Downloading to a flash drive - I don't think this is actually transferring consciousness. Flash drives are just copies.
To survive the process, you would have to initially be plugged into something that is capable of acting as a full extension of your brain. You would then become simultaneously "one" with the device, as well as your current brain. Then somehow, your current brain functions would need to cease working, and you would be fully reliant on the new "brain."
From there, that process in reverse would bring you to a new body.
