Owners of Xiaomi and Redmi smartphones often face the need to obtain advanced access rights to the system to install specialized software, firmware or deep memory cleaning. The standard interface of the Android operating system hides these functions from the eyes of the average user, requiring certain actions to activate them, a process that is not complex, but requires care, as it affects the system settings of security.
Activating debugging mode opens up access to the ADB (Android Debug Bridge) protocol, which is the bridge between your computer and your mobile device, which allows you to send commands, install applications to bypass standard constraints, and even restore your system after critical failures. Without enabling this feature, many customization and repair tools will not see your phone.
In this article, we will take a detailed look at each step required to unlock a hidden developer menu, learn how to properly configure a connection, what drivers might be required, and what to do if a computer stops responding to connections. Understanding these processes will help you avoid typical errors and safely manage your gadget.
Why you need a debugging mode on Android
USB debugging mode is a diagnostic tool originally designed for application developers, which allows them to test programs on a real device, track code errors and analyze system performance in real time, but in the hands of advanced users, this tool is becoming a powerful smartphone control mechanism.
With activated ADB, you can perform operations that are not available through the standard settings menu, such as removing system applications (bloatware) that the manufacturer does not allow you to remove in the usual way, or creating full backups before flashing, and this mode is critical for unlocking the bootloader, which is the first step to install custom firmware.
⚠️ Warning: Enabling debugging mode makes the device visible to any connected computers.Do not activate this feature on public charging stations or unknown PCs to avoid potential data theft.
In addition, through debugging, you can force older versions of apps to be installed, change screen resolution, and even emulate GPS location to test services, giving you full control over your Redmi hardware and software.
Preparing the device and computer for connection
Before you go to menu settings, you need to make sure the equipment is ready to go. USB-Cheap cables that come with some accessories often only support charging and don't have data lines. Use the original cable or certified analogue with data support.
The computer must have the appropriate drivers installed. In Windows 10 and Windows 11 operating systems, drivers are often installed automatically on the first connection, but for ADB to work smoothly, it is better to download Google USB Driver or use the universal Xiaomi driver. For users of macOS and Linux, additional drivers are usually not required, but you may need to configure access rights.
☑️ Checking debugging readiness
It is also recommended to back up important data. While the debugging process itself is safe, any manipulation of system settings carries a minimal risk of failure. Make sure that the smartphone is enabled by default file transfer, not just charging.
Activation of the Developer Menu on MIUI
In the MIUI shell, which is installed on all Xiaomi and Redmi smartphones, the developer menu is hidden by default. To activate it, you need to perform a series of quick taps on a special field in the settings, which is a standard measure of protection against accidental changes in critical system parameters.
Open the Settings app and scroll to the bottom of the list. Find About Phone (or Device). Inside this section, you are interested in the MIUI version. You need to quickly click on it 7-10 times in a row. After a few clicks, a countdown pop-up message will appear ("Push 4 times left"), and then a notification: "You became a developer."
If the lock screen password is not set, the system may ask you to specify a pin or pattern lock before activating the mode. This is a mandatory security requirement for Android. Once the actions are successfully completed, the new menu will appear in the main settings list, usually immediately below the “Additional” item or at the very bottom of the list.
💡
If nothing happens after 10 taps, check whether Do Not Disturb or Second Space is enabled, as these can block system notifications about changing user status.
In some versions of firmware for CIS countries or global versions, the path may differ slightly. Sometimes you need to go to the "Advanced Settings", where the item for developers hides after it is activated, the main thing is not to give up after the first attempts, the rhythm of the pressing should be fast, but not chaotic.
Set-up of parameters USB-debugging and confirmation
Once you have the "Developer" option in your settings, go to it. The settings list is going to be impressive, but we're only interested in one, "Debugging USB." Put the slider back to active position. The system will immediately issue a warning about the risks associated with using this feature. Press "OK" to confirm.
Now connect your smartphone to your computer through USB-For the first time, when you connect to a new computer, you'll see a dialog box on your phone asking for debugging permission. RSA-You must check the box "Always allow debugging from this computer" and click "Allow».
⚠️ Warning: If you don't check the "Always Allow" box, every time you reconnect the cable or reboot the phone, you'll have to reconfirm access, which can be annoying when you're using the device frequently.
It is important to note that in the new versions MIUI There's an extra protection on the debugging menu. USB There is a sub-item "Installation through USB» (Install via USB). For some tools (such as Mi Unlock or Mi Flash), this option must also be enabled. SIM-Card and authorization in the Mi Account.
Typical Connection Problems and Their Solutions
Even with all the steps done correctly, users can encounter situations where the computer can't see the device or refuses to follow commands. One of the most common reasons is the wrong USB mode. By default, the phone can go into Charge Only mode. To fix this, lower the notification curtain after connecting the cable, click on the "Charge via USB" notification, and select File Transfer (MTP) mode.
Another common problem is the lack of ADB drivers on the system. If the Windows Device Manager displays a device as “Unknown Device” or with a yellow exclamation mark, you need to update the driver manually. Select “Update Driver” → “Select from the list of available drivers” → “MTP USB Device” or “Android ADB Interface”.
Sometimes antivirus software or firewall can block the ADB connection, considering it suspicious activity, in which case it is necessary to temporarily disable the protection or add an exception to the adb.exe process. Also make sure that the phone has enabled the function “Debug over USB (Security settings)” if this option is present in your version of the firmware.
Use ADB and Basic Instructions for Verification
To make sure that the debugging works correctly, you need to check the connection through the command line. Open the folder where the Platform Tools (ADB) is installed, press Shift and click the right mouse button by selecting "Open PowerShell window here" or "Open Command Prompt." Enter the command to check the list of connected devices.
adb devicesIf you're configured correctly, the terminal window will display a list of connected devices with their serial numbers and device status. If you see unauthorized instead, look at the phone screen -- there should be a confirmation request. RSA-Offline status usually indicates problems with drivers or cable.
| Team team. | Description of action | Outcome of implementation |
|---|---|---|
| adb devices | Connection check | List of serial numbers of devices |
| adb reboot | Rebooting the smartphone | The device goes into reboot. |
| adb reboot bootloader | Entrance to Fastboot | Screen with a hare and the inscription Fastboot |
| adb pull /sdcard/file.txt | Copying a file from a phone | The file appears in the ADB folder on the PC |
Using these commands, you can not only diagnose the connection, but also perform basic control operations. For example, the adb reboot bootloader command will put the phone into Fastboot mode, which is necessary to unlock the bootloader or firmware through the computer, which confirms that the communication channel between the PC and the smartphone is fully functional.
What if ADB sees the device but doesn’t transmit commands?
Security and completion of debugging
After performing all the necessary manipulations (install applications, uninstall logs, firmware), it is recommended to turn off debugging mode.This minimizes security risks, especially if you plan to transfer the phone to someone else or use it in public places with access to charging stations.
To turn off, just go back to the Developer menu and turn the USB Debug switch to off. You can also completely hide the developer menu if you no longer need it. To do this, there is an On switch at the top of the same menu, which removes the entire partition from the phone's settings.
⚠️ Warning: Do not leave debugging mode on permanently unless you use it regularly, which reduces the overall level of security of the operating system from potential attacks through the use of the system. USB-port.
Remember, access to ADB gives you full rights to read and write data in your phone's memory. Anyone who connects to your device with debugging enabled can copy photos, contacts or passwords stored in your browser, so controlling this mode is a matter of digital hygiene.
💡
USB debugging mode is a powerful tool that should only be enabled for the duration of specific tasks and disabled immediately after they are completed.
