Today’s Xiaomi, Redmi, and POCO smartphones are complex computing devices that sometimes require deeper interaction with the system than just installing apps from a store. Enabling USB debugging mode becomes a critical step for developers, custom firmware enthusiasts, or users who are faced with the need to remotely control the device through a computer. Without activating this hidden interface, many advanced tools simply will not be able to “see” your phone.
The activation procedure is not complicated, but it requires care, as it is hidden in a specially designated engineering menu, access to which is limited to avoid accidental changes by inexperienced users.Enabled debugging by USB opens the gateway for transferring ADB commands, which allows you to install applications directly, make full system backups or even unlock the bootloader if necessary for flashing.
In this article, we will take a detailed look at each step required to activate the feature on current versions of the HyperOS and MIUI shell. You will learn not only about the standard activation path, but also about the nuances that can be encountered on different models, as well as about the security measures that must be followed when working with system settings.
Why USB Debugging is Necessary and What Risks It Receives
The debugging feature was originally created by Google engineers to test applications during development, but over time, it has become indispensable for a wide range of tasks, allowing you to transfer files between your computer and phone in real time, install system drivers, or even control the screen of your smartphone from your PC. For many users, this is the only way to restore access to data if the touch screen stopped responding, but the image remains.
However, when you open this port, you need to be aware of the potential threats. Connecting your smartphone to someone else's computer or public charging station with activated debugging can theoretically allow attackers to access your data or install malware without your knowledge. That's why Android requires confirmation of connection every time you first connect a device to a new PC.
⚠️ Warning: Never leave debugging mode on permanently unless you're using it right now. USB-Ports at airports or cafes with active debugging make the device vulnerable to “Juice Jacking” attacks».
In addition, the wrong actions through ADB-commands can lead to the removal of critical system applications, which will make the phone inoperable or require complete firmware, and understanding what you are doing is key to the security of your data. If you just want to copy photos, you just need a normal file transfer mode (MTP), You don’t need to go to the engineering menu.
Preparation of the device and computer before activation
Before you go to menu settings, make sure your hardware is ready to interact. Often, connection problems are not caused by software locks, but by a banal lack of drivers or using poor-quality cable. The computer must have Android ADB Interface basic drivers installed, which are usually loaded automatically on modern Windows 10/11 or macOS.
Pay special attention to cable. Cheap charging-only cables don't have internal contacts to transmit data, so the phone will only charge, but the computer won't see it. Use the original cable from the kit or a certified high-speed analogue. Also make sure the USB port on the computer is good and has no backlashes.
If you plan to use your phone for development or frequent connection, it makes sense to install Google’s SDK Platform Tools on your computer in advance, ensuring that all the necessary command-line utilities are available. For regular users who just need to allow apps to be installed out of the store or make a backup, standard system drivers will suffice.
☑️ Connection readiness
It is important to check the operating system version. On older versions of Android (below 4.2), the developer menu was available immediately, but in modern HyperOS and MIUI, the procedure is hidden. It is also worth unlocking the phone screen before connecting, since some models ignore debugging requests if the device is in sleep mode.
Step-by-step: how to activate the developer menu
The first and most important step is unlocking the hidden settings section. By default, the developer menu login button is hidden from the user's eyes to prevent the system from accidentally changing critical parameters. To access it, you need to perform a certain sequence of actions that is the same for the vast majority of Xiaomi smartphones.
Open the Settings app and scroll down to the bottom of the list to About Phone. Here you are interested in the "Version" line. MIUI» or "Version" OS». You need to press this line quickly. 7-10 You don't have to click in a frantic rhythm, you don't have to click in a pretty confident, rhythmic way, and the system starts counting down the remaining clicks, and it's going to pop up with notifications.
Once the limit is reached, you will see a message saying, “You’re a developer!”. Now, in the main settings menu, in the “Additional” (or “Extended Settings”) section, a new item will appear, “Developers”, and this is where all the tools for deep customization of the system, including our target function, are concentrated.
💡
If nothing happens after 10 taps, check if Child Protection or Guest Mode is enabled, which can block changing system settings.
It’s worth noting that some global firmware versions may have slightly different paths, such as pure Android on Xiaomi (the Android One series), where the item is in the System section. Either way, look for a phrase that contains the word “Build” or “Build version.”
Enabling debugging over USB and access confirmation
Once you log into the Developer menu, you'll need to find the USB Debugging Switch, which is usually located at the top of the list or in the network and connection section. Activate the switch, and the system will immediately issue a warning that this mode is designed to be developed and can be used to copy data without your knowledge.
Confirm the action by pressing OK. Now, when you connect the phone to your computer through USB-cable, on the screen of the smartphone will appear a dialog box with the question “Allow debugging on the phone” USB?». A digital key will be displayed in this window (RSA-The key is the computer you're connecting to. This is a critical security issue.
You can choose to "Always allow from this computer" if you trust this PC and plan to work with it all the time. If you connect to someone else's or a public computer, it's better to confirm the connection manually each time and not check the permanent access box. Once confirmed in the status bar, an Android icon will appear that says "Debug".
⚠️ Warning: If the confirmation request dialog box doesn’t appear, try switching mode. USB-Pull the notification curtain, click on Charge through USB» and select the "File Transfer" mode (MTP)» or «PTP», Then reconnect the cable.
Sometimes it happens that the computer sees the phone only as a charger, so in the developer menu, find the item "Default USB Configuration" and force the value "File Transfer", which often solves the problem of invisibility of the device in the Windows Task Manager.
Configure additional debugging parameters
Standard debugging may not be enough for some specific tasks. The developer menu contains many options that advanced users may need, such as Wi-Fi debugging, which allows you to connect to your phone wirelessly, which is convenient for wirelessly transferring large amounts of data or testing applications.
Also worth paying attention to is the item “Selecting a debugging application.” If you are a developer, you can choose a specific application that will run when you connect the debugger. For ordinary users, the option “Do not turn off the screen when charging” may be of interest, which is automatically activated when you turn on debugging over USB, which is convenient for long-term operations.
An important parameter is “Background Process Limit,” where you can limit the number of simultaneous applications that sometimes help with performance testing or freeing up RAM, but for everyday use, you’d better leave the “Standard Limit” value.
| Parameter | Description | Recommended value |
|---|---|---|
| USB debugging | Allows data exchange from PC | On (only when necessary) |
| Wi-Fi debugging | ADB Wireless Connection | Off (saving battery) |
| Stay awake | The screen does not go out when charging | At the discretion of the user |
| Touch demonstration | Showing pressing points on the screen | Off (for screencasts) |
You don't have to experiment with animation or window scale settings if you don't understand the impact of those on the interface, but you can reset the developer settings at the bottom of the menu by clicking Reset, which will return all hidden settings to factory values, but it won't delete your personal data.
Solution: Computer can't see phone
One of the most common problems is when all settings are on, the cable is good, but the computer still doesn't recognize the debugging device. First of all, check the Device Manager in Windows. If there's a device with a yellow exclamation mark or an Android device with an unknown ID, then the driver is the problem.
Try manually updating the driver by pointing the path to the Google Driver folder USB Driver also helps remove the device from the dispatcher and reconnect the cable, sometimes the conflict arises from third-party antivirus programs or firewalls that block the device. ADB-Try to temporarily disable the defense.
The secret method of resetting USB settings
If you use Linux (Ubuntu, Fedora), you may need to create an udev rule file to allow the system to access the device without superuser rights.In macOS, problems are less common, but sometimes you need to install additional drivers for older phone models.
In case nothing helps, try to turn on the flight mode on the phone, then turn it off again.This will restart all network modules and can eliminate the software glitch blocking the connection.
