Hi Laura I have seen strange iBOB behaviour due to an incorrectly plugged in CX4 cable. It must have been bumped at some point and, although still plugged in, was causing strange behaviour. The iBOB would report being successfully programmed but the LEDs would do strange things. Not sure if this is related to your problem though.
