    I have a LG G2, and I can not find the developer options.
    I can not find the second option you are talking about “BUID NUMBER”
    Perhaps I am not in the right part “Go to About Phone section of Settings.”

    Thank you very much for your help

    My problem is that I am not able to connect my LG G2 to my LAPTOP Windows XP
