Same error here. Any ideas on what might be causing this? I never had any problem flashing 2005 images with the old flasher. Very disappointed right now b/c I have no other machine to use to flash my 770.
1) Good connection to Mac, direct to USB port (do not use keyboard or hub) with original Nokia cable. 2) All apps shutdown except for terminal, screen saver/sleep shut off. 3) Card removed from 770 (this is a gotcha!).
