The situation when a costly Xiaomi smartphone falls and its display turns into a chaos of cracks is familiar to many. If the touch scanner has stopped responding to touch or the matrix has completely gone out, access to important information, contacts and photos may seem impossible. However, it is too early to panic: the Android ecosystem and specific MIUI tools offer several ways to solve this problem.
Before you start to act, you need to assess the nature of the damage. If the phone turns on, vibrates when you call or makes notification sounds, then the main board is fine, and the task is to bypass the broken interface. In the case where the device does not show signs of life, the methods will be radically different and require deeper intervention in the hardware.
In this article, we will look at proven action algorithms that will help you regain access to your device memory without having to completely replace the display. We will examine both software methods through cloud services and the physical ways to connect peripherals that are relevant for most Redmi and Poco models.
Using a USB-OTG adapter and mouse
The most efficient and quickest way to access files when a broken but running touch scanner is using USB On-The-Go technology. Most modern Xiaomi smartphones support this feature by allowing external input devices such as a computer mouse to connect to a USB Type-C or Micro-USB port.
To implement this method, you will need a special adapter adapter. USB-OTG, And you can buy it from any electronics store, and when you plug your mouse into the smartphone charging connector, you'll have a cursor on your screen, if it's a little light, and you'll unlock the device, you'll enter a pattern lock, or you'll have a cursor on your screen. PIN-code and copy the data.
- 🖱️ Connect the adapter. OTG to the smartphone and wait for the cursor to appear on the screen.
- 🔓 Unlock the device by dragging the mouse cursor to the points or entering numbers.
- ☁️ Open the Google Photos or Mi Cloud app and start syncing.
- 📂 Move important files to cloud storage or to a connected flash drive.
If the screen is completely black, but the phone is making sounds, use the blind typing method, and if you know the approximate location of the icons, you can try to click on the desired area, and this method is ideal for backing up through Mi Mover or standard system tools.
☑️ Compatibility check OTG
Recovery via Mi Cloud and Google Account
If you’ve taken care of sync settings beforehand, file extraction may not require a physical connection to your phone. Xiaomi’s ecosystem is deeply integrated with cloud services, allowing you to save contacts, messages, notes, and even voice recorder files remotely.
To access data, go to the official i.mi.com website from any computer or other smartphone, you will need to log in to the same Mi Account that was used on the broken device, and it stores backups that the system created automatically when you connect to Wi-Fi.
The same is true for Google services: If your phone has been synced, your contacts and calendar are available at contacts.google.com. Photos and videos are most often saved in Google Photos, which you can log in via your browser using your Gmail account.
⚠️ Warning: Automatic synchronization only works if the phone is connected to a Wi-Fi network and has sufficient battery power. If these conditions were not met before the breakdown, the fresh data may not have time to load into the cloud.
WhatsApp, Viber and Telegram store their correspondence and media history either on their servers (like Telegram) or in local copies, which can also be duplicated in Google Drive.
What if two-factor authentication requires confirmation on a broken phone?
Connection to PC and debugging mode via USB
Connecting a broken smartphone to a computer via a USB cable is a classic method, but it has a serious limitation: By default, modern versions of MIUI connect in Charge Only mode. To see the file system, you need to select MTP mode on the phone screen.
If you can't see anything on the broken screen and you can't click "Allow" on debugging or changing USB mode, the standard connection won't work. However, if the USB Debugging menu was activated earlier and the computer was already authorized, you can use software tools.
One of these is Android Debug Bridge (ADB), a console program that allows you to control your device from a computer, and you can try to make a full backup or copy specific folders even if the screen is not working, provided that the debugging was enabled in advance.
adb pull /sdcard/DCIM/Camera/ C:/Backup/Photos/This command will copy all photos from the standard camera folder to the computer hard drive in the folder C:/Backup/Photos/. To work with ADB, you need to install Xiaomi USB Driver drivers and the SDK Platform-Tools platform on your PC.
Use of external displays and projection
Owners of Xiaomi flagship models, such as the Mi series or the top-end Redmi Note, can have video output support via a USB-C port. If your device supports the DisplayPort Alt Mode standard, you can display the image from your phone to a monitor or TV.
This requires a USB-C to HDMI adapter. If you plug your phone into a large screen, you'll see a full copy of the smartphone interface, which allows you to comfortably manage files even if the phone's matrix is completely broken, but it's worth remembering that without a mouse connection (via a USB hub), you can't control the phone.
If video output is not supported, some users resort to remote access applications such as TeamViewer QuickSupport or AirDroid. But their initial setup usually requires at least one run and permission confirmation on the phone itself, which is problematic if the screen is broken.
- 📺 Check the specification of your model on the Xiaomi website for video output support.
- 🔌 Use a quality adapter USB-C on HDMI supportive OTG.
- 🖥️ Connect your phone to your monitor and use your mouse to navigate.
- 💾 Copy data to an external drive or to the cloud via the browser.
This method is the most convenient for extracting large amounts of data, as it allows you to see everything that happens on the screen in full resolution and color, which is critical for sorting photos and documents.
💡
If you don't. HDMI-monitor, try using the smart monitor TV If you've previously paired your phone with your TV over Wi-Fi, it can automatically connect when you turn on, and you'll see the image on the big screen.
Comparison of data recovery methods
The choice of the specific method depends on the condition of your device and the availability of the necessary tools at hand. Below is a table that will help you quickly navigate the available options and their effectiveness for various breakdown scenarios.
| Method | Equipment required | It works on a black screen. | Difficulty |
|---|---|---|---|
| USB-OTG + Mouse | OTG adapter, mouse | Partially (to the touch) | Low. |
| Mi Cloud / Google | PC or other smartphone | Yes (remotely) | Low. |
| ADB Commands | PC, cable, drivers | Yes (if debugging is on) | Tall. |
| USB-C on HDMI | Alternator, monitor | Yeah (outside video) | Medium |
As you can see from the table, there is no universal solution. If the screen is even partially functional, the OTG and mouse bundle is the uncontested leader in simplicity and accessibility. For all-black screens, the only hope is for pre-configured sync or ADB debugging enabled.
It is important to understand that no software method can help if the motherboard itself or the memory controller is damaged, and in such cases it is already a complex hardware repair in the laboratory.
When a service center is needed
There are situations where self-extracting files can lead to permanent loss of data or aggravation of the breakdown. If the phone does not turn on, does not respond to the connection to the charger and does not make sounds, the problem lies in the hardware.
In service centers, specialists can temporarily connect the working display to your board to unlock the device and copy information, a service often cheaper than a full screen replacement, as it uses a demo module or used part.
⚠️ Warning: Do not attempt to disassemble the phone yourself unless you have experience. Damage to the battery plume or battery bloating can cause fire or permanent damage to the board, making data recovery impossible.
Also, if the phone has been in water, the moisture causes contact corrosion, and trying to power or connect a USB can cause a short circuit, in which case pre-cleaning in an ultrasound bath and diagnosis under a microscope are required.
💡
If the data is of critical value, the best solution is to use a dedicated service to temporarily install the desktop screen, rather than trying blind methods that can take a long time without guaranteeing success.
