Where in Xiaomi debugging on USB: hidden settings and launch ADB

Enabling USB debugging is a fundamental step for any Xiaomi smartphone owner who wants to gain extended control of their device.This feature gives access to the Android Debug Bridge interface (ADB), allowing you to transfer commands directly to the operating system, install applications to bypass restrictions, make full backups or even reflash the gadget. Without activation of this mode, many advanced diagnostic and system modification tools will remain unavailable to the user.

In the standard settings menu, the option is hidden from the eyes of the average user to prevent accidental interference with the system, and can only be found after unlocking a special section for developers. The activation process may vary slightly depending on the version of the MIUI shell or the new HyperOS, but the overall algorithm of actions remains the same for all current models.

Next, we will discuss in detail where exactly in the Xiaomi menu is debugging over USB, how to properly turn on the developer mode and what nuances should be considered when connecting a smartphone to a computer. Without USB debugging enabled, a computer will not be able to recognize a smartphone as a debugging device for transmitting system commands. Carefully follow the steps to avoid errors.

Activation of the developer mode on Xiaomi

Before you look for where Xiaomi is debugging over USB, you need to unlock the hidden menu. Manufacturers hide these settings, as carelessly changing the settings can lead to unstable system operation. First, open the standard Settings app and go to the topmost section About the phone.

Inside this section, you'll need to find a line called the MIUI Version (or the OS Version in the new firmware). You need to quickly press this line 7-10 times in a row. You don't need to do it slowly, you'll want to use a rhythmic pace. At the bottom of the screen, a pop-up counter will show you how many times you have to press.

Once you have completed the action, you will see a notification saying, “You’ve become a developer!” If the system requests a graphical key or unlock password, enter them, a security measure that ensures that the device owner is the one who accesses the hidden features.

💡

If the counter is reset, try to change the rhythm of the presses: make short series of 3-4 clicks with minimal pauses between them.

Location of the debugging menu in MIUI and HyperOS

Once the developer mode is activated, the feature is moved to a new location. In the MIUI and HyperOS shells, the path to settings is as follows: go back to the main settings menu, scroll down to the Additional Features section (sometimes called Advanced Settings), and select Developer For.

There are a lot of options on the list that opens, but we're interested in the Debugging block. This is the USB Debugging option. It's off by default. Put the slider back in active position. The system will alert you to the risks of data transfer -- confirm the action by clicking OK.

It is worth noting that depending on the version of Android, the interface may be slightly different, in some cases you need to additionally allow the installation of applications from unknown sources or confirm the action through a pop-up with a countdown timer (usually 10 seconds).

• 📱 Go to Settings. → About the phone and press 7 times on the firmware version.
• ⚙️ Open the Settings. → Additional functions → For developers.
• 🔌 Find the Debugging Point on USB And activate it with a slider.
• ✅ Confirm the security warning by pressing the OK button».

Configure permissions when connecting to a PC

Just turn on the switchboard in the settings is not enough to start.When you first connect a Xiaomi smartphone to a computer through a computer USB-cable, on the screen of the mobile device will necessarily appear a dialog box with a request to Allow debugging USB?. This window will display a unique key. SHA-1 The computer you are connecting to.

To automate the process in the future, it is recommended to check the box Always Allow from this computer, which will eliminate the need to confirm the connection every time you restart. ADB-If you plan to use the device on public PCs, this tick should not be ticked.

⚠️ Warning: Never agree to a debugging request unless you connected your phone to your computer in person.This could mean your device is trying to connect to an infected charger in a public place.

If the window doesn't show up, check the cable. Cheap cables often only support charging and don't transmit data. Also try switching USB mode in the notification curtain from Charging Only to File Transfer (MTP).

Additional debugging parameters

The developer menu hides not only basic settings, but also advanced features useful for testing. USB It allows you to emulate different types of connections, such as MTP, PTP or RNDIS (USB-This can be useful if the computer does not see the phone in standard mode.

Also worth paying attention to the item Do not turn off the screen. When debugging the screen of the smartphone can go out, breaking the connection with the PC. Activating this feature will prevent going to sleep while working with ADB. Another important setting is Wi-Fi debugging, which is available in Android 11 and above, allowing you to connect wirelessly.

For advanced users, the Debugging Service Launch feature is available, which allows you to control a device even without being tied to a particular computer using key pairs, and this is especially true for application developers.

Fastboot Mode and its Differentiation from ADB

Users often confuse the debugging of USB It's Fastboot mode. It's two different protocols. ADB It works when Android is already loaded (or in Recovery mode), and allows you to manage files and applications. Fastboot works at a lower level, before the OS boots, and is used to flash memory partitions.

To get into Fastboot mode on Xiaomi, you turn off your phone and press the Volume Down and Power buttons simultaneously. The screen will show an image of a rabbit repairing an android. In this mode, normal USB debugging does not work, special Fastboot commands are required.

Below is a table comparing the main characteristics of the two modes:

Common mistakes and ways to solve them

Even if you follow instructions correctly, there can be problems. One of the common mistakes is that the computer doesn't see the device in debugging mode. In Windows Device Manager, it can appear as "Unknown Device" or "Android" with a yellow exclamation point, which means that Xiaomi USB Driver or Google USB Driver drivers are not installed.

To solve the problem, download the official driver package from the manufacturer's website or use universal drivers. ADB. Once the drivers are installed, you need to restart the computer. USB-port: connect the phone directly to the motherboard (behind the PC), bypassing the front ports of the case.

Another problem is the developer's grey menu when items are inactive, which can occur if the device has ad ID lock enabled or specific security modules installed. Try disabling MIUI Optimization in the same developer menu (you need to click multiple times to activate), but be careful: this can change the system interface.
