Activating debugging mode on Xiaomi, Redmi and POCO devices is a fundamental step for users who want to gain increased control over their gadget.This feature gives access to the Android Debug Bridge protocol, which is necessary for deep configuration, customization recavators or unlocking the bootloader. Without these actions, many advanced manipulations with the MIUI or HyperOS operating system are simply impossible.
The activation process is hidden in the developer menu, which is closed by default from the eyes of the average user, and is done for security reasons to prevent accidental changes in critical system parameters. However, knowing the correct sequence of actions, you can quickly unlock the desired functionality and start working with the right system. ADB-commands or specialized utilities for PC.
In this article, we will discuss each step in detail, from turning on the developer menu to checking the connection to the computer. You will learn about the nuances of working with drivers, the features of connecting on different versions of firmware and methods for solving typical errors. To unlock the Xiaomi bootloader, you need an active Internet connection and an account binding Mi Account, while for the first time, you need to use the Xiaomi bootloader. ADB-Debugging isn't always necessary.
Why do you need USB debugging and what opportunities it gives
The debugging feature is primarily designed for application developers who test their programs on real devices, but the average user can also benefit from it. ADB (Android Debug Bridge) can remove system applications that cannot be removed by standard methods, make full data backups or install modified versions of the operating system.
In addition, this mode is indispensable for the recovery of broken smartphones. If the device is in a reboot cycle or does not turn on correctly, connecting through debugging is often the only way to bring the gadget back to life without going to the service center.
The list of main tasks solved through this interface includes:
- 📱 Unlocking the bootloader (Bootloader) for installing custom firmware.
- 🗑️ Removal of system debris and pre-installed advertising without root rights.
- 💻 Control of the smartphone from the computer: file transfer, screenshots, text input.
- 🛠️ Installation of drivers and debugging applications in real time.
⚠️ Warning: Enabling debugging mode reduces the security of the device.Do not connect your smartphone to other people's or public computers in this mode, as an attacker can gain full access to your data.
Activation of the developer menu on different versions of MIUI and HyperOS
The first step to activating debugging is to open a hidden settings section. In the shells of MIUI 12, 13, 14 and the new HyperOS, the procedure is almost identical, but has its own nuances in the location of the points, you need to find information about the version of the system and make a series of quick presses.
Go to your phone and select About Phone. Find the MIUI Version (or OS Version) line. You need to quickly click on this line 7-10 times in a row. Once you do it correctly, a pop-up notification will appear "You've become a developer!". Now a new section will appear in the main settings menu.
If there is no notification, check if you have Advanced Settings enabled at the top of the About Phone menu. In some regions, the developer menu item may be called Additional. After a new section appears, go to Settings → Additional Settings → Developer.
Step-by-step instruction for debugging and PC authorization
Once you log into the developer menu, find the USB Debugging Switch. Activate it. The system will alert you to potential risks — confirm the action. Now your smartphone is ready to connect, but you will need authorization to work with a particular computer.
Connect your phone to your PC with high-quality USB-A dialog box will appear on the smartphone screen asking, "Allow debugging by USB?» display RSA-Make sure to check the box "Always allow from this computer" and press OK. Without this step, the connection will not be established.
☑️ Connection check
It is important to make sure that the USB settings menu (usually called down swipe with the cable connected) selects File Transfer (MTP) or PTP. In Charge Only mode, debugging will not work even if the switch in the menu is activated. Also, the developer menu should check the "Default USB Configuration" item.
Installation of drivers and check connection via ADB
For a computer to see a smartphone in debugging mode, drivers are needed. On Windows 10 and 11, they are often installed automatically, but for stable operation, it is better to use the official Platform Tools package from Google, a set of utilities that includes adb.exe and fastboot.exe.
After downloading the archive from the Android Developers platform, unpack it to the root of the disk (for example, in the folder C:\platform-tools). Open the command prompt (CMD) or PowerShell in this folder and enter the verification command:
adb devicesIf you're set up correctly, you'll see the serial number of your device that's status-device, and if you see that status-unauthorized, look at the phone screen, and there's a confirmation request. RSA-Offline status usually indicates a driver or cable problem.
| Status at ADB | Meaning | Action. |
|---|---|---|
| device | The device is connected and ready to go. | You can run commands. |
| unauthorized | Requires confirmation on the phone screen | Click "Allow" on the smartphone screen |
| offline | Communication is in place, but the device is not responding. | Reconnect the cable, check the drivers |
| no-devices | The computer can't see the phone. | Replace the cable, check the USB mode |
Configure additional debugging parameters
There are a lot of useful settings that you can use in the developer menu when debugging, like Wi-Fi debugging, which allows you to connect your device wirelessly, which is convenient for testing the interface, and you need to have your phone and your PC on the same network to work.
Also worth paying attention to is the "Select a debugging application," where you can select a specific program that will be subject to special logging modes, which helps developers track errors in the code without creating too much noise in the system logs.
What is USB Debugging (Security Settings)?
Don't forget to set the default USB configuration setting, so you don't have to manually change the mode in the notification curtain every time you connect, and that saves you time and avoids unnecessary action.
Solving Connection Problems and Errors
A common problem on Xiaomi devices is the lack of response to despite debugging. 90% of the time it's the cable. Cheap charging-only cables don't have data lines. Use the original wire or certified counterpart labeled A-to-C or C-to-C depending on the PC port.
If drivers don’t install, try manually updating them through Device Manager in Windows. Find an unknown device (often marked with a yellow exclamation mark), select Update Driver → Select from the list of available drivers → Android ADB Interface.
⚠️ Warning: When connecting to a new computer, always check RSA-A blind click on OK on an unfamiliar PC can lead to data theft or malware installation.
In some cases, resetting the debugging settings helps, so in the developer menu, find the Revoke Debugging Permissions button on USB and press it, then reconnect the cable and confirm the authorization request, which clears the list of trusted computers.
Security and completion of debugging
After performing all the necessary manipulations (firmware, application removal, backup), it is recommended to turn off debugging mode.This minimizes security risks. ADB-scripts or automation tools.
Remember that while debugging is enabled, anyone who gets physical access to your unlocked phone will be able to copy any data from it via the device. USB-cable bypassing screen lock (unless additional protections are installed) so do not leave your phone unattended in public areas with active developer mode.
💡
For quick debugging activation, add the USB Debugging switch to the notification curtain via the Quick Settings editing menu.
In conclusion, the proper use of debugging tools makes your Xiaomi a powerful tool with almost limitless customization options, the main thing is to be careful and understand the meaning of the commands you enter.
💡
USB debugging is the key to full control of Android, but it requires responsibility: always turn it off after use and don’t connect your phone to someone else’s PC.
