I pulled the memory card (SanDisk 128gb 100mb/sec) and put it in the computer. It worked fine. Tried updating via a .bin in the memory card the unit and got a blue light very fast then constant blue light. Sat for an Hour and would not reboot. Does not work at all now.Have you checked if the memory card are working ? those little suckers can pack it in fast if you are unlucky.
H2testw are a nifty little program to examine memory cards if it work correct.
