Mine always seems to drop a connection while flashing, but always works the 2nd time around (after I pull the battery). I blame WMDC (Windows7) as I have no problem flashing with XP on my laptop. Also, try a different USB port. I sometimes have better luck with ports built into the motherboard (back of case) as opposed to the wired ones on the front of the computer case. Just suggestions.
Try flashing to the stock Verizon 6.5 ROM and see if that works. It's actually pretty decent and atleast if you brick your phone, you can blame Verizon (can you?).
