When the screen of Xiaomiโs smartphone stops responding to touch or completely turns black, it always takes you by surprise. The biggest panic usually affects the user not because of the loss of the device itself, but because of the risk of losing important data, among which the first place is always occupied by phone numbers. Fortunately, the Android ecosystem and the shell of MIUI (or HyperOS) provide several layers of backup, which greatly simplifies recovery.
Before you go through a complex technical manipulation or bring a gadget into service, you need to assess the nature of the damage. If the display is simply broken, but the image and touchscreen are partially working, the algorithm will be the same. If the screen is completely black, but the phone vibrates when you call, the algorithm will be completely different. In this article, we will analyze all possible scenarios, from cloud services to forced image output.
The main goal is to access the contact database, which Xiaomi often stores in a secure partition, and the fastest way to restore is to log in to your account via the web interface if synchronization is enabled before the breakdown, and if the cloud is silent, you will have to use deeper diagnostic and PC connectivity tools.
Checking cloud storage Mi Cloud and Google Contacts
The first and most logical step is to check the companyโs servers. Xiaomi users often register a Mi Account on the first turn on, without thinking that this is when background synchronization starts. Even if you have never actively used the service, the basic data could be saved automatically.
To check, go to the official i.mi.com website from a computer or other smartphone. You will need to log in using your Mi Account and password. The site interface is an exact copy of the phone's menu, which makes navigation intuitive. If the synchronization was active, you will see your contacts in the appropriate section.
- ๐ฑ Go to the "Contact" section of the Mi Cloud website.
- ๐พ Select the โRestore Contactsโ option or simply copy the numbers.
- ๐ Make sure you log in to the same account as the broken device.
In parallel, you should check the backup of Google, and many users link the phone book to Gmail by default. Go to contacts.google.com and log in. If there are numbers, you just need to add this account to the new phone, and all the records will be restored instantly.
Using a USB-OTG adapter to control your phone
If the screen of the Xiaomi phone is black, but the touchscreen (touch layer) is physically intact and responds to presses, or if you see the image, but the sensor does not work, USB On-The-Go technology will help you.
You'll need a USB-OTG adapter cable (usually Type-C on USB-A). Connect your computer mouse to the charging phone connector. If the device is working, a cursor will appear on the screen (if it's even slightly glowing), and with your mouse you can unlock the phone, enter the pattern lock, and copy the data.
If the screen is completely black, but the phone is working, you can try the blind method. Connect the mouse, wait for the download, then click in the center of the screen (where the unlock button is usually) and make a swipe. If you're lucky, the phone will unlock, and you can connect it to the PC to copy files.
โ๏ธ What you need for the mouse method
It is worth noting that some Xiaomi models require the OTG feature to be enabled in the settings, although modern MIUI 12/13/14 and HyperOS firmware support it by default. If the mouse is not glowing and not working, it is possible that the port is damaged or the function is disabled at the software level.
Output of the image via HDMI adapter or USB-C
When the problem is a broken matrix (no image) but the sensor is working, or you need to visually monitor the process, it becomes indispensable to output the video signal to an external monitor, but there is an important technical nuance that not everyone knows about.
Most of Xiaomiโs budget and mid-range smartphones (Redmi, Poco series) are equipped with a USB 2.0 port that does not support video transmission. In such cases, the usual USB-C adapters to HDMI will not work. They require a special adapter with DisplayLink technology that processes video software.
Flagship models (series Xiaomi) 13/14, Mi 10/11/12) frequently USB 3.0/3.1/3.2 with support for the DisplayPort Alt Mode standard, any high-quality Type-C adapter will suit them. HDMI. Connecting your phone to a TV or monitor will show you a full copy of the screen and will be able to control the device if you also connect your mouse through the screen. USB-hub.
| Xiaomi model | USB version | Support for HDMI | Required adapter |
|---|---|---|---|
| Redmi Note 8-13 | USB 2.0 | No (indirectly) | DisplayLink (with driver) |
| Poco X3/X4/X5 | USB 2.0 | No (indirectly) | DisplayLink (with driver) |
| Xiaomi 11/12/13 | USB 3.2 | Yes. | Type-C to HDMI |
| Black Shark (all) | USB 3.x | Yes. | Type-C to HDMI |
What is DisplayLink?
Debugging with USB and working with ADB
For advanced users who had debugging enabled before the breakdown USB (USB Debugging, opens access to the most powerful recovery tool โ Android Debug Bridge (ADB). This method allows you to control the phone file system from your computer via the command line.
If you've given your computer permission to debug before, when you connect the cable, your PC will see the device. You'll need to install the Xiaomi USB Driver and the SDK Platform-Tools. Once connected, type the adb device command into the console. If the device is displayed with device status, you're in luck.
adb pull /data/data/com.android.providers.contacts/databases/contacts.db C:\Backup\This command will copy the contact database to the computer. However, on modern versions of Android, access to the /data/ folder without root permission is closed even to ADB. In this case, you can try to copy visible files or make a full backup, if the Android version allows.
โ ๏ธ Note: If you have never turned on the debugging USB It's not going to work in the Developer menu, and when you connect to a new PC, the phone may ask for a screen confirmation that you can't give when you're broken.
Data extraction via Mi PC Suite and recovery
The official Mi PC Suite (or its international version) sometimes allows you to see your phone files even if the screen is not working, provided that the file transfer mode has been active before, but more often than not, the security system blocks access before the screen is unlocked.
There's a way to log in to Recovery or Fastboot, and you can try to get into the Recovery menu by pressing the volume and power buttons, but in Recovery, you can't access your files, and it's more suitable for resetting if the data isn't important, but you just need to revitalize the machine.
Some users try to install custom Recovery (such as TWRP) through Fastboot to access files.This requires an unlocked bootloader. If the bootloader is locked (which is the default for all Xiaomi), this path is closed without prior unlocking, which is not possible with a idle screen.

If the phone turns on but the screen is black, try calling it. If it's a beep, it's working. If it's resetting or unavailable, it's probably the motherboard.
When professional repairs are needed
If none of the software methods worked, the last and most reliable option is to temporarily replace the display. It doesn't have to buy a new screen; service centers often have test modules. The wizard can plug the desktop screen into a plume so you can unlock the phone and copy the data.
In cases where the motherboard itself or the memory controller is damaged, data extraction becomes a difficult engineering task, requiring the soldering of memory chips to a donor board in a laboratory setting, an expensive procedure that only makes sense for really critical information.
Don't try to disassemble your phone yourself if you don't have experience, especially if the battery is damaged. A swelling battery can catch fire if a sloppy puncture occurs. You'd better leave the diagnosis to the professionals, warning them that the main goal is to save contacts, not repair them.
โ ๏ธ Warning: Beware of services that guarantee 100% retrieval of data from the sleeve boards without diagnosis.The honest wizard will first conduct a check and tell you about the risks.

The most reliable way to avoid data loss is to sync regularly with Mi Cloud or Google, which should be checked first.
