Hmm I must say I'm a bit skeptical to involve a 3rd program. The phone is not dead per say but gives a conf. error when started. Would this SEtool2 fix this and make it operational?
Don't be sceptical, many people had same problem (configuration error when phone started after flashing with xs++) and SETool fixed that. beto_nl is telling it right, I fixed my w700 doing same thing month ago :)
