How to allow debugging on USB on Xiaomi: the complete guide

Activating debugging mode is a key step for any smartphone owner who wants to gain extended control of their device.Without this parameter, it is impossible to establish a connection to a computer for deep diagnostics, installing applications outside the Play Market store or using specializedlits to modify the system. Owners of Xiaomi, Redmi and POCO often face additional layers of MIUI protection that require not only switching on the switch, but also confirming actions through a security pop-up.

The process of activating USB Debugging on devices of this company has its own nuances, which distinguish them from stock Android. Here the sequence of actions is important, since skipping even one step, for example, a countdown timer, will lead to inability to connect. Understanding how this function works will allow you to avoid many errors when you first connect to a PC.

In this article, we will take a closer look at each step, from finding hidden menus to solving driver problems, and learn not only to enable the feature, but also to manage security resolutions correctly, which is critical for a stable gadget.

Activation of the Developer Mode on MIUI

The first and mandatory step is to unlock the hidden section “Developers”; by default, this item is hidden from the eyes of the average user to prevent accidental changes in critical system parameters. You need to open the standard Settings application and go to the topmost block where information about Mi Account and system version is displayed.

Find the MIUI Version string (or the OS version on the new HyperOS shells). You need to quickly tap this element seven times in a row. You don't have to do it in a frantic rhythm, but the intervals between taps should not be too long. After the fifth or sixth time, the system will alert you that you are four steps away from turning on the mode.

If you have a digital password or a graphical key installed on your device, the system will require you to enter it to confirm your actions. Once you have successfully entered, you will see a pop-up message saying “Now you are a developer!”. This means that a new section has appeared in the settings menu, which is necessary for further manipulation.

  • 📱 Open the Settings. → The phone.
  • 👆 Quickly press 7 times on the version MIUI.
  • 🔑 Enter the screen unlock password if required.
  • ✅ Wait for notification of successful activation.

⚠️ Warning: If you accidentally turn on the developer mode, just restart the smartphone. In some versions of the shell, this action resets access, but it is more reliable to immediately turn off the switchboard in the menu that appears if you do not plan to use it.

Search and enable debugging via USB

Once you activate the hidden menu, it becomes available in the general settings of the system, and the path to it may vary slightly depending on the version of the shell, but the logic remains the same. Go back to the main settings menu and scroll down to the optional settings, and that's where the partition is hidden.

Inside the Developer Menu, you'll need to find a USB Debugging Switch, which can be at the top of the list or in a group of debugging settings, and before you switch the slider, the system will display a security risk warning, which is the standard procedure for informing developers that the mode is designed for developers.

When you first turn on, you may need to confirm through the lock screen password. After activation, an Android robot icon may appear in the status bar (notification curtain), which signals that the interface is ready for debugging.

💡

Without the enabled item “Debugging by USB”, the computer will not be able to communicate with the smartphone in ADB mode, even if the cable is serviceable.

It is important to note that on some global firmware versions, the menu item may simply be called “USB Debugging” if the language of the system is set in English.

Configure USB settings and select mode

The most common mistake of users is to ignore the choice of mode of operation USB-When you connect your phone to your computer for the first time after you debug it, it defaults to Charge Only, in which the data is locked, and the computer can't see the device, even though it's charging.

To fix this, plug in the cable and lower the notification curtain. Find the USB Charge (or similar) message and click on it. The menu will open where you want to select File Transfer (MTP), only then Windows or another OS will be able to recognize the device. In some cases, you will need to select the USB Debugging mode in the dialog window on the smartphone screen that appears.

Also worth noting is the default USB configuration item in the developer menu. If you connect your phone to your PC often, it makes sense to change this setting so that the device always offers file transfer, not just charging, which will save time in the future.

  • 🔌 Connect the cable to the PC and phone.
  • 🔽 Lower the notification curtain on your smartphone.
  • 📂 Select File Transfer Mode or Android Auto.
  • 🖥️ Check if the device appears in my computer».

If you plan to use ADB to emulate clicks or other advanced features, make sure that the developer menu also activates the option “Debug over USB (security settings).” This allows you to simulate clicks through ADB, which is necessary for some automation scripts.

Computer authorization and access confirmation

A critical step that is often overlooked: Even with the right connection and debugging enabled, the computer won't get full access until you confirm it on your smartphone screen. When you first connect a new PC, the phone's display will display a "Allow debugging over USB?" dialog box.

This window will be displayed RSA-You need to tick the "Always allow from this computer" box and click "OK." Without this command step, you need to tick the "Always allow from this computer" box. ADB They'll return the "unauthorized" error. If you don't tick, you'll have to confirm each time you connect.

What to do if the authorization window does not appear?
If the dialog box doesn't pop up, try this: 1. Turn off and reconnect the cable. 2. Make sure the screen is unlocked. 3. In the developer menu, find the item "Cancel USB debugging authorization" and press it, then reconnect the cable. This will reset the list of trusted computers and call the request again.

Sometimes the confirmation window may overlap with other applications or not appear due to interface errors, in which case it helps to clear the cache of the Google Play Services service or simply restart both devices. Make sure that the time and date on the phone and computer are synchronized, as desynchronization can block the installation of a secure connection.

⚠️ Warning: Never click “OK” in the authorization window RSA-If you don't recognize the computer you're connected to, it could give an attacker full access to your data.

Solving driver and connection problems

Often, all settings are correct, but the computer still doesn't see the phone or identifies it as an unknown device. 90% of the time, the problem is the absence or incorrect operation of ADB Interface drivers. Windows can automatically install the MTP driver for files, but the debugging driver will have to be installed manually.

To solve the problem, download the official Platform Tools package from Google or use universal drivers from Xiaomi. After installing the archive, go to Device Manager on your PC. Find a device with a yellow exclamation mark (often marked as Android or Unknown Device). Right click → Update driver → Select a driver from the list of available. From the list, select Android ADB Interface.

☑️ Diagnostics of connection

Cheap charging-only cables don't have any physical contacts to transmit data; use the original cable or high-quality cable with the stated high-speed transmission support; damage to the Type-C connector can also lead to unstable connections when contact comes and goes.

Security and resetting debugging settings

Use of debugging USB It's a great opportunity, but it's also a potential risk. When you're in a public place, don't leave your phone connected to someone else's charging station («USB-Condom") in debugging mode, as this theoretically allows you to read data from the device. Always turn off the function when you don't need it.

If you sell a phone or transfer it to another person, make sure to reset permissions. There is a button on the developer menu that says "Cancel debugging authorization by USB»**. Clicking on it removes all saved RSA-The keys of computers that your smartphone previously connected to ensure that a new owner or stranger cannot access the system without your knowledge.

💡

Before selling your phone, make sure to do a full Wipe Data reset, not just debugging, which will delete all personal data and account settings.

Also worth mentioning is the Select Debugging Application feature, which allows you to choose which application will be given priority when you run debugging commands. For the average user, you don't need to change anything, the value should remain empty or standard.

⚠️ Attention: Enable the option “Debugging by” USB (Security settings" allow applications to simulate clicks. Don't turn it on for untested programs, as malware can gain full control of the interface.

Frequently Asked Questions (FAQ)

Is it safe to keep USB debugging on all the time?
Technically, it's safe for the smartphone itself and doesn't affect battery or system wear. However, from a cybersecurity perspective, it's a risk. If you lose a phone with debugging enabled, it'll be easier for an attacker to access data, especially if they can bypass the lock screen or exploit ADB vulnerabilities.
Why does a computer see a phone as a charger?
This is because Android defaults to Charge Only mode to save energy and security, and you have to manually switch the mode in the notification curtain to File Transfer or Photo Transfer (PTP) each time you want to work with data. You can change the default behavior in the developer menu at the default USB configuration.
Do I need the internet to enable debugging over USB?
You don't need the Internet to activate the switch, but if you plan to use ADB Wirelessly, you need a network, and you may need the Internet to install drivers on your computer if they're not built in, or to authorize Mi Account when you first start some system functions.
How to turn off debugging if the phone screen is broken?
If the sensor is not working, but the image is, you can try to connect USB-mouse-wise OTG-If the screen is completely black and the touchscreen is not working, you can't softwarely disable debugging, and then you can only completely reset it through Recovery Mode, but that will delete all the data.
