Enabling USB debugging mode on Android 4.2

Android is the world's most used operating system and the main feature that everyone loves about it is its openness and ability to be customized. If you too like playing around with custom ROMs, rooting methods or such things, then you are most probably not a stranger to the 'USB debugging mode'. As many of you might know, the USB Debugging mode was actually intended for those people and developers who do not really know what they are doing and have a chance of bricking their device. To stop people from accidentally putting their devices at risk, Google has hidden the USB debugging mode option with the launch of Android 4.2 Jelly Bean. But as it turns out it is still very easily possible. Lets find out how.

Step 1: Go to Menu of your device and then go to Settings -> About Phone  (if you are using a phone) or Settings -> About Tablet (if you are using a tablet) in your device.

Step 2: Now in the About screen scroll down to Build Number. Tap on it Seven times. When you tap seven times, a pop up dialogue saying "You are now a developer!" will appear on the screen and voila, you have surfaced the USB debugging mode and other developer options back.

Now to activate USB debugging mode, all you have to do is go to Settings -> Developer Options -> Debugging and check the USB debugging option.

As you can see, discovering this hidden option isn't quite that difficult and the best thing about this is that these "new" developer options now remain uncovered and you can enable or disable them at your ease and need.


  1. It is really helpful that by this USB Debugging Mode I could connect Android applications device and computer with Android SDK. Even I can mount my android phones to my computer to transfer files without causing any kind of hurdles.

  2. My USB debugging option is grey, and aI can't select it. Ideas why?

    1. Did you complete the steps as shown above correctly?

    2. Your USB debugging option is grey. dont worry. You need to scroll up on the screen and turn "ON" developer options.

  3. My phone is Note 2 (GT-N7100). Its showing error " Firmware upgrade encountered an issue"
    and it is going only in odin mode how can i Enable debugging mode because i need it to restore the phone.
    please help

  4. Can we enable USB debugging from PC... Screen is locked in phone. So, I can't access phone to enable it.... Files won't show when mobile is connected to pc through data cable.
