Having the same issue here as well.

I can flash the firmware just fine(USA) but then when I go to flash the EMMC it just hangs up on the Waiting.

I am using the LibUSB since I am running windows 7(x86) and cannot figure out why this wont work.

I have tried taking out the battery and puting it back in when this happens and it just stays stuck on "Suitable USB device not found, waiting."

So I read it's not doable to download a XP machine on to my pc? Is there any other way to do this, doing the firmware install does nothing but reset all of my settings, I need to do a clean wipe to be happy and start over again.
