Try this:
Apply power to your receiver. wait until the white light has been on a couple of minutes, then press press the red power button on the remote. The white light on the receiver should blink and the box should boot in a couple of minutes.

i take it this is a genune vu box and not a clone nodel?
if it's not then flashing the latest images will cause problems
if your sure it's a genuine model i would keep flashing the image
and if you have anouther usb stick forrmat that to fat32 and try
with it as your usb stick could have a problem, for me vu genuine
vu boxes are bullet proof..i had the same issue and my mate told me to bully the box.this way
first choose a image of my choice and flash the box and keep flashing
the image untill the box cleared i flashed the image five or six times
then it cleared and worked as normal.
