I carried out the repair successfully partially following this guide. I am an experienced technician and have carried out several similar repairs. I have damaged the screen only on one occasion. I usually do not remove the lcd completely but only de-glue/separate the bottom part of the screen from the frame to make enough room to remove the daughterboard flexes (soft buttons). A safer way to separate the screen is use a thin laminated playing card and insert it gently, after applying heat, in between the frame and LCD assembly from the back of the LCD instead of using a pick.
