• What is USB Debugging mode on Android. How to properly enable USB debugging mode on Android: the most effective ways

    Good afternoon. It often happens that we need to check our device with the Android operating system using a computer. Be it general testing or routine diagnostics to look for any deficiencies. To do this, you need to enable the so-called “USB Debugging” mode. No matter how scary it may sound, it is actually very simple and accessible not only to gadget gurus, but also within the capabilities of the most ordinary beginner. What is Android USB debugging, how to enable this USB debugging via PC on your Android, we can learn from our article.

    Let's say right away that connecting to our personal computer is much preferable than working with a PC emulator.

    Just in case, we are inserting a short video instruction on how to set “USB Debugging”, but below we will talk in more detail about all the methods and rules of this procedure.

    What needs to be done and in what order

    In most cases, the USB debugging mode we need, for all manufacturers, can be found and set through the “Settings” menu. It usually contains the “Development” or “For Developers” submenu. And although we are not any developers, we still boldly find the desired “USB Debugging” there and, without further ado, check the box there.

    You might think that this was the end of all our ordeals, but that was not the case. It is quite possible that your menu does not have such an option. These are the times. This is no longer for me, but for the real developers. Why did they do this? Not clear. Maybe not everyone can rummage through the device and mess things up.

    The easiest way to enable USB debugging

    If it’s not on our menu, then we’ll try to go a different route. Several types of obtaining debugging via USB on different Android OS. If you have Android 2.2 3.0, then let’s first try to enter the same “Menu”, then to Settings, then to “Applications”, then to “Development”. It is quite possible that the “USB Debugging” item will already be there.

    For everyone Android owners 4.2 and above, the following very cunning way was invented. Again we go to “Menu”, then to “Settings”, to “About smartphone/About tablet”. We find here “Build number » and perform some shamanic actions. We click on it 8-10 times and the next time we go to “Settings”, “For Developers” and “USB Debugging” suddenly appear. All that remains is to check the box again.

    Let's assume that we succeeded and this debugging is enabled. The first time you connect to our PC or enter any command, you will be asked to trust the computer in at the moment connected. So we completely trust our computer, then check the box and click “OK”. All. Debugging is enabled. If suddenly the computer does not want to detect our device, then try the following. Check if your smartphone/tablet is suddenly blocked. Unblock it, check the debugging again.

    If it still doesn’t work, try updating/replacing/reinstalling USB drivers on your PC. Note: It is advisable to use only a USB 2.0 port and not a port like USB 3.0. Still, I dare to be sure that everything worked out for you and the USB setup mode has turned on.

    Option one (relevant for most versions of Android OS).

    First, you need to enter the settings menu. After that, find “Development” in the lower items and check the “USB Debugging” box.

    Option two (relevant for most tablets)

    Here the algorithm of actions is identical to the first option, with the exception of the “Development” item. In Android OS versions below 2.2, this item is called “For Developers”.

In such a situation, a method that involves using recovery mode will help you. It is worth noting that to implement this, a custom software must be installed on the smartphone. Recovery CWM or TWRP. This will allow you to get root rights access to the mobile phone operating system.

    • From the official website, download and unpack the qtADB-cwm-edition application into the root directory of the computer operating system.
    • There, create a folder called SQlite3_Windows and install the pre-downloaded SQLite relational database into it.

    If none of the methods work

    Let's consider what needs to be done if ADB does not see the mobile device. First of all, you need to check the software component, which may involve using unofficial firmware or not suitable adb drivers. The OS version can always be downloaded from the manufacturer’s website, and the required software from Google website. Another reason why debugging from a computer does not work is using damaged USB cable or connector. You can check this by connecting your mobile phone using a different wire and into a different connector.
