Activating debugging mode is a fundamental step for anyone who wants to gain extended control of their Xiaomi device.This feature opens up access to the Android Debug Bridge protocol, allowing the computer to interact with the smartphone operating system at a deep level. Without enabling this option, it is impossible to install custom recavators, make a full system backup or remove system applications.
Many newcomers get lost in the maze of the MIUI menu, as Xiaomi developers have hidden the necessary switches deep in the system settings. This is done for security reasons, to prevent inexperienced users from accidentally changing critical parameters. However, with a precise algorithm of actions, you can activate the desired mode in just one minute.
In this guide, we will take a closer look at the debugging activation process, look at the nuances of working with drivers, and answer frequent questions, learn how to circumvent potential connection problems and what tools are really needed to work effectively with ADB.
Why do you need USB debugging and what is ADB?
ADB (Android Debug Bridge) is a universal command-line tool that allows your computer to interact with an Android device. It performs three basic functions: managing a device from a PC, transferring files, and emulating a terminal to execute commands. For developers, this is the main way to test applications, and for enthusiasts, it is the key to modifying the system.
Using debugging allows you to perform actions that are not available in the standard interface, for example, you can take screenshots straight into the PC clipboard, install apps bypassing Google Play, or even control the phone while its screen is broken, a powerful tool that requires careful handling.
⚠️ Warning: Enabling debugging mode makes your device visible to any connected computers.Never connect your smartphone to public charging stations or someone else's PC with activated debugging, as this can lead to data theft.
It’s important to understand the difference between just enabling debugging and having root rights. USB debugging doesn’t give you full access to the file system, it just opens the door for debugging commands. It requires additional actions to gain superuser rights, often starting with ADB.
💡
Use only original or certified USB cables for debugging. Cheap charging-only cables have no data lines, leading to endless attempts to connect without result.
Activate the Developer Menu on MIUI
The first and mandatory step is to unlock the hidden settings section, and the MIUI shell has the default hidden menu, and to activate it, you'll need to do a series of quick taps on a specific system identifier.
The activation process is as follows:
- 📱 Open the Settings app on your smartphone.
- 🔍 Go to the top of the menu – About the phone.
- 👆 Find the line Version MIUI And press it fast. 7-10 successively.
- ✅ Wait for the notification “You became a developer!".
Once these steps are completed, a new section will appear in the main settings menu, and its location may vary depending on the Android operating system version and the MIUI shell. It is usually in the “Additional” or “Extended Settings” section.
☑️ Checking the activation of the menu
Enabling debugging over USB in settings
Once the hidden menu is available, you need to activate the debugging function itself. Be careful, there are many parameters in this section that can affect the stability of the system.
Algorithm of actions to include:
- ⚙️ Go to Settings. → Additionally. → For developers.
- 🔌 Find the debugging switch by USB and activate it.
- ⚠️ Confirm the action in the pop-up window by agreeing to the warning.
- 🔒 If the device requests a password or pattern lock, enter it to confirm it.
From now on, your Xiaomi smartphone is ready to connect to your computer, but when you first connect to a new PC, you'll see a request for debugging permission from that computer on your phone's screen, and you'll check "Always allow from this computer" and click OK.
In some cases, especially on newer versions of MIUI 13/14, the system may require additional authorization through a Mi Account or the input of a confirmation code sent via SMS.
Why is there no request for permission?
Configure additional debugging parameters
To be able to work with tools like Mi Unlock or Mi Flash Tool, basic settings may not be enough, and you often need to activate additional options that regulate behavior. USB-interface.
Pay attention to the following parameters in the developer menu:
- 🛠 Debugging by USB (security settings: allows you to install applications from ADB without screen confirmation (requires reconnection).
- 🔓 Factory Unlocking: Required only to unlock the bootloader (Bootloader).
- 📡 Choosing a configuration USB: Make sure you have a file transfer mode, not just charging.
Particular attention should be paid to the functions USB-Debugging (security settings) If you plan to use tools to remove system debris or freeze applications (for example, through ADB AppControl, this option needs to be enabled, without which the computer will not be able to execute commands to install or uninstall the software.
| Parameter | Default status | Recommended value | What do you need? |
|---|---|---|---|
| USB debugging | Off. | Included. | ADB Basic Connection |
| Safe debugging | Off. | Included (by requirement) | Installation of applications without confirmation |
| Factory unlocking | Off. | Included (for BL) | Unlocking the loader |
| USB configuration | Charging. | File transfer | Stable data exchange |
Installation of drivers and work with ADB on PC
Even if the phone is all-on, the computer may not see the device correctly. Windows often doesn't have built-in drivers for Xiaomi's debugging mode. In Device Manager, this can appear as "Unknown Device" or "Android" with a yellow exclamation mark.
To solve this problem, follow the following steps:
- Download the official Minimal ADB and Fastboot package or drivers from the developer’s website.
- Connect your phone to your PC with a cable.
- Open the Device Manager, find an unknown device, right-click and select "Update driver".
- Select "Select a driver from the list of available drivers on your computer" and specify the path to the downloaded files.
After successful driver installation, the connection is checked via the command line. Open the terminal (cmd) in the folder with ADB tools and enter the command:
adb devicesIf the serial number of your device with device status is displayed on the list, then the connection is successfully established. RSA-key.
💡
A successful command "adb devices" with display of serial number is the main indicator that debugging over USB works correctly and drivers are installed correctly.
Solving Typical Connection Problems and Errors
During the setup process, users often encounter a situation where the switch on the menu is on, but the computer only reacts by charging, which can be caused by cable damage, a port malfunction, or software conflict.
The main causes of failures:
- ❌ Charge Only mode: Check the notification curtain when connecting and change mode to File Transfer".
- 🚫 Antivirus Blocking: Some Security Programs Block Debugging Connections.
- 📱 Unstable assembly MIUI: On beta versions of firmware, the function may not work correctly.
If nothing helps, try to turn off all the extras. USB-It's also a way to clean up the list of authorized computers in the developer menu ("Cancel Access" button) and re-pair.
⚠️ Note: Do not try to install drivers from other manufacturers (Samsung, Huawei) for Xiaomi. This can lead to a conflict of system libraries and the inability to connect any Android devices before reinstalling Windows OS.
