the file, ejected the drive from the Mac and then it asked for confirmation which I provided.
It started updating and at this point I removed the USB cable (by habit I guess).
The screen went blank and the DM42 unresponsive to any key.
So here is what I tried:
- press Reset
- press and hold PGM, press Reset for 2 to 3 secs, release Reset, release PGM
- the same with a brand new battery
- the same with the USB cable connected
Nothing changed: the screen is still blank.
Is there something I can do?
P.S: I sent an email to SwissMicros but no answer yet.
DM42 really bricked

I got an email from SwissMicros and fixed the problem with dm_tool. I'm impressed that it worked. It is really well designed.
And the answer was perfect too.

I don't know what the screen is supposed to look like in Bootloader Mode. Does sudo dfu-util -l find anything?
