Apparently (from my failed experience) one of the requirements of this technique is the phone needs to be already rooted.

If that's the case, it'd be great to have it added to the first post.

Thanks

The QPST Configuration tool worked as a charm without any errors whatsoever. I have just one query. The XQCN file generated is 989 kB in size. Is that the right size? If not, what size should it be?

Same problem here.

The backup stops forever at 99%
I also tried to change port but the problem remains.
The Drivers seems to work.

I tried twice and the result was the same, a 1074kb archive.
