Hi and thank you very much for your offer . Actually I've two of them in my hands, so it wouldn't be a problem to extract the working recovery from the other phone, the problem is that the tutorials that I've found are very complicate. I think that the best option for me is to wait for the right recovery (CWM or TWRP) to appear, than I'll load it like I did for the wrong one, that actually is not exactly "wrong" because it has been accepted without errors. As far as I'm concerned it could be that I loaded the recovery that is not for the wcdma version, this phone is a 1SW version. The phone is not bricked, it only lacks the recovery and because it's not rooted, there are few things that I can do, if not to wait for the development of this version. The phone is very good so I've no doubts about its development.
