I bought LG G Pro 2 in India. The phone is Korean made and when i used factory reset mode by pressing volume key and power key, i see Korean language. How to change the language from Korean to English. Please help.
You cannot. The phone's default language is Korean and the only way you can switch language at this level is to flash an English ROM.
Look on YouTube for videos about rooting the LG G Pro 2. Some of these videos should display the fastboot screen. The ordering of the menu item should be the same for all language - so you can make good guesses of which option is which without knowing Korean.
