The black or white screen on Xiaomi is one of the most frightening malfunctions that users face. The phone may not respond to pressing, not turn on or show only a monochromatic background with no signs of life. In 80% of cases, the problem is solved independently, but it is important to correctly diagnose the cause: it can be a software failure after the MIUI update, and a hardware failure (for example, a detached screen plume).
In this article, we will look at all possible scenarios, from basic actions like forced reboot to complex firmware manipulations via Fastboot. Particular attention will be paid to the models of Redmi Note 10/11/12, POCO X3/X4 and flagship Xiaomi 12/13, as they have specific “diseases” with the display. If your phone still responds to charging or vibration, the chances of recovery without loss of data are high.
1.Diagnostics: Why the screen turned black or white
Before you try to “resuscitate” your smartphone, identify the symptoms that may help narrow down the possible causes:
- 🔋 The screen is black, but the phone vibrates/sounds are there – most likely the problem is in the display backlight or graphics driver.
- ⚡ White screen after a fall or impact – mechanical damage to the plume or matrix (often found in the Redmi Note 9 Pro due to the fragile design).
- 🔄 Black screen after update MIUI — firmware failure or module conflict (typical for betta versions of HyperOS).
- 🔌 Phone does not respond to charging, screen is dead - possible failure of the power controller or battery.
If you drop your phone, pee it, or try to disassemble it before it breaks, there's a 95% chance it's a hardware malfunction. Otherwise, start with software.
⚠️ Warning: If the screen has turned white after changing the display in an informal service, do not try to sew the phone. Most likely, the master has improperly connected the plume or used a non-original matrix.
Fast Solutions: Reboot and Emergency Combinations
Start with the simplest of actions. Often, the black screen on Xiaomi is a system freeze that is eliminated by a forced restart.
Connect the charger (even if the phone is unresponsive)|Plug the Power button + Volume up for 15-20 seconds |If it doesn't work, try Power button + Volume down |Wait for 1-2 minutes - sometimes the phone wakes up with a delay-->
For non-removable models (all modern Xiaomis), the button combination is the only way to force the device to turn off. If the MI logo appears after the reboot, but it does not load further, go to the section on Recovery recovery.
If the phone vibrates when you press the buttons, but the screen is still black, try connecting it to the computer. USB-Device – the problem is precisely in the display or its backlight.

3.Recovery through Recovery Mode
If the phone turns on but doesn't load beyond the logo, or the screen blinks and goes out, a Recovery reset will help, which works even when the system files are damaged, but deletes all the data on the phone (photos, messages, apps).
Instructions for entering Recovery:
- Turn off your phone (if it is suspended).
- Press the Power button + Volume up until the Mi Recovery logo appears.
- Use volume buttons for navigation, power button for selection.
- Select Wipe Data → Wipe All Data (full reset).
- After reset, go to Reboot → Reboot to System.
If the Recovery phone also shows a black screen, but the buttons are working (navigation sounds are heard), try connecting it to your computer and flashing it through the Mi Flash Tool (more on that below).
⚠️ Note: On some models (POCO F3, Xiaomi 11T) After resetting via Recovery, you may need to re-activate your Mi Account. If you don't remember the password, the phone will turn into a brick!
4. Fastboot firmware: if the phone doesn't turn on
If the smartphone does not respond to any combination of buttons, but the computer “sees” it (defined as Qualcomm). HS-USB QDLoader 9008 in Device Manager, which is the firmware that's left over from Fastboot, and this method requires a PC, USB-cable and official firmware for your model.
Step-by-step:
- Download the Mi Flash Tool from Xiaomi’s official website and the firmware for your model (for example, tucana_global_images_... For the Redmi Note 8 Pro).
The process will take 5–10 If there's a mistake. anti_rollback, So you're trying to run an older version. MIUI, In this case, you need to look for firmware with the same or newer Anti-Rollback number (for example, ARB 4 For the Redmi Note 9).
What if the Mi Flash Tool can't see the phone?
5. backlighting problems: why the screen glows but nothing is visible
If you have a bright light on the screen that barely shows an image (like an icon or a time), but the backlight doesn't work, it's the backlight driver or the LED module that's at fault, and this problem often occurs after a drop or moisture hits.
Temporary solution (works on 60% of models):
- 🔦 Light up the screen with a flashlight at an angle – if the image is visible, the problem is precisely in the backlight.
- 🔄 Try to roll back the update. MIUI (If the problem has occurred after the update).
- 🛠️ If the phone is warranty, carry to the service - self-repair will deprive you of the right to free repairs.
For the Redmi Note 10 Pro and POCO X3 Pro models, there is a bug with a backlight driver after upgrading to MIUI 14.
- Enter the Recovery (as described above).
- Select Mount → System.
- Connect your phone to your PC and delete the file /system/vendor/lib/hw/light_hw_default.so (use ADB file manager with root rights).
- Reset the device.
⚠️ Warning: Deleting system files can cause your phone to run in an unstable way, and only do so if you are prepared for the consequences (e.g., broken light sensors).
6. Hardware breakdowns: when to carry in the service
If none of the software methods worked, it's probably the hardware problem.
| Symptoms. | Probable cause | Cost of repair (average) |
|---|---|---|
| White screen after fall | The matrix plume has detached or the glass has cracked. | 1 500–4 000 ₽ |
| Black screen, phone warms up | Short circuit on the board (often after charging) | 3 000–10 000 ₽ |
| The screen is flashing, stripes appear | Damaged graphics chip or matrix contacts | 2 000–6 000 ₽ |
| The phone does not respond to charging | Power controller is out of order | 2 500–8 000 ₽ |
For models Xiaomi 12/13 with AMOLED-screens repair is more expensive due to the high cost of the original matrix. If the phone is warranty, contact the authorized service center Xiaomi – self-repair voids the warranty.
If you decide to repair yourself, buy the original plume (for example, for the Redmi Note 11, Xiaomi 22041216C Display Flex Cable will suit). Cheap Chinese counterparts often break down after 1-2 months.
💡
Before visiting the service, take a picture of the IMEI phone (written on the box or under the battery) to help avoid replacing components with non-original ones.
7 Prevention: How to Avoid Black Screens in the Future
To minimize the risk of re-breaking, follow these guidelines:
- 🔋 Do not use cheap chargers – they can cause voltage surges and damage the power controller.
- 📱 Install updates MIUI Only through official channels (settings) → Updating the system).
- 💧 Avoid getting moisture, even if the phone has protection. IP53 (Like the Redmi Note 12, it will not save you from corrosion in prolonged contact with water.
- 🛡️ Use depreciation cases – they reduce the risk of damage to the plume when falling.
If you frequently experience screen glitches (flickering, spontaneous reboots), back up your data via Settings → Additional → Backup. In case of a crash, you can quickly restore contacts and photos to the new device.
💡
Check the status of the screen plume regularly, especially if the phone often falls. At the first sign of unstable work (shimmering, “snow” on the screen), contact the service - early repair is cheaper.
