Have you tried the v273 pre-release for QS 2.0?

If you still can't update the firmware after that, it might be time to drop an e-mail direct to Pangolin.
Other things you might want to try (yeah, I'm reaching here!):
* Re-seat the memory card
* Re-seat or try different USB cable
* Temporarily disable antivirus software before trying the firmware update.
Good luck - let us know what you find out!!
