I'm having a similar error. It reads avrdude: stk500_getsync(): not in sync: resp=0x30
I've tried swapping out the usb cable, and switching board and port connections. I'm running an old operating system, OS X.4. Is it my FTDI that's gone bad? Just like above, the lilypad is running the last successful upload. It might also be worth noting, the FTDI doesn't recognize if there's no board attached during the upload process. Also, it will blink the red and green LEDs on the FTDI when first plugged in, but no LEDs light up when the program is uploading. If I reset the lilypad, the onboard LED will blink once. I guess that's the bootloader.
