Can I root, do a full back up.... Restore with ruu and send it back to htc / orange....???
Well, to advise you on that would be to allow a perception of condoning a sort of anti-carrier/user agreement ("Terms of Service") scheme.

So we can't go into a discussion on that course of action you mention in particular.
Please understand.

(no offense)
