The blank screen doesn't tell you too much. The device may be broken or just waiting for a flash update. If you reset it and turn it on afterwards and it responds to MySamba, then it was in the boot loader. If not, you should be able to force it into this mode by pressing ERASE on the cable and ON on the keyboard at the same time.

A possible cause of failure might be the wrong flash image. The _xtal and _ir images only work on a modified unit that has a working quartz crystal. The switch to the crystal oscillator is done very early in the startup process before the display is initialized. If the oscillator does not come up correctly, the device hangs.

If you have a crystal you can still flash the default image and try the ON+D, ON+C+C sequence as a test if it is working properly.
