if you already enabled usb debugging, you can use any pattern lock remover software, it is very easy to do. here is the download link Android Multi Tools v1 02b FAISAL JEE rar ,

in case of mobiles, you want to tap on build number for 7 times to enable Developer Mode, which you can find under "About Device" (last option in settings)

you can learn these method for future if not working at this time,

Thank you.

in your android phone's settings enable or access developer options and turn on usb debugging,( if you don't know how to access developer options you can google your android phones model and android version and how to enable usb debugging) once you enable it just plug it into your laptop and it should recognize it and automatically download the correct driver, if not, go to your phones manufacture's website and look for driver downloads for your model and android version. you can also google this to save time.

go to About phone then press the Build number 5 times, like that the devlopper option will be activeted than go back & entre it and enable USB debuge

Generally, to enable hidden developer features in Android (like usb debugging):
Go to Menu-Settings-About device
Tap on "Build number" multiple times. You should start to see a message that says something like "Tap 3 more times to enable developer mode" and so on until it says Developer mode enabled. You should then have a Developer options selection available in your menu that includes a USB debugging option.

Try and do another reset and see if it changes.

I finally found it myself after looking for hours and testing.

Go to settings -> Options for developers -> Right top corner, turn it ON -> scroll down to debugging -> USB-debugging -> click it.
