HOW TO ENABLE USB DEBUGGING ON ZENFONE 5,6,4,2 AND OTHER ANDROID DEVICES

welcome to the world of android

In this tutorial i will show you on how to enable the usb debugging on your device.In short let me explain what is debugging and you need to use that.Mostly we use usb debugging when updating the firmware of our mobile manually and while sideloading the firmware from adb sideload and we can also use that for connecting our device with the pc.

          The main thing is you cannot see the usb debugging option directly in the settings menu . we need to do a small thing to do that.well,i will guide you step wise on how to get that option and get that ticked

1) firstly head to the settings menu on your mobile.

2) In settings go to the about thing which will be at the last in the settings menu

3) after clicking about then select the last one which is software information.

4) after selecting the software information you can see the build number showing its build number

5) tap on the build number multiple times( 7/8 times) .while tapping the build number you can see on the bottom of the screen messages coming as you are 2 steps away ,etc.. continue tapping the build number until you see the message as YOU ARE NOW  A  DEVELOPER .

6)then next come back to settings menu now you can see the new option of developer options in the settings menu ( it wont be there if you not do the process which i said earlier ) .select developer options.

7) after entering the developer options search for usb debugging in those and tick the usb debugging option.

8) done. you have enabled the usb debugging.

    enjoy..
