How to Enable USB Debugging Mode on Android

The ways to enable USB Debugging mode, which is accounted for the key step in Android rooting process, vary from one Android version to another. USB Debugging is required by adb, which is used for rooting, backing up, installing a custom ROM, tacking screenshots from computer and more.

First, you need to enable «Developer Options Menu».

Tap the Build number field seven times to enable Developer Options. Tap a few times and you’ll see a countdown that reads «You are now 3 steps away from being a developer.»

When you are done, you’ll see the message «You are now a developer!».

Tap the Back button and you’ll see the Developer options menu under System on your Settings screen.

Now, you can enable USB Debugging mode.

1. Settings > About Phone > Build number > Tap it 7 times to become developer;
2. Settings > Developer Options > USB Debugging.

Warning USB Debugging should only be enabled when you need it. Leaving it enabled all the time is kind of a security risk for that this mode grants you high-level access to your device. Say if you connect your Android phone to a USB charging port in a public location, the port could use the USB access to your phone to access data on your phone or install malware. This could happen when and only when USB debugging mode is enabled.

To disable USB Debugging and other developer options when you don’t need them, slide the switch at the top of the screen to OFF.

Can We Enable USB Debugging using ADB Command?

If you’re looking for a way to enable USB debugging and Developer options using an ADB command, you must be in a desperate situation. If you are in a situation in which the only way to save your phone is to turn on Developer options or USB debugging from PC when the phone is locked. So, the question is, can we enable USB debugging using a command from the computer, or is there a USB debugging enabler tool for available for phones with a broken screen?

I found that question in the comment posted by one of our users. Though I already knew that it’s not possible to enable USB debugging using ADB commands on Android devices with a locked or broken screen, I decided to do research. Having spent hours on Google searching for some miraculous workaround, I came across some people claiming to enable USB debugging using a command on their broken device.

Can we Enable USB debugging from PC?

Well, the obvious answer is a “no” and here’s the explanation. We all know that ADB requires authorization from an Android device in order to communicate with it. It’s only by allowing the USB debugging and validating the computer’s RSA key fingerprint that we let the ADB daemon connect to our phone and control it. This is a security feature otherwise anyone who gets a temporary possession of our Android phone can easily manipulate it.

It’s only in the Android Recovery Mode when the Apply update from ADB option is enabled that the ADB daemon can detect your device regardless of whether or not USB debugging is active in the device Settings.

However, if you try the ADB shell commands, you’ll get the following error in return.

If you have a rooted Android device and have TWRP recovery installed on it, there are better chances that you can successfully mount System and Data partitions using ADB commands.

Please note that Fastboot doesn’t require USB debugging enabled. You can boot your device into the Fastboot Mode and try

fastboot oem unlock

The oem unlock command can unlock your phone’s bootloader but in doing so, it’ll also perform a factory data reset.

Enabling USB Debugging using ADB Command

Github user Pantasio claims he was able to enable USB debugging via Recovery Mode using ADB commands. I am not sure if the allegedly working trick described Pantasio will work for you or not, but it certainly didn’t work on my unlocked Samsung Galaxy Note 10 Plus. Obviously, I turned off the Developer options on my phone before following his steps. If you still want to give it a shot, follow the instructions.

Now, let’s come to the steps to enable USB debugging using ADB commands on devices with a broken or damaged screen. The method described below will work only on Android devices with an unlocked bootloader.

1. Boot your Android device into the Recovery Mode.
2. Download the latest SDK Platform-tools.zip and extract it.
3. Open the ‘platform-tools‘ folder and launch a command window by clicking on File > Open Windows PowerShell in the folder window. In case you have set up system-wide ADB and Fastboot, you can launch the command window from any screen of your PC.
4. Anyway, type the following command and press the Enter key.
5. If you get the device ID as an alphanumeric value in the command window, it means that your ADB can detect your device in the Recovery Mode. (Lucky you! :D) I could not get past this step.
6. Now type adb shell and hit the Enter key. After that, execute the mount data and mount system commands to mount the respective directories on your device.
7. Now, you have to pull the persist.sys.usb.config file from your phone to the PC. To do that execute the following command. Don’t forget to replace the location where you want to save the pulled file with yours.
8. Open the persist.sys.usb.config file with a text editor and edit it to “mtp,adb” and save it. Now use the adb push command to send it back to your device.
9. It’s time now to download the build.prop file of your device to your PC.
10. Open the build.prop file with a text editor like NotePad++ and add the following lines to it.
11. Save the file after you have made the above changes to build.prop and push it back to your phone using the following command.

If you followed every step carefully and didn’t miss anything, USB debugging should be enabled on your device. You can now reboot your phone to the system using the following command.

Your phone will boot up with USB debugging enabled but there’s a catch here! Next time, when you try to run ADB commands, you’ll still have to allow USB debugging or verify the RSA key fingerprint on your phone. If you are somehow able to see the RSA notification on your phone’s display, tap on OK.

Disable USB Debugging using ADB Command

Well, enabling USB debugging on a device with a locked or broken screen might not be possible but you can easily disable is using an ADB command if it’s already enabled. I tested it on Samsung Galaxy Note 10 Plus, Redmi K20 Pro, Galaxy S20, and OnePlus 8 successfully. This should work on all Android devices regardless of the manufacturer.

1. Launch the Command Prompt or open a PowerShell window. You can do that in 3 ways.
2. Connect your device to the computer and execute the following command after running adb shell .

Now go to Settings > Developers options and you will find that USB debugging has been disabled.

Turn off Developer Options using ADB Command

Disabling the Developer options on Android on a normal device is very easy. However, if you aren’t able to navigate to the device settings and want to turn it off, there is an ADB command for that too.

1. Open a command window on your computer.
2. Connect your device to the computer via a USB cable.
3. Type adb shell , press the Enter key, and then issue the following command to turn off the Developer options on your Android device.

As soon as you hit the Enter key on your keyboard, Developer options will be turned off on your Android device.

That’s it! To check whether you have successfully turned off Developer options using ADB command or not, go to device settings.

Thus, we saw that enabling USB debugging using ADB command is not possible because USB debugging is the very thing that facilitates ADB to interact with and Android device. That’s why I always advise people to turn on Developer options and enable USB debugging on their Android phone or tablet as it could be a life-saver in certain tricky situations.
