The situation where the Xiaomi display is broken or no longer responsive to touch, but the smartphone itself is functioning, is one of the most stressful for the owner. Internal components can be intact, data is saved, but the lack of visual control or a working touchscreen makes the device almost useless. However, there are several proven ways to restore access to files or even fully control the gadget through the computer.
In this article, we will discuss in detail the technical aspects of connecting Mi and Redmi smartphones to the PC through the USB-You'll learn how to activate debugging mode without image, which cables are suitable for data transmission and why a conventional charging cord may not work. It is critical to understand that the success of the operation depends on 90% of whether the debugging was enabled in advance. USB developer-setting.
We'll look at both software methods that require minimal investment and options that use OTG adapters to connect the mouse. Even if the screen only shows white death or black bars, the chances of saving photos and contacts remain high with the right approach to diagnosis.
Diagnosis of the condition of the smartphone and preparation of equipment
The first step before any manipulation is to make sure that the problem is in the matrix or touchscreen, not in the system failure or battery discharge. If the phone makes a vibration sound when connected to the charger or the LED lights up, then the motherboard is alive. This is the foundation for further action.
You'll need a high-quality cable to connect to your computer. Cheap cords bundled with (power bank or cheap headphones often only support charging and don't have data lines. Use the original cable or certified USB 2.0 or higher.
It is also worth checking the condition. USB-If the connector is shattered or clogged with dust, the contact for data transmission may not be available even if charging is underway.
If you plan to use software methods, make sure that the computer has the basic ADB drivers installed. Without them, the system will not be able to recognize the phone in debugging mode, even if the physical connection is installed correctly.
Using the OTG adapter for touchscreen-free control
The easiest and most effective way to access data if the image on the screen is at least partially visible, but the touchscreen does not work is to use an adapter. OTG (This little adapter lets you plug in a regular computer. USB-mouse-to-smartphone charging connector.
Once you connect your mouse through the OTG, a cursor will appear on the screen (if it shows a picture), which allows you to unlock the device, enter a pattern lock or pin code, and copy important files to your computer or the cloud.
However, if the screen is completely black, this method requires blind input. You need to remember the approximate location of the icons. Connect the mouse, wait for the connection sound, then press the left mouse button in the center of the screen (unlock) and try to grope the notification area with the cursor.
💡
Use a wired one. USB-mouse, as wireless may not have enough power from the smartphone, and it simply will not be determined by the system.
Some Xiaomi models require confirmation of connection USB-If the screen is black, you can't press "OK." Then try plugging in. OTG-Hub with keyboard and mouse at the same time to try to use hot keys.
Activate debugging over USB without visible image
For advanced PC management, it is critical that the USB Debugging feature be activated in the developer menu, and if you don't turn it on in advance, the standard ADB methods won't work.
Some versions of the MIUI or HyperOS shell require a confirmation on the smartphone screen when you connect to a new computer ("Always allow debugging from this computer?") If the screen is black, you can't confirm that. But if you've previously connected this PC and ticked "Always allow" the access will open automatically.
To check if debugging is active, you can try sending a command through the console, and if the phone responds with a list of devices, it means that access is available, and if you see the status of unauthorized, then you need a confirmation on the screen that you can't give.
How do you turn on blind debugging?
If debugging wasn’t enabled, your options are narrowed to using cloud services or recovery mode if it supports MTP. In modern versions of Android, security is enhanced, and you can’t simply access the file system without a screen confirmation.
Connecting via ADB and Windows Command Prompt
If debugging is activated, you can control your phone through ADB (Android Debug Bridge), a powerful tool that is part of the Android SDK Platform Tools, which allows you to transfer files, take screenshots, and even broadcast the screen.
To get started, download the archive with platform tools from the official Google website, unpack it and open the command line in the platform-tools folder. Connect your smartphone with a cable to your PC.
Enter a command to check the connection:
adb devicesIf a device with a serial number and device status appears on the list, the link is established. If the offline status or list is empty, check the drivers in Windows Device Manager.
☑️ Connection check ADB
With help. ADB You can copy all the photos and videos with one command without seeing the screen. /sdcard/DCIM/ C:/Backup_Mi/ to save the camera folder to the computer.
Screen broadcasting and control via Scrcpy
One of the best solutions for a broken screen situation is Scrcpy, which allows you to display an Android image on your computer screen and control your smartphone with a mouse and keyboard with minimal latency.
The main advantage of Scrcpy is that it does not require installing apps on the phone itself and works immediately after launch on the PC, if you allow debugging over USB. This is ideal when the touchscreen does not work at all, and the image needs to be seen clearly.
Run the executable scrcpy.exe. If the connection is successful, a window will appear on the monitor with the interface of your Xiaomi, you can unlock the phone, open the gallery, messengers and transfer data.
| Parameter | Description | Meaning for Scrcpy |
|---|---|---|
| Bitreit | Image quality | 8 Mbps (by default) |
| Delay. | Response time (latency) | 35-70 ms. |
| Frequency of personnel | Smoothness of the interface | Up to 120 FPS. |
| Installation | Telephone requirements | Not required |
To improve the quality of the picture, you can use the command:
scrcpy --bit-rate 16M --max-size 1920This will set the bitrate to 16 Mbps and limit the resolution of the Long-side to 1920 pixels, which will reduce the load on the PC processor.
Use of cloud services and Mi Cloud
If the software methods through USB don't work because of the lack of debugging, there's hope for cloud services. Xiaomi smartphones have a deep integrated Mi Cloud. If you were signed into Mi Account, the data could sync automatically.
Go to i.mi.com from your computer and log in to your account, where you can find contacts, notes, calendars and possibly photos, and check out Google Photos, which is often the default service for backing up media.
⚠️ Note: Accessing Mi Cloud via the web interface may require a confirmation code that will come via the SMS. Make sure that SIM-The card in the phone is active and receives the signal, otherwise you will not be able to log in to the account.
You can also check Google's Find My Device service, which is not a way to download files, but you can try to unlock the screen or display a message that will block the interface if the phone suddenly starts showing a picture.
Alternative programs: Mi PC Suite and TeamViewer
The official Mi PC Suite program was once the main tool, but it now works poorly with new models and versions of Android. However, for older devices (released before 2018), it can be a salvation, allowing you to do backups without debugging (via account).
If you have TeamViewer QuickSupport or AnyDesk installed on your phone and granted access rights, you can remotely connect to your device from your PC, but you can't do that without setting up.
💡
Without pre-enabled USB debugging or a remote access application installed, software-based access to the new Android file system is virtually impossible for security reasons.
If the software methods fail completely, the only option left is to temporarily replace the display in the service center to extract data, which is a fee, but guarantees the result if the motherboard is intact.
