    Thank you for the article. Can you please tell me wich recovery image you have chosen (… flash the clock work mod recovery in your SONY Xperia Pro device…)? The app keeps telling me not to know my Xperia Pro (ICS 4.0.4. / 4.1B.0587). It’s rooted and seems to be ok so far.
    I would really appreciate your help!
