Enable USB Debugging and OEM Unlocking in Developer Options

One of the things that make Android distinct as an operating system for mobile smartphones and tablets is its being an Open Source platform that encourages developers to engage in various types of development activities. And the one feature without which the custom development would not have been so easier is the availability of the “Developer Options” that is found under Settings of all Android devices by default.

These developer options contain advanced features that help any person with a developer’s bent of mind build, test, debug, and package Android apps and mods. In simple terms,  developer options allow quick access to and Android device from a computer via ADB (Android Debug Bridge) commands.

Features of Developer Options

The “Developer Options” feature is indispensable to Android developers, hackers, and enthusiasts as a means to quickly access and control their device from the PC. Even if you are an average user and wish to root, install a ROM or mod on your Android device, you must turn on USB Debugging mode on your phone or tablet. And you’ll not be able to do it unless you enable Developer Options on your device first.

Among the most useful features that are  found under Developer Options are as follows:

  • Enable debugging over USB.
  • Quickly capture bug reports onto the device.
  • Show CPU usage on screen.
  • Draw debugging information on the screen such as layout bounds, updates on GPU views and hardware layers, and other information.
  • Many other options to simulate app stresses or enable debugging options.

The “Developer Options” has always been visible by default in all previous versions of Android. On

Developer Options on Gingerbread (Android 2.3):

Settings> Applications> Development> USB Debugging

Developer Options on ICS (Android 4.0):

Settings> Developer Options> USB Debugging

Developer Options on JB (Android 4.1):

Settings> Developer Options> USB Debugging

Enable Developer Options and USB Debugging on Android

In fact, the developer options lie at the core of Android development and so they cannot be removed as long as Android is an open source environment. The only change Android 4.2 brings in connection with these useful options is that now they are hidden by default and you will have to make it available by doing some finger exercise.

  1. Open Settings> About device> Software info on your Samsung Galaxy phone or tablet.
  2. Now scroll to Build number and tap it 7 times.
  3. After tapping the Build Number 7 times, you will see a message “You are now a developer!” or “Developer mode has been enabled”.
  4. Return to the main Settings menu and now you’ll be able to see Developer Options. Open it and you will find OEM Unlock and USB debugging options there. You can now enable or disable the options.
  5. Tap on Developer options and mark the box in front of  USB Debugging  to enable it.
  6. To disable USB Debugging mode later, you can uncheck the box before the option
  7. To enable Developer Options, go to Settings> Developer options and tap on the ON/OFF slider on the top of the page.

Enable USB Debugging on HTC Devices

If you own an HTC One, HTC One Max, HTC One M8 or any other HTC phone with Android 4.2, 4.4, 5 or 6, here is how you can turn on the Developer Options on your device:

  1. Open Settings> About> Software Information> More.
  2. Then tap “Build number” seven times to enable Developer options. Finally, you will see “You are now a developer!” message on the screen.
  3. Go back to the Settings menu and now you’ll be able to see “Developer options” there.
  4. Tap it and turn on USB Debugging from the menu on the next screen.

It is not obvious why Google decided to hide the “Developer options” on the latest version of Android. I guess they might have done it as a warning for noobs but whatever the reason might be, you can easily turn on the Developer Options and enable USB Debugging mode in a fun way using the above method.

Enable Developer Options on LG Devices

If you have an LG device, LG G2, G Pro 2, LG G Flex etc., you can enable the Developer options from Settings> About> Software Information, and then tap Build Number for 7 times. You’ll see a toast with “You are now a developer!” message. Now go back to Settings menu where you will see Developer options, tap it and enable USB Debugging. Here’s a screenshot from the LG G3:

  3. Lucifer believe me I have been tempted to spike my LGL15G Sunrise more than once in the past 24 hours. It got hung in a boot loop literally on the anniversary of my activating it , shut down as the warranty expired. The Smart Talk rep said sorry nothing we can do other than sell you a new phone that we can transfer your account balance to if you choose to buy and continue straight talk service. Not only do I have the boot loop, I also have the McAfee Kill switch that stops a factory reset, bootloop is stopping me from getting to settings, where I could turn on USB Debugging, giving me a window to the software, and access point to repair the thing. I’m thinking about telling Straight talk and McAfee both that I’d be fine if they stuck their LG Sunrise where the sun don’t shine.
