Hi,
Please try to make it clear... you're hard to follow .

You read this page right ?
http://ixox.fr/preenfm2/build-it/burn-firmware/Looks like dfu-util moved to
http://dfu-util.sourceforge.net/I just updated the page with correct links.
ok i got dfu-util and command line utils from apple installed. im stumped. i think im supposed to have a directory on the thumb drive called pfm2 with the bootloader and firmware in it and when i try to CD over to that folder it says no such directory.
OK so you flashed it with the dfu-util command ?
Did 'dfu-util -l' list any device ?
Did the dfu-util show a progress bar while flashing ?
You flashed both firmware and bootlader ?
i can also hook up USB to the cerb40 and flash directly right? how do i do that? i need it spelled out my apologies but i just dont ever do this or anything remotely similar... the instructions are like french to me. no pun intended. well ok pun intended
. i only speak english
When flashing the CERB40 for the first time, you don't have any choice.
Put on JMP3 and plug the CERB40 directly to your computer with a mini-USB cable....
when i plugged the unit into my xp machine it wanted a driver so that means it works right?
I would say that's rather a good sign.
also, when i plug usb or 9v power into the unit and the jmp3 is not closed, the LED lights light up dimly. is this a bad sign? the screen has never come on once yet. i wish there was another indication that something was working.
Yes if it makes some sounds, it works

Do you hear a small pop when switching on ?
Any picture of your PCB both side, to see if anything is OK with the Display.... What display do you use ?
