      You will have to learn mobile phone repairing. get enrolled in some good institute. If there is no institute in your local area, then join some online institute and learn with the help of their CDs and other study material. Remember, Practice make a Man Perfect.

    Dear Sir,
    I am using rail tracking application in my mobile. Which has three modes of tracking train.
    1. Cell Tower Information(use inside the train only) yes/no (work in offline mode)
    2. Internet
    3. GPS(use inside the train only) yes/no (work in offline mode)
    The developer has updated the cell tower information. Since updating the cell tower information the application is not working accurately as it was working before updation. How Can I get correct information of train in Cell Tower & GPS mode ?

      As far as hardware is concerned there is no difference, only upgraded versions of CPU, GPU, Sensors,RAM etc etc which is not easily available in India for replacement. Rest speaker, ringer, mic, vibrator, Touchscreen, display, Combo display, charging connector, handsfree connector, changing strip etc., you have to practice properly.
