Как включить отладку по USB на Android

Включенная отладка по USB на Android устройстве может потребоваться для самых разных целей: прежде всего, для выполнения команд в adb shell (прошивка, кастомный рекавери, запись экрана), но не только: например, включенная функция может пригодиться и для восстановления данных на Android.

В этой пошаговой инструкции подробно о том, как включить отладку по USB на Android 5-7 (в общем-то, то же самое будет и на версиях 4.0-4.4), в видео показано включение отладки на Android 9 Pie и на смартфонах Samsung Galaxy.

Скриншоты и пункты меню в руководстве соответствуют почти чистой ОС Android 6 на телефоне Moto (то же самое будет на Nexus и Pixel), но принципиальной разницы в действиях на других устройствах, таких как Samsung, LG, Lenovo, Meizu, Xiaomi или Huawei не будет, все действия практически те же самые, также в статье присутствуют текстовые пути для настроек на других версиях Android и марках телефонов.

Включение отладки по USB на Android телефоне или планшете

Для того, чтобы появилась возможность включить отладку по USB, сначала необходимо включить режим разработчика Android, сделать это можно следующим образом.

1. Зайдите в Настройки и нажмите пункт «О телефоне» или «О планшете», на Samsung — «Сведения о телефоне» — «Сведения о ПО». На чистом Android 9.0 зайдите в пункт «Система» — «О телефоне».
2. Найдите пункт «Номер сборки» (на телефонах Xiaomi и некоторых других — пункт «Версия MIUI») и несколько раз нажимайте по нему, пока не увидите сообщение о том, что вы стали разработчиком.

Теперь в меню «Настройки» вашего телефона появится новый пункт «Для разработчиков» и можно переходить к следующему этапу (может быть полезно: Как включить и отключить режим разработчика на Android).

Процесс включения отладки по USB также состоит из нескольких очень простых шагов:

1. Зайдите в «Настройки» — «Для разработчиков». На Android 9, например, на Nokia — в Настройки — Система — Дополнительно — Для разработчиков. На некоторых китайских телефонах, например, на Xiaomi — в Настройки — Дополнительно — Для разработчиков или Настройки — Расширенные настройки — Для разработчиков. Если вверху страницы есть переключатель, который установлен в положение «Выкл», переключите его в «Вкл».
2. В разделе «Отладка» включите пункт «Отладка по USB», чтобы включить режим отладки по USB.
3. Подтвердите включение отладки в окне «Разрешить отладку по USB», внимательно прочитав предупреждение.

На этом всё готово — отладка по USB на вашем Android телефоне включена и ее можно использовать с нужными вам целями.

Видео инструкция

В дальнейшем, вы можете отключить отладку в том же разделе меню, а при необходимости — отключить и убрать из меню Настроек пункт «Для разработчиков» (ссылка на инструкцию с необходимыми действиями была приведена выше).

Здравствуйте! С помощью «Для разработчиков» и «Отладки USB» я удалял проблему связи, через кабель компьютер видел и изображения, и видео, и я оперировал ими. И это прекрасно!
Но есть пару но.
1. На всё время данной связи связи с интернетом не было (пока я работал с файлами через кабель, файлы, направляемые ко мне как и всегда через вай-фай, отсутствовали. И как только восстановил через Google связь, файлы гурьбой прилетели).
2. Второе но — после восстановления интернета связь через кабель с компьютером опять отсутствует. Как и ранее.
Есть ли вариант разовой настройки на связи одновременно и с интернетом, и компьютером по USB навсегда, кто знает?

Correct Answer: How to Enable USB Debugging on Android with Black Screen

by Sophie Green Updated on 2021-07-02 / Update for Android Tips

If your phone’s screen has gone black, there really is not much you can do with your phone. This means you cannot even access the data stored on your device. However, you can use a tool called ADB to get data off of your device and on your computer. To do this, you need to learn how to enable USB debugging on Android with black screen.

USB debugging must be enabled in order to perform actions on your phone from your computer. This guide takes a look at how to enable USB debugging on Android with broken black screen using a couple of different ways.

Part 1. Enable USB Debugging on Android with Black Screen Using ADB Command

One of the ways to enable USB debugging on your Android phone with a black screen is to use an ADB command. There is a command that you can use with ADB toolkit and that should help turn on the USB debugging option on your phone.

The following describes how to enable USB debugging on Android with black screen through computer.

Download the ADB toolkit for your computer and extract its contents to a folder.

ADB requires you have USB debugging enabled on your phone. Since your phone has a black screen, reboot your phone into recovery mode to accomplish this. Press the Volume Down and Power buttons at the same time to enter recovery mode.

Connect your phone to your computer, open a Command Prompt window in the ADB folder, and type the following command.

You should see your device listed there. Run the following commands one by one.

Use the following command to pull the persist.sys.usb.config file from your phone to the PC.

adb pull /data/property/persist.sys.usb.config C:\Users\[your-username]\Desktop\

Run the following command to send the file back to your device.

adb push «C:\Users\[your-username]\Desktop/persist.sys.usb.config» /data/property

Download the build.prop file from your phone by using this command.

adb pull /system/build.prop C:\Users\[your-username]\Desktop\

Launch the build.prop file in a text editor like NotePad++ on your computer, and add the following code to it.

Save the file and transfer the file back to your device using this command.

adb push «C:\Users\[your-username]\Desktop/build.prop» /system/

Reboot your device using the following command.

You are all set. Your phone will boot up with USB debugging enabled.

Part 2. Enable USB Debugging on Android with Broken Screen Using OTG Cable and Mouse

If your phone has support for OTG, then you can actually plug a computer mouse into your phone and use it to navigate around on your device. This way, even if your phone has a dysfunctional black screen, you can still perform various actions on your phone. The following shows how to enable USB debugging on Android with a black screen using a mouse.

Connect your mouse to your Android phone using the OTG. Make sure your phone supports the OTG feature.

Back to About phone section andyou should find the USB debugging option. Click on the option to turn it on.

USB debugging is now enabled on your device.

Part 3. How to Recover Lost Data from Android with Black Screen

When your phone’s screen goes blank, it prevents you from accessing the data stored on your device. If you want to view your phone’s data, one way to do that is to recover the data to your computer. Tenorshare UltData for Android helps you do just that. This little tool allows you to scan your device for recoverable content, and then it lets you restore that data over to your computer. The following shows how this tool works.

Run the aforementioned program and click on the Recover Lost Data option.

Plug-in your phone to your computer using a USB cable. Ensure USB debugging is enabled on your device.

Click the Start button to scan your device for recoverable files. In this case, we will only be recovering photos from your device.

You will see the photos you can recover from your phone. Tick the ones you want to get back, and click Recover at the bottom-right corner. The tool will recover your chosen photos for you.

You can now view your phone’s photos on your computer screen.

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.
