Read the opening post of this thread. Especially the part with title "PREPARE YOUR PHONE AGAINST RELOCK". That should work.
Good luck,

Hello, Heathcliff74.
Thanks for answering so soon., but precisely he wanted to install Interop Unlock because with Chevron I could not have installed WP7 Root Tools (he settles but says to me that with Chevron it is not sufficient that he installs Interop Unlock) That's why I think that the problem is in having updated drivers 2 of HTC... Anyway, I am going to try it once again... Thanks for you time. Greetings.
