I've done the same thing, and I agree about the placement. Luckily I
never changed my code away from the default.

Just for encouragement: flashing should let you into the phone again.
It doesn't reset the code, but once you're back into your device, you
can try to recover the lock code using this program:

It looks like you're doing everything correctly. Be sure to run
flasher before plugging in the N900. It will wait for you to plug it
in. Normally, when everything is working, pressing U is not necessary,
as N900 will detect flasher's commands and just start going. (Pressing
U certainly doesn't hurt, though.)

You might try enabling or disabling R&D mode with the flasher, and
then trying to flash again after that. I've read reports in the past
where people having flashing trouble were able to get it going again
after issuing those commands.

There is also the "cold flashing" technique, to replace the boot
loader. (I have not personally tried it.)

Good luck!
