somehow I've managed to screw up my CE. Since I wanted to try an wifi dongle, I downloaded the new image from Jookie's web (rpi-ce-run.img). I dd'ed it onto the internal card, everything fine.
Now, I boot the CE, wait a few sec as usual... I see the blue LED flash which indicates everything is OK but then after another couple of secs I see again all the LEDs flashing orange like nothing has happened. And of course, CE_DD & friends don't load, the desktop is empty.
Any idea what I did wrong?
EDIT: just to be on the safe side, this is what I did:
sudo dd if=./rpi-ce-run.img of=/dev/sdb bs=1M
