Is there a Verizon stock ROM? If there is you may be able to put the .nbh file on the stock 512mB micro card and rename it VOUGIMG, then put the card in and go to bootloader mode. It should automatically flash the stock ROM. I just did this with my Sprint Touch when the usb port stopped working. Of course, I could still see the screen. It may not matter if they can't see the screen either, then they should just replace it.
Edit: here is the Verizon ROM

extract the .nbh and do what I described and it 'may" work.
