You pick up your Xiaomi, and the screen stays black β no touch response, no lighting, no flashing notifications, and this is familiar to many owners of the brandβs smartphones, especially the Redmi Note 10/11, POCO X3/X4 or Mi 11. The causes can be software-based (firmwareware failure, application conflict) and hardware-based (steam damage, display failure). 80% of the time, the problem can be solved on your own β without going to the service center.
In this article, we will look at all possible scenarios, from basic actions like forced reboot to complex firmware manipulations via Fastboot. We will focus on saving data β photos, contacts and messages that may disappear when resets. You will also learn how to distinguish a software failure (which is treated with software) from hardware failure (requires repair).
First Actions: Checking the Obvious
Before you panic, rule out trivial reasons. Often, the black screen on Xiaomi is not associated with a breakdown, but with a temporary failure or a dead battery.
- π Charge the device. Connect the phone to the original charger (not via USB-You can wait 15 to 20 minutes. Even if the light doesn't burn, the battery could run out. Try using another charger or cable.
- π Forced reset. Press the power button. + Volume up for 10-15 seconds. On some models (e.g, POCO F3) The combination may be different: Nutrition + Loudness down.
- π± Physical damage check, check the case for cracks, dents, or traces of moisture, and if the phone falls or gets wet, there is a high risk of damage to the display plume.
If after charging and rebooting the screen still does not turn on, but the phone vibrates or makes sounds (for example, when connecting a charging), the problem is most likely software. If there is no reaction, it can be a hardware failure (battery, motherboard, display).

2. Diagnostics: hardware breakdown or software failure?
To avoid wasting time, it is important to determine the nature of the problem, and below is a table with signs that will help differentiate between software and hardware malfunctions.
| Sign. | Software failure | Hardware breakdown |
|---|---|---|
| Reaction to charging (indicator, vibration) | Aye (sounds, vibrations, LEDs) | No or partial (e.g., vibration only) |
| Connection to PC | Defined as a device (in Device Manager) | Not defined or displayed as an "Unknown Device" |
| Sounds when you press the buttons | There is (for example, the sound of locking/unlocking) | No or distorted |
| Prior developments | System update, application installation, resetting settings | Impact, fall, moisture, overheating |
If all the signs indicate a software failure, go to the next sections with instructions for recovery. If the problem is hardware, you can not do without repair. AMOLED-The plumes are extremely fragile with screens (for example, Mi 11 Ultra) and can be easily damaged if handled carelessly.

If the phone is responding to charging (vibrating or making sound) but the screen is still black, try connecting it to an external monitor via a USB-C β HDMI adapter. On some models (POCO F4 GT, Black Shark) this will work even if the graphics driver fails.
3. Recovery through Recovery Mode (without data loss)
If the screen is not working but the phone is on (for example, you can hear boot sounds), try to enter Recovery Mode, which will allow you to reset the cache or restart the system without deleting user data.
Instructions for most Xiaomi models:
- Turn off the phone (if it doesn't respond, press Power + Volume up for 20 seconds).
- Press Power + Volume up and hold for 10-15 seconds until you feel vibration.
- Release the buttons. In a few seconds, the Mi logo and the Recovery menu should appear (even if the screen is black, try pressing volume control buttons for navigation).
From the Recovery menu, select:
- π§Ή Wipe cache partition β Cache cleanup (safe for data).
- π Reboot system now - reboot.
If the cache is cleaned, the phone boots up, the problem is solved. If not, move on to the next step.

4. Connect to a PC and use the Mi Flash Tool
If the screen is not responding, but the phone is determined by the computer, you can try to flash it through the Mi Flash Tool, POCO X3 NFC For Mediatek (Redmi, etc.). 9A, POCO M3) You'll need another tool β SP Flash Tool.
Step-by-step:
- Download the official firmware for your model (choose the Fastboot version).
- Install Qualcomm drivers (e.g., via Mi Phone Manager).
- Unpack the firmware in a folder without Cyrillic symbols.
- Open the Mi Flash Tool, press Select and point the path to the firmware folder.
- Connect the phone to the PC, keeping Volume down + Power (Fastboot mode).
- In the Mi Flash Tool, press Refresh β the device must be determined. Select Clean all or Clean all and lock and press Flash.
What to do if the Mi Flash Tool can't see your phone?
Attention! If you choose Clean all and lock, the phone will be completely reset and the data deleted. If the screen doesn't work but the phone turns on, try Clean all first, which will save your files.
5. Alternative methods: ADB and Test Point
If the standard methods didn't work, there are more complicated options. Let's look at two of them:
Method 1: Teams ADB (if USB-debugging was included)
If you've activated it before USB-debugging in the developer settings, you can try to restart the phone through ADB:
adb devices
adb reboot recoveryIf the command is successful, the phone will reboot to Recovery Mode, where you can reset the cache or install the update via ADB sideload.
Method 2: Test Point (to unlock the bootloader)
On some models (Redmi 4X, Redmi 5A), you can use Test Point, a special point on the motherboard, the circuit of which puts the phone in EDL mode (emergency firmware), this method requires disassembly of the device and is suitable only for advanced users.

If you are unsure of your soldering skills, don't use Test Point. an error can cause your phone to fail completely.
6. When to carry in the service: signs of hardware breakdown
If none of the above methods worked, it's probably a problem with the iron, and here are some signs you should contact a service center:
- π₯ The phone does not respond to charging, there is no vibration and sounds.
- π When connected to a PC, it is defined as an βUnknown Deviceβ or not at all.
- π§ On the body visible traces of corrosion (infection of moisture).
- π§ The screen flashes or shows artifacts (strips, spots) before completely switching off.
The cost of repair depends on the model and type of breakdown:
- Replacement of the display plume: from 1,500 to 3,000 rubles.
- Screen replacement (with touchscreen): from 4000 to 12 000 rubles (on AMOLED more expensive).
- Maternity Board Repair: from 3 000 to 10 000 rubles.
Attention! If your Xiaomi is warranty-worthy, don't try to repair it yourself.A body opening or firmware through Fastboot will void warranty obligations.Course the official Xiaomi service center.
7 How to avoid future problems: Black screen prevention
To minimize the risk of re-turning off the screen, follow these guidelines:
- π Regularly update the firmware through Settings β The phone. β System updates. Updated versions. MIUI Corrections for critical bugs.
- π± Avoid installing applications from unverified sources (especially βacceleratorsβ and βoptimizers").
- π Keep the battery from running out completely. Optimal charge level is 20 to 80%.
- π‘οΈ Use depreciation cases and protective glasses β this will reduce the risk of damage to the screen when falling.
- π§ Do not leave your phone in wet areas (bathroom, kitchen) and do not use it in the rain.
If your Xiaomi has already βglutchedβ the screen before, it is worth backing up data through Settings β Additional β Backup and Reset or Mi Cloud. In the event of a repeated failure, you will not lose important information.
